In the high-end cosmetics industry, the luster and skin feel often determine the success or failure of a product. IOTA 21555 high-refractive index cosmetic-grade phenyl silicone oil, with the chemical name of trimethylpentyltrisiloxane, is the key ingredient that gives products a luxurious texture.
The most notable feature of this raw material is its extremely high refractive index (1.5775 - 1.5800). In cosmetic formulations, this means it can significantly enhance the brightness and glossiness of the product, making lip gloss more crystal clear and foundation liquid exhibit an advanced "water-like" texture. In addition to its optical advantages, it is also an excellent moisturizer. Its unique molecular structure gives it a rich yet non-greasy skin feel, excellent spreadability, and can effectively reduce the stickiness caused by other oils in the formula, making the applied skin feel silky smooth.
Furthermore, IOTA 21555 has excellent antioxidant properties and chemical stability, and does not require animal testing, aligning with the modern trend of green beauty. It is easy to emulsify and can be well compatible with various cosmetic ingredients, widely used in skincare, hair care, and transparent antiperspirants, helping to enhance the overall texture and efficacy of the product. It is a secret weapon for formulae to create a high-end experience for the formulationists.
