Potassium Hyaluronate And Its Uses
Potassium Hyaluronate and Its Uses
Sodium Hyaluronate Crosspolymer is an ultra-high molecular weight polymer obtained from sodium hyaluronate through cross-linking reaction, which has a dense reticular structure. The cross-linking reaction makes the HA macromolecules highly aggregated and folded locally, which can bind more water molecules and form a long-lasting bio-protective film on the surface of the skin, which is silky and elastic, and has the functions of locking, storing, isolating and protecting water. It can be used as a free radical scavenger to reduce pain and blisters after sun exposure; it can be applied to cosmetics and hair products; and it can also be used as a delivery system for water-soluble or oil-soluble active substances. After cross-linking, hyaluronic acid not only increases its relative molecular mass, but also increases its volume, thus forming a reticular structure; the morphology is transformed from a sol to a gel, and its own structure and function are strengthened.
Acetylated sodium hyaluronate is obtained by acetylation of sodium hyaluronate and has the following effects:
①Highly "skin-absorbent": It has excellent skin affinity and adheres firmly to the skin, providing long-lasting moisturising and skin-softening effects.
② double moisturising power: can play a double moisturising ability, but also a short period of time to quickly combine water, increase the water content of the skin, so that the skin continues to moisturise for 12 hours.
③ Repair skin barrier: not only promotes the proliferation of epidermal cells, but also repairs damaged epidermal cells, enhances the barrier function of the epidermal stratum corneum, and improves the skin's natural resistance.
Hydroxypropyltrimethylammonium chloride hyaluronate is a cationised hyaluronic acid. In addition to the moisturising properties of hyaluronic acid, it also has good adsorption and affinity to the skin and hair, is not easy to be rinsed off, and can play a long-lasting and efficient role in nourishing and moisturising the skin. As a moisturising factor in shampoos and conditioners, it has a good conditioning effect, enhances skin moisturising efficiency, reduces irritation, and is compatible with cationic, non-ionic, anionic and amphoteric systems.
Potassium hyaluronate is relatively rare on the market, but the patent information - "A potassium hyaluronate and its use" - shows that its effects are as follows:
①Potassium hyaluronate has anti-ageing effect on the skin, it can resist oxidation, effectively improve the state of aged or new aged skin, and maintain the youthfulness of the skin.
(ii) Potassium hyaluronate has obvious protection and repairing effect on the damage produced by ultraviolet rays, and can effectively resist the skin photo-aging caused by ultraviolet rays, and is suitable for sunscreen or post-sunscreen repair.
③Potassium hyaluronate has the effect of removing skin wrinkles, and is suitable for the restoration of skin wrinkles due to aging on the face, eye corners or other parts of the skin.
Hyaluronic Acid & Silanetriol, e.g. EPIDERMOSIL, unlike regular hyaluronic acid, EPIDERMOSIL is a combination of hyaluronic acid + silanol with a synergistic effect: hyaluronic acid stabilises the active silicon core and maintains the activity of the silicon, which in turn enhances the activity of the hyaluronic acid. And due to the high affinity of silicon to dermal tissue, silanols bring better skin distribution of hyaluronic acid.
In addition, low molecular hyaluronic acid triggers a virtuous cycle by binding to the CD44 receptor (a class of transmembrane glycoproteins, the most important hyaluronic acid receptor on the cell surface) on the surface of basal layer keratinocytes: the receptor CD44 on the surface of keratinocytes is overexpressed by binding to hyaluronic acid, the expression prompts keratinocytes to proliferate, and more keratinocytes produce natural hyaluronic acid after the proliferation.
A complex of high molecular weight hyaluronic acid and bentonite clay has been introduced to the market, which effectively traps the high molecular weight hyaluronic acid molecules in the interstitial spaces of the specific layered structure of the bentonite clay through activation of the bentonite clay. When using products containing the hyaluronic acid and bentonite clay complex, the hyaluronic acid molecules are electrically attracted to the deeper layers of the skin and penetrate up to 75 microns, providing a good anti-aging effect, long-lasting moisturisation and a matte finish.
