Ethylhexylglycerin, with the CAS number 70445-33-9, is a high - quality chemical product. It is a clear, colorless to slightly yellowish liquid with a mild characteristic odor. The molecular formula of Ethylhexylglycerin is C11H24O3, and its molecular weight is approximately 204.30 g/mol. It has excellent solubility properties. It is soluble in most organic solvents such as ethanol, propylene glycol, and fatty acids, while having limited solubility in water. This product is known for its high - quality standards, ensuring its reliability for various applications.
1. Cosmetic Industry: Ethylhexylglycerin is widely used as a co - preservative in cosmetics. It enhances the effectiveness of traditional preservatives like parabens and phenoxyethanol, allowing for lower concentrations of these potentially harmful substances. It also functions as a skin - conditioning agent, imparting a smooth and soft feel to the skin. In addition, it can be used in hair care products to improve the manageability of hair.
2. Pharmaceutical Industry: In pharmaceutical formulations, it can act as a solubilizer and emulsifier. It helps in the dissolution of poorly soluble drugs and stabilizes emulsions, ensuring the uniformity and stability of the pharmaceutical products.
3. Food Industry: Although used in a more limited capacity, it can be used as a flavor enhancer and a solvent for certain food additives, providing a mild and pleasant taste.
1. Cosmetic Formulations: When formulating cosmetics, Ethylhexylglycerin can be added at a concentration ranging from 0.5% to 5%. It is typically added during the cooling phase of the manufacturing process to prevent thermal degradation. First, dissolve it in a suitable solvent such as ethanol or propylene glycol, and then slowly add it to the cosmetic base with continuous stirring.
2. Pharmaceutical Applications: In pharmaceutical preparations, the dosage depends on the specific formulation and the drug being used. It is recommended to conduct compatibility studies before use. Usually, it is added during the mixing stage of the formulation, and the mixture should be homogenized thoroughly to ensure proper dispersion.
3. Food Applications: When used in the food industry, it should comply with relevant food safety regulations. The concentration is usually very low, generally less than 0.1%. It can be added directly to the food product during the mixing process.
1. Cosmetic Case: A well - known skincare brand was facing challenges with the stability of its moisturizer. The product was experiencing phase separation and had a short shelf - life due to the low - efficiency preservative system. After replacing part of the traditional preservative with Ethylhexylglycerin at a concentration of 2%, the product's stability was significantly improved. The phase separation was eliminated, and the shelf - life was extended from 6 months to 12 months. Consumers also reported that the moisturizer felt smoother on the skin.
2. Pharmaceutical Case: A pharmaceutical company was developing a topical cream for skin infections. The active ingredient in the cream had poor solubility, which affected the drug's bioavailability. By adding Ethylhexylglycerin as a solubilizer at a concentration of 3%, the solubility of the active ingredient was greatly enhanced. Clinical trials showed that the new formulation had a higher cure rate compared to the previous formulation without Ethylhexylglycerin.
3. Food Case: A small - scale food producer was trying to improve the flavor of its fruit - based beverages. By adding Ethylhexylglycerin at a concentration of 0.05%, the beverages had a more intense and pleasant fruit flavor. The product became more popular in the market, leading to an increase in sales.
