	Patent 4105782: Treatment of acne and dandruff
		A composition of an.alpha.-hydroxy acid partially neutralized with ammonium hydroxide was prepared as follows: Glycolic acid, 10 ml, was dissolved in 10 ml of water and the solution admixed with 50 ml of ethanol and 10 ml of propylene glycol.
		When these acids are neutralized with metal alkalis such as sodium hydroxide or potassium hydroxide the sodium or potassium salts of.alpha.-hydroxy or.alpha.-keto acid thus formed do not penetrate human skin readily, and although the salts formed are non-irritating they are also ineffective.
		In our continued studies of topical treatment for dandruff and acne, we found that the aforementioned.alpha.-hydroxy and.alpha.-keto acids in concentrations of more than 5 percent in a solution or cream could inflame or irritate skin involved with the above skin conditions.
