3. Product Characteristics​

3.1 Surface Activity​

OA - 16 - 26% Oxide Ammonium exhibits excellent surface - active properties. It can significantly reduce the surface tension of water. At the critical micelle concentration, the surface tension of water can be decreased to approximately 30×10⁻³ N/m. This property enables it to effectively lower the interfacial tension between different phases, facilitating the dispersion, emulsification, and wetting processes in various formulations.​

3.2 Thickening Property​

It possesses good thickening capabilities. When added to product formulations such as liquid detergents and personal care products, it can effectively adjust the viscosity. For example, in shower gels, it helps to create a more viscous and luxurious texture, enhancing the product's stability and user experience. The thickening effect is achieved through its interaction with other ingredients in the formulation, promoting the formation of a more structured and viscous system.​

3.3 Foaming and Foam - Stabilizing Property​

It serves as an efficient foam - stabilizing agent. In applications like shampoos and dishwashing detergents, it can generate rich and stable foam. The foam generated is fine - textured and has a long - lasting quality, which is beneficial for improving the cleaning effect. In shampoos, the stable foam can better carry away dirt and sebum from the hair, while in dishwashing detergents, it helps to adhere to the surface of dishes and utensils, enhancing the cleaning power.​

3.4 Mildness​

This product is mild in nature. It has extremely low irritation to the skin and eyes, making it suitable for use in products that require high - level safety and mildness, such as baby care products and facial cleansers for sensitive skin. Its non - toxic property also ensures that it poses no harm to human health during normal use. Additionally, it has good biodegradability. After 2 weeks, it can be degraded by about 88%, and after 4 weeks, the degradation rate reaches 93%, which is in line with the requirements of environmental protection.​

3.5 Compatibility​

OA - 16 - 26% Oxide Ammonium shows excellent compatibility with various types of surfactants, including anionic surfactants like sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), cationic surfactants such as cetrimonium bromide, non - ionic surfactants like polyethylene glycol - based surfactants, and amphoteric surfactants. This wide compatibility allows formulators to create complex and well - balanced product systems, combining the advantages of different surfactants to achieve optimal performance.​

4. Main Applications​

4.1 Personal Care Field​

• Shampoos: Widely used in shampoos, it can make hair softer, more manageable, and easier to comb. It also contributes to the generation of fine and abundant foam, and imparts a natural shine to the hair. By reducing static electricity in the hair, it helps to prevent hair frizz, leaving the hair in a smoother and more lustrous state.​

• Body Washes and Shower Gels: In body washes and shower gels, it provides a rich and creamy lather, enhancing the user's bathing experience. Its mild nature ensures that it does not cause irritation to the skin, and the softening property leaves the skin feeling smooth and moisturized after washing.​

4.2 Cleaning Field​

• Hard - Surface Cleaners: It can be used in hard - surface cleaners for dishes, bathrooms, and building exteriors. In dishwashing detergents, it not only helps to thicken the product, making it easier to apply and adhere to dish surfaces, but also reduces the irritation of other ingredients in the detergent. In bathroom cleaners, it can enhance the cleaning effect on tiles, sinks, and toilets, and in building exterior cleaners, it can assist in removing dirt and stains from walls and facades.​

5. Packaging and Storage​

5.1 Packaging​

Commonly packaged in 50 - kg or 200 - kg plastic drums. The plastic packaging material provides good chemical resistance, preventing any potential reaction between the product and the container, and ensuring the quality and stability of the product during storage and transportation.​

5.2 Storage​

Should be stored in a cool, dry place, away from direct sunlight and heat sources. The recommended storage temperature is generally below 30°C. Under proper storage conditions, the shelf life of the product is usually one year. However, it is advisable to periodically check the product quality to ensure its performance remains optimal before use.​

6. Safety Precautions​

• Avoid Contact: Avoid contact with eyes and skin. In case of accidental contact with eyes, immediately rinse with plenty of water for at least 15 minutes and seek medical attention if necessary. If in contact with skin, wash the affected area thoroughly with soap and water.​

• Handling: When handling the product, it is recommended to wear appropriate personal protective equipment, such as chemical - resistant gloves, safety glasses, and a lab coat, to prevent any potential exposure.​

• Ventilation: Ensure good ventilation in the storage and handling areas to prevent the accumulation of vapors.
