The problems: Even when it seems to start working, my mixture often liquifies the moment I remove the source of agitation a hand mixer.
Mostly, I get a slightly viscous fluid that seems semi-stable, though it never progresses past this point, and I can see superfine 'flecks' of oil on the surface of the emulsion. I've tried increasing the initial viscosity with the addition of tapioca starch, but this isn't yielding adequate results.
I'm using the wrong surfactant. I want a 'natural' emulsifier that's also easy to understand on product labels, so lecithin seemed a good fit. I'm overdoing the lecithin is using too much of a surfactant something to worry about? The hand blender is applying the wrong kind of shear sometimes I get better results making, say, mayo using a whisk.
The MCT is not viscous enough to start the process off. I can see hints of this in the way the oil 'takes'; it seems less enthusiastic, shall I say, to incorporate itself. I'm barking up the wrong tree entirely.
Either way, I know this should work, and I've seen it almost work. I just don't know what I'm doing wrong, because isolating the variables is hard when it's not possible to isolate a certain variable beyond certainty a hand blender; I mean, c'mon. Optional reading: First off, I'm super new at this. I'm not a chemist. I have a rudimentary knowledge of emulsification: partitioning of immiscible liquids in shells of surfactants surrounded by a continuous medium; the higher the intermolecular impact velocity the better right?
Anyway, help would be immensely appreciated! Tagged: emulsion. Belassi Member. December edited December Probably the first item is your hand blender. Almost all of them are low-shear because the cup wall is too far away from the blade tips.Glycerin, also known as glycerine and glycerol, is a natural alcohol derived from the animal or vegetable fats used in the soap-making process.
Commercially available as an emollient in toiletries and cosmetics, glycerin is also a preservative in foods.Water, Oil and Alcohol
With a viscous, or syruplike, consistency, glycerin's colorless, sweet and odorless properties make it a relatively safe and versatile ingredient for making your own laundry detergents, soaps and lotions or extending the life of beauty products.
Mixed with water, glycerin can be used as a homemade natural hair and scalp moisturizer. Measure glycerin and distilled water at a ratio anywhere between 1-to-4 and 1-to-1, one at a time. These ratios are recommended for best consistency for use in the spray bottle. Measure 2. If needed, adjust ratios after using the mixture depending on the hair's texture and reaction. Pour distilled water into the bottle, followed by glycerin. The glycerin should try to settle on the bottom of the bottle because it is viscous.
Shake the bottle for 10 seconds until the solution is homogeneous. Glycerin is water- and alcohol-soluble, so it will dilute easily. For mixtures with a higher amount of glycerin, shake longer until it dissolves completely. Add a few drops of essential oil s for added benefits to scalp or fragrance such as lavender or jojoba. Find pure vegetable glycerin or glycerol at Henry's Marketplace, Whole Foods and Michaels craft stores.
Using a ratio heavy on the glycerin will make the solution tougher to dissolve and may not spray as well. Video of the Day. References PioneerThinking. Homemade Glycerin Moisturizer. Vegetable Glycerin Uses. How to Make a Beeswax Emulsifier. Glycerin for Hair Growth.

Where Does Panthenol Come From?There are two types of emulsifiers: Lipophilic and Hydrophilic. Lipophilic emulsifiers combine with post emulsifiable oil- based penetrants. The resultant emulsifier-penetrant combination can be removed from a part surface by water spray. The lipophilic emulsifier works primarily by diffusion into the post emulsifiable penetrant. Lipophilic emulsifiers are supplied in a ready to use form by the manufacturer. No pre-rinse step takes place. After the penetrant dwell time is completed, lipophilic emulsifier is usually applied by dip, and then the lipophilic emulsifier drains from the parts.
The emulsification and drain step is timed to prevent over emulsification and possible removal of penetrant from discontinuities. Parts go through a water rinse immediately after the emulsification time.
Hydrophilic emulsifiers are supplied as a concentrate. Hydrophilic emulsifiers work by detergent action. After the penetrant dwell time, parts are pre-rinsed with water before application of the hydrophilic emulsifier. Parts are immersed in a mildly agitated tank of hydrophilic emulsifier. Hydrophilic emulsifier may also be applied to parts by spray. With spray application of hydrophilic emulsifier, the pre-rinse step is usually omitted.
The hydrophilic emulsification step is followed by a final water rinse. Submit a blog topic idea. A brief overview of the 4 advantages of using a petroleum suspension vehicle bath to protect your magnetic particle wet bench investment.

