Low Molecular Sodium Hyaluronate

Sodium hyaluronate behaves very differently depending on chain length. Long chains make thick, silky gels; short chains give thin, watery solutions with a quick-absorbing feel. Low Molecular Sodium Hyaluronate is the short-chain end of the family, chosen when a product must stay light and free of stickiness while still carrying the hyaluronic acid name.

What low molecular means

The molecular weight of a hyaluronic acid grade describes the average chain length. Lower values mean shorter chains and lower viscosity at the same concentration. On skin, lower weight grades tend to feel less tacky and leave little visible film. The precise molecular weight range for our lot is printed on the CoA, and it is worth recording in your formula sheet because it influences texture.

Supplied form

We sell this grade as a dry material by weight. The solubility field on our product page uses a generic liquid template; in practice the material is hydrated in water before being added to a formula. A short-chain grade usually hydrates faster than a high molecular one, but it still benefits from careful dispersion.

Applications

The supplier specification covers a wide range: serums, balms, masks, creams, toners, hair cosmetics, sprays, facial care, makeup removers, baby cosmetics, moisturizing products, eye cosmetics, fluids and appearance-focused cosmetic compositions.

Thin textures

Toners, essences and mists benefit most. They stay watery and sprayable even with a meaningful hyaluronic level.

Eye gels

Low viscosity and low tack make it comfortable for the eye contour, where heavy films can feel tight.

Multi-weight systems

Combining low and high molecular weight hyaluronic acid gives both a surface film and a lighter, quick-absorbing component in one product.

Preparation method

Sprinkle the material slowly onto the surface of stirred water, or disperse it first in glycerin and then add water. Let it hydrate until the solution is completely clear and free of gel particles. Add the solution to the water phase or to the cooled emulsion. Strong acids, high electrolyte loads and long high-shear mixing can affect hyaluronic polymers, so check the finished product over time.

Partner ingredients

A simple humectant base with glycerin and betaine supports the hydration claim. For an amphiphilic partner with a lasting soft finish, add sodium acetylated hyaluronate. Further moisture ingredients are listed under actives.

Writing about it honestly

Hyaluronic acid copy often promises far more than a moisture ingredient can deliver. Stay with what can be measured on the finished product: hydration, a smoother surface, plumper-looking fine dry lines and comfort. Avoid suggestions that it changes the structure of the skin.

Quality control

Hyaluronic acid grades can vary slightly from lot to lot in viscosity and molecular weight. Record both values from the CoA, prepare a small test solution on arrival and compare its clarity and flow with the previous lot. If a product suddenly feels thinner or stickier, this record makes the cause easy to find. Microbial safety matters too: prepared solutions without preservative support growth quickly, so preserve stock solutions and use them within a short period. Clean, dry scoops and fast closing of the pack keep the material free flowing over its shelf life.

Original recipe: airy eye gel, 100 g

Purified water 91.30 g, glycerin 2.00 g, low molecular sodium hyaluronate 0.30 g, high molecular sodium hyaluronate 0.10 g, carbomer 0.40 g, sodium hydroxide solution 0.40 g, caffeine 0.50 g, panthenol 1.00 g, propanediol 3.00 g, eye-safe preservative 1.00 g. Disperse the hyaluronates in glycerin and propanediol, add water and hydrate. Disperse carbomer, dissolve caffeine and panthenol, add preservative and neutralize to pH 6.0.

Storage

Store tightly sealed in a cool, dry place. Close the pack immediately after weighing to keep moisture out.
