What are the functions of hydrogenated castor oil in cosmetics?
Hydrogenated castor oil manufacturer introduces the role of hydrogenated castor oil in cosmetics:
Hydrogenated castor oil is a modified castor oil product that is easily decomposed and leaves no residue. Modified castor oil products are easy to decompose in nature and will not have any residue. The product functions may vary slightly depending on the different epoxides used (PEG-40, PEG-60, PEG-80).
With the changing demand in the cosmetics consumer market, cosmetic materials are being updated and upgraded. Consumers' requirements for skincare products are not only for cleaning and moisturizing functions, but also for wrinkle removal and enhanced skin elasticity. The selection of cosmetic materials directly affects the hygiene and safety of cosmetics. Therefore, China, along with most developed countries and regions such as the United States, Japan, and the European Union, adopt strict processing methods for cosmetic materials.
Licorice extract has been proven to be the most effective plant whitening agent, but due to the low content of active ingredients in licorice and the difficulty of purification, it is one of the most valuable cosmetic materials. Wool ester has the functions of softening the skin, avoiding defatting, and preventing skin cracking. It can be compatible with various materials and is a good cosmetic material.
Hydrogenated castor oil polyoxyethylene ether can be used as an emulsifier, wetting agent, solubilizer, and fatliquor in cosmetics, with functions such as moisturizing, anti-inflammatory, anti allergic, repairing skin barriers, and reducing melanin deposition.
Specifically, hydrogenated castor oil polyoxyethylene ether has good hydrophilicity and can form a protective film on the surface of the skin, reducing skin moisture loss, replenishing the necessary moisture for the skin, and achieving moisturizing effects. In addition, it also has anti-inflammatory and anti allergic effects, which can alleviate skin inflammation and itching symptoms, repair damaged skin barriers, and have certain antioxidant effects, reducing melanin deposition and achieving the effect of whitening the skin.
Castor oil polyoxyethylene ether has various uses in cosmetics, including:
Emulsifier: castor oil polyoxyethylene ether has a strong emulsifying ability, which is particularly suitable for creating a makeup remover formula that can be washed and cleaned in one wash, and can form a stable oil-water lotion without the need for secondary washing2.
Thickener: By adjusting the amount of ethylene oxide added, the viscosity of the product can be precisely controlled, such as achieving a rheological property of 1200cP for shower gel at 25 ℃, balancing smoothness and washability.
Foaming agent: maintain a stable foam structure within the range of pH5.5-7.5, with a foaming index of 8.2 (full score of 10), and a 40% increase in the fineness of foam, suitable for people with sensitive muscles.
Moisturizing agent: The hydrophilic groups of polyoxyethylene chains can form a molecular film of 3-5nm. Experiments have shown that continuous use of skincare products containing CETE-20 for 4 weeks can increase the moisture content of the skin's stratum corneum by 28% and prolong the effectiveness time to 12 hours.
Antioxidant: after adding 0.1% vitamin E, the shelf life of the product is extended from 6 months to 18 months, and the antioxidant activity is 3 times higher than that of ordinary antioxidants. It is suitable for developing sunscreen, essence and other categories that need long-term storage.
PH stabilizer: Within the pH range of 0.5-10, the surface tension fluctuation is only ± 0.15mN/m, suitable for multiple formulation systems, and the foaming performance in hard water environments does not decrease by more than 15%.
In addition, castor oil polyoxyethylene ether has also passed ISO14001 environmental management system certification, with a biodegradation rate of 92% within 28 days, meeting the EU EC1223/2009 biodegradation standard and suitable for developing green certified products. In the cosmetics formula, it can be used for shampoo, essence and other products, providing foam density, lasting oil control effect, increased permeability, high moisture retention and other characteristics.
