THE METAL COMPLEX OF THE COMPOUND IN (A) WHEN R1 is hydrogen; and C. THE METAL SALT OF THE COMPOUND IN (A) WHEN R1 is -COR2 or SO2R2. These derivatives are usefully employed in compositions for application to the hair, scalp or skin in order to combat the greasy and unaesthetic appearance of the hair and scalp and to counteract the formation of body odours of skin. The composition includes the said derivative of pyridine together with an appropriate carrier including, for instance, water, lower alkanol, an aqueous solution of a lower alkanol, a detergent and a cosmetic powder. The said derivative of pyridine can be included in such compositions in amounts ranging from about 0.0110 percent by weight thereof. N-oxypyridyl derivative selected from the group consisting of A.

Abstract:
A neutralizing composition to effect the second stage of neutralization of a permanent wave operation on the hair is an aqueous solution containing an N-methylol compound as an active compound in amounts of 0.5-12 percent by weight of the composition. An oxidizing agent can also be included in the composition in amounts such that the concentration of active compound and oxidizing agent is less than 1.7 moles/liter.
Abstract:
Cosmetic compositions, such as shampoos and hair dyes, which contain non-ionic surface active agents that form cleaning compositions that do not irritate the mucous membrane of the eyes having the formula IN WHICH R is selected from the group consisting of alkyl, alkenyl and alkyl and alkenyls having intervening CONH, O and CHOH groups having eight to 22 carbon atoms, and n is 1 to 5 and methods of making said compound.
Abstract:
A process and composition for dyeing keratinic fibers, particularly, human hair, in which tetrazolium salts are applied to the fibers in a colorless oxidized state and reduced to colored insoluble formazanes by reducing agents. The reducing agents are used so that the keratinic bonds are not disrupted and can be used at the same time that a permanent wave process is applied. Also, various shades can be obtained using leuco derivative dyes which become oxidized when functioning as reducing agents.
