SEBACATES PLASTICIZERS
Sebacates plasticizers comprise of sebacates which are esters of sebacic acid. Sebacic acid is generally produced from castor oil, which is a bio based raw material. They easily adhere to other materials and can therefore be used in combination with steel, glass, metals, and other solid materials used for making inflexible plastic items. They show a high fire-resistance. Addition of certain liquid to the polymer will give a non-tacky product with a lower processing temperature and which is softer and more flexible than the polymer alone. They are flexible even at low temperatures. Their sorption properties are similar to adipate and phthalates.
Di Butyl Sebacate (DBS)
Dibutyl sebacate (DBS) is an organic chemical, a dibutyl ester of sebacic acid. These sebacates plasticizers are used in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene) and other plastics. It provides excellent compatibility with a range of plastic materials, superior properties at low temperatures, and good oil resistivit
- Di butyl Sebacate is widely used as rocket propellant.
- It is suitable for packing material in the field of food contact material, medical & pharmaceuticals.
- It is also cold resistant plasticizers for synthetic resins and synthetic rubber that posses a good resistance to cold and oil resistivity.
- It acts as an emollient, conditioning agent and solvent. Used in skin care and hair care products.
- It can be used for plastics in use in the food packaging industry, in plastics used for medical devices, and for pharmaceutical applications, e.g. as a plasticizer for film coating of tablets, beads, and granules.
- It is also used as a lubricant in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods.
Di Octyl Sebacate (DOS)
Di Octyl Sebacate (DOS) is an ester type plasticizer. It has been used for many years as a standard in polyvinyl chloride (PVC) compounds requiring flexibility at low temperatures. It is the typical high quality cold resistance PVC plasticizers with high plasticizing efficiency and low colour distortion. The most important features of DOS are low volatility; high plasticizing efficiency; excellent resistance to extraction by water, soaps and detergents; and excellent flexibility at low temperatures. These basic qualities make DOS substantially better than phthalate and adipate esters. Due to its low molecular weight and low polarity, it is deficient in terms of migration resistance and extraction by hydrocarbon fluids. It should be used in minimal amounts that meet specific low-temperature performance requirements
- DOS has favorable lubricating action when processing and is often added with phthalate to make cold resisting agricultural film, cable clad, artificial leather, outdoor water tube, and frozen food packaging film and so on.
- It can also be used in many synthetics rubber where low temperature performance is required and cold resisting plasticizer for Nitro Cellulose, Ethyl Cellulose, Polystyrene, Vinyl Chloride Copolymer and so on.
- It Acts as detackifying agent, emollient, fragrance extender, pigment wetter, dispersant, solubilizing agent, spreading agent, solvent, lubricant and plasticizer. Has a non-oily, silky skin feel and spreads easily.
- It is hydro-alcoholic compatible, can improve the spreading of oil blends, is an effective pigment wetter/dispersant and has a detackifying effect in certain compositions.
- It is used in after sun skin care, antiperspirants, beach wear sun care, aftershave lotions, daily wear sun care, eye area color cosmetics, facial color cosmetics, facial skin care, foot care, hand & body care, shaving products as well as styling aids.
