Abstract

The invention discloses a liquid foundation containing composite modified starch and a preparation method of the liquid foundation. The liquid foundation is prepared from the following components in percentage by mass: the composite modified starch, grease, talcum powder, kaoline, allantoin, titanium dioxide, a neutralizer, an emulsifier, a thickening agent, a moisturizer, an active ingredient, triethanolamine and deionized water. The prepared liquid foundation has a good concealing effect; the stimulation of the talcum powder to skin can be effectively reduced by adding the composite modifiedstarch; spreadability, smooth feeling and smoothness of the liquid foundation are improved; the composite modified starch, as a carrier, and the active ingredient can play a combined role and have asynergetic effect; the contact area between the active ingredient and the skin is increased; the retention time of the active ingredient on the skin is prolonged; and the liquid foundation achieves abetter moisturizing and whitening effect, is not easily stacked on the skin, does not block pores easily and is easy to clear.

Description

technical field

[0001] The invention relates to the technical field of cosmetics, in particular to a liquid foundation containing complex modified starch and a preparation method thereof. Background technique

[0002] Liquid foundation is a kind of emulsion-like cosmetics added with powder. It is mainly made by taking advantage of the good compatibility of powdery materials with glycerin and water. It forms a smooth covering layer on the surface to cover or cover up some For facial blemishes, such as freckles, acne, scars, acne marks, etc., adjust the texture, color and luster of the skin, and even out the skin tone, so that the skin tone looks natural and appropriate, and it also has a smooth and tender feeling. It is easy to apply and evenly distributed. Features a natural look. Generally, liquid foundation has the characteristics of strong covering power, which can effectively cover the natural color of the skin after application, so that the skin has the color of founda...

Examples

Embodiment 1

[0052] A liquid foundation containing compound modified starch, comprising the following components in mass percentage: 3.0% compound modified starch; 6.5% oil; 6.0% talcum powder; 3.0% kaolin; 3.8% allantoin; 8.5% titanium dioxide; neutralizer 0.03%; emulsifier 1.7%; thickener 1.0%; humectant 8.0%; active ingredient 0.5%; triethanolamine 1%; 56.97% deionized water.
