Abstract:
There is provided herein a low foam surfactant composition comprising: (a) di-trisiloxane alkoxylate component of the general formula (I): (R1R2R3SiO)2(R4)Si—R5—Si(R6)(OSiR7R8R9)2 (I); and, (b) mono-trisiloxane alkoxylate component of the general formula (II): (R12R13R14SiO)2Si(R15)R16 (II) wherein di-trisiloxane alkoxylate (I) is soluble in mono-trisiloxane alkoxylate and methods of making the same.
Abstract:
The present disclosures are directed to compositions comprising a polymer having branched silicone substituted by at least one alkylcarboxy group in a free or salt form and cross-linked with an alkyl functional cross-linker, which has the benefits of compatibility with hydrophilic ingredients and particulates in personal care components and the resultant personal care applications.
Abstract:
A composition for treating an aqueous fluid includes an ionic polyacrylamide and a silicon polyether. The composition can be an oil-in-water emulsion or a water-in-oil emulsion. The ionic polyacrylamide can he an anionic polyacrylamide or a cationic polyacrylamide. The composition can he employed, for example, as a friction reducing additive for water based fracturing fluid, or a drilling mud additive.
Abstract:
The present invention provides for a demulsifying composition comprising the reaction product of an oxirane or oxetane compound (I) comprising at least two oxirane or oxetane groups; a compound (II) comprising silicon and one or more amino groups; and optionally a polyamine (III); and a secondary amine (IV).
Abstract:
The present disclosures are directed to compositions comprising a polymer having linear or branched silicone substituted by at least one alkylcarboxy group and cross-linked with an alkyl functional cross-linker, which has the benefits of compatibility and structuring of personal care components and the resultant personal care applications.
Abstract:
A moisture-curable resin composition comprising (a) a moisture-curable polymer having at least one hydrolysable silyl group; (b) a reactive modifier; (c) a catalyst for catalyzing the reaction between the moisture-curable polymer (a) and reactive modifier (b) under curing conditions; and optionally, the composition can contain one or more conventional components, including pigments, fillers, curing catalysts, dyes, plasticizers, thickeners, coupling agents, extenders, volatile organic solvents, wetting agents, tackifiers, crosslinking agents, thermoplastic polymers, ultraviolet stabilizers, and combination thereof. The moisture-curable resin composition is useful in the production of adhesives including hot melt adhesives, primers, sealants and coatings.
Abstract:
The present invention is related to the preparation and use of moderately cross-linked (chin-extended), reverse (or “inverted”) surfactants, wherein the reverse surfactants comprise a polyether backbone with oligomeric or polymeric silicon-containing substitutions along the backbone. The present invention further describes crosslinked versions of the inverted surfactants, reaction products of alkenyl (allyl, vinyl, methallyl) functional copolymers (polyethers), silicone hydrides and cross-linking agents, which may be optionally reacted with water to react the remaining alkoxy groups. The crosslinking agent contains either SiH or Si-alkoxy groups or both. The compounds of the present invention exhibit only moderate cross-linking in order to be soluble or dispersible in appropriate solvents.
