HYDROXYPROPYLTRIMONIUM HYDROLYZED MILK PROTEIN

Description

Hydroxypropyltrimonium hydrolyzed milk protein is a multifunctional ingredient derived from milk proteins, engineered for use in hair and skin care formulations. This quaternary ammonium compound combines the moisturizing and nourishing properties of milk proteins with the conditioning benefits of cationic ingredients.

The hydrolyzed milk protein component consists of smaller peptides and amino acids obtained through the breakdown of milk proteins. These elements can penetrate the hair shaft and skin barrier more effectively than intact proteins. The hydroxypropyltrimonium group attached to the hydrolyzed milk protein enhances its substantivity to hair and skin, allowing for prolonged contact and increased efficacy.

In hair care products, this ingredient functions as a potent conditioner, reducing static, improving combability, and enhancing overall manageability. For skincare applications, it provides moisturizing and film-forming properties, helping to improve skin hydration and texture. The cationic nature of the compound also contributes to its antimicrobial properties, potentially offering preservative-boosting effects in formulations.

Hydroxypropyltrimonium hydrolyzed milk protein is particularly beneficial for dry, damaged hair and skin, offering reparative and protective benefits. It is compatible with a wide range of formulations and is typically used at concentrations between 0.5% and 5%, depending on the specific application and desired effects.
