In the cosmetics industry, thickeners and thixotropic agents are two common additives that play an important role in the formulation of cosmetics. Although they are all used to adjust the texture and viscosity of the product, their mechanisms of action and methods of use are very different.

let us introduce thickeners. A thickener is a chemical that increases the viscosity of a product, usually a polymer or a natural plant extract. Its main function is to make the cosmetic product easier to apply and easier to absorb on the skin surface, thereby improving the hiding power and durability of the product. Common thickeners include gelatin, hydroxyethyl cellulose, and the like, which can act like a glue in cosmetic products, making the product easier to adhere to the skin. Therefore, thickeners are often used in cosmetic products that require strong hiding power and durability, such as liquid foundations, concealers, etc. Unlike

and thickeners, thixotropic agents are mainly used to change the rheological properties of the product, making the product show different flow characteristics under different stresses. The application of thixotropic agents in cosmetics is more to increase the experience and smoothness of the product. It can make the product easier to push away during use, easier to apply evenly, and quickly become thick after use. This feature makes the product easier to apply makeup, and is less likely to cause stains and difficult to push away. A thixotropic agent is usually a high molecular polymer that changes its rheological properties under different stresses by interacting with water molecules in the product. Common thixotropic agents include dimethyl silicon-based compounds, etc., which can make the cosmetic easier to push away during use and exhibit a higher viscosity in a static state.

To sum up, although thickeners and thixotropic agents are used to adjust the texture and viscosity of cosmetic products, their mechanisms of action and application fields are very different. Thickeners are mainly used to improve the hiding power and durability of the product, while thixotropic agents are more used to improve the experience and smoothness of the product. Therefore, when choosing cosmetic products, consumers should choose the right products according to their skin type and needs to obtain a better makeup effect and a comfortable experience.
