What Represents Medium Molecular Weight Hyaluronic Acid
Medium Molecular Weight Hyaluronic Acid 1 g is a white powder form of Sodium Hyaluronate with medium molecular mass of at least up to 130 kDa. This ingredient belongs to the Anti-Age Actives section and is supplied in a 1 gram container suitable for small scale formulation testing and home cosmetic production.
Main Properties
The powder is fully soluble in water and shows pH values between 4.0 and 6.0 when dissolved. It combines surface moisture retention with moderate penetration into upper epidermal layers, delivering balanced hydration without excessive viscosity build up in finished products.
Applications in Cosmetic Formulations
This raw material is used in moisturizing serums and lotions at 0.3 percent, eye area care at 0.25 to 1 percent, lip balms and makeup removers at 0.25 to 2 percent, pre and post solarium cosmetics at 0.5 to 1 percent, body modeling serums at 1 to 2 percent, and early skin recovery preparations at 0.5 to 2 percent. It also appears in hair care sprays, conditioners and body lotions where water retention without heavy feel is required. Related options can be found in the Hyaluronic Acid catalog.
How to Introduce into Formulations
Add the powder to the aqueous phase at the final stage of emulsion preparation once the batch temperature falls below 40 degrees Celsius. Typical working concentration ranges from 0.1 to 1 percent of total product weight. First disperse the powder in distilled or deionized water at room temperature, allow it to swell for several hours with occasional stirring until a smooth solution forms, then incorporate into the cooled base.
Compatibility with Other Actives
The medium fraction pairs well with low molecular weight and high molecular weight hyaluronic acid variants to create layered hydration effects. It integrates smoothly into water based systems alongside humectants and soothing agents while maintaining clarity in transparent gels. Additional moisturizing options are listed under Moisturizing Actives.
Appearance and Characteristics
The product is supplied as a white powder in a transport container. It remains stable when stored away from moisture and light, with an indicated shelf life until 12.2028 under proper conditions.
Storage Conditions
Keep the powder in a cool, dry place protected from direct light and humidity. The material is hygroscopic, therefore the container must stay tightly closed after each use to preserve its functional properties.
Example Application or Recipe
Light Moisturizing Facial Serum. Distilled water 90 ml, Medium Molecular Weight Hyaluronic Acid 0.5 g, Vegetable glycerin 5 ml, Panthenol 2 ml, Broad spectrum preservative 1.5 ml, Aloe vera extract 3 ml. In a separate vessel dissolve the hyaluronic acid powder in cold distilled water and leave to swell for 3 to 4 hours, stirring periodically until fully dissolved without lumps. Next add glycerin, panthenol and aloe extract while mixing at low speed to avoid foam formation. Finally incorporate the preservative, stir thoroughly and transfer the finished serum into a sterilized bottle with a dispenser. Store in a cool place away from direct sunlight.
FAQ
Is this hyaluronic acid suitable for transparent gel formulas?
Yes, the medium molecular weight fraction dissolves in water to produce clear solutions that suit transparent cosmetic gels and serums.
What temperature limit applies during production?
The ingredient must be added only after the batch cools below 40 degrees Celsius to avoid polymer chain degradation.
Can different molecular weights be combined in one formula?
Yes, the medium fraction works well together with low and high molecular weight hyaluronic acids to achieve multi level hydration.
How long does the swelled solution remain stable before use?
Prepare the solution fresh for each batch and incorporate it promptly into the final product to maintain optimal performance.
