Science
Mechanism of Action
This ingredient operates by leveraging the distinct biological activities of its constituent compounds. The taurine component contributes to maintaining skin homeostasis through its osmoregulatory and antioxidant properties. It has demonstrated the capacity to suppress transepidermal water loss (TEWL) and stimulate the mRNA expression of critical barrier proteins like ceramide synthase 4 and filaggrin in 3D-cultured epidermis. Furthermore, taurine treatment has been shown to increase hyaluronic acid (HA) synthase-2 mRNA expression, leading to enhanced HA production in dermal fibroblasts. Concurrently, the potassium aspartate fraction aids in restoring the skin’s protective barrier and diminishing the look of skin redness.

Stability
This ingredient is water-soluble. While specific optimal pH ranges are not explicitly defined for the combined molecule, studies on taurine in other biological contexts suggest stability around a neutral pH, such as pH 7.4. However, it is noted that 'Potassium Taurine Lauryl/Myristyl Aspartate' may present formulation challenges concerning aesthetics or stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet assessed 'Potassium Taurine Lauryl Aspartate'. While 'Potassium Aspartate' alone was deemed 'safe as used' by CIR at concentrations ranging from 0.003% to 0.008% in cosmetic products, this assessment does not apply to the combined ingredient. No specific SCCS or FDA status has been identified for Potassium Taurine Lauryl Aspartate.
