The table below lists HLB values along with typical performance properties. The higher the HLB value, the more water-soluble the surfactant. The 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. Often, a process of further trial and error is the only way to find the best ‘chemical-type’ of surfactant. Cosmet. What are spans and tweens? The er ctant HLB value, the more c it is. <> Select your oil phase and determine its Required HLB from the table.4 Listed in Table 1 are some approximations for the HLB value for surfactants as a function of their solubility in water. The Spans and Tweens are a range of mild nonionic surfactants providing formulating benefits in a number of Home Care applications. The characteristics of surfactants containing mainly fatty acid-alkanolamine-monoderivative, ester or amide are shown in Table 2. A multipronged approach works best. The HLB value of the emulsifier system that "works best," under your own trial conditions, is the "Required HLB" for your set of ingredients.Even if all the required HLB values of your ingredients are published in Table 5A, it is still a good idea to run this experimental determination, because oils, waxes and solvents from various sources vary in properties and emulsifying characteristics. Of course, there are additional approaches to stabilizing emulsions, such as thickening the external phase with a rheology modifier like carbomer or a hydrophobically modified analog. 992 0 obj trailer Some HLB values. <<07FD425AD21DB2110A000B016021F4FF>]/Prev 150539>> endobj Two series of nonionic surfactants were studied by different HLB methods (conventional-, ... factants used in the measurements are given in Table 1. 0000001027 00000 n 87%. 991 0 obj Step 1: Determine the HLB requirement of the oil.

For example, if we were to make an oil-in-water emulsion containing palm oil, we would start with our specified quantity of water, and then add the desired amount of palm oil (e.g., 10% (w/w)). There is a balance between hydrophilic and lipophilic parts The HLB value is what the HLB Predictor calculates and it is a logP-like property indicating the lipophilicity and water solubility of the compound. Table 16.3 indicates the HLB values of common emulsifiers. G. BEN-ET D. TATARSKY Center for Industrial Research Food Institute What are spans and tweens? Select the node information types that you want to include in your query. NMR thus provides a convenient method for rapid HLB determination of polyethoxylated nonionic surfactants, even if no prior knowledge of sample composi- tion is available. Hydrophilic-lipophilic balance (HLB) system enables to choose proper surfactant with ease. Chlorinated Paraffin … 20% X Required HLB 14 = 2.8 A method is presented for the determination of HLB values and required‐HLB values. • The HLB Value that works best under your trial conditions is the Required HLB for your set of ingredients. Griffin's method for non-ionic surfactants as described in 1954 works as follows: 0000001663 00000 n A change in conductivity or in the DC results in a deviation from the reference value in percent, determined during the reference phase. Step 3: Determine surfactant concentration … endobj These two initial steps will narrow the field of potential emulsifiers significantly. All these surfactants, co-surfactant and oils are generally accepted as safe, nonirritant and nontoxic for use in a number of pharmaceutical, cosmetic, and food products (18).

Chem., 5, 249-256 (1954). In this example, the blended HLB value would be 10. above table of nonionic HLB values and applications, it would appear that the appropriate multiplier for the SMA® products may be about 2.8. <>stream The HLB scale is very relative scale; the number values of the HLB Scale don't necessarily give insight into the properties of a surfactant, just their relative hydrophilicity compared to other surfactants. The HLB value of a surfactant blend is the weighted average of HLBs of the individual surfactants. The table below lists HLB valuesalong with typical performance properties. The That said, the HLB Scale is widely used in industry. The HLB system is not without its limitations, yet it remains a good place to start. HLB scale showing classification of surfactant function The hydrophilic-lipophilic balance of a surfactant is a measure of the degree to which it is hydrophilic or lipophilic, determined by calculating values for the different regions of the molecule, as described by Griffin in 1949 and 1954. One is lipophilic (sorbitan stearate) and the other hydrophilic (polysorbate 20). EFFECT OF DIFFERENT HLB VALUE AND ENZYMATIC TREATMENT ON THE PROPERTIES OF OLD NEWSPAPER DEINKED PULP ... Also, Table 2 shows that tear index of treated pulps with combination of commercial cellulase and lipase at both temperatures produced a pulp with 6.0 mN.m2g-1 compared with 5.3 mN.m2g-1 for the control pulp. By their very nature all surfactants (surface active agents) are amphiphilic. HLB (Hydrophile-Lipophile Balance) is an empirical expression for the relationship of the hydrophilic ("water-loving") and hydrophobic ("water-hating") groups of a surfactant. Energy digestibility is estimated using prediction equations specific for each feed material and then used to estimate net energy values. Step 2: Determine the most effective surfactant chemistry. <> 14 – 100%. The required HLB of an oil phase mixture can be calculated by first calculating the percent of the oil phase each ingredient contributes. 1006 0 obj Thanks. This data from HLB-positive mature trees suggested that (1) the detection rate for Liberibacter in leaves using TXCChlb is comparable to that with HLBaspr, (2) both HLBaspr and TXCChlb are more sensitive than CQULA, and (3) detection from root tissue using TXCChlb is more consistent than from leaves tested with HLBaspr.

