What Is Dermol 600 Bath Emollient and How Does It Help Dry Skin?

 

If you live with eczema, psoriasis, or persistently dry skin, you'll know how much a daily bath can either help or hinder your skin. Dermol 600 bath emollient is a fragrance-free, antimicrobial bath additive designed to moisturise and soothe dry, itchy, and inflamed skin while you bathe. It contains a combination of liquid paraffin, isopropyl myristate, and benzalkonium chloride — ingredients that work together to hydrate the skin barrier and reduce the risk of bacterial colonisation, which is a known trigger for eczema flares. You can browse a wider range of options in our skin care collection if you're looking to build a complete routine.

Dry skin conditions affect millions of people in the UK. According to the NHS, eczema alone affects around 1 in 5 children and 1 in 10 adults at some point in their lives. Using an emollient regularly — including as a bath additive — is one of the most important steps in managing these conditions. Dermol 600 is available over the counter, making it easy to access without a prescription.

 

How Does Dermol 600 Bath Emollient Work on the Skin?

 

Dermol 600 works through a dual mechanism: it moisturises and it protects. When added to bath water, the emollient oils disperse and coat the skin during soaking, forming a thin occlusive film that helps to reduce transepidermal water loss (TEWL). This is particularly important in conditions like eczema, where the skin barrier is compromised and moisture escapes more readily than in healthy skin.

  • Liquid paraffin (25% w/v): An occlusive emollient that forms a protective layer on the skin surface, sealing in moisture.
  • Isopropyl myristate (25% w/v): A skin-conditioning agent that improves spreadability and helps the formula absorb without feeling overly greasy.
  • Benzalkonium chloride (0.5% w/v): An antimicrobial preservative that helps reduce bacterial load on the skin — particularly relevant for eczema patients, where Staphylococcus aureus colonisation is common and can worsen symptoms.

Together, these ingredients make Dermol 600 more than just a standard bath oil. The antimicrobial element sets it apart from many other emollient bath additives on the market.

 

Who Should Use Dermol 600 Bath Emollient?

 

Dermol 600 is suitable for adults, children, and babies (under medical supervision for infants) who experience dry, itchy, or inflamed skin. It's particularly well-suited to people managing long-term skin conditions who need a gentle, daily emollient as part of their skincare routine. You might also find our creams and ointments collection useful if you're looking for leave-on emollients to complement your bath routine.

  • People with eczema (atopic dermatitis) or contact dermatitis
  • Those with psoriasis or ichthyosis
  • Anyone with generalised dry or sensitive skin
  • Patients who prefer a fragrance-free, low-irritant bath product

Is Dermol 600 Bath Emollient Suitable for Long-Term Use and How Should It Be Stored?

 

Dermol 600 bath emollient is designed for regular, ongoing use as part of a daily emollient regimen. There is no clinical evidence suggesting harm from long-term use when applied as directed. The NHS recommends that emollients should be used consistently — even when the skin appears to have improved — to maintain the skin barrier and prevent flares.

Store Dermol 600 below 25°C, away from direct sunlight and out of reach of children. Do not use after the expiry date printed on the bottle. Once opened, use within the period indicated on the packaging. Keep the cap tightly closed when not in use to prevent contamination.

Specifications of Dermol 600 Bath Emollient

 

What Is Dermol 600 Bath Emollient and What Is It Used For?

 

Dermol 600 is a topical emollient bath additive used to manage dry, itchy, and inflamed skin conditions. It is indicated for eczema (atopic dermatitis), psoriasis, ichthyosis, and other conditions characterised by a compromised skin barrier. It works by adding moisturising oils to bath water, which coat the skin during soaking and help to restore hydration. The antimicrobial ingredient, benzalkonium chloride, also helps to reduce bacterial colonisation — a factor that can worsen eczema symptoms. It is available over the counter and does not require a prescription.

 

What Do You Need to Know Before Using Dermol 600 Bath Emollient?