The interfacial tension between the internal and external phases must be lowered to allow for the formation of droplets. These surfactants SURFace ACTive AgeNTS have a lypophllic oil-loving tail that can partition or line up into the oil droplet phase while their hydrophilic water-loving heads line up into the water phase.
Their tail should be at least 14 carbons long for them to be considered "good" emulsifiers, as opposed to surfactants only. Thus, all emulsifiers can be considered to be surfactants, but not all surfactants are emulsifiers in the cosmetic sense of the word. Surfactants are characterized according to the "balance" between the hydrophilic "water-loving" and lipophilic "oil-loving" portions of their molecules.
The hydrophilic-lipophilic balance HLB number indicates the polarity of the molecules in an arbitrary range ofwith the most commonly used emulsifiers having a value between 1 and The HLB number increases with increasing hydrophilicity. According to the HLB number, surfactants may be utilized for different purposes:. HLB Range. Antifoaming agent. Emulsifier, water-in-oil.

Emulsifiers are also used as aerating agents to make desserts such as mousses and cakes -- and as crystallisation inhibitors, to avoid the formation of white patches on chocolates.
Common emulsifiers include lecithin, mono and diglycerides, glycerides, monoglyceride derivatives, and fatty acid derivatives. Extracted from vegetable oils such as soy and sunflower oil, lecithin has been used as a food emulsifiers since the s. The number In Canada, lecithin is the equivalent of L. Lecithin is used in a wide range of food products, including margarine, chocolate, breads and cakes, bubble gum, salad dressings and sauces. Mono and diglycerides, as well as their purified form distilled monoglycerides, are the oldest and most common food emulsifiers.
These emulsifiers are produced by mixing edible oils with glycerin, and widely used in bakery and dairy products, and margarine. On the label of food products, mono and diglycerides correspond to the number In Europe, the number E identify these emulsifiers. The combination of monoglycerides with other substances produces emulsifiers with specialized function called monoglyceride derivatives.
For instance, ethoxylated monoglycerides are the result of the interaction between a monoglyceride and ethylene oxide. Other monoglyceride derivatives include acetoglycerides They are common cake emulsifiers, because they increase the aeration of the dough.
Polyglycerol esters PGEpropylene glycol esters PGMSstearoyl lactylates, sucrose esters, sorbitan esters and polysorbates are the most common food emulsifiers derived from fatty acids. Stearoyl lactylates are used as dough strengtheners and conditioners in breads, while sorbitan and polysorbates are used for aeration in cakes and icings.
Sucrose esters are also used in bubble gum, sauces, soups and canned liquid coffee. By: Yasmin Zinni. Number of Calories in Chocolate Mousse Cake.Cancel an order through the website. Cancel an item or through the website.

Glycerin is a hygroscopic ingredient, which means that it draws, and holds, water.
Glycerin may be petro derived so it's important that it be purchased knowing whether it is vegetable, or petro, derived, if that's important to your product philosophy. Vegetable Glycerin, is used in personal care products to make the skin draw water, from the environment, binding it to the skin, where glycerin serves as hydration, binding moisture to the skin, to make it more smooth and soft.Wiz khalifa wife
Care should be taken, when using Vegetable Glycerin, because if glycerin is used in a dry climate it may draw moisture from the tissues. Vegetable Glycerin, is also highly used in the extraction of botanicals where glycerin improves the extraction, acting as a, weak, water solvent.

Overview; Glycerin, or glycerol, is a 3-carbon sugar alcohol that forms the backbone to which fatty acids are attached in the fats known as triglycerides. Lecithin is a fat also known as phosphatidyl choline. It is based on a glycerol backbone.
In lecithin, two of glycerol's carbons are attached to fatty acids and the third is attached through a phosphate group to choline. Vegetable glycerin is derived from vegetable oilsas opposed to glycerin derived from animal fats or petroleum products.
It is considered a carbohydrate and has similar calories per gram as table sugar. However, it has very little effect on blood sugar or insulin levels in healthy people, according to a article in the journal " Diabetes. Uses of Glycerine. Glycerin sweetens and thickens food products and may act as a preservative. It helps retain moisture both in foods and in skin lotions. According to the Food and Drug Administration, vegetable lecithin comes from the processing of soybean, corn and safflower oils, with most of it coming from soybeans.
Lecithin makes a good emulsifier because its fatty acids are oil-soluble while the choline phosphate is water-soluble. This dual character makes it a key component of cell membranes in plants and animals.
In foods, lecithin acts as an emulsifier and as a releasing agent, preventing sticking. It also helps prevent spattering during frying.
