Protesil
Protein Hybrid Polymer
Protesil is a multifunctional hybrid polymer composed of 3 components: a Protein (hydrolyzed protein) moiety, a Silicone backbone, and Alkyl groups.
There are 2 types available based on the protein moiety: Protesil LH (Silk Protein) and Protesil JLH (Botanical Protein). The presence of the protein component provides a high affinity for hair, allowing it to form a thin, uniform coating on the hair surface. As a result, excellent performance can be achieved even at low use levels.
Protesil prevents Build-up of conditioning polymers and keeps beautiful hair!
Protesil functions as a treatment ingredient for Build-up Hair* with “No Build-up & Build-up prevention” effect.
Verification
We tested non-silicone-buildup effect of Protesil.
Damaged hair was treated with commonly used shampoo. Then, it was treated with conditioner containing silicone (conditioning polymers) or conditioner containing both silicone and Protesil LH ten times. Amounts of Si were measured by EDS (Instrument of energy-dispersive X-ray spectroscopy).
*A condition in which ingredients excessively accumulate on the hair surface, leading to deterioration of the hair surface condition.
Hair color Boost and Keep! Continue the vivid hair color.
Just a small amount of Protesil can coat hair thinly and evenly with a silky film, curbing the irregular reflection of light, it helps realize a more vivid and translucent hair color and prevents color fading.
Mechanism
We show how to boost hair color-shade and prevent color fading.
Protesil coats hair surface uniformly, as a result, the irregular reflection of light decreases and vivid color keeps long. In addition, coating film maintains color component inside the hair, it helps realize a long-term maintenance dyed hair color.
