Abstract
Official abstract text for this publication.
The present invention provides a composition containing (A) and (B), which shows a decreased peculiar odor of acylproline and a salt thereof, has a moist feeling and is superior in the stability: (A) acylproline represented by the formula (1) or a salt thereof (wherein an acyl group represented by R 1 —CO— is an acyl group induced from saturated or unsaturated fatty acid having 3-23 carbon atoms) (B) a zinc salt of pyrrolidone carboxylate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition, comprising: (A) at least one acylproline represented by formula (1) or a salt thereof wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 3 to 23 carbon atoms; and (B) a zinc salt of pyrrolidone carboxylate. 2. The composition according to claim 1 , wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 6 to 14 carbon atoms. 3. The composition according to claim 1 , wherein (A) said acylproline represented by formula (1) is decanoylproline. 4. The composition according to claim 1 , wherein said salt of said acylproline represented by formula (1) is a sodium salt. 5. The composition according to claim 1 , wherein (A) said at least one acylproline represented by formula (1) or a salt thereof is present in an amount of 0.001 wt % to 40 wt % relative to the total weight of said composition. 6. The composition according to claim 1 , wherein (B) said zinc salt of pyrrolidone carboxylate is present in an amount of 0.01 wt % to 10 wt % relative to the total weight of said composition. 7. The composition according to claim 1 , further comprising: (C) at least one hydroxycarboxylic acid. 8. The composition according to claim 7 , wherein (C) said at least one hydroxycarboxylic acid is citric acid. 9. The composition according to claim 7 , wherein a weight ratio of (B) to (C) [(B)/(C)] is less than 1. 10. The composition according to claim 1 , which is a moisturizer. 11. A cosmetic, comprising a composition according to claim 1 . 12. A method of decreasing an odor of a composition comprising: (A) an acylproline represented by formula (1) or a salt thereof wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 3 to 23 carbon atoms, said method comprising combining in said composition: (B) a zinc salt of pyrrolidone carboxylate. 13. The method according to claim 12 , wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 6 to 14 carbon atoms. 14. The method according to claim 12 , wherein (A) said acylproline represented by formula (1) is decanoylproline. 15. The method according to claim 12 , wherein said salt of said acylproline represented by formula (1) is a sodium salt. 16. A method of suppressing production of an insoluble solid in a composition comprising: (A) at least one acylproline represented by formula (1) or a salt thereof wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 3 to 23 carbon atoms; and (B) a zinc salt of pyrrolidone carboxylate, said method comprising combining in said composition: (C) at least one hydroxycarboxylic acid. 17. The method according to claim 16 , wherein R 1 —CO— is an acyl group derived from a saturated or unsaturated fatty acid having 6 to 14 carbon atoms. 18. The method according to claim 16 , wherein (A) said acylproline represented by formula (1) is decanoylproline. 19. The method according to claim 16 , wherein said salt of said acylproline represented by formula (1) is a sodium salt. 20. The method according to claim 16 , wherein (C) said at least one hydroxycarboxylic acid is citric acid.
