Sodium phosphate monobasic ——a PH regulator in cosmetics

Sodium phosphate monobasic has a CAS number of 7558-80-7 and a molecular formula of H2NaO4P. In the cosmetic industry, it adjusts the pH of cosmetic products to ensure that they are within the appropriate range, thus maintaining product stability and safety.

1.Basic properties of Sodium phosphate monobasic

Sodium phosphate monobasic is colorless or white rhombohedral crystal. Relative density is 1.91, melting point is 60℃. Soluble in water, its aqueous solution is acidic; insoluble in alcohol. It is easy to agglomerate in wet air. When heated to 95 ° C dehydration into anhydrous, in 190 ~ 204 ° C into acid sodium pyrophosphate, in 204 ~ 244 ° C when the formation of sodium metaphosphate. Its chemical nature is more active, therefore, in the production, use and storage, must take strict safety measures to prevent moisture, heat or sunlight, to prevent impact, friction and strong vibration, to avoid contact with the skin to avoid burns to the skin and eyes, and stored in a cool and dry place.

2.Sodium phosphate monobasic application in cosmetics

(1) pH regulation

Skin and hair are in a weakly acidic state under normal conditions. The pH of skin is roughly between 5.5 and 7.0, and hair is neutral to weakly acidic. Therefore, cosmetic products need to maintain a certain pH to maintain the normal pH of skin and hair.Sodium phosphate monobasic is used as a pH regulator in cosmetic products to provide an acidic environment and ensure that the pH of cosmetic products matches the pH of skin and hair, thus reducing irritation and damage to the skin.

(2) Stability enhancement

Sodium phosphate monobasic not only helps to maintain the pH of cosmetics, but also enhances the stability of the product. By interacting with other ingredients in cosmetics, it enhances the antioxidant properties of the product, preventing oxidative deterioration of the ingredients and extending the shelf life of the product.

(3) Texture enhancement

The addition of Sodium phosphate monobasic can also enhance the texture of cosmetics. It can enhance the moisturizing effect of the product, making the skin more hydrated and smooth. At the same time, it also helps to improve the elasticity and softness of the skin, so that the skin feels better to the touch.

(4) Safety

Sodium phosphate monobasic is relatively safe for use in cosmetics, with a risk factor of 1. It generally has no effect on pregnant women and is not acne-causing. This makes it the pH regulator of choice for many cosmetic brands.

The demand for cosmetic raw materials is increasing year by year, and the production of Sodium phosphate monobasic produced by Jiurunfa Chemical Technology is also increasing year by year, meanwhile, with the continuous upgrading of the consumption of cosmetic products, Jiurunfa Chemical Technology is constantly optimizing the equipment and refining the standard to improve the quality for the customers' use. At the same time, with the continuous upgrading of cosmetic consumption, Jiurunfa Chemical Technology Company is constantly optimizing its equipment, refining its standards, and improving its quality in order to guarantee the use of its customers.
