Soy protein is distinct from animal protein such as collagen and keratin in that it has glutamic acid and aspartic acid 30% of itself. It brings high moisturizing property as well as collagen but brings different texture. Additionally, it produces moist feeling and prevents unmanageable hair.
Silk is a fiber made of two proteins, mainly fibroin but also sericin. Fibroin has a unique amino acid composition. Glycine, alanine and serine which have small molecular weights and simple chemical structures account for 90%. These amino acids are known to be arranged in β-sheets which greatly contributes to silk well-known shiny appearance and smoothness.
Promois SIG series is a derivative bonded with a silyl group at the N-terminal of the hydrolyzed protien (peptide). It is a "Heat active ingredient", having thermal reactive unique feature, that is different from other peptide derivatives.
Coated layer on the hair surface is formed by the Promois SIG-treatement and heating processes using hair-dryer or hair-iron.
"Heat active effect" , Protecting hair from damages caused by heat and improving the hair strength and texture, is exerted by the layer.

Heat active effect of Promois SIG series
-
Formation of coated layer on the hair surface
Evaluation method:
Damaged hairs treated by Promois SIG were used in this test. Hair surface of test hairs with heating process by hair dryer (65°C, 5min) or without heating process were observed by scanning electron microscope (x 2000).
Control:Damaged hair treated with ion-exchanged water
-
Improvement of smoothness
Evaluation method:
Damaged hairs treated by Promois SIG were used in this test. Smoothness of test hairs with heating process by hair dryer (65°C, 5min) or without heating process were evaluated by friction tester.
Control:
Damaged hair treated with ion-exchanged water.
-
Improvement of hair strength
Evaluation method:
Damaged hairs treated by Promois SIG wre used in this test. Hair strength of test hairs with heating process by hair iron (180°C, 10sec) or without heating process were evaluated by hair rheology analyzer.
Control:
Damaged hair treated with ion-exchanged water.
