Sodium anisate is a salt of sodium and p-anisic (4-methoxy benzoic) acid. p-Anisic acid is an antiseptic, antioxidant, anti-inflammatory, and anti-tumor, white crystalline solid found naturally in anise. It is commonly used in cosmetic products as an antimicrobial preservative. However, p-anisic acid is insoluble in water but dissolve in some alcohols, ethers, and/or esters; which makes it challenging to efficiently integrate into many water- or emulsion-based formulations. Interestingly, sodium anisate, a sodium salt of anisic acid, is easily dissolved in water (13-145g/L) which makes it easy to integrate in formulations. Additionally, sodium anisate can be paired with sodium levulinate, potassium sorbate, or other ingredients in anti-aging serum, lotions, restoration and anti-wrinkle creams, mascara, etc. A popular sodium anisate combo is Evonik's Dermorganics 1388 which pairs sodium anisate with sodium levulinate in creating an effective germ-fighting formula.
Established uses of sodium anisate include:
• Antimicrobial ingredient
• Odor masking agent
• Culture media ingredient
• Synthetic reagent and intermediate