[/ICCBased 1002 0 R] In addition the values depend on temperature and salinity which for this table can be assumed to be 25° and "low" respectively. 52%. HLB is short for hydrophilic-lipophilic balance. We are using the generic term "hydrocarbon" to designate the oil soluble portion of the molecule. It has a backbone of glycerol that bonds up to three other molecules. A class of sucrose esters with highly substituted hydroxyl groups, olestra, is also used as a fat replacer in food. This means that their molecular structure has both a polar, water-loving group and a non-polar moiety, such as a hydrocarbon alkyl chain, with greater affinity for oil. S: Number of ester saponification A: Acid number of the fatty acid The HLB values of some of the most frequently used surfactants are shown in Table 11.1. endobj The HLB values assigned to nonionic surfactants ranges between 0.5 (most lipophilic) and 19.5 (most hydrophilic). 72%. Sucrose monostearate History. Therefore, study of HLB system is very important. Briefly, it turns out that both of the latter two mechanism are not correlated to the HLB, thus proving that this parameter alone could easily result to be an inaccurate predictor of the effects of the emulsifier on the gelato structure. 0000002404 00000 n The INRAE-CIRAD-AFZ feed tables contain chemical data, nutritional data and environmental data of feeds for ruminants, pigs, poultry, rabbits, horses and fish (salmonids). This difference is most likely due to the fact that the values reported in the literature are based on a calculated HLB number using the equation 1 and not from the conventional (experimental) method. Tweens are polyoxyethylene derivatives of spans. 0000002680 00000 n Correspondingly, what is lecithin and what is an emulsifier? The hydrophilic strength of a nonionic surfactant is calculated on a molecular weight basis. HLB is a global network of independent advisory and accounting firms.

Comparison of ARs obtained using this column with those obtained with PS-DVB sorbents modified by polar groups (Strata-X and Oasis HLB) (Table 5) shows how important in the extraction process are bonding forces other than Π-Π, for example, dipole-dipole and induced dipole-dipole bonding. It is also important to keep in mind that cosmetic emulsions often have complex oil phases with several components. They were obtained by hydrodistillation and several emulsions were prepared by changing emulsifi ers. %PDF-1.4 %âãÏÓ The Three Step Surfactant Selection Method. Broadly speaking the data show that for ionics the head group doesn't make a big difference and that the cmc decreases steadily (in a log fashion) for longer chain lengths and that cmc is simply estimated via molar volume. The required HLB of our oil phase is the sum of these numbers or 7.85 Let's make the Oil Phase more complex. Highly water-soluble surfactants are best for cleansing while surfactants with intermediate solubility in water are best for oil-in-water (o/w) emulsions. High concentrations of high HLB surfactants are needed to break up dispersed oil droplets to create more thermodynamically stable microemulsions. 10. All Rights Reserved.

The HLB system enables you to assign a HLB value to a surfactant and a HLB requirement to the application for that surfactant. Different oily phase need a different value of HLB surfactant so that the most stable emulsion can be formed. 0000002872 00000 n The HLB system enables you to assign a HLB value to a surfactant and a HLB requirement to the application for that surfactant. HLB; According to Griffin, the amphiphilic molecule is the value obtained by dividing the weight percentage of the hydrophilic part by five. Further, it also provides the distinction of surfactants application based on their HLB values. <>stream Through the power of 27,485 professionals across 153 countries, we combine local expertise and global capabilities to service your needs. The Required HLB of the oil is equal to the calculated HLB value of the binary blend of emulsifiers that provides the most stable and aesthetically pleasing emulsion. We would then use blends of the emulsifiers at specified ratios (e.g., see Table 2) to prepare a series of formulations, ultimately allowing us to select the correct ratio of emulsifiers in the final system based on stability, physical appearance, and other factors. An emulsion is a system of two (or more) immiscible materials (usually liquids) in which one material (the dispersed/internal phase) is suspended or dispersed throughout another material (the continuous/external phase) in separate droplets. They include values about more than 200 feeds of plant and animal origin and 100 mineral sources. 0000002470 00000 n The length of the alkyl chain influences the CMC and HLB value and these become important considerations when selecting the right ‘chemical-type’ for your emulsion. <> For the emulsifiers, a good starting place would be to have a total concentration equal to that of the palm oil.
