“Closest ingredient-family evidence: topical nano-hyaluronic acid improved skin hydration and reduced wrinkle depth in a human cosmetic study.”
HyaOil™ (Oil-Dispersed Hyaluronic Acid)
Cosmetics
Code: 7407
Oil-dispersed hyaluronic acid microspheres for lipsticks, lip balms and oil-based makeup that need HA moisturising positioning.
HyaOil™ is oil-dispersed hyaluronic acid for anhydrous and oil-based cosmetic systems.
The product contains approximately 30% sodium hyaluronate microspheres dispersed in castor oil and hydrogenated castor oil, allowing hyaluronic acid to be used in lipsticks, lip balms and oil-based makeup.
It is supplied as an ivory-white to light-yellow semi-solid ointment.
Product Description: Use HyaOil™ when a formula needs hyaluronic acid positioning in an oil phase where ordinary sodium hyaluronate powder cannot dissolve. The microsphere dispersion allows incorporation into heated oil systems and supports lip moisturising, lip-plumping appearance and lip-repair positioning.
COA specification includes sodium hyaluronate 27-33%, molecular weight 3,000-10,000 Da and melting point 65-80°C.
Usage: Suitable for lipstick, lip balm, lip mask, oil-based makeup, balm, anhydrous stick and other oil-rich cosmetic products.
Mixing method:
- Add into the oil phase.
- Heat to 65-80°C until melted, then mix until evenly dispersed with the oil phase.
- Maintain enough mixing during cooling to keep the dispersion uniform.
Usage rate: 0.5-2%.
Product characteristics: Semi-solid viscous ointment, ivory-white to light yellow.
Solubility: Oil dispersible with heat at 65-80°C; not water soluble as supplied.
Storage: Keep closed in a cool place away from sunlight. For long-term storage, 5-15°C is recommended.

“Closest ingredient-family evidence: 0.1% topical hyaluronic acid creams of different molecular weights significantly improved skin hydration and elasticity versus placebo.”
“Ingredient-family mechanism: hyaluronic acid is a key skin moisture molecule with high water-retention capacity and relevance to skin aging and repair.”
“Closest lip benefit evidence: injectable hyaluronic acid is effective for lip augmentation; supports HA volumizing/plumping concept but not topical oil-dispersed HA microspheres specifically.”
“Closest lip clinical evidence: hyaluronic acid injectable gel improved lip fullness and subject satisfaction for up to 48 weeks; not evidence for topical HA microspheres.”
