Claims
- 1. A process for the care and protection of the skin of warm-blooded animals comprising topically applying to the skin a safe but effective amount as a moisturizing agent of a cosmetic moisturizing composition consisting essentially of an emulsion adjusted to a pH between 5 and 7 containing an emulsifier, from 1% to 20% by weight based upon the total weight of at least one aliphatic polycarboxylic acid compound of the formula ##STR3## wherein
- M is selected from the group consisting of hydrogen, alkali metal, alkaline earth metal, ammonium, loweralkylammonium and loweralkylolammonium,
- X is selected from the group consisting of hydrogen, -- COOM and --SO.sub.3 M in which M has the above-defined meanings,
- R.sub.1, r.sub.2, r.sub.3 and R.sub.4 are each selected from the group consisting of hydrogen and -- COOM in which M has the above-defined meanings, and
- m and n are each the integer 0, 1 or 2; and
- the remainder inert cosmetic excipients, said emulsion being selected from the group consisting of an oil-in-water emulsion and a water-in-oil emulsion.
- 2. The process of claim 1 wherein at least one aliphatic polycarboxylic acid compound is present in an amount of from 3% to 10% by weight.
- 3. The process of claim 1 wherein said aliphatic polycarboxylic acid compound has from three to six acid groups.
- 4. The process of claim 1 wherein M is alkali metal.
- 5. The process of claim 1 wherein M is sodium.
- 6. The process of claim 1 wherein the pH is 6.
- 7. A process for the care and protection of the skin of warm-blooded animals comprising topically applying to the skin a safe but effective amount as a moisturizing agent of a cosmetic moisturizing composition consisting essentially of a water and ethanol solution adjusted to a pH between 5 and 7 containing from 1% to 20% by weight of at least one aliphatic polycarboxylic acid compound of the formula ##STR4## wherein
- M is selected from the group consisting of hydrogen, alkali metal, alkaline earth metal, ammonium, loweralkylammonium and loweralkylolammonium,
- X is selected from the group consisting of hydrogen, -- COOM and --SO.sub.3 M in which M has the above-defined meanings,
- R.sub.1, r.sub.2, r.sub.3 and R.sub.4 are each selected from the group consisting of hydrogen and -- COOM in which M has the above-defined meanings, and
- m and n are each the integer 0, 1 or 2; and
- the remainder inert cosmetic excipients.