 

Before using Dermol 600, read the following contraindications and warnings carefully:

  • Do not use if you are allergic to liquid paraffin, isopropyl myristate, benzalkonium chloride, or any other ingredient in the formulation.
  • Avoid contact with the eyes. If contact occurs, rinse thoroughly with water.
  • Bath and shower surfaces become very slippery when using emollient products — always use a non-slip mat and take care when getting in and out of the bath.
  • Emollients can soak into fabric and increase the risk of fire. Wash clothing and bedding regularly and keep away from naked flames.
  • Consult your GP or pharmacist before use in infants under 12 months.
  • If your skin condition worsens or does not improve after regular use, seek medical advice.

Drug interactions with topical bath emollients are not generally a clinical concern. However, note the following:

  • No significant drug interactions are known for Dermol 600 when used as directed.
  • If you are using other topical treatments (such as topical corticosteroids), apply them separately after bathing and patting the skin dry — do not mix products in the bath water.

 

How Should You Use Dermol 600 Bath Emollient?

 

Using Dermol 600 correctly makes a real difference to how well it works. Follow these steps each time you bathe:

  1. Fill the bath with warm (not hot) water — hot water can strip the skin of natural oils and worsen dryness.
  2. Add 15–30ml (approximately 1–2 capfuls) of Dermol 600 to the bath water.
  3. Stir the water to disperse the emollient evenly.
  4. Soak for 10–20 minutes, allowing the oils to coat the skin.
  5. Carefully step out of the bath — surfaces will be slippery.
  6. Pat (do not rub) the skin dry gently with a soft towel, leaving a slight film of moisture on the skin.
  7. Apply any prescribed leave-on emollient or topical treatment immediately after drying.
Indication Age Group Dose Frequency
Eczema / dry skin Adults 15–30ml per bath Once or twice daily
Eczema / dry skin Children (1 year+) 5–15ml per bath Once daily
Eczema / dry skin Infants (under 12 months) Under medical supervision only As directed by GP

 

What Are the Possible Side Effects of Dermol 600 Bath Emollient?

 

Dermol 600 is generally well tolerated. Side effects are uncommon, but it's worth knowing what to look out for. If you experience any unexpected reaction, stop use and speak to your pharmacist or GP.

Common side effects:

  • Mild skin irritation or stinging, particularly on broken or very sensitive skin
  • Temporary redness at the site of application

Less common side effects:

  • Allergic contact dermatitis (rash, itching, or swelling) — rare but possible with benzalkonium chloride sensitivity
  • Folliculitis (inflammation of hair follicles) with prolonged use of occlusive emollients — seek medical advice if this occurs

The most significant safety concern with Dermol 600 is not a skin reaction — it's the risk of slipping. Emollient residue makes bath and shower surfaces extremely slippery. Always use a non-slip bath mat and supervise children at all times. If you're also managing other skin concerns, our creams and ointments collection includes a range of complementary topical treatments.

 

How Should You Store Dermol 600 Bath Emollient?

 

  • Store below 25°C in a cool, dry place.
  • Keep away from direct sunlight and heat sources.
  • Keep the bottle tightly closed when not in use.
  • Keep out of the reach and sight of children.
  • Do not use after the expiry date printed on the bottle.
  • Do not store in the bathroom if temperatures regularly exceed 25°C.

For families managing eczema in children, it may also be worth exploring our baby and toddler collection for additional gentle skincare products suitable for young skin.

Frequently Asked Questions

Where can I buy Dermol 600 Bath Emollient online in the UK?

You can buy Dermol 600 Bath Emollient online from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £12.00. It is available without a prescription as an over-the-counter emollient. Simply add it to your basket and it will be dispatched directly to your door.

How does Dermol 600 Bath Emollient work in the body?

Dermol 600 works topically — it does not enter the bloodstream. When added to bath water, the liquid paraffin and isopropyl myristate coat the skin surface, forming an occlusive film that reduces transepidermal water loss. The benzalkonium chloride component provides antimicrobial action, helping to reduce bacterial colonisation that can trigger eczema flares.

How do I use Dermol 600 Bath Emollient step by step?

