What is Cremophor EL?
Castor oil polyoxyethylene ether is yellow viscous liquid, immune to hard water, acid, antacid and also not natural salt. Used to emulsify and also dissolve oils and other water-insoluble materials. Non-ionic solubilizer.
Castor oil polyoxyethylene ether is also called emulsifier EL-40, as well as the equivalent brand name abroad is EmulphorEL-620. It is a non-ionic surfactant. Pale yellow clear thick liquid. It is quickly soluble in water, as well as also soluble in oil, fat and also various natural solvents. The solubility in cold water is more than that in hot water, as well as it has good emulsifying residential or commercial properties for mineral oil. 1% aqueous remedy pH=6 ～ 8. The HLB worth is 13. The cloud factor of 1% liquid remedy is ≥ 85 ° C. It is resistant to acid, tough water and also inorganic salt, and additionally immune to alkali at low temperature, but strong antacids can make it hydrolyzed.
It appropriates for emulsification of different vegetable oils, mineral oils, fats, waxes, etc. It can additionally be used as a component of anti-static spinning oil for polyacrylonitrile as well as various other artificial fibers, a pesticide emulsifier, a component of wool conditioner “and hair oil”.
Cremophor EL Uses
- Polyxyl 35 Castor Oil is a triglyceride fatty acid with the prospective to push back pests and also advertise plant growth.
- Cremophor EL has been utilized as a detergent to enhance the solubility of dyes as well as boost transmembrane permeation. It has actually been made use of as a carrier for drug/stimulant distribution in cells.
- Textile industry is used as chemical fiber finishing agent, wool industry is used as blended wool oil, and vinylon antistatic spinning oil. It can also be used for emulsification of oil wax, oleic acid and mineral oil.
- Biochemical research; It is used to emulsify and dissolve oil and other water-insoluble substances. Non-ionic solubilizer. Used as solubilizer and emulsifier of water-insoluble drugs or other fat-soluble drugs in semi-solid and liquid preparations.
- Cremophor EL is utilized for solubilization of lipid-based pharmaceutical preparations and also cosmetics. Koliphor EL appropriates for the manufacturing of semi-solid and also fluid preparations of water-insoluble energetic substances as well as various other hydrophobic substances. As a result of its emulsification feature, it can be made use of for medicine transportation research study based on biofilm.

Food and preservatives
n the food industry, food-grade castor oil is used as food additive, flavoring agent, candy (for example, polyglycerol castor oil ester in chocolate), as mildew inhibitor, and for packaging. Polyoxyethylene castor oil (e.g. Koliphor EL) is also used in the food industry.
In India, Pakistan and Nepal, castor oil is used to preserve food. It can prevent rice, wheat and beans from rotting. For example, pigeonpea is usually coated with oil to prolong its storage time.
The use of castor oil as a cathartic was demonstrated in the Ebers papyrus in about 1550 BC and has been used for centuries.
Skin and hair care
Castor oil has been used in face cream and moisturizers in cosmetics. A small amount of castor oil is often used in cold soaping to increase the foam in the finished soap. It is also used to enhance the hair conditioning effect of other products, and has the so-called anti-dandruff characteristics.
Coating
Castor oil is used as bio-based polyol in polyurethane industry. The average functionality of castor oil (the hydroxyl number of each triglyceride molecule) is 2.7, so it is widely used as rigid polyol and coating. One special use is for polyurethane concrete, in which castor oil lotion reacts with isocyanate (usually polymethylene diphenyl diisocyanate), cement and construction aggregate. This is a fairly thick slurry, which is self-leveling. This base layer is usually further coated with other systems to build resilient flooring.
Castor oil is not a dry oil, which means that its reactivity with air is lower than linseed oil and tung oil. Dehydration of castor oil will produce linoleic acid with drying characteristics. In this process, the OH group on castor oleic acid and the hydrogen on the next carbon atom are removed together to form a double bond, and then have the characteristics of oxidative crosslinking to produce dry oil.
Precursors of industrial chemicals
Castor oil can react with other materials to produce other compounds with various uses. After transesterification, steam cracking is carried out to obtain undecylenoic acid, a precursor of a special polymer nylon 11, and heptaldehyde, a spice component. The decomposition of castor oil in strong alkali produces 2-octanol (a spice component and special solvent) and dicarboxylic acid sebacic acid. Hydrogenation of castor oil saturates olefins to produce waxy lubricant. Castor oil can be epoxidized by reacting OH group with epichlorohydrin to prepare castor oil triglycidyl ether which can be used in epoxy technology. This can be obtained as a commercial Heloxy 505.
The production of lithium grease consumes a large amount of castor oil. Castor oil is hydro-saponified to obtain 12-hydroxystearic acid, and then reacts with lithium hydroxide or lithium carbonate to prepare high-performance lubricating grease.
