Embodiment 1

[0064] Dissolve 60g of perfluorooctyltriethoxysilane (Dynasylan F8261, Evonik Degussa) and 20g of hydrogenated lecithin (LECIPLART-SOY 75H, Japan Teconobao) in 100g of ethanol to prepare a treatment solution . Under high-speed stirring, spray the treatment liquid into 1 kg of titanium dioxide, mix the treatment liquid and powder thoroughly, discharge, and bake at 110°C for 3 hours. After the material is discharged, it is jet-milled to obtain composite treated titanium dioxide.

Embodiment 2

[0066] Dissolve 60g of perfluorooctyltriethoxysilane (Dynasylan F8261, Evonik Degussa) and 20g of hydrogenated lecithin (LECIPLART-SOY 75H, Japan Teconobao) in 100g of ethanol to prepare a treatment solution . Under high-speed stirring, spray the treatment solution into 1 kg of iron oxide yellow, mix the treatment solution and powder thoroughly, and then discharge, bake at 110°C for 3 hours. After the material is discharged, it is jet-milled to obtain composite treated iron oxide yellow

Embodiment 3

[0068] Dissolve 60g of perfluorooctyltriethoxysilane (Dynasylan F8261, Evonik Degussa) and 20g of hydrogenated lecithin (LECIPLART-SOY 75H, Japan Teconobao) in 100g of ethanol to prepare a treatment solution . Under high-speed stirring, spray the treatment solution into 1 kg of iron oxide red, mix the treatment solution and powder thoroughly, discharge, and bake at 110°C for 3 hours. After the material is discharged, it is jet-milled to obtain composite treated iron oxide red.

Abstract

The invention discloses cosmetic pigment powder with water and oil repellency. The cosmetic pigment powder comprises pigment powder and a skin intimacy treating agent, wherein the skin intimacy treating agent carries out compound treatment on the surface of the pigment powder, and the skin intimacy treating agent comprises fluorine-containing silane and hydrogenated lecithin. The powder has the extremely excellent water and oil repellency, also has good pick-up property and skin intimacy, and the skin feeling is elastic, soft and smooth. According to the cosmetic pigment powder, the carbon number of the perfluor silane treating agent is smaller than or equal to 8, the perfluor silane treating agent is safe, friendly and non-toxic, and the pure plant ingredients having extremely excellent intimacy to the skin are added, so that the effects of nourishing the skin and removing the makeup easily can be achieved.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a hydrophobic and oleophobic cosmetic pigment powder and a preparation method thereof Background technique [0002] With the improvement of living standards, people's demand for cosmetics is also increasing rapidly. In the past, most cream / liquid foundations were waterproof, but rarely oil-proof. During use, the oil and sweat secreted by the skin can easily damage the makeup. According to the differences in the skin of different groups of people, it will always cause different degrees of makeup loss and makeup. [0003] In recent years, fluorine-containing silanes have also been used in a small amount in the cosmetics industry. For example, JP2008037813 and JP2008137921 disclose the use of fluorine-containing silanes in the surface treatment of cosmetic pigment powders to achieve hydrophobic and oleophobic effects. The powder feels poor on the skin, and has poor adhesion to the skin ...