Add 15–30ml of Dermol 600 to a warm bath and stir to disperse evenly. Soak for 10–20 minutes, then carefully step out — the bath surface will be slippery — and pat your skin dry gently with a soft towel. Apply any leave-on emollient or prescribed topical treatment immediately afterwards for best results.

What is the correct dose of Dermol 600 for adults?

For adults, the recommended dose is 15–30ml (approximately 1–2 capfuls) added to a full bath of warm water. This can be used once or twice daily depending on the severity of your skin condition. Always follow the instructions on the packaging or as directed by your GP or pharmacist.

Is Dermol 600 Bath Emollient safe for babies and young children?

Dermol 600 can be used in children aged 1 year and over, using a smaller amount of around 5–15ml per bath. For infants under 12 months, always consult your GP or pharmacist before use. An adult must supervise children at all times due to the slippery bath surface created by the emollient oils.

Can I use Dermol 600 Bath Emollient for psoriasis?

Yes, Dermol 600 is suitable for use in psoriasis as well as eczema and other dry skin conditions. It helps to hydrate and soothe the skin, reducing dryness and scaling. However, it does not treat the underlying cause of psoriasis, so you should continue any prescribed treatments alongside it.

What are the side effects of Dermol 600 Bath Emollient?

Side effects are uncommon but may include mild skin irritation, temporary redness, or — rarely — an allergic reaction to benzalkonium chloride. The most significant practical risk is slipping in the bath due to the oily residue left on surfaces. Always use a non-slip bath mat and take care when stepping out of the bath.

How do I manage side effects of Dermol 600 Bath Emollient?

If you experience skin irritation or a rash, stop using Dermol 600 and speak to your pharmacist or GP. To manage the slipping risk, always place a non-slip mat in the bath before use and supervise children at all times. Clean the bath thoroughly after each use to remove any oily residue.

Who is eligible to use Dermol 600 Bath Emollient?

Dermol 600 is suitable for adults and children with dry, itchy, or inflamed skin conditions including eczema, psoriasis, and ichthyosis. It is not suitable for anyone with a known allergy to any of its ingredients. Speak to your GP before using in infants under 12 months or if you are pregnant or breastfeeding.

What happens if I use too much Dermol 600 in the bath?

Using more than the recommended amount will not improve the emollient effect and will simply make the bath surface more slippery, increasing the risk of a fall. Stick to the recommended 15–30ml for adults. If you accidentally ingest any of the product, contact NHS 111 or your nearest A&E immediately.

What are the alternatives to Dermol 600 Bath Emollient?

Alternatives include Oilatum Bath Additive, Balneum Bath Oil, and Aveeno Dermexa Bath & Shower Oil, all of which are emollient bath additives for dry skin. Unlike Dermol 600, most alternatives do not contain an antimicrobial ingredient. You can explore a range of options in our skin care collection.

How long can you use Dermol 600 Bath Emollient for?

Dermol 600 can be used as part of a long-term daily skincare routine — there is no set maximum duration for emollient use. The NHS recommends using emollients consistently, even when the skin appears to have improved, to maintain the skin barrier and prevent flares. Review your treatment with your GP or pharmacist at least annually.

Does Dermol 600 Bath Emollient contain steroids?

No, Dermol 600 does not contain any corticosteroids. It is a plain emollient bath additive with an antimicrobial ingredient. If your skin condition requires a steroid treatment, this would need to be prescribed separately by your GP and applied as a leave-on product after bathing.

Is Dermol 600 Bath Emollient safe to use during pregnancy?

Dermol 600 is applied topically and is not expected to pose a risk during pregnancy, but you should always consult your GP or midwife before starting any new treatment while pregnant. Emollients are generally considered safe for use in pregnancy for managing dry skin conditions. Your healthcare provider can advise on the most appropriate option for you.

What are the latest studies on emollient bath additives for eczema?

Research into emollient bath additives has evolved in recent years. A notable UK study (the BATHE trial) questioned whether bath additives provide additional benefit over standard emollient creams alone for childhood eczema. However, clinical guidelines still support their use as part of a broader emollient regimen, particularly where patients find them helpful for symptom management. Speak to your GP or dermatologist for personalised advice.

