The water retention of cellulose is affected by many factors, including viscosity, addition amount, thermogelation temperature, particle size, degree of crosslinking, and active ingredients.
Viscosity: The higher the viscosity of cellulose ether, the stronger its water retention capacity. This is because cellulose ether with high viscosity can better hinder the loss of water molecules.
Addition amount: As the amount of cellulose ether added increases, its water retention will also increase. This is because more cellulose can form a denser network structure, which can better retain water.
Thermogelation temperature: Within a certain range, the higher the thermogelation temperature, the higher the water retention rate of cellulose ether. This is because high temperature can make cellulose molecules swell and disperse better, thereby enhancing its water retention capacity.
Particle size: Smaller particle size can improve the water retention of cellulose because smaller particles can provide a larger surface area, which helps to enhance the interaction between molecules.
Degree of crosslinking: The degree of crosslinking of cellulose also affects its water retention. The higher the degree of crosslinking, the stronger the interaction between cellulose molecules, which can form a more stable and dense network structure, thereby improving water retention.
Active ingredients: Active ingredients in cellulose, such as soluble substances and polysaccharides, also affect its water retention. These active ingredients can interact with cellulose molecules, thereby changing its water retention properties.
