ⓘ Multi-weight HA blends (e.g. Nano + High MW) available for multi-layer hydration formulations. Inquire for custom blending options.
Produced via microbial fermentation — no animal tissue, no risk of animal-derived contaminants. Delivers a structurally consistent HA with traceable, documented production process.
Exceptional solubility and transparency in aqueous systems — forms clear, particle-free solutions ideal for serums, essences, and gel formulations where visual clarity is critical.
Meets ISO cosmetic microbiological standards: Total Aerobic Count ≤ 100 CFU/g, Pseudomonas aeruginosa and Staphylococcus aureus absent — fully compliant with EU Cosmetics Regulation.
Heavy metal limits aligned with EU Cosmetics Regulation (EC) No 1223/2009 — particularly Pb ≤ 2 ppm and Hg ≤ 0.1 ppm. Full INCI documentation available.
From Nano HA (< 800 Da) for deep penetration to High MW HA (> 1,500,000 Da) for surface film-forming — all grades from a single, audited manufacturing site.
Protein content ≤ 0.1% minimizes sensitization risk in cosmetic formulations — an important parameter for products targeting sensitive skin and clean beauty positioning.
Cosmetic grade sodium hyaluronate is a versatile active ingredient used across all major skincare and personal care product categories.
Lightweight aqueous formulas where high MW HA provides surface hydration and nano/low MW grades deliver deep penetration — the ideal multi-layer hydration system.
Combined with retinol, peptides, or niacinamide in premium anti-aging formulations. HA provides the hydration matrix that improves the tolerability and delivery of active ingredients.
High MW HA is the backbone of hydrogel and sheet mask formulations — its exceptional water-binding capacity (up to 1,000× its weight) delivers an intensive hydration effect.
Used in foundations, BB creams, and lip products to improve texture, spreadability, and skin-feel. Low MW grades preferred for their compatibility with pigment systems.
Water-soluble, non-sticky hydration layer applied before serum and moisturizer steps. Hydrolyzed HA and nano HA grades are ideal for toners and facial mist applications.
Fragrance-free, low-irritation formulations for sensitive periocular and lip areas — HA provides plumping hydration with minimal sensitization risk at these application sites.
Incorporated into SPF emulsions to offset the potential drying effect of UV filters, improve skin feel, and contribute to the overall moisturization profile of the formula.
Low MW HA added to facial cleansers, micellar waters, and rinse-off treatments to maintain the skin barrier moisture level post-cleansing.
