For example, the Spans® generally have low HLB numbers and they are also oil soluble. Low HLB emulsifier's are soluble in oil and give rise to water in oil emulsions. DUROSOFT® PG4-O, is an effective emulsifier/co-emulsifier that is cold-processable. Emulsifiers & Stabilisers E400-E495. If an emulsifier has a low HLB number, there is a low number of hydrophilic groups on the molecule and it will have more of a lipophilic character. They show low stability at high temperatures, they do not react with shale rapidly neither with hydration nor dehydration, and they are also of high viscosity at ambient temperatures. I recently came across this article dismissing HLB for organic/ natural cosmetics and suggesting that 'Anyone who encourages you to calculate the HLB of your emulsifiers will be mainly used to working with synthetic emulsifiers'. Bancroft's rule suggests that the type of emulsion is dictated by the emulsifier and that the emulsifier should be soluble in the continuous phase. 6 ACC AE-914N C-911 Narrow range surfactant with great. DA: 98 PA: 8 MOZ Rank: 56. h ly tsied to non-ic s,. Emulsifiers (Surfactants) Span 80 (Sorbitan monooleate), HLB 4. In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin to reduce viscosity. Sorbitan Stearate is a non-ionic low HLB emulsifier (4. The lower the HLB, the more lipophilic or fat soluble the emulsifier becomes. HLB Description Emulsifiers IMWITOR® 600 Polyglyceryl-3 Polyricinoleate 2–4 4 IMWITOR® 600 is a powerful W/O emulsifier that is used to form W/O emulsions with excellent stability even with high water content. Potassium cetyl phosphate is primarily used as a co-emulsifier with low HLB non-ionics. THE HLB SYSTEM A TIME SAVING GUIDE TO SURFACTANT SELEC. 03: Excellent emulsifier, wetting agent, stabilizer, couples detergent range nonionics into hydrocarbon systems. Lipophilic (oil-soluble, low HLB) surfactants are used to stabilize w/o emulsions, whereas hydrophilic (water-soluble, high HLB) surfactants are used to stabilize o/w systems In these emulsions within emulsions any drug. sucrose ester high HLB surfactants and citrate or sorbitan ester low HLB surfactants. • Low HLB emulsifiers are soluble in oil. Excellent oil-soluble surfactant, low HLB emulsifier. Total number of registered articles: 3,641,839 2,034 journals (3,002,861 articles), 238 proceedings. Monday, 1 March 1999 higher polar emulsifiers (HLB > 12) provide the formation and then stabilize direct emulsions, lower polar (HLB < 6) are suitable for reverse emulsions. Contact Oxiteno for more information about our ALKEST® TW line of mild, non-ionic polysorbates. These low HLB emulsifiers are generally used in conjunction with polysorbates (ethoxylated sorbitan ester) for functionality in whipped toppings, ice creams, icings, fillings and chocolate, as well as emulsified shortenings. The lotion containing 6% of the sunflower-derived emulsifier increased skin hydration up to 1. More specifically, by heating the water phase to above the melting point of the low HLB co-emulsifier, the fatty chains of the co-emulsifier parallel each other, forming a bilayer structure—i. ,Ltd (Primitive name: Liuzhou Gaotong Food Chemicals Co. Definition low HLB values ranging from 1. Fat feeding in poultry is greatly overlooked in spite of having its high nutrient value not only as a source of energy but its role in metabolic and immune system functions. 99734 ? 09 ? 5 manufactured by Rhodia. Traditionally emulsions are prepared using two surfactants; one with low HLB and one with high HLB. (HLB 13), 9. • High HLB emulsifiers are soluble in water. Different types of emulsifiers are commercially available. They are sorbitan esters based on various fatty acids. Demulsifier additive chemical to oilfield water/oil emulsion alters the kinetic stability by changing the interfacial film encapsulating the water droplets allowing the coalescence of the water droplets separate from the. As a result of their oil soluble character, they will cause the oil phase to. Choosing the Cosmetic Emulsifier - Questions to ask your Supplier 5 HLB? 6 Optimum oil phase concentration? 8 Needs an stabilizer/ a co-emulsifier?. For a particular organic contaminant, optimum aqueous phase solubilization will generally occur at a specific HLB number. Alone, it is an excellent solubilizer of essential oils, a wetting agent, viscosity modifier, stabilizer and dispersing agent. Natural Emulsifier HE20 is a versatile non-ionic natural emulsifier designed for low viscosity and sprayable formulations. HLB Values of Surface Active Agents In general, the emulsifiers with low HLB values will tends to promote the formation of water-in-oil emulsions and those with high HLB values will form oil-in-water emulsions. Find emulsifier companies that can design, engineer, and manufacture emulsifier to your companies specifications. Emulsifiers. HallStar ® BST-COS is a low viscosity, low color and low odor emollient ester. Offering samples freely, we warmly welcome to buy our products made in China and enjoy our low price. 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. The two dominant factors that were found to affect the stability of multiple emulsions in high HLB surfactant systems are the osmotic pressure imbalance between the internal aqueous phase and the external aqueous phase, and the adsorption/desorption characteristics of the emulsifier/surfactant film at the oil/water interface. Its oil solubility makes it a very effective coupling agent and co-emulsifier for mineral oil. It forms highly stable emulsions with excellent appearance and feel, compatible with a wide range of ingredients and pH. The low-HLB surfactant is dominantly hydrophobic and is added to the oil phase. But it makes more sense for silicones to have a required HLB value of 5. Dow Corning claims that its new water-in-oil emulsifier provides expanded options for formulating stable PEG-free water-in-oil and water-in-silicone emulsions, for use in the cosmetics industry. HLB value is the measure of degree of lipophilic or hydrophilic. At high pH values we will have oil-in-water emulsion [3]. 8 Propylene Glycol Isostearate HLB = 2. It imparts a light smooth feel to skin and its broad co-solubility make it useful as an emollient in a wide variety of personal care products.
