Polybutene is generally water-white, reaching less than 50 on APHA color scale. (typically less than 10) The product remains very stable after being prolonged exposure to UV light. Polybutene is more stable than conventional mineral oil with same APHA color.
Polybutene is a non-polar hydrocarbon polymer hence it has high solubility in aliphatic, aromatic and chlorinated solvents. It is compatible with a wide variety of organic materials, for instance, synthetic hydrocarboon polymers including wax, rosin, asphalt and gum.
Polybutene is safe to use, because it is non-toxic. Polybutene is allowed by the FDA for a wide variety of applications as components of articles.

??? ??

Polybutenes are light colored, nondrying, sticky, viscous liquids. They are stable when exposed to light, insoluble in water, and soluble in hydrocarbon and chlorinated hydrocarbon solvents. Polybutene-1 has a density of 0.92g/cm3 and a melting range of 124°C-130°C.
Polybutene is available in a variety of grades. The differences depend on viscosity, which increases directly in proportion to increasing molecular weight.
Polybutene films have a high resistance to stress cracking, and low stress deformation.

??

polybutene is a binder and viscosity-increasing agent used more in makeup than skin care preparations. Polybutene is a polymer of one or more butylenes obtained from petroleum oils.

?? ??

Fuel and lubricant additives – Fuel dispersants, lubricant dispersants
Adhesives
Caulk and sealants
Gum base
Wrap film
Lubricants – Two-stroke engine oil, lubricant for rolling wire drawing, compressor oil and viscosity index improvers (VIIs)
Electrical insulation
Others – Asphalt modifier, resin plasticiser, rubber modifier and dispersing agents

Passman describes an industrial preparation of Polybutene in which a solution of 1-butene is dried and fed into a reaction chamber. A Zeigler-Natta reagent (TiCI3, and diethyl aluminum chloride) is added to catalyze the polymerization process. The molecular weight of the end product is limited by the reaction temperature used in the chamber.

Recommended Personal Protective Equipment: Goggles or face shield; Symptoms Following Exposure: Low toxicity. Vapor may act as a simple asphyxiant in high concentrations; General Treatment for Exposure: INHALATION: remove victim from exposure; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Term Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 0, LD50 > 15 g/kg; Late Toxicity: None; Vapor (Gas) Irritant Characteristics: Vapors are nonirritating to the eyes and throat; Liquid or Solid Irritant Characteristics: No appreciable hazard. Practically harmless to the skin; Odor Threshold: Data not available.

?? ??

Polybutenes undergo combustion, pyrolysis, and autoxidation; the latter two can occur during analytical treatment. Their low polarity, low degree of unsaturation, and their closely packed, branched-chain molecular structure make Polybutenes resistant to chemical reaction.
