Use of the polyamino amide for the protection of the hair against the attacks atmospheric, and in particular against the application and method of protection of the hair, using such polyamino amide.

摘要

The invention relates to the use for preserve the pharmacological mechanical the hair against the degradation by the attack atmospheric and in particular by the application, of at least one of the polyamino amide generally belonging to one of the following classes: / p & & p & i. the polyamino amide (a) prepared by polycondensation of a compound acid with a polyamine chosen from among the mono- - polyalcoylenepolyamines bis - primary or secondary bis - / p & & p & the polyamino amide (a) reticules with the aid of a crosslinking agent chosen from among the epihalohydrines, the diepoxides, the dianhydrides, the anhydrides not saturated, the derivatives bis - unsaturated; / p & & p & the polyamino amide (a) alkyl reticules with an epoxide or a derivative unsaturated; / p & & p & these polymers are described in french patent n2252840. / p & & p & ii.les polyamino amide reticules, obtained by crosslinking of the polyamino amide (a) c - the top by means of a crosslinking agent, such as described in french patent no. 2368508; / p & & p & iii.les polyamino amide derivatives obtained by means of the condensation of a polyalkylene polyamine with at least one dicarboxylic acid, followed by alkylation with difunctional agents, described in french patent no. 1583363. / p & & p & iv.les polymers obtained by reaction of a poly - alkylene polyamine with a dicarboxylic acid chosen from diglycolic acid and saturated aliphatic dicarboxylic acids having 3 to 8 carbon atoms, the polyamide resultant since bring has react with the epichlorohydrin, polymers described in patents u.s. pat. no. 3227615 and 2961347.
