General Description
3-Ethyl-1,1,1,5,5,5-hexamethyl-3-trimethylsilanyloxy-trisiloxane is a type of chemical compound that belongs to the trisiloxane family. Trisiloxanes are a class of silicone-based compounds that have a wide range of industrial applications, including as surfactants, foam stabilizers, and anti-foaming agents. This specific compound contains a unique molecular structure with three silicon atoms, six methyl groups, and one ethyl group. It is also characterized by the presence of trimethylsilane and trimethylsiloxane functional groups. 3-Ethyl-1,1,1,5,5,5-hexamethyl-3-trimethylsilanyloxy-trisiloxane is commonly used as a surface modifier in coatings, adhesives, and sealants, as well as in the formulation of personal care and cosmetic products. Additionally, its properties make it suitable for use as a lubricant and in the manufacturing of specialty chemical products.
Check Digit Verification of cas no
The CAS Registry Mumber 18030-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,3 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18030-66:
(7*1)+(6*8)+(5*0)+(4*3)+(3*0)+(2*6)+(1*6)=85
85 % 10 = 5
So 18030-66-5 is a valid CAS Registry Number.

, (2008/06/13)
The invention relates to a composition comprising, in a physiologically acceptable medium, a volatile silicone fatty phase comprising at least one non-cyclic volatile silicone oil, wherein the volatile silicone fatty phase has an evaporation profile such that the mass of the at least one volatile silicone oil evaporated after 30 minutes is from 2 mg/cm2 to 9 mg/cm2. The invention also relates to making up and caring for human keratin materials using the inventive compositions.
Treatment of alkyltriethoxysilanes with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane

Methyltriethoxysilane and ethyltriethoxysilane were treated with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane at 40 deg C.The reaction involves partial or full replacement of the ethoxyl group by trimethylsiloxyl to give RSi(OEt)n(OSiMe3)3-n (n=0, 1, 2).The degree of substitution depends mainly on the ratio in which hexamethyldisiloxane and alkyltriethoxysilane are mixed.The nature of alkyl group in an alkyltriethoxysilane had little effect on the degree of substitution at a given mixing ratio.
