On the hydrophilic-lipophilic balance value of surfactants
All things in the world have affinity between water and oil. In today's discussion of surfactants, the key lies in the hydrophilic-lipophilic balance value (HLB).
The surfactant can change the interfacial properties, and its molecules have both ends of hydrophilic and lipophilic. HLB value is the standard for measuring its hydrophilic-lipophilic degree. Those with low value, the lipophilic is better, and it is often suitable for non-aqueous systems. It can be used as a defoaming and emulsifying aid to make oil droplets disperse in non-aqueous media, stable but not polymerized. High value, hydrophilic strong, mostly used in water systems, can help water-soluble substances, increase its dispersion, washing, solubilization work is significant, so that oil melts in water, descaling net.
emulsifier, according to HLB selection, oil phase is different, need to adapt the HLB value, can form a stable emulsion. Another example is solubilizer, high HLB value active agent must be selected, so that insoluble substances have a place in water.
View this HLB value, in the application of surfactants, such as the rudder of a boat, lead it on the right path. In this way, the use of active agents can be made good, in daily chemical and chemical industries, and can achieve all kinds of effects, benefiting the world.
