摘要:Betain group-containing derivatives of carboxymethylcellulose are disclosed. They are characterized in that all or a portion of the carboxymethyl groups are or is replaced by groups of the general formula wherein R1 is hydrogen or methyl group, R2 is a divalent aliphatic hydrocarbon group with 2 to 5 carbon atoms, R3, R4 is an alkyl group with 1 to 4 carbon atoms, R5 is a divalent aliphatic hydrocarbon group with 1 to 10 carbon atoms, with the proviso that, on the average, at least 0.1 betaine groups are contained for each anhydroglucose unit of the polymeric molecule. Also, a method for the synthesis of these compounds and their use in cosmetic preparations, especially for the care of hair, are disclosed. In addition, novel derivatives of carboxymethylcellulose with tertiary amino groups are taught as intermediates. In these derivatives, all or a portion of these groups are or is replaced by groups of the general formula in which the substituents R1, R2, R3 and R4 have the above meaning, with the proviso that, on the average, at least 0.1 tertiary amino groups are contained per anhydroglucose unit of the polymeric molecule.

摘要:Eco-friendly aqueous synthesis of substantive, UV-absorbing, cationic polymers with ‘inverse temperature dependent solubility’ are described in the present invention. These polymers are water-soluble at ambient temperature and water-resistant at temperature of human body as well as in the presence of electrolytes. This property makes these polymers useful for personal care products that are designed for protecting skin and hair from damages of UV radiation. n The invention relates to aqueous synthesis of polymers of Formula I wherein, ArCO is an UV absorbing moiety selected from 2-cyano-3,3-diphenyl acryloyl, and p-methoxy cinnamoyl, R 1 is selected from H and C 1 -C 3 alkyl group, and R 2 is selected from C 1 -C 3 alkyl group, m and n are integers and a ratio of m to n is 40:5 to 40:1.

摘要:A composition and method for inducing and inflicting damage to cell membranes of microorganism by inducing changes in membrane permeability caused by polycation-induced membrane pores. The control of Clostridium difficile spores with an efficacy of 99.99% on hard surfaces is provided. The invention includes the application of an evaporation-induced self-assembly, surfactant-mediated synthesis or self-condensing polymer, which forms a film which is both flexible on the surface as a nano-polymeric coating and with refractive index yielding a transparent coating. The polymeric matrix includes various biocidal polymeric cationic quaternary salts, one being a silyl quaternary having a kinetic zeta potential to disrupt bacterial spores functions. The polymeric matrix consist of multiple small molecule biocides as well as polymerics biocide combinations not otherwise seen to develop an surface topography of peaks and troughs in the nano range to resist bacterial adhesion factors and subsequent biofilm formation. The surfactants induce self-assembly film topography.
