Requirements for cleaning performance are shifting from “removing dirt by any means” to “being friendly to the Earth and people.” The amino acid-based surfactants we provide are cleaning ingredients made from naturally derived fatty acids, amino acids and alkaline agents. They are characteristically able to remove a good amount of dirt while keeping hair and skin moist, in comparison with oil-, sulfuric acid- or soap-based cleaning ingredients. Furthermore, these surfactants can add different effects to products. For example, changing the combination of fatty acids, amino acids and alkaline agents can enhance foaming and enable a moist and fresh finish after cleaning.
