Beyond its use in skin care and makeup, sodium formate is often also found in hair care formulations for the same benefit. In its raw material form, sodium formate is a water soluble white or colorless powder. The Cosmetic Ingredient Review Expert Panel has deemed the usage of sodium formate in cosmetic formulations safe in concentrations up to 0.34%.
