  • Doublebase Emollient Bath Additive is a skin treatment for you to add to your bath water when bathing.
  • It helps treat dry or chapped skin conditions that may also be itchy, red and sore.
    Common examples include:
    • psoriasis (scaly, pink patches of skin), elderly pruritus (itchy skin due to ageing), ichthyosis (abnormal scaly skin), various forms of eczema, dermatitis and other dry skin disorders.
  • All age groups can use Doublebase Emollient Bath Additive, including babies.
  • The active ingredient in this product is liquid paraffin. This active ingredient is an emollient. When added to your bath water the product helps to:
    • soften, moisturise and protect your skin by trapping moisture in the skin and restoring the normal protective function of the skin.
    • prevent the skin-drying and irritant effects that can be caused by bathing and by the soaps, foaming additives and fragrances used in ordinary bath products.
  • This product can be used in addition to any other emollients or treatments your doctor, pharmacist or nurse may have given or prescribed for you to treat your dry skin condition.


Do not use Doublebase Emollient Bath Additive if you are allergic (hypersensitive) to liquid paraffin or any of the other ingredients of Doublebase Emollient Bath Additive listed in Section 6.

Warnings and precautions

Do not smoke or go near naked flames - risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.

Take special care when using this product:

  • it can make your bath slippery, so be careful to avoid slipping over when getting into and out of your bath. Be careful when handling babies and young children.
  • after use, clean out the bath with a suitable detergent to remove any remaining greasiness (wearing protective gloves to avoid irritating your hands).
Using other medicines

This product is not known to affect, or to be affected by, other medicines.

Pregnancy and breast-feeding

This product can be used during pregnancy and while breast-feeding. The ingredients have been in widespread use in this and similar preparations for many years, without reports of problems. However, safety trials have not been conducted.

Doublebase Emollient Bath Additive contains cetostearyl alcohol

Cetostearyl alcohol may cause local skin reactions (e.g. contact dermatitis).


For maximum benefit, add this product to your bath water every time you have a bath.

For adults, children and the elderly:
  • Shake the bottle before use.
  • Add approximately 15 to 20 ml (1½ to 2 inner capfuls) to a normal-sized bath filled with water to a depth of roughly 20 cm (8 inches).
  • Get into the bath and cover the affected areas of skin with the bath water.
  • Soak for 10 to 20 minutes.
  • Pat the skin dry with a soft towel.
  • Avoid rubbing with the towel because this makes dry skin conditions worse.
For babies and children:
  • Shake the bottle before use.
  • Add approximately 5 to 10 ml (½ to 1 inner capful) to a small bath of water or wash basin.
  • Submerge the affected areas of skin.
  • Soak for 10 to 20 minutes.
  • Alternatively, repeatedly sponge the water over the affected skin areas.
  • Pat the skin dry with a soft towel.
  • Avoid rubbing with the towel because this makes dry skin conditions worse.

You may prefer to use your normal soap as well as Doublebase Emollient Bath Additive when bathing. As a general rule, however, the use of normal soaps and foaming bath products (even those labelled “moisturising”) is best avoided, or at least kept to a minimum. Ideally, a fragrance-free emollient “soap substitute” should be used instead, despite the fact that this type of product does not foam or lather.

If you forget to use Doublebase Emollient Bath Additive

Do not worry if you occasionally forget to use it, just carry on using the product as described the next time you bathe.

This product has been specially designed for use on dry or problem skin. However, in rare cases it can cause skin irritation (mild rashes) or allergic skin reactions on extremely sensitive skin. These rare effects tend to occur during or soon after the first few uses.

Stop using this bath additive and tell your doctor, nurse or pharmacist:

  • if your skin condition seems to look or feel worse.
  • if any of the side effects get worse, or you notice any other side effects not mentioned in this leaflet.

If this product is accidentally swallowed, its oily ingredients may cause diarrhoea.

If this happens:

  • treat the symptoms as you would deal with any case of diarrhoea.
  • drink plenty of water.
  • do not attempt to cause vomiting.

  • Emollients help soften, moisturise and protect the skin. They play a central role in the treatment and management of dry skin conditions. For maximum effect, they should be applied regularly and as often as needed.
  • When bathing, try to use warm, not hot, water and avoid staying in the bath for long periods. This could make dry skin conditions worse.
  • Try to avoid using normal soaps or bath additives (even those labelled “moisturising”). This is because they tend to dry and irritate the skin. Avoid using products containing fragrances, as these can also cause skin problems. You should try to use a fragrance-free emollient “soap substitute” instead. This type of product will not foam or lather but will be better for your dry skin condition.
    Breaking the itch-scratch cycle
    Some dry skin conditions like eczema and dermatitis are itchy, and can be quite sore. Although scratching relieves the itching for a short while, it further damages the skin. Badly scratched skin easily gets infected. This makes it itchier and the urge to scratch becomes even greater. It is better if scratching can be avoided by reducing the itching. The regular use of emollients or moisturisers can help with this.
