Pseudo Collagen
1) Aromantic Recipes usually
contain dosages for preservatives that are appropriate for Parabens (normally
10 drops). If you are using Preservative K instead of Parabens, then
increase the dosage from 10 to 18 drops.
2) If using Preservative K as your Preservative in your Recipes,
you must add 0.5% of Lactic Acid after you’ve added the in the
Fourth Stage, or at the end of the Recipe if
there is no Fourth Stage.
3) As a result of the use of Potassium Sorbate, Preservative
K raises the pH of the product (alkaline reaction). After it has been
incorporated into the cosmetic product, the pH value of the product therefore
has to be adjusted. After having added all of your raw materials and
Preservative K, then test the pH. If it is over 5.5, add from 0.3 - 0.5%
Lactic Acid and retest the pH. When the pH is under 5.5, your products
will keep for 1.5-3 years, depending on the product. When testing a cream,
smear the Litmus Paper with the cream and
scrape it off after 1 minute to reveal the pH. If you have a liquid product
e.g. Shampoos, simply dip the Litmus Paper in for 30 seconds and the
colour will be easily revealed.
