Physiological
Functions Sodium Hyaluronate
is a major component of intercellular substances and distributes in
other tissues widely.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.
