Problems solved by technology

However, a drawback to the wider acceptance and use of boron nitride (specifically, boron nitride in a predominantly graphitic crystalline form) in cosmetics and other personal care products is that it tends to be in silicone gel-containing Granular appearance and / or feel in the formulation

Embodiment l

[0285] 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):

[0286]

[0287]

[0288] Mix the silicone gel, boron nitride powder and silicone oil together at 600 rpm with an overhead mixer equipped with a cross-blade to provide a past consistency with semi-grain or flakes. ) of the silicone gel composition.

Embodiment 2

[0290] 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:

[0291]

[0292] The gel was prepared by the following method: first Silsoft TM Add 034 to Velvesil125, then add 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

[0294] Foundation compositions containing substantially the same amounts of the same ingredients (all amounts are in weight %) were prepared by sequentially mixing the ingredients indicated below at 500 rpm and 80° C. for 20 minutes:

[0295]

[0296]

[0297]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 obtained with the foundation composition of Example 4, the agglomeration was clearly visible. This difference in results can be explained by the different ways of preparing the foundation compositions. In the case of the composition of Example 3, a part of the silicone gel, all of the boron nitride supplier, and all of the silicone oil constituting the boron nitride powder-containing silicone gel of the present invention were used as a premix (implementation The silicone gel A) of Example...

Description

[0001] The application of the present invention is based on the application date of September 17, 2008, the application number is 200880116944.8 (the international application number is PCT / US2008 / 010805), and the patent application titled "organic silicon gel composition containing boron nitride" divisional application. technical field [0002] 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. Background technique [0003] 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 f...
