If its being used as a rich emollient in a skincare product, I thinkLanolin, Brassica Campestris Aleurites Fordi Oil Copolymer, orLecithinmight work as an alternative. Although industrial applications are found in boosting properties such as adhesion, anti-rust and water repellency in coatings, polybutene is also often used in cosmetics such as lipstick formulations. A polybutylene terephthalate resin composition is disclosed containing, with respect to 100 parts by mass of a polybutylene terephthalate resin (A) having a carboxylic acid terminal group of 35 meq/kg or less, 0.5 parts by mass or more and 10 parts by mass or less of an epoxy-based resin (B), and a quaternary ammonium salt (C); a molded article comprising the polybutylene terephthalate resin . Polybutene mixes well with Hydrogenated Polyisobutene, liquid oils, and esters. The compound can furthermore improve the viscosity index of mineral oils. It has similar properties and composition to polyethylene terephthalate (PET). Polybutenes undergo combustion, pyrolysis, and autoxidation; the latter two can occur during analytical treatment. Polybutene is similar to polyisobutylene (PIB), but the two compounds differ in certain regards. Fittings with a soft compression seal can give adequate service life. In extreme cases, this stress-activated chemical "corrosion" can lead to perforation and leakage within a few years, but it also may not fail for decades. Also, acute dermal irritation testing indicated that polybutenes are practically nontoxic because the LDso is greater than 10, 250 mg/kg.

Other applications include domestic water heaters, electrical insulation, compression packaging, wire and cable, shoe soles, and polyolefin modification (thermal bonding, enhancing softness and flexibility of rigid compounds, increasing temperature resistance and compression set of soft compounds). However, polybutenes are highly flammable and have poor weather resistance without additional stabilization. It is also used synergistically as a blend element to modify the characteristics of other polyolefins like polypropylene and polyethylene. For our customers, this means certainty in every regard: from compliance with statutory requirements, to product specifications, to prompt and punctual delivery.
