Preservative for cosmetics Salimix MCI
We present to your attention Preservative for cosmetic products Salimix MCI
This preservative is available in liquid form and is a mixture of two active components - isothiazolinones in an aqueous solution:
- methylchloroisothiazolinone (CAS-number 26172-55-4),
- methylisothiazolinone (CAS-number 2682-20-4).
It is completely soluble in water, lower alcohols and glycols, partially soluble in hydrocarbon mixtures.
Microbiological efficiency:
The preservative is effective against gram-positive and gram-negative bacteria, fungi and mold. It can be introduced into the final product at any stage of the manufacturing process, however early introduction is recommended to ensure the microbiological protection of the final product from the very beginning. Its effectiveness is reduced if bisulfites and secondary amines are present in the final product. The use of formaldehyde donors reduces the deactivation of the preservative by proteins.
