Octyl trimethicone, with a chemical formula of C39H96O7Si8 and a molecular weight of 901.86, is a unique organosilicon compound. The combination of the octyl side chain and the trisiloxane main chain in its chemical structure gives it a series of excellent chemical properties, making it widely used in the cosmetics field.
Octyl trimethicone has a high boiling point of 647.5±38.0°C, a moderate density of 0.899±0.06g/cm3, and a refractive index of 1.444. These physical properties allow it to exist stably in cosmetics, not easy to volatilize and deteriorate. At the same time, its flash point exceeds 110°C, ensuring safety during use.
In terms of chemical properties, octyl trimethicone has the characteristics of low viscosity and low surface tension. This allows it to easily spread on the skin surface to form a uniform film. This film can not only lock in moisture and prevent skin dryness, but also effectively block the invasion of external pollutants and play a role in protecting the skin.
In addition, Octyl Trimethicone also has good permeability and emollient properties. It can quickly penetrate into the deep layers of the skin and provide sufficient nutrition and moisture to the skin. At the same time, it can also combine with the oil on the surface of the skin to reduce the greasy feeling and make the skin more refreshing and comfortable.
In terms of cosmetic applications, Octyl Trimethicone is widely used as a base ingredient. In skin care products such as creams, lip balms, and sunscreens, it can provide long-lasting moisturizing effects and make the skin soft and smooth. In makeup products such as lipsticks and eye shadows, it can enhance the gloss and color intensity of the product, making the makeup more beautiful and attractive.
It is worth mentioning that Octyl Trimethicone also has excellent color powder dispersion ability. In formulas containing high volatile raw materials, it can effectively reduce white residues and improve the overall quality of the product.
In summary, octyl trimethicone plays an increasingly important role in the cosmetics field due to its unique chemical properties and broad application prospects. With the advancement of technology and the improvement of people's requirements for the quality of cosmetics, it is believed that it will have a broader market and development space in the future.
