What are the physicochemical technical parameters of Castor Oil Polyoxyethylene Ether EL-60?

Accepted Answer

Castor Oil Polyoxyethylene Ether EL-60 is a nonionic surctant based on natural castor oil, with an HLB value of approximately 14.5, easily soluble in water, and possesses excellent emulsifying, dispersing, and solubilizing capabilities. Detailed Description Castor Oil Polyoxyethylene Ether EL-60 (CAS No.: 61791-12-6) belongs to the category of nonionic surctants. Its appearance is a pale yellow to yellow viscous liquid or paste. This product is chemically stable, not easily hydrolyzed, and exhibits good alkali resistance, maintaining stable performance in acidic, alkaline, and hard water systems. Its foam characteristic is low foam, making it suitable for formulations where foam generation needs to be suppressed. The core advantage of this product lies in its efficient emulsifying and dispersing ability, which can significantly reduce the oil-water intercial tension and effectively emulsify organic phases such as mineral oils, animal and vegetable oils. Additionally, it has extremely low irritation to human skin and eyes, belonging to the practically non-toxic level, and is rapidly biodegradable with excellent environmental compatibility.

In metalworking fluid formulations, it is recommended for formulating emulsified cutting fluids and grinding fluids, providing synergistic effects of cooling, lubrication, and rust prevention. In textile printing and dyeing, it can be used as a high-temperature leveling agent and dispersant. In daily chemical products, it is commonly used for solubilization and emulsification in transparent shampoos, body washes, and makeup removers. The recommended dosage needs to be determined through experiments based on the oil loading of the specific formulation. Precautions This product has certain hygroscopicity. After opening, it should be sealed and stored immediately to avoid moisture absorption. The solidification point is approximately 5-10°C. Solidification or crystallization may occur under low-temperature environments, which is normal. After slowly warming to room temperature and stirring evenly, it does not affect usage. The storage environment temperature is recommended not to exceed 40°C, and it should be kept away from incompatible substances such as strong oxidizers.
