【Performance and Application】
1.Safe and non-irritating: The structure of this product is similar to natural phospholipids, extremely mild in nature, almost non-irritating to skin and eyes, and is an ideal cream emulsifier.
2.Excellent emulsification, solubilization and dispersion properties: can emulsify a variety of oil phases including silicone oil.
3.Low surface tension, rich and delicate foam, moderate decontamination and cleansing properties: when used, it produces rich and delicate milky foam, which is easy to clean. The skin feels excellent after cleansing, fresh and clean, not tight, and feels comfortable.
4.Excellent moisturizing performance: When cleaning the skin, it can give the skin a soft, smooth 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: When phosphate is stored under pH=2 conditions for 12 months, its decomposition amount is less than 10%; it will not deteriorate if stored under neutral or slightly acidic conditions for one year or more.
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.
【Use and Dosage】
1.Especially used for preparing foam cleansers and foam cleansers that are currently popular in the market. It is also suitable for preparing refreshing and smooth body wash and other mid-to-high-end low-irritation cleaning and hygiene products such as shampoo, foam facial cleanser, and shower gel. 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, when formulating, it is necessary to add an anti-hard water agent (such as EDTA) or a hard water-resistant surfactant (such as sulfobetaine) to be compatible with it to achieve its excellent performance. performance.
3.Recommended dosage: foam cleanser: 10 to 50%, shower gel: 8 to 15%.
