Carbomer 951 has been investigated as a viscosity-increasing aid in the preparation of multiple emulsion microspheres. Carbomers are also used in cosmetics. Therapeutically, carbomer formulations have proved efficacious in improving symptoms of moderate-to-severe dry eye syndrome. Production Carbomers ...

Compared with other similar polysaccharides, Pullulan's aqueous solution does not have high viscosity. With the increase of the Pullulan molecular weight and concentration, the viscosity of its aqueous solution increases, but the amplitude of increased the viscosity of other polymer substances. The low...
Viscosity:Liquid silicones have viscosity ranging from 300 to 1000 cPs, while gels are over 3500 cPs. Viscosity determines the coating thickness achievable. Hardness:Silicones have Shore A hardness between 20 to 85 after curing. Softer grades are more flexible while harder grades are abrasion resista...
electroluminescence. electroluminescence is an optical phenomenon, and electrical phenomenon where a material emits light in response to an electric current passed through it. as the forward voltage increases, the intensity of the light increases and reaches a maximum. what determines the colour of an...
Define the term radiation buffer used in chemistry. What determines the greatest buffer capacity when looking at solutions? Why will a buffer yield when equal volumes of 0.20M NH3 and 0.10M HCl are mixed? Can sodium chloride and water be used to make a buffer? Explain. ...

for a low temperature application the electrolyte solution will have a lower viscosity compared to one made for a room temperature environment. Lithium salts are essential in the mixture of the electrolyte, the salt determines the conductivity of the solution as well as aids in the formation of ...
The structure level of a carbon black ultimately determines its effects on several important in-rubber properties. Increasing carbon black structure increases modulus, hardness, electrical conductivity, and improves dispersibility of carbon black, but increases compound viscosity. ...
