Inventory status General terms of sale

ROKAmina L30B is a very high-purity product from the betaine group, classified as an amphoteric surfactant. The commercial product is a virtually colourless aqueous solution with an active substance content of approximately 30%.

ROKAmina L30B is used as a component of cleansing preparations, especially gentle ones, used to remove impurities from the surface of the skin and hair. In combination with anionic surfactants (SLS, SLES, ABSNa), it shows a positive, synergistic increase in the foam volume and improves the stability of preparations. Furthermore, this product is stable in highly saline solutions. Thanks to these features, it contributes to reducing the use of surfactants in cosmetics and other products.
