Additives

Preservatives Creams, gels and lotions require preservative to prevent bacterial growth.

May cause aggravation of eczema by

  • allergic reaction 
  • direct irritant effect

eg: - parabens - chlorcresol - sorbic acid - phenoxyethanol

Antioxidants Added to oil to prevent oxidation

eg: - Vitamin E

 

Emulsifiers Stabilise oil and water mixtures

Fragrances

The bath

Functions

Additives

AVOID SOAP! 

Instead use 
  • Diprobase cream  (pump dispenser) 
  • Unguentum Merck (pump dispenser) 
  • Wash E45 
  • Aqueous cream 
  • Emulsifying ointment
Followed by
  • a moisturiser (emollient)

 

This provides a surface film of oil which slows down the escape of water. Note: Less oily preparations contain more water, additives and preservatives, therefore use as OILY a preparation as possible. Avoid preparations with urea added - irritation (eg Aquadrate cream).
