    Abstract: One of the purposes of the present invention is to provide an emulsion composition which has a small initial diameter and good stability with time and dilution stability. Further, another purpose of the present invention is to provide an emulsion composition which has high adsorption ability to fibers and provides a hydrophilic surface of the fibers. Thus, the present invention is an emulsion composition comprising water and an aminoalkyl group and polyoxyalkylene group-containing siloxane represented by the following general formula (1): (R13SiO1/2)k(R12SiO2/2)p(R11SiO3/2)q(SiO4/2)r (1) wherein R1 is, independently of each other, a hydroxyl group, an alkoxyl group, a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, or a group represented by the following formula (2), (3) or (6): —(CR2H)a—(NHCH2CH2)b—NH2 (2), —(CR2H)c—O—(C2H4O)d—(C3H6O)e—R3 (3), —(CR2H)f—(R52SiO)s—SiR53 (6); provided that at least one of R1 is the group represented by the formula (2) and at least one of R1 is a group represented by the formula (3).

    Abstract: A method of preparing condensation cross-linked particles in an emulsion includes combining a first linear reactant having two unsaturated carbon-carbon moieties, a second linear reactant having two Si—H moieties, and a third reactant having at least one condensable reactive group and having up to two unsaturated carbon-carbon moieties or Si—H moieties with the proviso that the third reactant has at least one unsaturated carbon-carbon moiety or S—H moiety. The first, second, and third reactants are combined in the presence of a hydrosilylation catalyst and a polar liquid to form an emulsion wherein the first, second, and third reactants react via a hydrosilylation reaction to form particles that have a linear backbone wherein the condensable reactive group is disposed thereon. The method also includes cross-linking the linear backbone via a condensation reaction to form the condensation cross-linked particles.
