Foundation cream with tiramisu apparent condition and preparation method thereof

Abstract

The invention discloses a foundation cream with a tiramisu apparent condition and a preparation method thereof. The preparation method comprises the step of preparation of a foundation premix, namely carrying out composite surface treatment on titanium dioxide and ferric oxide inorganic powder by adopting two polysiloxane surface treating agents, namely methylhydrosiloxane and hydroxyl polydimethylsiloxane, with two active groups to obtain the foundation premix for preparing the foundation cream with the tiramisu apparent condition, wherein the composite ratio of the methylhydrosiloxane to the hydroxyl polydimethylsiloxane is (1:10) to (10:1); and the surface treating agent accounts for 1-2wt% of mass percent of inorganic powder. The prepared foundation cream with the tiramisu apparent condition is in a W / Si dosage form, and has a bran-new touch effect while providing a novel and unique appearance, and is light in skin feeling, good in water resistance and not easy to fall off.

Description

technical field [0001] The invention relates to the field of daily cosmetics, in particular to a foundation with the appearance of tiramisu and a preparation method thereof. Background technique [0002] Foundation cream / liquid is a very important cosmetic category, and it is also the basis for a good makeup effect. Cosmetics manufacturers usually provide foundations of different colors (such as dark skin and light skin) etc. according to the user's skin color. Ordinary foundation cream looks like a cream or lotion with a uniform texture. [0003] In order to create novel visual and tactile effects and achieve the purpose of attracting consumers, solid or semi-solid appearance dosage forms such as gel foundation, jelly foundation, and yogurt cream have appeared in recent years. These new formulations of cosmetics can not only play the role of ordinary foundation to cover fine wrinkles or blemishes on the skin, but also have a special appearance and a novel sense of use.

AI Technical Summary

Problems solved by technology

[0014] ①Since only oil-in-water (O / W) formulas can be used, the added inorganic powders (such as titanium dioxide, iron oxides) are limited to water-dispersed types, and the formulas have poor water resistance. Sweating and oily make-up take off and fade

[0015] ②The melting point of coagulants such as agar is very high, so a high-temperature hot-mixing process must be used, which requires high energy consumption and manufacturing costs

[0017] 2. Defects of Carbo-type oil-in-water (O / W) gel foundation

[0019] ①Same as the coagulation type, the formula has poor water resistance

[0020] ②Carbopol is sensitive to acid, so acidic ingredients cannot be added to the formula, otherwise the gel state will be destroyed, but many active substance additives are slightly acidic, and the application of these active substances will be limited

[0021] 3. Defects of shear-thinning oil-in-water (O / W) gel foundation

[0022] The dosage form can only be oil-in-water (O / W) type, and the addition of a large amount of hydrophilic colloids will easily affect the skin feel

[0023] ①Same as the coagulation type, the formula has poor water resistance

[0024] ② Hydrophilic colloids such as xanthan gum need to be added to a certain amount to make the foundation reach a gel state, and excessive addition of hydrophilic colloids will easily cause sticky skin feeling
