However there are more than 1 oil used in Oil Phase. 0000001257 00000 n Lower HLB values indicate a more lipophilic emulsifier, whereas higher values indicate a more hydrophilic emulsifier. 0000004194 00000 n 0000001865 00000 n As for books on cosmetic emulsifiers, try the Allured index or buy Perry's starter book. Summary of HLB ranges and their applications. The combination of emulsifiers is usually comprised of emulsifier of high HLB and low HLB allowing good anchoring in both water phase ( high HLB ) and oil phase ( low HLB) improving stability. PEG-150 Stearate (HLB ~ 12) comes to mind, and not much of it. 0000000656 00000 n 0000014684 00000 n Calculate the HLB value of your oil phase; Match it to the HLB Values of the Surfactant. An example of an emulsifier with a high HLB value is polysorbate 80 which is used to control fat agglomeration in ice cream and whipped toppings. 0000003999 00000 n The number refers to # parts of ethylene oxide, which can be contaminated with. Chemical emulsifiers, which are made of some of the same molecule chains that give natural emulsifiers their properties, are the most frequently used in processed foods. Benefits of natural oils for face, body and hair, Notes on acids referenced in natural oils chart, Tips for choosing and combining natural oils, A chart of essential oils organized by skin type, Appendix I – Combining Essential with Carrier Oils. All natural fatty tissue found in plants and animals. Natural fatty acid found in plants and animals (found in animal fat, cocoa butter and vegetable fats such as palms). To sum up, the HLB value alone is a significant factor when comparing groups but, in general, is not correlated to destabilization when considering emulsifiers of the same family. and low HLB values (1.8-8.6). • The value of HLB ranges from 1- 20. startxref In general, emulsifiers with HLB-values of 3 – 8 give w/o-emulsions, whereas those with values of above 9 are more water-soluble and result in o/w-emulsions. Steareth-21 contribution 0.3x 15.5 = 4.65. I'd use a higher HLB co-emulsifier if you decide to increase that oil load. These emulsifiers are phospholipids. Emulsifiers with low HLB values are more oil-soluble (lipophilic), while those with higher values are more water-soluble (hydrophilic). Synthetic polymer, the number corresponds to the amount of ethylene oxide, Derived from the fatty acids in coconut oil and monoethanolamine (MEA), an organic chemical compound with an, All natural, derived from glycerin (animal or palm kernel/soy/vegetable fat) and lauric acid (often found in coconuts), All natural, derived from glycerin (animal or palm kernel/soy/vegetable fat) and stearate (a salt derived from either animal or vegetable fat), All natural, the 'SE' refers to "self-emulsifying" (contain both o/w and w/o emulsifiers), which is the 3-6% of potassium stearate (potassium salt of stearic acid), Chemical compound that combines stearic acid (derived from animal or vegetable fat) with ethylene glycol (organic compound, toxic if ingested, used to keep product from melting in high temperatures); produces pearlescent effects like bath gel, foaming. The assigned values range from 1 to 20. Emulsifiers may be added to milk to prevent separating and extend its shelf life. The required HLB for an oil is the HLB value of the surfactant that will provide the lowest interfacial tension between your oil phase and your water phase. Contact BAAST.ca to contribute edits. In order to form stable emulsions, an emulsifier or emulsifier mixture having HLB value equal to the HLB value of the oil phase should be used. Similar to Calcium Stearoyl Lactylate - combines lactic acid & stearic acid (all natural), then reacts with sodium or calcium hydroxide (a manufactured substance also known as lye) to make a sodium or calcium salt. Emulsifiers with low HLB-values are more lipophilic (bind oils), while higher HLB compounds are hydrophilic (bind water). In order to match the HLB of a particular oil phase, it is easiest to set up a spreadsheet with the calculation and vary the percentages of each emulsifier in increments of 5% to find the right ratio. 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 when all the required HLB values of your ingredients are published in Table 2A, 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. 