propylene glycol hlb value

01 02 1982The empirical hydrophile-liophile balance (HLB) value of nonionic surfactants is an important parameter used to predict performance as e g emulsifiers solubilizers and wetting agents However the HLB value is based on an original molecular structure and does not take into account all the factors affecting the performance of nonionics such as presence of additives type of solvent The HLB value is 13 It complies with FDA 21CFR 175 105 175 300 176 170 176 180 More Surfadol 541PG Wetting Agent for Metalworking Fluids Surfadol 541PG is a liquid preparation of 2 4 7 9-Tetramethyl-5-decyne-4 7-diol in 50% Propylene glycol It can reduce dynamic surface tension and break the bubbles compatible with other surfactants or defoamers More News Center Notice of

Propylene glycol alginate containes up to 36% propylene glycol On the assumption that all of this amount is hydrolyzed and taking into account the ADI of 0-25 mg/kg by for propylene glycol the Committee allocated an ADI of 0-70 mg/kg bw (100/36 x 25) to propylene glycol alginate The Committee was aware of new toxicological studies on propylene glycol but as the compound was

Was ist Propylene Glycol? Propylene Glycol werden die unterschiedlichsten Eigenschaften zugeschrieben Doch was ist richtig? So wird zum Beispiel verbreitet dass Propylene Glycol vielfltige Bilder allergischer Hautreaktionen hervorrufen kann und dass es durch das Einschleusen durch die Haut zu Nierenschden und Leberanomalien kommen

ing propylene oxide butylene oxide nitrogen or sulphur exhibit a behavior which has not been related to their composition For these products an experimental method must be used Greenwald et al 5 proposed that the titration by water of a dioxane-benzene solution of an oil or a surface active agent to a cloud end point can be used to determine a value related to the hydrophile-lipophile

numerical value which we call its HLB The HLB of ICI emulsifiers is shown in all current ICI emulsifier literature and similar values may be calculated or estimated by various means for any emulsifier Methods for determining this HLB value are discussed in Chapter 7 The HLB of an emulsifier is an expression of its Hydrophile-Lipophile Balance i e the balance of the size and strength of

tri- and higher esters giving a wider range of HLB-values (from 1 to 16) than can be obtained with any other polyol-derived surfactant This is particularly valuable to formulators as it offers a wide range of high HLB non-ionic and PEG-free surfactants The relation between sucrose ester grade mono-ester content and HLB value is shown in

The HLB value of the emulsion with the least dispersion ratio or the least percentage increase in mean droplet diameter was taken as the required HLB of the respective essential oil The turbidimetric method was validated by the existence of correlation (r = ?0 958) between the mean droplet diameter and the turbidity of the emulsions The turbidity curve went through a maximum at the HLB value

Surfactants are typically amphiphilic molecules that contain both hydrophilic and lipophilic groups The hydrophile-lipophile balance (HLB) number is used as a measure of the ratio of these groups It is a value between 0-60 defining the affinity of a surfactant for water or oil HLB numbers are calculated for nonionic surfactants and these surfactants have numbers ranging from 0-20

prepared by polymerization of ethylene oxide propylene oxide and butylene oxide in the same molecule Depending on the ratio and order of oxide addition together with the number of carbon atoms which vary the chemical and physical properties nonionic surfactant is used as a wetting agent a detergent or an emulsifier HLB (Hydrophilic-Lipophilic Balance) values for proper applications

In a second process step more water containing a hydrophilic emulsifier having a higher HLB value preferably in the range from 12 to 25 is added to the primary emulsion until phase inversion occurs It is important that the procedure in this second process step is not reversed i e that the primary emulsion is not added to the aqueous phase Further active substances such as UV filters and
