Castor oil is a triglyceride of fatty acids. Castor oil is found in castor beans In the seeds, its content is 35% to 57.%. “Castor oil is obtained by squeezing or solvent extraction. It is almost colorless or slightly yellow, clear and viscous liquid; has a slight odor; has a light taste and then is slightly pungent, and is easily soluble in ethanol. , can be mixed with absolute ethanol, chloroform, ether or glacial acetic acid.
SupplyShanghai of castor oil pointed out:Castor oil and some of its derivatives are excellent cosmetic raw materials. The specific advantages and functions are as follows:
1. Moisturizing properties:
Castor oil is basically composed of triricinoleic acid glyceride. Compared with other oils, the uniformity of this molecular structure makes its melting range and viscosity range smaller than other oils. Grease. The unsaturation and structural uniformity of castor oil lead to its low pour point (23°C); the monounsaturation lowers the melting point by more than 100 degrees; the hydroxyl groups in castor oil and some of its derivatives can form hydrogen bonds It has high viscosity, which makes the cosmetics feel comfortable on the skin and maintains good moisturization.
2. Strong antioxidant ability:
p>
Castor oil and some of its derivatives are very stable due to the removal of hydroxyl groups at the beta position of the double construction and will not cause rancidity. Olive oil is the most stable vegetable oil except castor oil, but The stability of castor oil is about four times that of olive oil.
3. Mild and non-irritating:
Use products with acne genes Cosmetics and cosmetic ingredients can aggravate or cause acne, thus becoming a growing concern for dermatologists and consumers. Castor oil and its derivatives have an almost uniform long fatty acid carbon chain and a unique chemical structure. Its performance is mild and does not irritate the skin.
4. Good co-solubility and pigment wettability:
Cosmetics are often made of a variety of properties Different raw materials are mixed under certain conditions, which requires good compatibility between the components. The hydroxyl groups on the long fatty acid carbon chains of castor oil and some of its derivatives promote good co-solubility with other components and pigments. Moisturizing properties, thus ensuring even mixing of cosmetics.
