Uses of Sodium Lactate in Bath and Bodycare Formulation

  • Non-Sticky, Light-Weight Humectant: When added to emulsion-type formulations such as lotions, Sodium Lactate helps moisturize the skin without feeling sticky/ tacky (like glycerin does), and also helps prevent lotions from drying out if left open
  • Soap Hardening Agent: Sodium Lactate helps create firmer, harder bar soaps, which have the benefit of lasting longer in the bathroom (preventing soaps from going moist/ soggy). *As a result of the hardening effect, Sodium Lactate makes your bar soaps cure/ dry faster
  • Soap Texture Enhancer: In hot process soaps, Sodium Lactate helps create smooth and creamy bar soaps that are firm/ hard
  • Preservative Booster: Sodium Lactate is commonly used as a preservative in the food industry
  • PH Stabilizer/ Buffering Agent: Sodium Lactate helps adjust a product’s PH value to within the skin’s natural PH, without  a need for PH adjusting