0000421429 00000 n HLB - Hydrophilic-Lipophilic Balance Calculator for Emulsions : Calculate the Total HLB of a mixture of components Enter the % proportion of the component and its HLB value (leave remaining rows as 0) Composed of sorbitol (a sugar alcohol obtained from glucose) and stearic acid (animal or vegetable fatty acid), has thickening properties, improves water resistance (good for sun screen), Three ester groups of oleic acid and sorbitol, soft skin feel (can be animal or vegetable source), Three ester groups of stearic acid and sorbitol (can be animal or vegetable source), A mixture of ethanolamides (organic chemical compound) of stearic acid, foam booster, used to increase thickness. HLB values below 7 indicate emulsifiers that are more soluble in oil and HLB values above 7 indicate emulsifiers that are more soluble in water. Low HLB values emulsifiers are associated with high oil solubility which is useful when formulating of water-in-oil (W/O) emulsions such as margarine. Note: This chart is a guide not an authority. 114 18 For example, vegetable oil emulsions need an emulsifier with an HLB of 7–8, whereas the required HLB value to form a stable castor oil emulsion is 14. Not much oil to emulsify there either. HLB Value is a System designed to help you chose which surfactant or … For example, if I wanted to emulsify Soybean Oil, which has a required HLB of7, I would need to use an emulsifier or blend of emulsifiers that had a HLB of 7 ± 1. Mixture of methyl glucoside (a sugar derived from glucose in a lab) and stearic acid (natural fatty acid found in plants and animals). Cetearyl is formed from the condensation of cetearyl alcohol. It is easily soluble in water, soluble in ethanol, vegetable oil, ethyl acetate, methanol, and insoluble in mineral oil. found naturally in fruits and berries, or can be produced synthetically, A synthetic surfactant and emulsifier based on sorbitol and modified oleic acid, (Almost) all natural (see sodium stearoyl lactylate) but may or may not be considered vegan; derived from stearic and lactic acids; used to create a smooth, oily feeling to cosmetics, Ceteareth is a natural fatty acid derived from coconut oil. HLB value: 15.0. HLB numbers allow the ability of the surfactant to stabilise o/w or w/o emulsions to be predicted. xref %%EOF The values range from 0 to 20, but some emulsifiers have been shown experimentally to have higher values. Tweens, which are polyoxyethylene derivatives of spans, are hydrophilic and have high HLB values (9.6-16.7). These observations on preferred HLB range apply only to nonionic emulsifiers and anionic/nonionic emulsifier blends, which were the emulsifier types screened in the present investigation. Waxy solid used as a thickener/hardener in cosmetics. I'll leave the HLB math up to you. All natural fatty tissue found in plants and animals. Most commonly available at nutrition store from sunflowers or soya. The HLB value can be used to predict the surfactant properties of a molecule: < 10 : Lipid-soluble (water-insoluble) > 10 : Water-soluble (lipid-insoluble) 1 to 3: anti-foaming agent; 3 to 6: W/O (water in oil) emulsifier; 7 to 9: wetting and spreading agent; 13 to 16: detergent; 8 to 16: O/W (oil in water) emulsifier 0000325653 00000 n In addition to being outstanding emulsifiers, these emulsifiers provide unique solubility, liquidity and outstanding feel when applied to the skin, making them highly desirable in cosmetic emulsions. 1$��kXl[*�.�P�5�Cpcg"9 *X�X�'H��O��!�c``/ ��x����:�`hh8�*�PJ�ABJ �LuJ`#P�J�%--�*&����M@\q�b8b D�����TBáj���F,��II5��Z��0�A�U5��bM�m��� J ����N�)�咚u�t��|����^���������A��y˕���B4�M`������ֆ�F�|��v0. To … The HLB number increases with increasing hydrophilicity. How to find which Surfactant/Emulsifier to use using HLB Method. Emulsifiers with HLB numbers in the 3–6 range are best for w/o emulsions, whereas emulsifiers with HLB numbers in … All natural. 0000001323 00000 n Lecithin and lysolecithin are vastly used and one of the most efficient emulsifier. The HLB value varies from 0 to 40. 114 0 obj <> endobj Tween-80 is light yellow to amber oily viscose liquid, non-toxic. Stearic acid is used as a thickener/hardener in cosmetics. It is widely accepted that the best emulsifier pairings are formed when a high HLB emulsifier is combined with an emulsifier with a low HLB rather than just selecting the emulsifier with the exact HLB you want to achieve. 131 0 obj <>stream 0000001641 00000 n Quick Test for an … (d) determine the HLB requirements for the food system – involves screening emulsifiers over a range of HLB values & several concentrations to determine approximate requirements – then verify through experimentation 8.5.
