Description

Facial cleanser and preparation process thereof

Technical Field

The invention relates to the technical field of daily chemical production, in particular to a facial cleanser and a preparation process thereof.

Background

The facial cleanser is also called facial cleanser, and is a high-grade face cleanser. Can clean dirt on the face and remove makeup. The facial cleanser with excellent quality has the effects of cleaning, nourishing, protecting skin and the like. In general, the general facial cleanser has no whitening effect. If a proper amount of skin whitening agent (such as arbutin, V derivatives, placenta extract, scopoletin, kojic acid and derivatives thereof, etc.) is added into the high-quality facial cleanser, the whitening effect can be achieved after long-term use.

In general, facial cleanser is a liquid product composed of oil phase material, water phase material, surfactant, humectant, nutritional agent, etc. The cream-like facial cleanser contains oil phase component, and is suitable for dry skin; the crystal clear product contains no oil phase ingredients, and can be used by most consumers if the formula is properly conditioned. The surfactant in the facial cleanser has five effects of moistening, dispersing, foaming, decontaminating and emulsifying, and is the main active substance of the facial cleanser. In addition, according to the principle of similarity and compatibility, in the process of washing face, the oil-soluble lipid dirt and redundant grease on the face can be dissolved by the oil phase; the water phase dissolves the water-soluble sweat stain on the face.

At present, although the commercially available facial cleanser has certain cleaning and makeup removing effects, the effect is relatively insufficient, and the cleansing cleanser cannot achieve a strong cleaning effect on dirt, grease and residual cosmetics in the face and pores, namely the cleansing effect on the face of a user is relatively poor. Moreover, its own function is relatively single, and it cannot play the role of skin-beautifying and skin-protecting (such as moisture-keeping, water-locking and metabolism promotion of horny layer). Based on the technical problem, the invention provides the facial cleanser and the preparation process thereof.

Disclosure of Invention

The invention aims to provide a face cleaning cream and a preparation process thereof, and the prepared face cleaning cream can effectively clean grease, dirt and residual cosmetics in the face and pores of a user and achieve the effect of combining washing and discharging.

The prepared cleaning auxiliary agent uses the active carbon with a porous structure and the chitosan porous film coated on the surface of the active carbon as base materials, so that the cleaning auxiliary agent has good adsorption performance, can effectively adsorb grease, dirt and residual cosmetics in human facial pores by mutually synergistic cooperation with the nano bamboo charcoal powder (the particle size is 100-200 nm), and has good cleaning effect on the facial parts. Meanwhile, the cleansing cream can also play a good cleansing effect, and achieves the effect of combining washing and removing.

In addition, as the surface of the matrix material is grafted with the o-hydroxybenzoic acid, the hyaluronic acid, the nicotinamide, the o-hydroxybenzoic acid and the jojoba oil can play a good role in locking water and keeping moisture for the skin under the mutual synergistic action, and can also promote the metabolism of the horny layer, thereby playing a good role in protecting and beautifying the skin.

2. The aloe extract, the jojoba oil and the cleaning factors in the aloe extract lotion are mutually synergistic, so that the aloe extract lotion has good moisturizing effect. The calendula extract can promote skin metabolism, and the oriental cherry extract can effectively act on pores, so that the oil balance of the pores is regulated, and the pores are thinner and more compact. The calendula extract, the oriental cherry extract, the cleaning factor and the nano bamboo charcoal powder are mutually cooperated and matched, so that the facial cleanser can effectively clean the face of a human body, remove grease, dirt and residual cosmetics in pores of the human body and play a certain positive role in removing makeup.
