Chemical Structure
Basic Info
Stealth 21 is a non-ionic surfactant with the characteristics of low foaming and good biodegradability. Due to the presence of ester bonds in the chemical structure, stearic acid polyoxyethylene ether is not stable enough in terms of heat, acid, alkali, etc., and its solubility is not as good as ethers.
The surface activity of Stealth 21 is moderate, but its activity and cleaning power are not as good as alcohol ethers and phenol ethers. It belongs to the low foaming surfactant class and is widely used in the textile industry, industrial cleaning, and personal care fields.
Packaging for Stealth 21
Steareth 21 iron drum packaging, 200Kg/drum; Or fully plastic drum packaging, 50Kg/drum; Plastic woven bag packaging, 25Kg/bag.
Storage and transportation of Stealth 21
Stealth 21 should be stored in a cool, ventilated, and dry place and transported as a general chemical
The chemical properties of Stealth 21 are white flakes that are dispersed in water and have good emulsifying and cleaning properties.

Product Packaging
Stealth 21 is a surfactant widely used in many industrial and daily products. Stealth 21 is produced by the reaction of stearic acid and polyethylene oxide (PEO, usually ethoxylated). The main uses of Stealth 21 include:
1. Cosmetics and personal care products:
Lotion and face cream: Steareth 21 acts as an emulsifier, and polyoxyethylene stearate helps water phase combine with oil to form a stable lotion.
Shampoo and body wash: Stealth 21, as a cleaner and surfactant, can effectively remove oil and impurities from the skin and hair.
Sunscreen: In sunscreen formulations, Stealth 21 can serve as an emulsifier and help improve product stability.
2. Drug formula:
Stealth 21 is used as an emulsifier for drugs to prepare emulsion type drugs (such as water in oil emulsions), helping to evenly disperse drug components and improve drug bioavailability.
3. Food industry:
Food additive: Stealth 21 is used as an emulsifier in certain foods to aid in oil-water mixing, improve taste and stability.
For example, in some chocolates, creams, and other processed foods, polyoxyethylene stearate may be used to enhance the texture of the product.
4. Detergents and cleaning products:
Steareth 21, as a surfactant, plays a synergistic role in cleaning agents and detergents, improving their ability to remove dirt.
5. Plastic and coating industry:
Stealth 21 is used as an additive in certain plastic formulations to improve the flowability and stability of plastics.
As a dispersant in coatings, it helps improve the uniformity and adhesion of the coating.
6. Pesticides and agricultural chemicals:
Stealth 21 is used as an emulsifier in pesticide formulations to help evenly disperse pesticides and enhance their adhesion to plant surfaces.
The application of Stealth 21 is very extensive, mainly utilizing its excellent emulsification, surface activity, and stability, playing an important role in multiple fields.
