Description

Skin-adhering moisturizing foundation cream and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a foundation cream for moisturizing skin and a preparation method thereof.

Background

Foundation creams are the basis of makeup, and powder foundations are the most common, and are soft and natural when applied to the face, so that the foundation creams are the best choice for daily makeup. When makeup is carried out, people always forget to make a layer of foundation cream. Therefore, the foundation cream is a foundation for women's makeup and is better than foundation cream to some extent, and the skin care is more delicate and soft. The qualified foundation cream generally needs to have the effects of concealing flaws, preserving moisture and replenishing water, being smooth and fine, being naturally attached, being glittering and translucent and the like. In order to achieve the effects, the traditional foundation cream is prepared by adopting mineral components and chemical synthesis raw materials such as talcum powder, mineral oil, alcohol, ring-shaped silicon D5, nipagin ester and the like; the addition of the substances can cause unnecessary irritation, even damage and allergy to the skin. Especially people with special skin, such as people with allergic constitution.

The Chinese patent CN108324677B discloses a foundation cream suitable for people with sensitive skin, which is prepared by mixing the following components in percentage by weight: caprylic/capric triglyceride 6.5-7.5%, mica powder 3.0-5.0%, tridecyl alcohol trimellitate 6.2-7.2%, distearyl dimethyl ammonium hectorite 0.5-0.7%, isododecane 11.0-13.0%, sorbitan sesquioleate 1.3-1.9%, polyglycerol diisostearate 1.4-1.8%, stearyl polyether-21.4-1.8%, beeswax 0.4-0.6%, coconut oil 1.94-3.88%, Gardenia jasminoides extract 0.04-0.08%, vitamin E0.08-0.1%, deionized water 40-48%, disodium edetate 0.08-0.1%, dipotassium glycyrrhizinate 0.1-0.11%, 1, 3-butanediol 4.0-4.4%, propylene glycol 3.5-4.5%, Bacillus fermentation product 0.001-0.002%, hexanediol 0.05-0.06%, 9.5 to 10.0 percent of colorant; the sum of the above components is 100%. The patent endows the product with fresh and non-greasy characteristics through a natural plant-derived pigment dispersing agent; the plant extract and the biological fermentation product are compounded, so that the product has the effects of preventing the skin from drying and cracking, further recovering and maintaining the natural elasticity of the skin, and also has the effects of diminishing inflammation, assisting in anti-allergy and combining color cosmetics and skin care, thereby realizing the effect that the product is suitable for sensitive skin and meeting the requirements of sensitive skin consumers on cosmetic products. With the development of science and technology, natural, safe and environment-friendly products are sought to meet the requirements of consumers on safe products, so that the cosmetic market prospect is wider. Based on the statement, the invention provides the foundation cream which is attached to the skin and used for moisturizing and the preparation method thereof.
