Sodium lactate, a highly moisturizing active ingredient that increases the skin's water-binding capacity.(1)

Sodium lauroyl lactylate is a salt formed from lactate and lauric acid. It acts as an emulsifier and also has excellent wetting and antibacterial properties.(1)

Sodium levulinate is the sodium salt of levulinic acid. As a preservative, it can help improve the shelf life of products by inhibiting the growth of microorganisms. In the European Union, there are no restrictions on the use of sodium levulinate in cosmetic products; it is considered non-irritating and safe.(1)

Sodium linoleate is the sodium salt of linoleic acid. It acts as an emulsifier and viscosity regulator.(1)

Sodium metabisulfite is a preservative. It is used in both cosmetics and food products.(1)

Sodium phytate is the sodium salt of phytic acid, which is derived from plants and acts as a chelating agent. Chelating agents are substances used in cosmetic products to neutralize metal ions in the formulation.(1) What makes this chelating agent unique is that it not only acts as a preservative but also possesses antioxidant properties.(2)

Sodium polyglutamate is the sodium salt of polyglutamic acid, a biopolymer obtained through fermentation consisting of linked glutamic acid units. Due to its high molecular weight, it acts primarily on the skin’s surface, where it forms a moisture-retaining film. The active ingredient provides immediate hydration, improves skin elasticity, and leaves the skin feeling pleasant. It can also enhance the stability of hyaluronic acid. (1-3)

Sodium Stearoyl Lactylate (SSL) acts as an emulsifier. Emulsifiers are excipients used in cosmetic formulations to combine two phases that are normally immiscible—such as oil and water—into a stable, uniform emulsion.(1)
