The main functions of hydroxyethyl cellulose in cosmetics and skin care products are film-forming agents, emulsion stabilizers, adhesives, and hair conditioners. The risk factor is 1, which is relatively safe and can be used with confidence. Generally, it has no effect on pregnant women. Hydroxyethyl cellulose is not comedogenic. Hydroxyethyl cellulose is a synthetic polymer glue that is used as a skin conditioner, film former and antioxidant in cosmetics.
There are many ingredients in cosmetics, and everyone does not know what the role of these ingredients is?
The role of hydroxyethyl cellulose in cosmetics：
The solubility and viscosity properties of hydroxyethyl cellulose play a full role and maintain a balance, so that the original shape of cosmetics can be maintained in the seasons of alternating cold and hot. In addition, it has moisturizing properties and is commonly found in cosmetics for moisturizing products. Especially masks, toners, etc. are almost all added.
Can cosmetics be stored in the refrigerator?
Some cosmetics can be stored in the refrigerator, such as liquid cosmetics, and some cosmetics are not suitable for storage in the refrigerator, such as powder cosmetics or oily cosmetics.
Powder cosmetics include powder, blush and eye shadow. When storing these cosmetics, keep the cosmetics dry, because these powder cosmetics have no moisture and may absorb moisture in the refrigerator, which will cause the cosmetics to deteriorate. Store powder cosmetics at ordinary times, and store them directly in a cool, dry and ventilated place.
If the product is oil-based, it may solidify at a relatively low temperature, or cause this type of product to become viscous, so it is not suitable to store it in the refrigerator when it is stored, as long as it is stored at room temperature.
Perfume can be stored in a low temperature environment, which can increase the shelf life. Especially in summer, storing it in the refrigerator will make the perfume feel cool and comfortable when sprayed.
Some cosmetics are made of organic or preservative-free ingredients, and stored in the refrigerator can extend the shelf life and keep the cosmetics fresh.
The effect of hydroxyethyl cellulose on the skin：
Hydroxyethyl cellulose has no effect on the skin. Hydroxyethyl cellulose is used in many facial masks, facial cleansers, and shampoos, mainly because hydroxyethyl cellulose has the functions of thickener and emulsifier. Hydroxyethyl cellulose is a water-based and environmentally friendly product. Skin harmless.
Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdery solid, which is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin). Nonionic soluble cellulose ethers. Since HEC has good properties of thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloid, it has been widely used in petroleum exploration, coatings, construction, medicine, food, textile, papermaking and polymer Polymerization and other fields.
In cosmetics, the solubility and viscosity properties of hydroxyethyl cellulose play a full role, and maintain a balanced characteristic, so that the original shape of cosmetics can be maintained in the seasons of alternating cold and hot.
Hydroxyethyl cellulose product performance:
1.HEC is soluble in hot water or cold water, and does not precipitate at high temperature or boiling, so that it has a wide range of solubility and viscosity characteristics, and non-thermal gelation;
2.It is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It is an excellent colloidal thickener for solutions containing high-concentration dielectrics;
3.The water retention capacity is twice as high as that of methyl cellulose, and it has better flow regulation.
