preparation Embodiment 1

[0102] Take 494.5 g with an approximate composition of M H D. 300 D. H 4 m H The hydride liquid is mixed with 5.5 grams of vinyl cyclohexene oxide, 1500 grams of decamethylcyclopentasiloxane (D 5 ) and 0.1 gram of platinum divinyltetramethyldisiloxane catalyst solution were mixed. The resulting mixture was heated to 80°C. After 2 hours, another portion of platinum catalyst was added. The material was heated at 80°C for a total of 4 hours. In this way, a gel substance ExpMJO-07-391 with a solids content of about 26% was obtained. Then 567 grams of ExpMJO-07-391 was mixed with 1433 grams of additional D 5 mix. The resulting material was then passed through a Gaulin homogenizer twice at 4500 psi. The resulting material, ExpMJO-07-401, had a solids content of about 7.3% and a viscosity of 24,200 cps. The substance has a very silky feel when rubbed on the skin.

preparation Embodiment 2

[0104] Take 300 grams with an approximate composition of M H D. 337 D. H 11.8 m H of hydride liquid with 3.94 grams of vinylcyclohexene oxide, 37 grams of Gulgtene C30+ alpha olefin fraction (AlphaOlefin Fraction) from Chevron (hereinafter defined as substituents in the form of C30+), 1022.8 grams of decamethylcyclopentasiloxane alkane (D 5 ) and 0.1 gram of platinum divinyltetramethyldisiloxane catalyst solution were mixed. The resulting mixture was heated at 80°C for 8 hours to yield ExpMJO-07-433. The solids content of this material is approximately 25.5%. Then 587.5 grams of ExpMJO-07-433 were treated with 1412.5 grams of additional D 5 Swell and then pass through a Gaulin homogenizer at 4500 psi. The resulting material, ExpMJO-07-434, had a solids content of about 7.4% and a viscosity of 45,000 cps. It also has a very silky feel when rubbed on the skin.

preparation Embodiment 3

[0106] Take 300 grams with an approximate composition of M H 1.73 D. 388 D. H 6.9 m 0.27 hydride liquid with 3.00 g of vinylcyclohexene oxide, 9 g of Gulgtene C30+ alpha olefin fraction from Chevron, 936 g of decamethylcyclopentasiloxane (D 5 ) and 0.1 gram of platinum divinyltetramethyldisiloxane catalyst solution were mixed. The resulting mixture was heated at 80°C for 8 hours to yield ExpMJO-07-422. The solids content of this material is about 25.7%. Then 591.4 grams of ExpMJO-07-422 was treated with 1408.6 grams of additional D 5 Swell and then pass through a Gaulin homogenizer at 4500 psi. The resulting material, ExpMJO-07-437, had a solids content of about 7.26% and a viscosity of 39,000 cps.

Abstract

The present invention relates to a polyether siloxane copolymer network composition material, which is a composition material of reaction products. Said invention also provides its chemical structure formula.

Description

field of invention [0001] The present invention relates to polysiloxane compositions, and more particularly to compositions comprising a polysiloxane polymer network comprising crosslinks derived from epoxy or ethylene oxide moieties combine. Background of the invention [0002] The personal care industry thrives on multipurpose products based on blends of ingredients, each of which has performance characteristics that are important to or desired in the final formulation. One desirable attribute is the ability to provide a silky initial feel and maintain a high, shear-thinning viscosity derived from low molecular weight polysiloxanes such as octamethylcyclotetrasilane in the formulation Oxane or Decamethylcyclopentasiloxane. While these low molecular weight polysiloxanes provide desirable sensory characteristics, they are also low viscosity, high flow liquids. Therefore, they are not easily maintained in the formulation, but tend to separate or flow out of a particular co...
