Many people have misconceptions about the silicone oil components in skin care products, believing that silicone oil makes the skin feel heavy and causes irritation. However, high-quality silicone oil such as IOTA D5, a cyclic pentamethyldimethicone, has been proven to be a mild and safe raw material for cosmetics and personal care. With its stable physical and chemical properties, it is widely used in various personal care products. Its CAS number is 541-02-6. The component purity is high, with few impurities, and all technical indicators are strict, ensuring high safety.
From a physical and chemical perspective, IOTA D5 is a colorless and transparent liquid, with a color degree lower than 20 Hazen. It is pure and free of impurities, with a relative density of 0.95, and has a light texture that is easy to spread. The product's heavy metal content is less than 5 ppm, the closed cup flash point is 80℃, its physical and chemical properties are stable, it is non-toxic and low in irritation, and it has no irritation to the human skin or hair. Moreover, the skin absorption rate is extremely low, and it will not accumulate in the body. Sensitive skin can also be safely adapted to.
As a volatile silicone oil, the biggest feature of IOTA D5 is that it quickly evaporates after use, leaving almost no residue. This completely avoids the problems of traditional oils causing acne, stickiness, and residue formation. The industry has a clear standardized dosage: 3%-10% for antiperspirants and deodorants, 1%-5% for personal care products, and 0.5%-3% for perfumes. Within the standardized dosage range, it can not only optimize the product texture and enhance the user experience, but also ensure the product's mildness and safety, and is an indispensable high-quality functional raw material in cosmetic formulations.
