SODIUM BOROHYDRIDE
Description
Sodium borohydride is a potent reducing agent with applications in skincare formulations. This inorganic compound, with the chemical formula NaBH4, is a white crystalline powder that readily dissolves in water. In cosmetic products, sodium borohydride serves primarily as a stabilizing and preservative agent.
The compound's reducing properties make it effective in preventing oxidation of other ingredients, particularly in formulations containing sensitive actives or natural extracts. It can help maintain the efficacy and color stability of products over time. Sodium borohydride is also utilized in the synthesis of certain cosmetic ingredients, playing a role in the production of specialized polymers and surfactants.
In skincare, sodium borohydride is used at very low concentrations, typically below 0.1%. At these levels, it is generally considered safe for topical application. However, formulators must exercise caution due to its reactivity. Proper pH control and compatibility testing are crucial when incorporating this ingredient.
While not a direct skin benefit agent, sodium borohydride's role in preserving product integrity indirectly contributes to the overall effectiveness and shelf-life of skincare formulations. Its use is more common in professional-grade products and those requiring enhanced stability.
