Particles are prepared in an emulsion using a method that includes providing a first reactant having at least two unsaturated carbon-carbon moieties and a second reactant having at least two Si—H moieties, so long as at least one of the unsaturated carbon-carbon moieties of the first reactant or the Si—H moieties of the second reactant is pendant. The method also includes providing a third reactant having a silicon atom and a condensable reactive group bonded to the silicon atom and also having an unsaturated carbon-carbon moiety and/or a Si—H moiety, providing a hydrosilylation catalyst, and providing a polar liquid. The method further includes combining the first, second, and third reactants to form particles that have a cross-linked network wherein the condensable reactive group is disposed on the particles, and adding a silane having an organic moiety and a condensation leaving group to form the particles.

Provided are an organopolysiloxane having a catechol structure per each molecule; and a powder treatment agent that is comprised of such organopolysiloxane. The organopolysiloxane is a catechol functional organopolysiloxane represented by the following formula (1):

##STR00001## wherein each R.sup.1 independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 6 carbon atoms; each R.sup.2 independently represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 6 carbon atoms, or a substituent group represented by a formula (2); a, b, c and d each represent 0 or a positive number, and satisfy a+b+c+d=2 to 1,000; in each molecule, at least one R.sup.2 is the substituent group represented by the formula (2) being expressed as:

##STR00002## wherein Y.sup.1 represents a substituted or unsubstituted divalent hydrocarbon group having 2 to 6 carbon atoms.

A composition and method is provided for synthesizing silicone particles with narrow size distributions and tunable degrees of crosslinking for encapsulation of an active ingredient or multiple active ingredients in the matrix of the particles for controlled release. The method comprises agitating at least one type of silane monomer having two, three or four siloxane bonds in an acidic aqueous solution under conditions sufficient to allow for hydrolysis of the monomers, adding a catalyst and a solution comprising a co-solvent and the active ingredient(s) to the acidic aqueous solution, and continuing to agitate the combined solution to allow for a condensation reaction and formation of silicone particles with a narrow size distribution encapsulating at least a portion of the active ingredient(s). The tunable degree of crosslink density of the particles formed is based on the ratios of the monomers used, which enables controlled release of the active ingredient(s) from the particles.
