INGREDIENT OVERVIEW

Sodium Lactate (60% Solution)

Sodium lactate is a water-soluble humectant and buffering agent used in cosmetic formulations to support hydration and contribute to pH stability. It is widely used across cleansers, toners, serums, and emulsions where both moisture retention and formulation balance are required.

Our cosmetic-grade sodium lactate is supplied as a high-purity aqueous solution with a verified active content of 60.8% and L-isomer purity of 98.2% . It is selected for consistent composition, controlled colour (42 APHA) , and reliable batch-to-batch performance.

In formulations, sodium lactate helps attract and retain moisture while supporting a balanced skin feel. It is typically used in combination with other humectants to strengthen hydration systems and improve overall formulation performance.

Formulation examples

Hydrating toner or mist

Sodium lactate: 2–4%
Glycerin: 2–3%
Actives as required
Preserved aqueous base to 100%

Enhances hydration while supporting moisture retention.

Serum or gel system

Sodium lactate: 2–5%
Complementary humectants as required
Polymer thickener: as required
Neutralise and preserve appropriately

Improves hydration performance and contributes to pH stability.

Cream or lotion (emulsion)

Sodium lactate: 1–3% (water phase)

Preserved to finished formula

Supports hydration and contributes to formulation balance

SENSORY PROFILE

Sodium lactate contributes strong hydration but may feel slightly more tacky than glycols at higher use levels. It is typically used in combination with other humectants to balance sensory profile and improve overall formulation feel. Sensory outcome is formulation-dependent; bench testing is recommended.
