Olivoil Glutamate is a vegetable derived anionic surfactant able to build dermo-compatible cleansers and rinse off products, working as a new generation “surf-active”. It is composed of active ingredients as olive oil fatty acids(containing skin friendly unsaturated fatty acids, among which oleic and linoleic acid) and glutamic acid (among the most abundant aminoacid of hair keratin and physiologically found on the skin), able to provide a gentle and effective cleansing action, skin emolliency and barrier function restoring to promote a long lasting hydration and keep the homeostasis of the hydrolipidic film, even when used in presence of sulfates/sulfonates. Ideal for hair care applications, too. Olivoil surfactants can be used both as primary and secondary surfactants and are ideal for the development of transparent end-products for sensitive skin, baby care, hair care and many other rinse-off applications, with an important impact on eco-sustainability given by their water saving features related to their rinsing off ease and the derivation from renewable sources.
