Application:
PromaCare® TA-Encap is suitable for brightening-focused toner, mask, essence, lotion and cream formulations. It offers excellent water dispersibility and good compatibility with most thickeners and emulsifiers, with minimal impact on transparency and viscosity at typical use levels. For processing, add during the low-temperature stage (≤50°C) under low-speed shear and mix until homogeneous. The compatible formulation pH range is 4.0-8.0.
Key Benefits:
Enhanced skin delivery and retention
Carrier-mediated delivery improves the penetration and skin retention of tranexamic acid compared with free tranexamic acid, helping the active reach relevant skin target sites more effectively.
Multi-pathway skin-brightening performance
PromaCare® TA-Encap inhibits tyrosinase activity and melanin production and down-regulates melanin-related TYR and MITF expression. 3D reconstructed-skin testing also showed increased skin brightness and reduced melanin content.
Soothing and anti-inflammatory support
Cell-based testing showed significant inhibition of inflammatory mediators IL-6 and PGE2 versus the model group, supporting its suitability for brightening systems designed for sensitive or uneven-looking skin.
Good stability and formulation compatibility
Tranexamic acid retention remained above 98% after 90 days of room-temperature storage in the stability study. The product is water-dispersible, compatible with transparent systems, and can be used across toner, essence, mask, lotion and cream formats.