How Should You Use Dermol 600 Bath Emollient?

Using Dermol 600 correctly is straightforward, but a few simple steps make a real difference to how well it works. Always use warm — not hot — water, as hot water can strip the skin's natural oils and worsen dryness and irritation.

What Is the Correct Dose of Dermol 600 Bath Emollient?

The dose varies depending on age and the severity of the skin condition. Always follow the instructions on the packaging or as directed by your GP or pharmacist. Do not exceed the amounts listed below.

When Is the Best Time to Use Dermol 600 Bath Emollient?

There is no single "best" time, but many people find that bathing in the evening works well — it allows the skin to absorb moisture overnight when the body is at rest. Consistency matters more than timing. Using Dermol 600 at the same time each day helps to establish a routine, which is particularly important for managing chronic conditions like eczema where regular emollient use is key to preventing flares.

If you bathe in the morning, apply a leave-on emollient afterwards to maintain hydration throughout the day. Avoid bathing immediately before going out in cold weather, as freshly moisturised skin can be more sensitive to temperature changes.

How Long Can You Use Dermol 600 Bath Emollient For?

Dermol 600 is suitable for long-term, ongoing use. The NHS recommends that emollients should be used continuously — even during periods when the skin appears clear — to maintain the skin barrier and reduce the frequency of flares. There is no clinical evidence of harm from prolonged use when the product is applied as directed.

Review your emollient regimen with your GP or pharmacist at least once a year, or sooner if your skin condition changes significantly. If you notice your skin is no longer responding as well as it used to, a different formulation may be more appropriate for your needs.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Dermol 600 Bath Emollient?

Dermol 600 is generally very well tolerated, and most people use it without experiencing any adverse effects. That said, as with any topical product, some individuals may notice mild reactions, particularly when first starting use or if the skin is already broken or very sensitive.

  • Mild stinging or burning sensation on broken or very sensitive skin
  • Temporary redness or warmth at the site of contact
  • A feeling of greasiness on the skin immediately after bathing

What Are the Less Common Side Effects of Dermol 600 Bath Emollient?

Less common reactions are rare but worth being aware of. If you notice any of the following, stop using the product and speak to your pharmacist or GP before continuing.

  • Allergic contact dermatitis — presenting as a worsening rash, intense itching, or localised swelling, potentially related to sensitivity to benzalkonium chloride
  • Folliculitis — inflammation of the hair follicles, which can occasionally occur with prolonged use of occlusive emollients, particularly in areas with dense hair follicles
  • Increased skin sensitivity or a paradoxical worsening of dryness in a small number of individuals

What Are the Serious Side Effects of Dermol 600 Bath Emollient?

Serious side effects from Dermol 600 are extremely rare. However, a severe allergic reaction (anaphylaxis) is theoretically possible with any product containing benzalkonium chloride, though this is exceptionally uncommon with topical use. Signs of a severe allergic reaction include sudden swelling of the face, lips, or throat, difficulty breathing, or a widespread skin rash. If you experience any of these symptoms, call 999 immediately.

There is also an important non-dermatological risk: emollient residue on bath and shower surfaces creates a significant slip hazard. Falls in the bath are a real and preventable risk — always use a non-slip mat and supervise children and elderly individuals at all times.

What Should You Do If You Experience Side Effects of Dermol 600?

If you develop a mild skin reaction such as redness or irritation, stop using Dermol 600 temporarily and allow the skin to settle. Rinse the affected area with cool water. If the reaction is more severe, persistent, or accompanied by swelling or breathing difficulties, seek urgent medical attention. You can report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Dermol 600 Bath Emollient Interact With Other Medicines?

No significant drug interactions are known for Dermol 600 when used as a bath additive. However, if you are using other topical treatments — such as topical corticosteroids, calcineurin inhibitors, or medicated creams — do not add them to the bath water alongside Dermol 600. Apply leave-on treatments separately after bathing and patting the skin dry, to ensure they are absorbed correctly and at the right concentration. If you are unsure about combining treatments, speak to your pharmacist for personalised advice.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
