13.2.1 Emollients

Self-Care: Those people with dry skin without a diagnosed dermatological condition requesting a general dry skin moisturiser should purchase these over the counter.

NHS England (NHSE) has published new prescribing guidance for various common conditions for which over-the-counter (OTC) items should not be routinely prescribed in primary care (quick reference guide).

Many of these products are cheap to buy and are readily available OTC along with advice from pharmacies. Some self-care medicines are available from shops and supermarkets.

Emollients are essential in the management of diagnosed dermatological conditions, such as eczema or psoriasis, and their regular use can alleviate symptoms and reduce flare ups; prescribing of emollients should be reserved for these patients.

Emollients should be used as a soap substitute, as normal soap tends to dry the skin. It is important to use a product which suits the patient and is effective for them. Evidence from randomised controlled trials to support the use of one emollient over another is lacking, therefore selection is based on the known physiological properties of emollients, patient acceptability, dryness of the skin, area of skin involved and lowest acquisition cost.

Careful explanation of how to use emollients, as well as how much to use, may encourage compliance. Emollients should be smoothed on in the direction of hair growth. They should not be rubbed in. They should be continued to be used even after the skin condition has cleared, if the clinical condition justifies continued use.

Sufficient quantities should be prescribed to allow liberal application as frequently as required, once patient preference is established:

  • Adults would normally require at least 250g of emollients per week
  • Children would normally require at least 125g of emollients per week

MHRA Drug Safety Update (April 2016): Fire risk with paraffin-based skin emollients on dressings or clothing:

  • Patients are advised not to: smoke; use naked flames (or be near people who are smoking or using naked flames); or go near anything that may cause a fire while emollients are in contact with their medical dressings or clothing
  • Patients should change clothing and bedding regularly—preferably daily—because emollients soak into fabric and can become a fire hazard
  • The risk is greater when these preparations are applied to large areas of the body, or when dressings or clothing become soaked with emollient

MHRA Drug Safety Update (December 2018): Emollients: new information about risk of severe and fatal burns with paraffin-containing and paraffin-free emollients:

  • There is a fire risk with all paraffin-containing emollients, regardless of paraffin concentration, and it also cannot be excluded with paraffin-free emollients. A similar risk may apply for other products which are applied to the skin over large body areas, or in large volumes for repeated use for more than a few days
  • Be aware that washing clothing or fabric at a high temperature may reduce emollient build-up but not totally remove it

Pot Hygiene: Where possible, prescribe an emollient with a pump dispenser to minimize the risk of bacterial contamination. When supplying patients with pots of emollient, it is important to educate them about the hygiene required. Patients should be advised to decant from the pot onto plate/bowl using a spoon. Hands should not be put into the pot as this will lead to the introduction of foreign particles.

All primary and secondary care prescribers should where possible select the emollient with the lowest acquisition cost from the range available in the agreed preferred product list.

For most types of emollient, several products have been included to allow for patients to try a number of options, before clinicians consider non-formulary options.

Ointments

Ointments are good for very dry, thickened skin and night-time use as they are greasy, thick and very moisturising; however, they are not always acceptable to patients due to their greasiness. They should be applied every 6–8 hours.

Zeroderm®
  • Ointment (£4.10 = 500g tub)
  • Paraffin content: 70% (White soft paraffin 30%, Liquid Paraffin 40%)

Gels are relatively light and non-greasy, despite having reasonably high oil content. They should be applied every 3–4 hours.

Isomol®
  • Gel (£2.92 = 500g flexi-dispenser), (£1.99 = 100g tube)
  • Paraffin content = 15% (Liquid paraffin 15%)

Creams

Creams are not greasy and are quite easy to spread over sore and weeping skin; so many patients prefer them to ointments for daytime use. They should be applied every 3–4 hours.

Epimax®
  • Cream (£2.49 = 500g flexi-dispenser), (£0.75 = 100g tube)
  • Paraffin content: 21% (White soft paraffin 15%, Liquid paraffin 6%)

Creams - colloidal oatmeal-containing

Some patients may to prefer an emollient cream containing colloidal oatmeal.

  • Possible sensitisers: Benzyl alcohol, Cetylstearyl alcohol, Isopropyl palmitate
  • Similar in formulation to Aveeno cream (non-formulary)

Creams - urea-containing

Urea, which acts as a humectant, draws water into the skin. These products are not indicated for routine use as they are more expensive but may be useful for very dry conditions such as ichthyoses and for keratosis pilaris (used sparingly). They should be applied every 6-8 hours.

5% Urea content
ImuDERM®
  • Cream (£6.55 = 500g pump dispenser) (contains urea 5% & glycerine 5%)
  • Paraffin content: Less than 20% (Liquid paraffin less than 20%)
  • Potential sensitisers: Benzyl alcohol, Cetostearyl alcohol, Lactic acid, Phenoxyethanol Potassium Sorbate

  • Cream (£4.41 = 100g tube) (contains urea 10%)
  • Paraffin content: 28.15% (White soft paraffin 28.15%)
  • Potential sensitisers: Isopropyl myristate
  • For larger volumes of 10% urea containing creams (i.e 500g) prescribe Flexitol 10% Urea, as this represents better value for money
Flexitol® 10% Urea
  • Cream (£11.77 = 500g pump dispenser) (contains urea 10%)
  • Paraffin content: 1%-10% (Light liquid paraffin 1%-10%)

  • For smaller volumes of 10% urea containing creams (i.e 100g) prescribe Hydromol Intensive 10% Urea, as this represents better value for money

Lotions and Sprays

Lotions are quick to apply but take a little longer to dry. Useful for hair-bearing areas prone to folliculitis. They should be applied every 6-8 hours.

E45®
  • Lotion (£4.50 = 500ml pump dispenser)
  • Paraffin content: 14% (White soft paraffin 10%, Liquid paraffin 4%)
  • Potential sensitisers: Benzyl alcohol, Lanolin, Parabens

Sprays are an option for some patients where the emollient can be applied without touching the skin; this may be an advantage where the patient cannot reach the affected area or where touching the skin may be detrimental.

Emollin®
  • Spray (£4.00 = 150ml aerosol), (£6.39 = 240ml aerosol)
  • Paraffin content: 100% (White soft paraffin 50%, Liquid Paraffin 50%)
  • Potential sensitisers: No known sensitisers

Bath and shower preparations

A multicentre pragmatic parallel group RCT looking at emollient bath additives for the treatment of childhood eczema (BATHE, 2018) showed that there was no evidence of clinical benefit for including emollient bath additives in the standard management of childhood eczema.

Emollients can still be used for treating eczema and these emollients can still be used as soap substitutes. Any emollient listed in the formulary ( except White Soft Paraffin 100%, and Liquid Paraffin 50% & White Soft Paraffin 50%) can be applied before bathing, showering or washing, or while in the water.

Patients should be aware of the potential dangers of slipping when using emollients in a bath or shower, or on a tiled floor. Parents may also wish to be cautious when removing children from the bath.
