Abstract
An improved permanent waving lotion is attained by incorporating into an otherwise conventional composition an organic compound having at least one function position definable as an alpha, beta-unsaturated ketone in conjunction with a carbon-carbon double bond. By employing the present invention, improved curl formation is attained and the malodor typically associated with permanently waved hair is substantially eliminated. Compounds incorporating the desired alpha, beta-unsaturated ketone can be used directly, in the permanent waving lotion, or chemical precursors can be employed to produce the desired alpha, beta-unsaturated ketone when exposed to oxidation or to alkaline materials.
