4. Product Features
- Thickening: It has excellent thickening properties and can effectively adjust the viscosity of products. When combined with other surfactants, such as anionic surfactants like AES (Sodium Lauryl Ether Sulfate), it can significantly increase the viscosity of the formulation, providing a more desirable consistency for products like shampoos and liquid soaps.
- Antistatic: Can endow hair and skin with antistatic properties. In hair care products, it reduces static electricity, making hair easier to comb and more manageable. In fabric softeners, it helps to eliminate static cling in textiles, improving their handling and wear comfort.
- Softening: Imparts a softening effect to both hair and skin. In skin care products, it leaves the skin feeling smooth and soft, enhancing the overall user experience. In hair care, it contributes to making hair soft and lustrous.
- Foaming and Foam - Stabilizing: As an efficient foam - stabilizing agent, it can generate rich, fine, and long - lasting foam. In detergent products such as dishwashing liquids and body washes, its foam - enhancing property not only improves the cleaning effect but also provides a luxurious foaming experience for users.
- Decontamination: When combined with certain anionic surfactants, it shows a synergistic effect on decontamination. For example, in combination with AS (Sodium Alkyl Sulfate), it can enhance the cleaning power of detergents, effectively removing dirt, oil, and stains.
- Low Irritation: It is extremely mild to the skin and eyes, with low irritation. It can effectively reduce the irritation of anionic surfactants in detergent formulations, making it suitable for use in products for sensitive skin, such as baby shampoos and facial cleansers.
- Good Compatibility: It has excellent compatibility with various surfactants, including anionic, cationic, amphoteric, and non - ionic surfactants. This allows for flexible formulation design, enabling manufacturers to create products with enhanced overall performance.
- Biodegradability: It is biodegradable, which means it can be decomposed by natural microorganisms in the environment, reducing its impact on the ecosystem and making it an environmentally friendly choice.
5. Main Applications
- Shampoos: Widely used in shampoos, it makes hair more compliant, easier to comb, and gives a rich and stable foam. It also helps to improve the overall hair - care effect, leaving hair with a natural shine.
- Body Washes and Shower Gels: In body washes and shower gels, it provides rich foam and a gentle cleansing effect, while its softening property leaves the skin feeling smooth and moisturized.
- Facial Cleansers: For facial cleansers, especially those for sensitive skin, its mild nature ensures gentle cleansing without stripping the skin of its natural moisture.
- Household Cleaning Products:
- Dishwashing Detergents: In dishwashing detergents, it acts as a foam - enhancing and foam - stabilizing agent, improving the cleaning performance and providing a better user experience.
- Hard - Surface Cleaners: Used in cleaners for hard surfaces such as kitchens, bathrooms, and floors, it helps to thicken the product, reduces the irritation of other ingredients, and enhances the cleaning effect.
- Industrial Applications:
- Textile Industry: In the textile industry, it can be used as an antistatic agent, softener, and emulsifier. It helps to improve the processing performance of textiles, reduce static electricity during spinning and weaving, and make the fabric feel softer.
- Cosmetics Industry: It can also be used as an ingredient in cosmetics such as creams, lotions, and gels, playing roles such as thickening, emulsifying, and stabilizing.
6. Usage Method
The recommended dosage varies depending on the specific application. Generally:
- In personal care products like shampoos and body washes, the dosage is usually 3 - 10%.
- In household cleaning products such as dishwashing detergents and hard - surface cleaners, it can be used at a concentration of 2 - 8%.
- In industrial applications, the dosage may be adjusted according to the specific process requirements, typically in the range of 1 - 15%.
7. Packaging and Storage
- Packaging: Usually packaged in 200 - L plastic drums, with a net weight of 200 kg per drum. It can also be provided in other packaging sizes according to customer requirements, such as 50 - L plastic barrels.
- Storage: Should be stored in a cool, dry, and well - ventilated place, away from direct sunlight and heat sources. Avoid storage in areas with high humidity to prevent product deterioration. The shelf life is generally 1 - 2 years under proper storage conditions.
8. Safety Precautions
- Toxicity: It is of low toxicity, but direct contact with concentrated solutions should be avoided.
- Skin and Eye Contact: In case of contact with skin, wash thoroughly with soap and water. If it gets into the eyes, rinse immediately with plenty of water and seek medical advice.
- Handling: When handling the product, it is recommended to wear appropriate personal protective equipment, such as gloves and safety glasses, to prevent direct contact.
