HEL-40 is a nonionic surfactant with an HLB value between 13 and 15, offering excellent solubilization, emulsification, and dispersion capabilities. Due to its cloud point above 100°C, it can be stably used in both room temperature water systems and high-temperature processes. This product appears as a light yellow paste or viscous liquid, with a viscosity of approximately 500-1000 mPa·s at 25°C. It is recommended to slightly preheat it (e.g., 30-40°C) before use to reduce viscosity for easy pouring and precise weighing.
When used as a high-efficiency solubilizer, the "oil phase addition method" is recommended: pre-mix HEL-40 with the fragrance, essential oil, or fat-soluble active ingredient to be solubilized in a certain ratio (typically solubilizer:oil phase = 1:1 to 5:1) until uniform, then slowly add water under stirring to spontaneously form a transparent or translucent microemulsion. This is suitable for preparing toners, micellar waters, transparent body washes, and similar products. When used as an O/W emulsifier, it can be added to the aqueous phase and heated to 75-80°C, then homogenized with the oil phase heated to the same temperature to form a fine and stable emulsion, widely used in creams, lotions, and other formulations.
In industrial applications, HEL-40 can be directly added to the aqueous phase and stirred to dissolve, preparing a working solution for use. For example, as an emulsifying lubricant component in metalworking fluids, as a leveling agent or softener in textile auxiliaries, and as a low-foaming detergency enhancer in hard surface cleaners. Its excellent acid and alkali resistance and hard water tolerance enable stable performance under complex water quality and working conditions.

Based on the Guoli Chemical product database information and general formulation experience, the recommended dosages for various application fields are as follows:
Before operation, please carefully read the Safety Data Sheet (SDS). Although this product is practically non-toxic and harmless, it is still recommended to wear chemical safety gloves and goggles during handling to avoid direct eye contact. If the product solidifies or becomes cloudy due to low temperature, this is a normal physical phenomenon. Gently heat it in a 30-40°C water bath until transparent to restore usability without affecting quality. Do not expose the product to high temperatures above 60°C for prolonged periods to avoid compromising its solubilization efficiency.
