Ultra low molecular sodium hyaluronate

What ultra low molecular sodium hyaluronate is

Sodium hyaluronate is the salt form of hyaluronic acid, the well-known humectant. The ultra low molecular grade on this page consists of very short chains, so short that, as our product record puts it, the resulting solution is almost like water. That makes it very different from the long-chain grades that form thick gels. The powder is sold by the gram. The record also notes that it dissolves slowly, so plan a little extra mixing time. The exact molecular weight and INCI are on the CoA.

Properties

Very short chains give a light, non-sticky hydrating feel and leave no visible film, which suits face mists, toners, hair sprays and makeup removers. Because viscosity stays low, you can add it to almost any water-based product without reformulating the texture. Brands often use it next to long-chain hyaluronic acid to describe multi-level hydration, and the ultra low label signals that the product is designed for a weightless finish.

Applications

The record lists shampoos, balms, masks, creams, tonics, hair cosmetics, sprays, face care, makeup removers, baby cosmetics, after-shave products, eye cosmetics and fluids. That breadth reflects how easy the ingredient is to use. Pair it with Low Molecular Weight Hyaluronic Acid 10-20 kDa and Hyaluronic acid liquid 1% for a three-weight hydration product. More humectants are listed in our cosmetic actives catalog.

How to dissolve and add it

Sprinkle the powder slowly onto the surface of water while stirring, or premix it with glycerin to wet it first. Keep stirring until the solution is fully clear, which can take some time. Add the solution to the water phase or during cool-down. Avoid intensive, prolonged heating. Follow the CoA for the use level; very short-chain grades are usually used at fractions of a percent.

Ideas for gentle products

Baby care, after-shave and eye products all call for mild bases. Combine the ingredient with panthenol, allantoin and glycerin, leave out fragrance where possible and select a preservative suitable for the audience. In micellar makeup removers, add it after the surfactants for a softer after-feel. In after-shave balms, it adds a fresh, hydrated finish without stickiness.

Compatibility

The powder is compatible with glycerin, panthenol, niacinamide, peptides, plant extracts, mild surfactants and nonionic emulsifiers. Strong acids, oxidizers and enzymes can degrade hyaluronic acid. Cationic conditioning agents may interact, so test clarity in hair products. Add it at the end in surfactant systems.

Characteristics

Form: powder. Solubility per our record: dissolves slowly in water; the solution is almost as thin as water. Uses per our record: hair and face care, sprays, makeup removers, baby care, after-shave, eye care. Molecular weight and INCI: on the CoA.

Original recipe: soothing after-shave fluid, 100 g

Phase A: distilled water 87.60 g, glycerin 3.00 g, panthenol 1.50 g, allantoin 0.20 g. Sprinkle in Ultra low molecular sodium hyaluronate 0.20 g and stir until clear. Phase B: caprylic/capric triglyceride 3.00 g, sodium acrylates copolymer and lecithin 1.50 g; stir into An until a light fluid forms. Phase C below 40 °C: bisabolol 0.20 g, preservative 1.00 g, fragrance 0.30 g, aloe vera juice 1.50 g. Mix and adjust pH to about 5.5.

Record the lot number of Ultra low molecular sodium hyaluronate in your batch log so every production run can be traced back to its certificate of analysis.

Record the lot number in your batch log so every production run can be traced back to its certificate of analysis. Retain a small sample of each lot for at least the shelf life of the finished product, since it makes later quality questions much easier to answer.

Storage

Keep the powder sealed in a cool, dry place away from humidity. Close the container right after use, since hyaluronic powders absorb moisture. Ships from Florida in gram packs.
