Cosmetic Grade Hydrogenated Polyisobutene-CAS 68937-10-0
Cosmetic-grade Hydrogenated Polyisobutene is a high-purity synthetic hydrocarbon emollient, known as "synthetic squalane", which is an upgraded alternative to traditional plant squalane and mineral oil. Adopting advanced hydrogenation polymerization process, the molecular structure is saturated and stable, effectively avoiding oxidation, yellowing and peculiar smell problems of natural grease, with excellent temperature resistance and oxidation resistance.
This raw material has a unique silky and delicate skin feel, light texture, easy spreading, no sticky and greasy residue on the skin surface, and can instantly improve the dry and rough texture of the skin. It can form a uniform, thin and breathable protective film on the skin surface, lock skin moisture for a long time, reduce transepidermal water loss, effectively relieve dryness, tightness and peeling, and repair damaged skin barrier.
Compared with mineral oil, it has better affinity with human skin, no pore clogging, no acne-causing risk, mild and non-irritating. With stable physical and chemical properties, no discoloration or deterioration under high-temperature processing and long-term storage, it can be perfectly compounded with various plant oils, emollients and functional skin care ingredients. It is a core high-end emollient raw material for pursuing light, moisturizing and non-greasy skin feel in modern skin care and color cosmetics.
