Measuring the mildness
of cleansers
A recognised method of assessing whether a product will
irritate the skin is the Forearm Controlled Application
Test (FCAT).
This involves using an exaggerated
washing procedure to measure irritation for five consecutive
days. The dryness and/or redness of the skin is recorded
on day 1, using a standardised scale, and again on day
5. Measurements of skin hydration are taken at the same
time.
The results can be compared with the
results for a known mild surfactant product.
Toners
Skin toners are used after cleansing to ensure complete
removal from the skin of all cleansing preparations,
and also after a face mask to remove all traces of the
mask. They are based on plant extracts; those for people
with oily skin can contain up to 20% of alcohol. |
