Claims
- 1. An amide derivative represented by the following formula (1): ##STR65## wherein R.sup.1 and R.sup.2 may be the same or different and individually represent an optionally-hydroxylated hydrocarbon group having 1 to 40 carbon atoms, R.sup.3 represents a linear or branched alkylene group having 1 to 6 carbon atoms or a single bond, and R.sup.4 represents a hydrogen atom, a linear or branched alkoxyl group having 1 to 12 carbon atoms or a 2,3-dihydroxypropyloxy group, with the proviso that R.sup.4 is a hydrogen atom when R.sup.3 is a single bond.
- 2. An amide derivative according to claim 1, wherein in the formula (1), R.sup.1 is a linear or branched alkyl or alkenyl group having 8 to 26 carbon atoms, R.sup.2 is a linear or branched alkyl or alkenyl group having 9 to 25 carbon atoms, R.sup.3 is a linear alkylene group having 1 to 6 carbon atoms, and R.sup.4 is a hydrogen atom, a linear or branched alkoxyl group having 1 to 12 carbon atoms or a 2,3-dihydroxypropyloxy group.
- 3. An amide derivative according to claim 1, wherein in the formula (1), R.sup.1 is a linear or branched alkyl group having 12 to 22 carbon atoms, R.sup.2 is a linear or branched alkyl group having 11 to 21 carbon atoms, R.sup.3 is a linear alkylene group having 1 to 6 carbon atoms, and R.sup.4 is a hydrogen atom, a linear or branched alkoxyl group having 1 to 8 carbon atoms or a 2,3-dihydroxypropyloxy group.
- 4. An amide derivative according to claim 1, wherein R.sup.1 is a hexadecyl group, R.sup.2 is a tridecyl group, R.sup.3 is a trimethylene group, and R.sup.4 is a methoxy group.
- 5. An external skin care preparation comprising an amide derivative as defined in claim 1.
- 6. A cosmetic hair care formulation comprising an amide derivative as defined in claim 1.
- 7. A bath medicine comprising an amide derivative as defined in claim 1.
- 8. A skin or hair care method comprising applying to the skin or hair a preparation or formulation comprising an amide derivative as defined in claim 1.
- 9. A bathing method comprising dissolving or dispersing an amide derivative as defined in claim 1 in water and then bathing in the water.
- 10. An external skin care preparation, a cosmetic hair care formulation or a bath medicine comprising an amide derivative as defined in claim 1.
