The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipophilic portions of the surfactant molecule, as described by Griffin in 1949 [1][2] and 1954. [3] .

Hydrophilic–lipophilic balance (HLB) is the balance of the size and strength of the hydrophilic and lipophilic moieties of a surfactant molecule. The HLB scale ranges from 0 to 20. In the range of 3.5 to 6.0, surfactants are more suitable for use in W/O emulsions.

2024年4月16日 · HLB was developed into a semi-empirical model by Griffin in 1949 and its development in 1954. It is a number on a scale of 1-40 (see Figure 1). Based on the HLB value, the surfactant is classified as water-soluble or oil-soluble according to its relative solubility.

2024年2月23日 · The Hydrophilic-Lipophilic Balance (HLB) scale is a foundational concept in the design and formulation of surfactants and emulsifiers. Its application spans diverse industries, influencing the stability, texture, and performance of emulsions in products ranging from cosmetics to pharmaceuticals.

The HLB system is a numerical scale developed by William Griffin in the 1940s to classify emulsifiers based on their balance between hydrophilic (water-attracting) and lipophilic (oil-attracting) properties. This balance, typically represented on a scale from 0 to 20, determines the surfactant's emulsifying capabilities.

... very useful numerical rating scheme, known as the hydrophilic-lipophilic balance (HLB) number, was introduced by Griffin (12). In this empirical method, sur- factants are assigned a number...

2020年4月27日 · HLB is an arbitrary scale that indicates the extent of hydrophilic lipophilic balance (HLB). Surfactants such as Spans (sorbitan ester) are Lipophilic and have low HLB values (1.8 to 8.6). On the other hand, Tweens (polyoxyethylene derivatives of Spans) are hydrophilic and have high HLB values (9.6 to 16.7).

2022年12月30日 · I am trying to use the HBL scale to find the correct emulsifiers for both creams and lotions. Can I calculate the best emulsifier by using the scale for products between 20-45% creams and lotions? What am I looking at when buying emulsifiers?

HLB values ranging from 1.8 to 8.6. HLB value for W/O emulsion. blends of high and low HLB surfactants can be used to obtain the required HLB of an oil.

2021年7月13日 · Hydrophilic–Lipophilic Balance Concept: The HLB concept was introduced by Griffin in 1947 to classify nonionic surfactants but has since been applied to ionic surfactants as well. In this system, each surfactant is assigned a number between 1 and 20, representing the relative proportions of lipophilic and hydrophilic parts of the molecule.
