“Closest exact-family evidence: topical crosslinked resilient hyaluronic acid improved epidermal water retention, reduced TEWL, and improved barrier structure versus linear HA in a 3D human skin explant model.”
Hyaluronic Acid Elastomer (Hyacross Gel, Sodium Hyaluronate Crosspolymer)
Cosmetics
Code: 2230
Ready-to-use Sodium Hyaluronate Crosspolymer gel for long-lasting hydration feel, elastic gel body and soft film formation.
Hyaluronic Acid Elastomer is a ready-to-use Sodium Hyaluronate Crosspolymer gel.
The crosslinked network gives a thicker, more elastic gel feel and forms a soft moisture-retaining film on the skin.
This format is useful when the formula needs long-lasting hydration feel without dissolving powdered hyaluronic acid.
Product Description: The product contains Sodium Hyaluronate Crosspolymer in a water and pentylene glycol carrier. Its high viscosity and crosslinked structure help hold water and create a flexible film that supports a smoother, hydrated after-feel.
COA specification includes clear viscous liquid appearance, pH 5.0-7.5 and dynamic viscosity at 25°C of at least 350,000 mPa.s.
Usage: Suitable for hydrating gels, serums, creams, lotions, masks, sleeping masks, eye gels and barrier-comfort formulas.
Mixing method:
- Add directly into the water phase or cool-down phase and mix until uniform.
- Recommended final formula pH is about 3-8.
- Avoid unnecessary high heat after addition to preserve gel texture.
Usage rate: 1-5%. Typical: 1-3% for hydration feel, 3-5% for stronger gel body and film feel.
Product characteristics: Clear viscous gel/liquid.
Solubility: Water compatible; add directly into water-based systems.
Storage: Keep closed and store refrigerated or in a cool place away from heat and sunlight.

“Ingredient-family evidence: topical 0.1% hyaluronic acid creams significantly improved skin hydration and elasticity; lower-MW HA also improved wrinkle-depth measures after 60 days.”
“Ingredient-family evidence: a single topical fluid containing 1% hyaluronic acid significantly increased skin hydration for 24 hours and reduced TEWL versus untreated control.”
“Ingredient-family evidence: topical hyaluronic acid serum improved facial skin hydration, plumpness, smoothness, fine lines, wrinkles, and overall appearance in a clinical study.”
