Sodium PCA 50%

Sodium PCA 50% is a humectant based on an amino acid that binds water in the skin and hair and retains it even in dry environments. The sodium salt of pyrrolidone carboxylic acid is a natural component of the NMF , the natural moisturising factor of human skin. It thus supplements a substance that the stratum corneum naturally contains. It is produced from L-glutamic acid and is supplied as a 50% aqueous solution with ECOCERT certification. It is added to formulations in low percentages, into the water phase or into the finished emulsion during cooling. It suits moisturising creams, tonics and serums, as well as shower gels, shampoos and conditioners, where it reduces the feeling of skin tightness after washing. Key benefits Hydration – as a humectant it attracts water and holds it in the surface layers of the skin. According to the manufacturer's measurements, it can absorb water up to 70% of its dry weight and retains it even at low air humidity. Skin-native ingredient – PCA forms approximately 12% of the natural moisturising factor according to the manufacturer's data. Suitable for dry, sensitive and oily skin. Elasticity and skin barrier support – an adequately hydrated stratum corneum acts more supple and smooth.

In shower gels and cleansers it therefore reduces the drying sensation after washing. Hair manageability – according to the manufacturer's tests, shampoos and conditioners with Sodium PCA impro
