What is the HLB of glyceryl stearate?
For this example, we’ll use Glyceryl Stearate [HLB = 3.8 ± 1] and Ceteareth-20 [HLB = 15.2 ± 1].
What is the HLB value for detergent?
The HLB of the nonionic surfactant is set to be between 13 and 16 which is the standard HLB range for detergent products (Griffin, 1949) and to ensure that the product exhibits high detergency and forms a clear solution (Fung et al., 2007).
What is HLB value of surfactants?
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.
What is HLB method?
Hydrophile Lipophile Balance (HLB) is a way of measuring a substances solubility within water or oil. The HLB system was created as a tool to make it easier to use nonionic surfactants. The HLB system enables you to assign a HLB value to a surfactant and a HLB requirement to the application for that surfactant.
How is HLB calculated?
Using the following equation: HLB desired = ( % surfactant A ) × ( HLB Surfactant A ) + ( % surfactant B ) × ( HLB Surfactant B . ) A blend of surfactant A, HLB = 7.8, and surfactant B, HLB = 13.4 produces a combination that is water soluble and contributes other desired properties.
What is the HLB value of castor oil?
Comparing the castor oil-water emulsion with methanol-castor oil-water emulsion, the optimal hydrophilic and lipophilic balance (HLB) value based on castor oil-water system was acquired between 6.6 and 7.5, while the optimal HLB value based on the methanol-castor oil-water system was between 5.5 and 6.0.
What is HLB What is HLB value of Acacia?
The hydrophile-lipophile balance (HLB) of acacia has been determined in the presence of various ethylene oxide derivatives of sorbitan fatty acid esters. A revised HLB value of 11.87 for acacia has been proposed.
