Titanium-dioxide-free foundation composition and preparation method thereof

Abstract

The invention provides a titanium-dioxide-free foundation composition and a preparation method thereof. The foundation composition is prepared from the following components in parts by weight: 2.22-22.5 parts of a colorant, 11.1-45.0 parts of an emollient, 1-10.0 parts of a film-forming agent, 1-5 parts of ethylhexyl methoxycinnamate, 0.5-7.0 parts of a thickening agent, 0.1-1 part of magnesium stearate, 1.2-17.0 parts of an emulsifier, 0.1-2.0 parts of tocopherol, 1.2-25.0 parts of a skin-feeling regulator, 0.15-1.0 part of a preservative, 0.1-5.0 parts of effective active ingredients, 1-20.0part of butanediol, 0.1-3.0 part of sodium chloride and 20-50 parts of water, wherein the functional active ingredients comprise carthamus tinctorius seed oil, acmella oleracea flower / leaf / stem extract, astragalus membranaceus root extract, ubiquinone and the tocopherol. The foundation composition can present the original complexion of the skin, so that the makeup effect is natural and bright, the combined action is achieved through the modes of relaxing muscles, promoting the synthesis of collagen, enhancing the synthesis of the foundation composition, repairing a skin barrier and the like,and therefore the effect of reducing fine wrinkles of the skin is achieved within a short time. The preparation method for the titanium-dioxide-free foundation composition has the advantages of beingsimple to operate and low in cost.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a foundation composition without titanium dioxide and a preparation method thereof. Background technique [0002] Titanium dioxide is currently the colorant used in most foundation products, and it is also the raw material with the highest whiteness among cosmetic colorants. However, this feature also leads to low light transmittance due to high opacity of titanium dioxide. , so that the application of foundation products on the skin shows a pale, unnatural makeup effect. Titanium dioxide has a strong decolorization power, which affects the color rendering of other toners. When it is necessary to achieve the same color effect, it needs to be added. Larger amounts of other toners. Titanium dioxide itself has lattice defects, many photoactivation points, and is prone to chemical reactions, resulting in discoloration of the pigment. At the same time, it is prone to yellowing after absorbin...

AI Technical Summary

Problems solved by technology

The production process of titanium dioxide is mainly divided into sulfuric acid method and chlorination method. The sulfuric acid method production process includes the following steps: acidolysis of titanium slag: TiO 2 +H 2 SO 4 →TiOSO 4 +H 2 O; acid hydrolysis of ilmenite and dechloridite: FeTiO 3 +2H 2 SO 4 +5H 2 O→FeSO 4 +7H 2 O+TiOSO 4 ; Hydrolysis: TiOSO 4 +2H 2 O→TiO(OH) 2 +H 2 SO 4 ; Calcination: TiO(OH) 2 →TiO 2 +H 2 O, a large amount of waste acid is produced in the product, which greatly pollutes the environment

Due to the serious pollution of the traditional sulfuric acid process, it is not suitable for sustainable development, and some developed countries have gradually eliminated it.

However, the chlorination process with light pollution is still in use in my country, and the result is not ideal
