Benefits: Helps retain moisture, promotes skin hydration, and can be used as a pH adjuster.
Skin type suitability/concerns: Suitable for all skin types.
Target audience: All age groups and demographics.
Chemical composition: Sodium lactate is a sodium salt with the molecular formula C3H5NaO3.
Physical aspect: White, crystalline powder or clear, colorless, odorless, viscous liquid.
Compatibility: Compatible with a wide range of cosmetic ingredients, including water, oils, and emulsifiers.
Concentration: Typically used at 0.5-5% in cosmetic formulations.
Side effects/adverse reactions: Generally safe for use in cosmetics, but may cause irritation or allergic reactions in some individuals, especially at high concentrations.
Regulatory status: Approved for use in cosmetics worldwide, with no specific restrictions.
