Protesil

Seiwa Kasei Brand

Products:3

The Protesil series are hybrid polymers that combine three different types of substances, namely peptides, an alkyl group and silicone, all of which possess different properties. Since the peptide portion exhibits a hydrophilic property, while the alkyl group shows affinity to hydrocarbons and silicone demonstrates affinity for silicone oils, Protesil is highly compatible with various raw materials incorporated into cosmetics formulations. In addition, we are developing product counts for the Protesil series possessing different characteristics, depending on the balance of the three components in the polymer structure.
