[Performance and application]
1.Safe and non irritating: the product is similar to natural phospholipids in structure, extremely mild in nature and almost non irritating to skin and eyes. It is an ideal cream emulsifier.
2.Excellent emulsifying, solubilizing and dispersing properties: it can emulsify a variety of oil phases including silicone oil.
3.Low surface tension, rich and delicate foam, decontamination and cleanliness is moderate: when used, produce rich and fine milk foam, easy to clean, skin clean after feeling very excellent, clean and clean, not tight, feel comfortable.
4.Excellent moisturizing performance: when cleaning the skin, it can give the skin a soft, smooth and refreshing feeling. Antistatic and softening effect is obvious. It is also suitable for shampoo, hair additives and fabric fiber finishing agents.
5.Acid, alkali and salt resistance: phosphate ester is stored at pH = 2 for 12 months, and its decomposition amount is less than 10%; If it is stored under neutral or slightly acidic conditions for one year or more, it 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: potassium phosphate is a low toxicity. The LD50 / (mg / kg) for mice is 74000 and the LC50 / (mg / kg) for fish is 3400-12800.
[Purpose and dosage]
1.Liquid soap cleansing foam and foam cleansing foam, which are widely used in the market, are also suitable for making clear, smooth and liquid soap bath products, such as shampoo, foam cleansing cream, bath liquid, hand washing liquid, mild baby care products, children's bathing and shampoo products.
2.The hard water resistance is slightly worse than other anionic surfactants. Therefore, when formulating, attention should be paid to adding hard water resistant agent (such as EDTA) or hard water resistant surfactant (such as sulfobetaine) to play its excellent performance.
