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

Sodium lauroyl lactylate is a salt of 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 to improve the shelf life of products by inhibiting the growth of microorganisms. There are no restrictions on the use of sodium levulinate in cosmetic products in the European Union and it is considered to be non-irritating and harmless(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 cosmetics and foodstuffs.

Sodium phytate is the sodium salt of phytic acid, which is extracted from plants and acts as a chelating agent. Chelating agents are substances that are used in cosmetic products to neutralize metal ions in the formulation.(1) The special feature of this chelating agent is that it not only acts as a preservative, but also has 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) serves as an emulsifier. Emulsifiers are additives that are used in cosmetic formulations to combine two actually immiscible phases, such as oil and water, into a stable, uniform emulsion(1).
