Milk Protein for Increased Skin Hydration in Rinse-off Applications

TRI-K Industries added a milk protein to its NPNF (non-paraben, non-formaldehyde) line that increases skin hydration in rinse-off products. Milk Tein NPNF (INCI: Hydrolyzed Milk Protein) is made from food-grade milk powder, with a high level of amino acids.

The company previously offered the milk protein as Milk-Tein NL (INCI: Hydrolyzed Milk Protein), which has anti-irritant and protection benefits. These benefits are also found in the NPNF version; however, the company's recent rinse-off data supports the use of Milk Tein NPNF to improve and retain skin moisture.

The milk protein is a substantive film-former that immediately increases skin hydration but also improves the skin's moisture retention with repeated use in rinse-off applications. It prevents dry skin caused by surfactants while protecting skin and improving skin feel. The protein is gentle and can be used on delicate skin.

The ingredient is recommended for rinse-off applications such as facial wash, body wash, shower gel, hand wash, antibacterial soap and facial masks.
