Textile friendly non-aerosol antiperspirants with a hydroxy acid

摘要

The present application relates to cosmetic antiperspirants for nonaerosol use, having a content of at least one hydroxycarboxylic acid of formula (HCS-1)
HOOC—(CHOH)n—CHOH—R  (HCS-1)wherein n represents an integer in the range from 1 to 10 and the substituent R is selected from —H and —COOH, where the hydroxycarboxylic acid can be present in free form, in salt form, or as a lactone, and where the total quantity of hydroxycarboxylic acid(s) of formula (HCS-1), optionally in salt form and/or lactone form, is 0.3 to 5 wt %, preferably 0.5 to 3 wt %, particularly preferably 1 to 2.5 wt %,which exhibit less textile staining than known antiperspirants.

主权项

1. A perspiration-inhibiting cosmetic agent for nonaerosol utilization, comprising in a cosmetically acceptable carrier
a) at least one perspiration-inhibiting aluminum salt in a total quantity from 2 to 40 wt % wherein the “wt %” of the at least one perspiration-inhibiting aluminum salt (USP) is based on the weight of the aluminum salt free of water of crystallization and free of ligands, in the perspiration-inhibiting cosmetic agent, and in addition thereto b) is 0.3 to 5 wt % of at least one hydroxycarboxylic acid of formula (HCS-1)
HOOC—(CHOH)n—CHOH—R  (HCS-1)  wherein n represents an integer in the range from 1 to 10 and the substituent R is selected from —H and —COOH, wherein the at least one hydroxycarboxylic acid of formula HCS-1 is selected from the group consisting of glucaric acid (R=—COOH and n=4), gularic acid (R=—COOH and n=4), and galactaric acid (mucic acid, R=—COOH and n=4), the salts and/or lactones of said acids, sodium gluconate, D-gluconic acid 5-lactone, and mixtures thereof, wherein the “wt %” indications refer in each case to the total weight of the perspiration-inhibiting cosmetic agent.
