Application example of ε-Polylysine
COSMETICS|ε-Polylysine as a cosmetic raw material.
As a raw material for cosmetics, ε-Polylysine can be used in cosmetics such as hair treatments, serums, milky lotions, and foundations. ε-Polylysine is a natural product derived from an amino acid that is extremely safe and is also used as a food preservative. Compared to petrochemical-derived ingredients, it is hypoallergenic effect.
Hair care effects of ε-Polylysine
ε-Polylysine reduces dryness of hair
ε-Polylysine can suppress dryness of hair by adsorbing to hair.
Brushing your hair gives it a static charge. However, since ε-Polylysine is a cationic polymer, it can suppress dry hair by counteracting static electricity.
ε-Polylysine treated hair : After applying 1,000 ppm ε-Polylysine to the hair with an atomizer, the hair was dried.
Hair tresses conditioned at 20℃, and 30% RH were brushed 30 times and the spread of hair was measured.
ε-Polylysine reduces dryness of hair
ε-Polylysine reduces hair damage caused by bleaching. An electron micrograph of hair after bleaching is shown below. Bleaching reduces the moisture content of the hair and causes the cuticle to peel off due to static electricity. However, by adding ε-Polylysine to hair treatments and hair conditioners, the static electricity is negated and the repulsion between cuticles is alleviated. Therefore, the addition of ε-Polylysine can be expected to alleviate hair damage caused by bleaching.
ε-Polylysine-treated hair: The bleached hair was immersed in a 1,000 ppm ε-Polylysine aqueous solution for 5 minutes, then washed with water and dried.
