Abstract
Abstract There is disclosed a formulation comprising a base component in combination with one or more organic component chosen from N-mono- and N,N-di-acylated basic amino acids, wherein the acyl group in the N-mono-acylated basic amino acid is an aliphatic acyl group having from 8 to 22 carbon atoms, and each of the acyl groups, which may be the same or different, in the N,N-di-acylated basic amino acid is an aliphatic acyl group having from 1 to 22 carbon atoms with the proviso that the two aliphatic acyl groups together have from 9 to 44 carbon atoms. The formulation is useful in novel cosmetics and as a novel surface-modified inorganic filler.
