WebJul 26, 2024 · Griffin in 1949 and its later development in 1954 introduced the HLB system, a semi-empirical method. It is the number on a scale of 1 to 40, as shown in Fig.1. The HLB … WebJan 28, 2024 · The concepts of hydrophilic-lipophilic balance (HLB) and phase inversion temperature (PIT) are both helpful for making emulsions. However, the HLB is a system used help to select PEG-containing emulsifiers by considering their composition—specifically, the percentage of PEG in the molecule.
WebMar 8, 2016 · Griffin’s HLB system was developed for emulsifiers with the structure of amphiphiles, which typically have a hydrophilic (polar) head combined with a hydrophobic (non-polar) tail. It also is possible to have few polar heads and a single non-polar tail, or more complex polymeric structures, but it is difficult to apply the HLB concept. Web(HLB), technical-grade nonionic surfactants. The hydrophile-lipophile balance (HLB) concept was first introduced by Griffin (1) as an empirical scale to describe the balance of the size and strength of the hydrophilic and lipophilic groups in an emusifier molecule. In Griffin’s pro-posed HLB system (1) both surfactants and oil phases could
WebNov 10, 2024 · The balance of the emulsifier is recorded as a number, the HLB value. When this concept was introduced by Griffin , the HLB value of unknown emulsifiers was determined by comparing the emulsification properties in a predetermined system of a mixture of hydrophobic and hydrophilic emulsifiers with a predefined HLB number.
