“Closest ingredient-family evidence: topical multi-molecular-weight HA creams improved skin hydration and elasticity; 50 and 130 kDa HA significantly reduced wrinkle-depth measures after 60 days.”
17D Hyaluronic Acid (High Concentrate / High Viscosity)
Cosmetics
Code: 126129
High-viscosity 17D multi-hyaluronic gel combining multiple HA molecular sizes and derivatives for premium intensive hydration formulas.
17D Hyaluronic Acid (High Concentrate / High Viscosity) is a concentrated multi-hyaluronic gel designed for premium water-based hydration formulas.
The system combines multiple HA molecular weights and HA derivatives so formulators can build surface hydration, lightweight low-molecular hydration, improved skin affinity, cationic substantivity and longer-lasting moisture film in one ingredient.
Product Description: 17D Hyaluronic Acid contains a 17D HA system. The table below separates the HA types by molecular-size fraction or derivative form for easier formulation review.

| 7 | Hydrolyzed Hyaluronic Acid | Small molecule 50-100k Daltons | Small-to-medium hydration bridge. |
| 8 | Hydrolyzed Hyaluronic Acid | Medium molecule 100-500k Daltons | Mid-range hydration and slip. |
| 9 | Hydrolyzed Hyaluronic Acid | Medium molecule 500-800k Daltons | Mid-to-high molecular weight water binding. |
| 10 | Sodium Hyaluronate | Medium molecule 0.8-1.5M Daltons | Surface hydration and film feel. |
| 11 | Sodium Hyaluronate | Large molecule 1.5-1.8M Daltons Large molecule 1.8-3.0M Daltons | Higher surface film and moisture-retention feel. |
| 12 | Hydroxypropyltrimonium Hyaluronate | Cationic Hyaluronic Acid | Improves substantivity on skin and hair. |
| 13 | Sodium Hyaluronate Crosspolymer | Cross-polymer type | Moisture-retaining HA network. |
| 14 | Sodium Acetylated Hyaluronate | Acetylated type | Improves skin affinity and soft moisturized feel. |
| 15 | Ascorbyl Propyl Hyaluronate | Vitamin C hyaluronate derivative | HA derivative carrying vitamin C functionality. |

| 17 | Zinc Hydrolyzed Hyaluronate | Zinc hyaluronate derivative | HA derivative carrying zinc functionality. |
It has a gel texture, is easy to use, and can be mixed into water formulas immediately.
Recommended concentration of Hyaluronic Acid 17D
Very dry skin 10-20%
Dry skin 5-10%
Normal or general dehydrated skin 2-5%
(Not suitable for direct use on skin because it is highly concentrated. Dilute in a formula or in water only.)
Usage: Suitable for all types of hydrating cosmetics, including gel, serum, lotion and cream formats.
Mixing method: Mix directly into the water phase of the formula. The finished formula should have pH in the range of 3-9.
Usage rate: 1-20%. Please refer to the appropriate concentration for each skin type above.
Product characteristics: Thick, cloudy gel texture.
Solubility: Water soluble; disperses directly into water-based formulas.
Storage: For long-term storage, keep refrigerated and avoid sunlight and heat. Shelf life is at least 2 years.
