Alternatives to TEA for pH Adjustment in Serum

Triethanolamine (TEA) is commonly used to adjust the pH of cosmetic formulations. If you are looking for an alternative for your serum formulation at a concentration of around 0.10%, Sodium Hydroxide is a suitable option.

Sodium Hydroxide is a strong alkali used to increase the pH (make it more alkaline) in cosmetic products. It is effective even at low concentrations.

• Usage Rate: Sodium Hydroxide is typically used at a rate of 0.1% to 5% in cosmetic formulations, making it suitable for your intended concentration of 0.10%.

Always add pH adjusters gradually and check the pH with a pH meter until the desired pH is reached, as the exact amount needed can vary depending on the other ingredients in your formulation.
