Section 2 | Cosmetic formulation and production process
Make-up remover oil is a product of a mixture of all oily components, used to remove oil-soluble makeup cosmetics on the skin. The main raw materials of cleansing oil are mineral oil, isopropyl palmitate and other light oils, as well as non-ionic surfactants and antioxidants. Common quality problems with cleansing oils are turbidity, precipitation, discoloration, and odor.
The production process of cleansing oil is relatively simple. The most important step is filtration to keep the product transparent.
Hair oil, also known as head oil, is mainly used to restore the gloss and softness of hair after shampooing, to prevent excessive drying of hair and scalp, and to make the hair easy to comb. Hair oil is a mixture of anhydrous oils, generally colorless or light yellow, transparent liquid. The main raw materials of hair oil are fats, antioxidants, oil-soluble colorants and nutritional additives. The common quality problems of hair oil are turbidity, discoloration and odor.
The production process of hair oil is similar to cleansing oil.
Cold ironing liquid
Cold perm is a hair cosmetic that has the effect of changing the curvature of hair and maintaining its relative stability. salt bond, and disulfide bond of the hair protein through a reducing agent, and then fix the hair into a certain shape with hairpins and curls, and then repair the disulfide bond with an oxidant, making the hair permanent. Curl. Cold liquid is generally composed of two agents. The first agent is a reducing agent. The main raw materials are mercapto-containing compounds, alkalis, surfactants, thickeners, hair conditioners, etc.; the second agent is an oxidizing agent, such as sodium bromate (potassium) ), etc.
The production process of cold iron is similar to lotion.
Semi-solid cosmetics refer to non-emulsified gel products, including skin care gel, styling gel, gel mask, etc.
skin care gel
Skin care gel, also known as skin care gel, is a transparent gel-like cosmetic. Skin care gels generally contain more moisture and can replenish and maintain skin moisture. The main raw materials are solvents (water or ethanol), gelling agents, pH adjusters, moisturizers and nutritional additives. Common quality problems of skin care gels are decreased transparency, decreased viscosity, discoloration, and so on.
In the production of skin care gels, raw materials such as gelling agents, flavors, solubilizers, and preservatives are used. The gelling agent is generally carbomer resin, which must be dispersed evenly, otherwise the expected viscosity cannot be achieved; water-insoluble substances such as fragrances and solubilizers must be dissolved in advance and added to the water, otherwise the transparency of the product will be reduced.
Styling gel is also called gel paste, hair gel, and its appearance is transparent non-flowing or semi-flowing gel. When used, apply directly to wet or dry hair to form a transparent film on the hair. After use, comb directly to form or use an electric hair dryer to assist in combing and forming. It has a certain styling and fixing effect and can also make the hair moist. ,Shiny.
The main raw materials of setting gel are water, gelling agent, setting agent, neutralizing agent, conditioning agent and so on. The ideal styling gel has a transparent appearance and stable viscosity. It is easy to apply evenly on the surface of wet or dry hair. The film formed is not sticky, making the hair easy to comb and maintain a natural and refreshing styling effect. The common quality problems of setting gels are poor transparency or white precipitation, discoloration and taste.
The production process of the setting gel is similar to the skin care gel.
Gel Mask is a cosmetic that contains nutrients and is applied to the skin of the face to form a thin film. The gel mask can cleanse the skin, maintain the skin, and beautify the skin. According to the ability to form a film after use, gel masks are generally divided into peeling masks and scrubbing masks.
The peeling mask is generally in the form of a cream or transparent gel. It is applied to the face during use. After 10 to 20 minutes of moisture evaporation, a layer of film is gradually formed. When the entire mask is removed, dirt and dander on the skin adhere to the film It was cleared. The peeling mask is easy to use and is an important one of the masks. The main raw materials of peeling mask are solvent, film forming agent, powder raw material, moisturizing agent and nutritional additives. Common quality problems of peeling off the mask are that the film-forming time is too fast or too slow, the paste becomes thick and hard, and the color and taste change. In the production process of peeling off the mask, the mixing process is very important. Improper control will cause the powdery raw materials to agglomerate and the paste is not delicate.
Scrub masks generally do not form a film, and scrub when removed after use. The characteristics of the scrub mask are that it does not contain a film-forming agent, and the main raw materials are similar to transparent gels, with viscosity modifiers, solvents, emollients, moisturizers, and nutritional additives. A large amount of powdery raw materials can also be added to the scrub mask to make an opaque gel. The common quality problem of scrubbing mask is that the paste is not delicate enough, there are impurities, and the smell has changed. The production process of scrub mask is similar to peeling mask.
