Abstract
Abstract Staining in the underarm areas of garments due to the presence of perspiration and the residue of an aluminum salt containing anti-perspirant is preventable by incorporating into the anti-perspirant composition specific water soluble mild reducing agents including various sulfur or phosphorus compounds or stannous or titanous salts. Alternatively, the reducing agents rather than being incorporated into the anti-perspirant composition may be employed to treat the soiled garments prior to washing or dry cleaning the garments.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
250 words
In an anti-perspirant composition containing as the active ingredient an astringent aluminum salt and a dermatologically-acceptable vehicle, the improvement wherein the composition comprises a cosmetically-acceptable reducing agent in an amount of about 0.01 to 10 percent by weight, based on the total weight of the composition, and sufficient to inhibit staining of fabric in contact with the composition and with perspiration, the reducing agent being water dispersible, essentially odorless, non-irritating to skin and a member selected from the group consisting of: a. ammonium sulfite, alkali-metal sulfite, alkaline-earth-metal sulfite, zinc sulfite or a mixture thereof; b. ammonium bisulfite, alkali-metal bisulfite, alkaline-earth-metal bisulfite or a mixture thereof; c. sodium dithionate, zinc dithionate or a mixture; d. alkali-metal meta-bisulfite; e. alkali-metal thiosulfate, alkaline-earth-metal thiosulfate or a mixture thereof; f. 2-thiobarbituric acid mono-substituted-2-thiobarbituric acid in which a substituent is in the 2- or the 5-position, disubstituted-2-thiobarbituric acid in which each substituent is in one of the 2- and 5-positions or a mixture thereof; g. 2-pyridinethione; h. alkylamine bisulfite; i. sodium formaldehyde bisulfite; j. sodium formaldehyde sulfoxylate, zinc formaldehyde sulfoxylate or a mixture thereof; k. acetone sodium bisulfite; l. cysteine, homocysteine, N-acetyl cysteine, N-acetyl homocysteine, homocysteine thiolactone, S-cysteine sulfonate sodium, cysteine-S-phosphate sodium or a mixture thereof; m. penicillamine; n. thiomalic acid; o. thiosalicylic acid; p. 2-mercaptoethylamine hydrochloride; q. dithiothreitol; r. thiourea dioxide; s. thiazolidine-2-carboxylic acid; t. ammonium hypophosphite, alkali-metal hypophosphite, alkaline-earth-metal hypophosphite or a mixture thereof; u. ammonium phosphite, alkali-metal phosphite, alkaline-earth-metal phosphite or a mixture thereof; v. tetrakis(hydroxymethyl)phosphonium chloride; and w. dermatologically-acceptable stannous salt.
