Physiological Functions
Sodium Hyaluronate is a major component of intercellular substances and distributes in other tissues widely. Sodium hyaluronate is the sodium salt of hyaluronic acid. Hyaluronic acid is found naturally in the fluid that bathes joints, in the vitreous humor of the eye and in the skin. It's abundant in the dermis of young skin, but levels of this important compound decline with age. This makes skin look olderin and is usually well tolerated even by people with sensitive skin.
The main physiological functions an follows:
1)Wound healing
2)Anti-sunburn and repair the injured skin 3)Protection against infection
4)Control of electrolytes and water in extracellular fluids 5)Lubrication
6)Maintenance of stable transparent fluid in the eye
Water Holding Capacity
The water holding capacity of Sodium Hyaluronate isextremely high compared to other moisturizers Moisture retention of moisturizers ?at *5? ,*0%relative humidity,**0min.After application?
Water Retention
The chart on the right illustrates that the moisture evaporation rateconstant of Sodium Hyaluronate is less than that of other moisturizers.This indicates that it possesses strong water retention properties.
Water Uptake (Hygroscopic property?
As shown in the figure,the water uptake of Sodium Hyaluronate is exteemely high compared to other moisturizers under the relative humidity *3%,but lowest water uptake under relative humidity *5%.Despite changes in external humidity ,it is capable of maintaining the constant moisture.
Skin Slip Resistance
Sodium Hyaluronate?s low skin slip resistance maintains excellent skin lubricity as shown on the right.
