Acetylation modification increases the lipophilicity of HA, making it more compatible with the skin's lipid bilayer for deeper penetration than standard HA.
Acetyl groups slow down the rapid binding and release of water molecules by HA, extending the duration of hydration on the skin surface.
With protein content ≤ 0.1% and strictly controlled microbial levels, it meets the highest safety standards for cosmetic raw materials.
Stable within the pH 5.0–8.5 range, making it ideal for a wide variety of serum and emulsion formulation systems.
Maintains ≥ 99% transmittance in 80% ethanol solutions, perfect for alcohol-containing essences and toners without precipitation.
As Sodium Acetylated Hyaluronate, it allows for formulation differentiation and positioning in the premium/high-end skincare market.
Core moisturizing active for high-end serums, providing longer-lasting dermal hydration compared to standard hyaluronic acid.
Acetylation enhances skin barrier compatibility, making it suitable for repair-focused formulas and sensitive skin products.
Maintains high transparency and zero precipitation in alcohol-rich systems, ideal for toners and watery essences.
A differentiated ingredient for professional and medical-grade skincare, supporting premium product positioning and value.
Positively charged HA for hair care and wash-off skin products with high substantivity.
