Have you ever wondered why some foundation liquids give off a translucent, sophisticated "water-like skin" texture when applied? Or why certain sunscreens have a light and slightly moistening feel when applied? The "black technology" ingredients behind these effects often cannot do without our current protagonist - IOTA 54 phenyl silicone oil (INCI name: DIPHENYL DIMETHICONE).
IOTA 54 is a high-end organic silicon raw material specially designed for personal care, cosmetics, and makeup. Its greatest selling point lies in its outstanding "optical properties". Its refractive index is as high as 1.50, which means it can significantly enhance the glossiness of the product. When it is added to makeup products, it can utilize the principle of light refraction to make the makeup look more seamless, natural, and three-dimensional, effortlessly getting rid of the feeling of a mask.
In addition to the glossiness, the stability of IOTA 54 is also excellent. As a colorless transparent liquid, its purity is up to 99%, and the volatility is extremely low (less than 0.5%). This means it is very "well-behaved" in the formula and will not easily evaporate or deteriorate, ensuring that the skin care products and makeup maintain their best condition throughout the shelf life.
Currently, IOTA 54 has been widely used in various skin care, makeup, and sunscreen products, with a wide range of addition ratios (0.1% - 50%). Whether you want to create a shining lip color or a moisturizing day cream, it can perfectly match and is a secret weapon for formulae to enhance product texture in the hands of formulae designers.
