化學油脂也有對皮膚威脅小的。像是不具極性的凡士林、礦物油、氫化聚異丁烯、高級烷類、高級烯類等，因為與皮脂相容性差、也不具溶劑效應，自然的對皮膚的可能副作用傷害就比較小。

【Hydrogenated Polyisobutene】

Rating: GOOD
Benefits: Hydration
Categories: Emollient, Texture Enhancer, Polymer

Hydrogenated polyisobutene is a synthetic, relatively viscous emollient with research backing its ability to provide long-lasting moisture retention. It acts as a lubricant on skin’s surface, providing a soft, smooth feel.

In some formulas, hydrogenated polyisobutene is used as a substitute for mineral oil or silicones because of its similar action to help maintain skin’s moisture barrier and improve the feel of skin care products.

The independent Cosmetic Ingredient Review Board found hydrogenated polyisobutene is safe as used in cosmetics, where it is generally found in amounts of 4% or less.
