Abstract:
An aqueous emulsion comprising:(1) at least one resin, comprising at least one unit T, being: a A resin having the following formula (IV): MaDbTc(O1/2R)e(IV), â€ƒwherein: M=R1R2R3SiO1/2, D=R4R5SiO2/2, and T=R6SiO3/2, wherein R1 to R6, which are identical or different, are C1-C8 alkyl groups, R is a hydrogen atom or a C1-C4 alkyl group, a, b, and c represent the ratio of silicon atoms of type M, D and T, respectively, relative to the total number of silicon atoms in the resin of formula (IV), and e represents the number of groups â‰¡Si(O1/2R) relative to the total number of silicon atoms in the resin of formula (IV), a is between 0.1 and 0.3, b is between 0.1 and 0.5, c is between 0.4 and 0.8, e is between 0.08 and 1.5, and a+b+c=1, or a B resin having the following formula (V): DbTc(O1/2R)e(V), â€ƒwherein: D=R4R5SiO2/2, and T=R6SiO3/2, wherein R4 to R6, which are identical or different, are linear or branched C1-C8 alkyl groups, R is a hydrogen atom or a linear or branched C1-C4 alkyl group, at least 25%, on a number basis, of one or more of groups R4 to R6 are linear or branched C3-C8 alkyl groups, b, and c represent the ratio of silicon atoms of type D and T, respectively, relative to the total number of silicon atoms in the resin of formula (V), and e represents the number of groups â‰¡Si(O1/2R) relative to the total number of silicon atoms in the resin of formula (V), b is between 0.2 and 0.9 c is between 0.1 and 0.8 e is between 0.2 and 1.5, and b+c=1, (2) a product of a reaction between: (2a) ammonia or a water-soluble polyfunctional aromatic or aliphatic amine containing from 2 to 25 carbon atoms, (2b) a carboxylic acid or anhydride containing from 3 to 22 atoms, and (2c) optionally, a crosslinking agent which is a water-soluble metal, and (3) at least one surfactant selected from the group consisting of the following surfactants (a), (b) and (c): (a) nonionic surfactants, (b) anionic surfactants, and (c) amphoteric and zwitterionic surfactants selected from the group consisting of the following surfactants (i) to (iii): (i) alkyldimethylbetaines, alkylamidopropyldimethylbetaines, alkyltrimethylsulfobetaines, or products of the condensation of fatty acids and of protein hydrolysates, (ii) alkylamphoacetates or alkylamphodiacetates wherein the alkyl group contains from 6 to 20 carbon atoms, and (iii) phosphoaminolipids.
