Emulsifier compositions capable of forming an emulsion which is stable over a wide range of temperatures and contains at least one of a N.sup..alpha. -long-chain acyl arginine higher alkyl ester of the general formula (I) or an acid-addition salt thereof: ##STR1## wherein R.sup.1 CO is a straight-chain C.sub.8-22 acyl group; and R.sup.2 is a straight-chain or branched C.sub.12-22 alkyl group, are disclosed.

Arginine derivatives and cosmetic compositions containing the same

A process for stabilizing a specific UVB absorbing compound which comprises adding to said UVB absorbing compound at least one specific UVA absorbing compound in an amount of 0.1-10 parts by weight based on 1 part by weight of UVB absorbing compound is disclosed and also a cosmetic composition and a UV absorber, both containing said specific UVB absorbing compound and said specific UVA absorbing compound, respectively.

Method of stabilizing a UVB absorbing compound, a stabilized UV

An inorganic composition of improved characteristics comprising at least one particulate inorganic substance whose surface is modified by an N-acylated basic amino acid.

Surface modifier for inorganic substances

A detergent composition containing at least one ampholytic surface active agent of N.sup..epsilon. -long-chain-acyl-N.sup..epsilon.,N.sup..epsilon. -dimethyllysine or N.sup..epsilon. -long-chain-acyl-N.sup..alpha.,N.sup..alpha.,N.sup..alpha. -trimethyllysine or salt thereof represented by formula (I) or (II) below, and an anionic surface active agent. This detergent composition is superior in solubility, detergency, and sudsing on account of the synergistic effect of the two types of different components. This detergent composition exhibits high detergency in both soft water and hard water, and is mild to the skin and hair. ##STR1## (where RCO denotes an aliphatic acyl group of carbon number 8 to 22.).

Detergent composition comprising a mixture of an N-acyllysine and

A transparent detergent bar possessing good foaming power and detergency in hard water is formulated consisting essentially of at least one salt of a N-long chain acyl-optically active acidic amino acid neutralized with a basic amino acid in the ratio of 1 mol of the former to 1 to 2 mols of the latter and water in the range of 5 to 35% based on the weight of the bar apart from water. Other adjuvents may be present.

Transparent detergent bar

A wide variety of non-polar organic liquids are converted into gels by homogeneously admixing the non-polar organic liquids with a small amount of certain N-acyl amino acids or derivatives of N-acyl amino acids such as esters, amides and amine salts of the N-acyl amino acids.
