AMISAFE® LL-DS-22Amino Acid Based Texture Modifier

AMISAFE® LL-DS-22 is an amino acid based texture modifier derivedfrom L-Lysine, Lauric acid and Sebacic acid.The uniqueness of AMISAFE® LL-DS-22 is originated from its gemini-type surfactant chemical structure and properties as a hydrogelator. In foaming cleansing products AMISAFE® LL-DS-22 functions as a foam booster and imparts characterstic silky smoothness to dry skin and hair.

Molecular Structure

● Facial wash ● Hair shampoo ● Body wash ● Hair conditioner

Applications

● AMISAFE® LL-DS-22 forms hydrogel by a threedimen- sional network of nanofibers at around pH 6. (right photo)

● AMISAFE® LL-DS-22 works as a foam booster of surfac-tants by stabilizing foam structure with small dosage.

● AMISAFE® LL-DS-22 gives smoothness to skin and hair.

Characteristics

● Foam boosting effect for various surfactantsBy adding AMISAFE® LL-DS-22 “hydrogel”more efficient foam boosting effect isobtained.

With AMISAFE® LL-DS-22Test Formulas

● Sensory test of facial wash

● Hair tactile properties

AMISAFE® LL-DS-22 improves lather speed, foam volume of a paste-type facial wash, as well as silky smoothness of dry skinfeel.

By addition of AMISAFE® LL-DS-22 to a hair shampoo, hair surface hydrophobicity and dry hair smoothness are improved.
