A lot of emollients used in Eczema management are marked ACBS. What does this mean?
Advisory Committee of Borderline Substances:
In certain conditions, some foods and toiletry preparations have the characteristics of drugs. A board known as the Advisory Committee on Borderline Substances (ACBS) advises on the circumstances in which these products may be regarded as drugs, and if prescribed in accordance with their advise, prescriptions need to be marked ACBS.
A lot of emollients are ‘leave-on’ preparations like moisturisers: Just rub these in the direction of the hairs and leave on. Aqueous cream should be used as a soap substitute and is rinsed off after application. Why is it not used as a leave-on prep?
Aqueous cream may increase the risk of skin reactions if left on particularly in eczema, often within 20 mins of application.
It is Sodium Lauryl sulphate in the cream that can cause this!
NB: emulsifying ointment is also used as a soap substitute in the bath

Enhance penetration of the skin- makes them more potent
