摘要:
Nail polish is disclosed, based upon a film-former, a resin component and a solvent system, containing as film-former and/or resin component an O-benzyl-N-hydroxyalkyl chitosan fo the formula (I)HO[C.sub.6 H.sub.11-m-q NO.sub.4 (R.sup.1).sub.m (R.sup.2).sub.n (R.sup.3).sub.q ].sub.p H (I)(with m=0 to 0.6; n=0.1 to 10; q=0.1 to 4; p=an integer from 50 to 5,000; R.sup.1 =acetyl; R.sup.2 =hydroxyethyl, 2-hydroxypropyl or 2-hydroxybutyl and R.sup.3 =benzyl).The polish film obtained with the nail polish possesses a high luster, outstanding adhesion, as well as an increased hardness compared to nail polishes based upon nitro-cellulose, with even more sufficient elasticity. Also included in the present invention are the new O-benzyl-N-hydroxyalkyl-chitosans of formula (I).

摘要:
New alkyl-hydroxypropyl-chitosans of the formula IHO[C.sub.6 H.sub.11-m-q NO.sub.4 (R.sup.1).sub.m (R.sup.2).sub.n (R.sup.3).sub.q ].sub.p H (I)(m=0-0.6; n=0.5-10; q=0.5-4; p=50-5000; R.sup.1 =acetyl; ##STR1## R.sup.3 =C.sub.1 -C.sub.6 -alkyl) and their salts with organic or inorganic acids. The invention is directed, in addition, to a process for producing the chitosan derivatives of the formula I, as well as cosmetic compositions for the treatment of hair or skin, particularly compositions for strengthening hair, comprising a content of these chitosan derivatives. The described alkyl-hydroxypropyl-chitosans are distinguished by their favorable solubility in organic solvents. Therefore, they can also be used, for example, in anhydrous hairsprays.
摘要:
Cosmetic compositions are disclosed, for the treatment of skin or hair, with a content of new N-hydroxypropyl-chitosan derivatives, composed of (a) 4 to 40 Mol-% units of Formula (I) ##STR1## and (b) 60 to 96 Mol-% units of Formula (II) ##STR2## wherein R.sup.1 and R.sup.2 are the same or different and are each hydrogen or the group ##STR3## with n being equal to an integer from 1 to 5, with the proviso that in at least 50% of the units (II), R.sup.1 and R.sup.2 are not simultaneously hydrogen, or the salts thereof; along with new N-hydroxypropyl-chitosan derivatives and their salts as well a a process for the production of these new compounds from propylene oxide and chitosan.
摘要:
A process and composition for the aftertreatment of permanently deformed hair. Often the permanent deformation leaves reducing agent or oxidant in the hair, which leads to considerable damage to the hair. Applying to the hair a composition containing glyoxylic acid and at least one organic compound having a multiple carbon-carbon bond, containing a carboxyl group bonded to the multiple bond directly or through a methylene group, which is activated by at least one multiple CO or CN bond conjugated to that multiple bond, avoids the damage caused by permanent deformation.
