Problems solved by technology

However, these gels often fail to provide the desired degree of wash-off resistance, pigment dispersion and anti-whitening properties (anti-whitening property)
[0004] Additionally, such silicone copolymer gels have generally been manufactured by generating cross-linked silicone polymers in compounded formulations that limit the desired organofunctional groups that can be doped into the polymeric structure to yield additional performance benefits. range of regiments

[0240] Preparation method of ion-modified organosilicon crosslinked polymer

[0241] As mentioned above, provided herein is a method of preparing a personal care composition comprising an oil phase, the method comprising adding an ionically modified cross-linked silicone network gel to the oil phase of the personal care composition, wherein the ionically modified The silicone network gel is made by the following methods, including:

[0242] React the following substances:

[0243] (i) organosilicon hydrides having at least two Si-H residues,

[0244] (ii) at least one olefinic compound (siliconic or non-siliconic) having two or more unsaturated radicals,

[0245] (iii) an effective amount of a noble metal catalyst, and

[0246] (iv) an optional solvent for swelling the crosslinked silicone network; subject to the restriction that at least (i), (ii) or (iv) is selected from the group consisting of ionically modified compounds of general formula (I) described herein Silico...

Embodiment 1

[0265] 0.21 parts by weight of C-30 alpha olefin (from Chevron Phillips Company), 48.78 parts by weight of vinyl terminated with 0.062 mmol.g-1 vinyl and 0.328 mmol. Polydimethyl-co-methyl-2-methylpropylphenylsulfonate siloxane (polydimethyl-co-methyl-2-methylpropylphenylsulfonate siloxane) and 150 parts by weight of decamethylpentacyclic siloxane are placed in Ross In the mixer (mixture). The mixture was stirred and heated to 80 °C until the C-30 alpha olefin was completely dissolved. Subsequently, the mixture was cooled to 35° C., and 1.02 parts by weight of the average composition formula: (CH3 ) 3 SiO((CH 3 ) 2 SiO) 20 ((CH 3 )HSiO) 10 Si(CH 3 ) 3 A stream of indicated silanic hydrogen and 0.10 parts by weight of Karstedt's catalyst containing 2% platinum metal were stirred until a homogeneous mixture was obtained. The mixture was then stirred at 35°C for 15 minutes to promote the hydrosilylation reaction resulting in a solid crosslinked material, and mixing was c...

Embodiment 2

[0268] 35 parts by weight of the 25% solids crosslinked material described in Example 1 and 65 parts by weight of decamethylpentacyclosiloxane were blended in a Silverson mixer at 5000 rpm for 5 minutes. The obtained material was further subjected to 4 blending cycles at 5000 rpm for 5 minutes. The swollen material was then passed through a microfluidizer three times to obtain a smooth, silky cushioning gel (cushioning gel) containing -8.5% solids - viscosity 30,000 cps. The storage modulus G' of the cross-linked material is 1400Pa.

Abstract

The invention is directed to a personal care composition which contains an ionically-modified cross-linked silicone network which is formed by the polymerization of a silicone polymer containing hydrosilylation effective unsaturated moiety, silyl hydride moiety and ionic radicals.

Description

technical field [0001] The present invention relates to silicone polymers, particularly crosslinked silicone polymers, having compatibility benefits with hydrophilic components and solid particles in personal care compositions, and the resulting personal care applications (applications). Background technique [0002] The personal care industry thrives on the ability to deliver multi-performance products based on blends of multiple components, each of which has an important or desired performance characteristic in the final formulation. One desirable property is the ability to provide a silky (smooth) initial feel in the formulation. [0003] Silicone copolymer gels are well known in the personal care industry for their many uses, including use in skin care applicators. However, these gels often fail to provide the desired degree of wash-off resistance, pigment dispersion, and anti-whitening properties. [0004] Additionally, such silicone copolymer gels have generally bee...
