Sodium Lactate 60% (Liquid)

Description

Sodium Lactate is a highly concentrated plant-derived liquid humectant used in lotions to deeply hydrate/moisturize the skin. It is also used to speed up hardening and curing time in cold-process soap making. It is a more effective humectant than Glycerin, with the ability to hold twice the amount water.

Sodium Lactate is the sodium salt of Lactic Acid, and can be found in the ingredient labels of many types of products including lotions, hair products, cleansers and soaps.

Uses of Sodium Lactate in Bath and Bodycare Formulations

• 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
