Is polybutene harmful?
Polybutene generally is of relatively low acute toxicity. Polybutene is not irritating to the skin (Toxicity Category IV), but is irritating to the eyes and has been placed in Toxicity Category II for eye irritation effects.
What is polybutene made from?
Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene. Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.
Is Tridecyl Trimellitate safe?
Safety Measures/Side Effects: According to the EWG, this ingredient may be linked to organ system toxicity, and is classified as “Expected to be toxic or harmful” by the Environmental Canada Domestic Substance List, although no studies were found that corroborated this conclusion.
What is hydrogenated Polydecene in skin care?
Hydrogenated polydecene is a synthetic emollient and skin-softening agent. In certain formulations it lends a non-occlusive film for added skin barrier protection.
Is polyisobutene safe for skin?
The Cosmetic Ingredient Review Expert Panel determined that hydrogenated polyisobutene is safe for use in skincare and cosmetics and produces no significant adverse effects when ingested at high concentrations. They also concluded that hydrogenated polyisobutene doesn’t irritate the eyes or skin and is non-comedogenic.
