【Performance and application】
1. Safe and non-irritating: The structure of this product is similar to natural phospholipids. It is extremely mild in nature and almost non-irritating to the skin and eyes. It is an ideal cream emulsifier.
2. Excellent emulsifying, solubilizing and dispersing properties: It can emulsify various oil phases including silicone oil.
3. Low surface tension, rich and fine foam, moderate decontamination and washing performance: when used, it produces rich and fine milky foam, which is easy to clean, and the skin feels very good after cleaning, refreshing and clean without tightness, and feels more comfortable.
4. Excellent moisturizing performance: when cleaning the skin, it can give the skin a soft, lubricated and refreshing feeling. It has obvious antistatic and softening effects, and is also suitable for use in shampoos, hair product additives, and fabric fiber finishing agents.
5. Acid, alkali and salt resistance: Phosphate esters can be stored at pH=2 for 12 months, and their decomposition rate is less than 10%; if they are stored in neutral or slightly acidic conditions for one year or longer, they will not deteriorate.
6. Good biodegradability: The biodegradation of alkyl phosphate is similar to that of sodium alkyl alcohol sulfate, and can be decomposed into carbon dioxide and phosphate ions.
7. Low toxicity: Phosphate potassium salt is a low toxicity substance. The LD50/(mg/kg) for mice is 74000, and the LC50/(mg/kg) for fish is 3400-12800.
【Usage and Dosage】
1. Use: It is especially used to prepare foam cleanser and foam cleanser which are widely popular in the market. It is also suitable for preparing medium and high-grade low-irritant cleansing and hygiene products such as shampoo, foam cleanser, bath soap, etc. liquid, hand soap, mild baby care products, children's bath and shampoo products.
2. The resistance to hard water is slightly worse than that of other anionic surfactants. Therefore, attention should be paid to adding anti-hard water agents (such as EDTA) or compatibility with hard water-resistant surfactants (such as sulfobetaine) when formulating, so as to exert its excellent performance.
3. Recommended dosage: foam cleanser: 10-50%, shower gel: 8-15%.
