Description
Chemie SB is a blend specially designed for recommended for inclusion in both leave on and rinse off applications in the range 0,2 to 1,0% and should be added to the aqueous phase with mixing as early as possible in the formulation process. It is tolerant to temperatures up to 80°C and pH up to 9. However, to ensure maximum preservation efficacy the pH of the final product should be adjusted to below 5,5. Because of the large variation in the composition of cosmetic products it is important that the preserving effectiveness is evaluated in the final formulation using appropriate microbial challenge tests.
The preservative activity of Chemie SB is maximised at pH4.5 to 5.0 where the actives are in their undissociated states as their respective organic acids. However, at pH in the range 5 to 5.5 this combination can still be used with good results. Benzoic and sorbic acid act in a complementary nature by suppressing the growth and spore germination of bacteria and moulds respectively.
It is suitable to be used in leave on and rinsed off product and especially suitable in baby products.
