SODIUM ALUMINATE.

Questionable CAS 1302-42-7 / ANTICORROSIVE, BUFFERING

Sodium Aluminate functions as a potent alkaline buffering agent, introducing aluminum ions to meticulously control and stabilize pH levels within cosmetic formulations. Its integration demands rigorous precision and exceptionally low concentrations to guarantee the final product's safety and non-corrosive nature.

pH Adjuster Buffering Agent

Science

This alkaline substance operates as a buffering agent, leveraging aluminum ions to precisely adjust and maintain a stable pH within formulations. This mechanism is crucial for preserving the integrity of a product and ensuring optimal activity of other sensitive ingredients.
