Sodium Hyaluronate, cosmetic grade, >1500 kDaUsage: Dissolving in water. Heating can accelerate the dissolution of Sodium Hyaluronate.Functions: Lubricating and film-forming, moisturizing, preventing skin damage, thickening and keeping emulsion stab.Application: Skin care: cream, emulsion, essence, lotion, gel, facial mask, etc.Makeup: lipstick, eye shadow, foundation, etc.Cleansing: facial cleaner, body wash, etcHair care: shampoo, hair conditioner, styling gel, hair restorer, etc.High molecular weight sodium hyaluronate: water-retaining, forming a permeable mesh hydration film on the skin surfaceLow molecular weight sodium hyaluronate: nourishing, softening cuticle, nourishing and repairing skin surfaceUltra-low molecular sodium hyaluronate: transdermal absorption, water storage, deep moisturizing, free radical elimination, anti-agingUtilizing the moisturizing properties of different molecular weight sodium hyaluronate in different skin layers, obtain the best combination and ratio, make skin moist and soft from inside to outside.Proper use of Sodium HyaluronateSodium hyaluronate has good compatibility, and can be added into almost any water-containing cosmetics. Its high molecular and high-viscosity properties make it dissolve relatively slow. The higher the molecular weight and the higher the concentration, the slower it can be dissolved.Recommended dissolution methods:1. Heat water to 60°C-80°C, slowly add sodium hyaluronate under rapid stirring to make it completely dispersed and fully swelled. Continue to stir it for 20 minutes to 60 minutes so it can be completely dissolved.2. Add a proper amount of glycerol into the container with sodium hyaluronate. Shake or stir it to make sodium hyaluronate completely soaked. Slowly add 60°C-80 ° C water while stirring, stir until completely dissolved.3. Add high molecular weight sodium hyaluronate to a solvent such as glycerin, propylene glycol or 1,3-butanediol, stir and mix, then add to the aqueous phase, stir it until completely dissolved.Attention:1, Sodium hyaluronate should be dissolved in pure water or distilled water, in order to guarantee the fine transparency.2, Sodium hyaluronate is a high-nutrient substance and easy to be contaminated by microorganisms. Once dissolved, try to use it up at one time. If there is residual liquid, please store it with preservative to avoid microbial pollution. Choose preservatives for normal use. Can not be mixed with cationic surfactants or cationic preservatives to avoid turbidity or precipitation reactions.
