SODIUM CARBONATE

Description

Sodium carbonate, also known as soda ash or washing soda, is a versatile alkaline compound with applications in skincare and cosmetic formulations. This white, odorless powder has a pH of around 11.5 in aqueous solution, making it an effective pH adjuster and buffering agent. In skincare products, sodium carbonate primarily functions as an emulsifier, helping to stabilize oil-in-water formulations and enhance the texture of creams and lotions.

The ingredient's alkaline nature allows it to act as a mild exfoliant, assisting in the removal of dead skin cells and promoting a smoother skin surface. Sodium carbonate also exhibits water-softening properties, which can be beneficial in cleansing formulations by enhancing their efficacy in hard water conditions. Additionally, it serves as a preservative booster, helping to maintain product stability and extend shelf life.

While sodium carbonate offers various benefits in skincare formulations, its high alkalinity necessitates careful use and proper concentration control to avoid potential skin irritation. Formulators must balance its functionality with skin compatibility, often incorporating it at lower concentrations or neutralizing it with acids to achieve optimal results in finished products.
