Sodium polyacrylate is a common cosmetic ingredient, also known as sodium acrylate copolymer. It plays multiple roles in cosmetics, and the following are some common applications:
Stability and Thickener: Sodium polyacrylate can increase the viscosity and viscosity of cosmetic products, making them easier to use and manipulate. It can prevent the separation and precipitation of other components in cosmetics, and improve the stability of the product.
Humectant: Due to its good moisturizing properties, sodium polyacrylate can absorb moisture from the environment and lock it onto the surface of the skin, thereby increasing the moisture content of the skin and improving its moisture and softness.
Dispersants and emulsifiers: Sodium polyacrylate can help to evenly disperse oily components in water-based formulas, or to evenly disperse water-based components in oil-based formulas, thereby achieving emulsification and stability effects.
Oil control agent: For skin prone to oil production, sodium polyacrylate has the ability to adsorb oil, which can reduce the secretion of oil on the skin surface and make the skin look more refreshing.
PH regulator: Sodium polyacrylate can adjust the pH value of cosmetic products to adapt to the natural acid-base balance of the skin, providing a better user experience and skin compatibility.
It should be noted that the amount of sodium polyacrylate used as a cosmetic ingredient should be within a safe range and comply with relevant formula guidance and regulatory requirements. For individuals who have special skin conditions or a history of allergies when using cosmetics, it is recommended to undergo skin testing first and consult professional advice.
