Product Background: Wheat protein is rich in acidic amino acid as with soy protein and also has a slight amount of cystine. It brings light texture as compared to soy protein.

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.

Technical Details & Test Data

Mechanism of Action
Verification Tests: 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.
