An acylated peptide or a salt thereof obtainable by condensing a protein-derived peptide with a lanolin-derived non-hydroxyl fatty acid containing 30-45% by weight of iso-type fatty acid of the following formula (I), 30-50% by weight of anteiso-type fatty acid of the following formula (II), 10-30% by weight of normal type fatty acid of the following formula (III): CH3˜CH (CH3)—(CH2) n-COOH (n=6˜2 7) (I) CH3CH2—CH (CH3)—(CH2)n-COOH (n=6˜2 6) (II) CH3-(CH2) n-COOH (n=8˜2 8) (III) and less than 10% by weight of hydroxyl fatty acid, the total amount of said iso-type fatty acid and said anteiso-type fatty acid being at least 60% by weight; and a cosmetic composition for hair or skin containing the acylated peptide or a salt thereof; and the cosmetic composition gives excellent moist feel and gloss and the like to hair and an excellent feeling on use, such as smoothness and moistness to skin.
A cosmetic composition containing an acylated peptide or a salt thereof which is obtained by condensing a protein-derived peptide produced by hydrolysis of a protein, with a lanolin-derived non-hydroxyl fatty acid containing over 30% to 45% by weigh of iso-fatty acid of the following formula (I), 30-35% by weight of anteiso-fatty acid of the following formula (II), 10-30% by weight of normal fatty acid of the following formula (III):
An acylated peptide or a salt thereof which is obtained by condensing a protein-derived peptide produced by hydrolysis of a protein, with a lanolin-derived non-hydroxyl fatty acid containing over 30% to 45% by weight of iso-fatty acid of the following formula (I), 30-50% by weight of anteiso-fatty acid of the following formula (II), 10-30% by weight of normal fatty acid of the following formula (III):
A method of preparing an acylated peptide or a salt thereof, comprising:
