Embodiment 1

[0218] A stable boron nitride powder-containing silicone gel composition (Silicone Gel A) was prepared according to the invention by combining the following ingredients (all from Momentive Performance Materials):

[0219] Element describe weight, g Wt.%

[0220] Velvesil 125 (in cyclopentasiloxane 48.72 69.60

[0221] Cross-linked C30-45 alkanes for silicone gels

[0222] Hexadecyl / octadecyl

[0223] Polydimethylsiloxane

[0224] (crosslinked

[0225] C30-45 alkyl

[0226] cetearyl

[0227] dimethicone))

[0228] Softouch TM Boron nitride powder 12.18 17.40

[0229] CC6097

[0230] Silsoft TM Silicone oil (octyl polymethyl 9.10 13.00

[0231] 034 silicone)

[0232] 70.00g 100.00%

[0233] Mix the silicone gel, boron nitride powder and silicone oil together at 600 rpm with an ...

Embodiment 2

[0235] Using the same ingredients as in Example 1, another stable boron nitride powder-containing silicone gel composition (silicone gel B) was prepared according to the present invention. The amounts of the various ingredients in the gel are as follows:

[0236] Element weight, g

[0237] Velvesil 125 69.6

[0238] silicone gel

[0239] Softouch TM 17.4

[0240] CC6097

[0241] Silsoft TM 13.0

[0242] 034

[0243] 100.0g

[0244] The gel was prepared by the following method: first Silsoft TM 034 added to Velvesil 125, then Softouch TM CC6097 while stirring at 100 g for 15 minutes at ambient temperature using an overhead mixer fitted with a 3-blade impeller.

Embodiment 3 and 4

[0246] Foundation compositions containing substantially the same amounts of the same ingredients (all amounts are in % by weight) were prepared by sequentially mixing the ingredients indicated below at 500 rpm and 80° C. for 20 minutes:

[0247] Element Example 3 Example 4

[0248] Velvesil 125 29.89 40.20

[0249] Polysilsesquioxane 10.62 10.62

[0250] Cyclopentasiloxane 36.63 36.63

[0251] Phenylpropyldimethyl-silyloxysilicic acid 2.71 2.71

[0252] Esters (Penylproplydimethyl-siloxy silicate)

[0253] C30-45 Alkyl Dimethicone 5.33 5.33

[0254] Silsoft TM 034 ----- 1.92

[0255] Silicone gel A (from Example 1) 14.82 -----

[0256] Softouch TM CC6097 ----- 2.58

[0257] 100.00 99.99

[0258]Each foundation composition was applied to Lenetta paper and drawn down to provide a 5 mil thick film. The film obtained with the foundation composition of Example 3 showed no visible agglomeration, whereas in the case of the film ob...

Description

Background technique [0001] The present invention relates to silicone-based compositions, and more particularly, to stable boron nitride-containing silicone gel compositions useful in the formulation of personal care products and the like. [0002] Silicones have been used for many years in a variety of industrial applications such as the electronics industry, agriculture, home and household care and personal care products and a host of other applications. Although many of these products are in liquid form, silicone gels have gained increasing popularity, for example due to their ability to improve the sensory properties (mainly touch and feel) of cosmetics and other kinds of personal care products. commercial importance. Silicone gels provide formulators of personal care products with enhanced functionality, for example, the ability to increase the effectiveness of trisiloxanes and alkyltrisiloxanes in the spreading of cosmetic compositions containing the materials.
