Abstract: A method for regulating hair growth is provided which comprises administering, to a subject in need thereof, dodecylcarbomoylmethyltrimethylammonium chloride and/or a compound of salt thereof selected from 2-dimethylamino-N-ethyl-acetamide, 2-dimethylamino-N-(2-{2-[2-(2-dimethylamino-acetylamino)-ethoxy]-ethoxy}-ethyl)-acetamide, 2-dimethylamino-N-[8-(2-dimethylamino-acetylamino)-octyl]-acetamide, 2-dimethylamino-N-[2-(2-{2-[2-(2-dimethylamino-acetylamino)-ethoxy]-ethoxy}-ethoxy)-ethyl]-acetamide, 2-dimethylamino-N-[12-(2-dimethylamino-acetylamino)-dodecyl]-acetamide, and 2-dimethylamino-N-[4-(2-dimethylamino-acetamino)-butyl]acetamide.

Abstract: A hair growth regulating agent containing, as an active ingredient, a compound represented by the following formula (I): [wherein R1 represents a substituted or unsubstituted, linear or branched C2 to C25 alkyl group; a group represented by the following formula (II): (wherein R1? represents a substituted or unsubstituted, linear or branched C2 to C20 alkylene group, or —(CH2)n-{O—(CH2)m}o-O—(CH2)p- in which each of n, m, o, and p is an integer from 1 to 6; X? represents —CO—NH—, —O—CO—O—, —NH—CO—, —CO—O—, —O—CO—, or —O—; Y? represents a substituted or unsubstituted C1 to C4 alkylene group; R2? represents a hydrogen atom or a C1 to C4 alkyl group; R3? represents a C1 to C4 alkyl group; and when R2? and R3? each represent a C1 to C4 alkyl group, the two alkyl groups may be identical to or different from each other); or a group represented by the following formula (III): (wherein R1?, X?, and Y? have the same meanings as defined above; R4?, R5?, and R6?, which may be identical to or different from one another,

Abstract: An elastase inhibitor containing, as an active ingredient, a protein hydrolysate (with soybean protein hydrolysate and almond protein hydrolysate being excluded). Pharmaceuticals and cosmetics containing such an elastase inhibitor which exhibit an inhibitory effect against the growth of body hair, and skin aging preventing effect by restoring elasticity and tonicity of the skin and reducing wrinkles.
