You can find polybutene in popular formulations like Pat McGrath Labs lipsticks, Tower 28 Beauty Jelly Lip Glosses, Sephora Lip Gloss, Jaclyn Hills Lip Oil, and Essence Cosmetics Lip Oil. 1-Butene is linear with a formulation of CH2=CHCH2CH3. June 1, 2022. by vigicrue aveyron villefranche de rouergue. Physicians Formula Mineral Wear Diamond Glow Lip Plumper - 1 Fl Oz - Target The large non-polar surface area created by these long carbon chains and ease of mixing being a liquid give polybutene its sought after adhesive properties. Peelable easy-to-open packaging where PB-1 is used as blend component predominantly in polyethylene to tailor peel strength and peel quality, mainly in alimentary consumer packaging and medical packaging. Polybutenes undergo combustion, pyrolysis, and autoxidation; the latter two can occur during analytical treatment. Restricted. Further, being waterproof, it makes the product last longer on the surface that it is applied on. This formula features: Enhans SC-78 #355 which allows for the incorporation of a silicone into the formula without the risk of blooming and feels silky on the skin.
