This is the place to find tips for the beauty professional that may be beyond what your average consumer needs to know.
A great resource for those that do need it. Ingredients are important but the emulsifier is actually the key. An emulsion is a mixture of water and oil. There are 2 basic types of emulsions:. The level of greasiness depends on the formula - all of which will be absorbed into the skin.
The emulsion is usually made with your choice of oil, beeswax, borax and water. If done correctly you will have little to no greasiness. This method creates cream and lotions that feel moist, less greasy. When absorbed into the skin there is very little to no oily residue. There is only one truly undisputed natural emulsifier. Too much beeswax and you get this glob that is only good for your notes on what not to do.
It takes some investigative work to determine the source and extraction methods. If you ask what is this made of; you will almost always find that it is at least partially plant based. As the handcrafter you must then ask how was this extracted?
For instance Stearic Acid is derived from plants; however, the method used to extract the substance leaves little left that offers any benefit to the skin. Listed below are some of the common emulsifiers that are in use today. There are many more that are reaching the market everyday such as Ultramaize, and others. If you have questions on emulsifiers try www. Angie is a sweetheart full of information and will answer all of your questions. She will also let you know what is a synthetic as well as what is natural.
Borax or sodium borate is a naturally occurring alkaline mineral first discovered over years ago. Borax alone will not emulsify. It must be used in conjunction with Beeswax. Together the electricity from the friction of the two causes the reaction and yields an emulsion.
Beeswax - The honey bee, Apis Mellifera, secretes beeswax to build the walls of the honeycomb and when secreted the wax is a transparent colorless liquid, which turns into a semi-solid substance on contact with the atmosphere. Beeswax also known as Cera alba and Cera flava is used in cosmetic and skincare products as a thickening agent, emulsifier, and humectant and has emollient, soothing and softening properties and helps the skin retain moisture.
Only when used incorrectly in cosmetic formulations can beeswax cause a problem with clogging of pores, but used the way that our scientists have included it in the products used, it only brings the positive properties of healing, antiseptic, emollient and softening to the formulations.Emulsions are stabilized by adding an emulsifier or emulsifying agents.
These agents have both a hydrophilic and a lipophilic part in their chemical structure. All emulsifying agents concentrate at and are adsorbed onto the oil:water interface to provide a protective barrier around the dispersed droplets. In addition to this protective barrier, emulsifiers stabilize the emulsion by reducing the interfacial tension of the system.
Some agents enhance stability by imparting a charge on the droplet surface thus reducing the physical contact between the droplets and decreasing the potential for coalescence. Emulsifying agents can be classified according to: 1 chemical structure; or 2 mechanism of action. Classes according to chemical structure are synthetic, natural, finely dispersed solids, and auxiliary agents.
Classes according to mechanism of action are monomolecular, multimolecular, and solid particle films. Regardless of their classification, all emulsifying agents must be chemically stable in the system, inert and chemically non-reactive with other emulsion components, and nontoxic and nonirritant.
They should also be reasonably odorless and not cost prohibitive. The Pharmaceutics and Compounding Laboratory. Emulsifying Agents Emulsions are stabilized by adding an emulsifier or emulsifying agents.A variety of emulsifiers are natural products derived from plant or animal tissue. Most of the emulsifiers form hydrated lyophilic colloids called hydrocolloids that form multimolecular layers around emulsion droplets.
Hydrocolloid type emulsifiers have little or no effect on interfacial tension, but exert a protective colloid effect, reducing the potential for coalescence, by:. Naturally occurring plant hydrocolloids have the advantages of being inexpensive, easy to handle, and nontoxic. Their disadvantages are that they require relatively large quantities to be effective as emulsifiers, and they are subject to microbial growth and thus their formulations require a preservative.
Lecithin and cholesterol form a monomolecular layer around the emulsion droplet instead of the typically multimolecular layers. Animal derivatives are more likely to cause allergic reactions and are subject to microbial growth and rancidity.
Semi-synthetic agents are stronger emulsifiers, are nontoxic, and are less subject to microbial growth.
List of Emulsifying Agents
Synthetic hydrocolloids are the strongest emulsifiers, are nontoxic, and do not support microbial growth. However, their cost may be prohibitive. The Pharmaceutics and Compounding Laboratory. Natural Emulsifying Agents A variety of emulsifiers are natural products derived from plant or animal tissue.
Hydrocolloid type emulsifiers have little or no effect on interfacial tension, but exert a protective colloid effect, reducing the potential for coalescence, by: providing a protective sheath around the droplets imparting a charge to the dispersed droplets so that they repel each other swelling to increase the viscosity of the system so that droplets are less likely to merge Hydrocolloid emulsifiers may be classified as: vegetable derivatives, e.So many of you want to make natural or organic creams and lotions, and for that there is one essential ingredient needed: a natural and organic emulsifier for cosmetics.
Would you rather download this guide and learn about natural preservatives too? Then click below for your free guide! A cream or lotion contains an oil phase and a water phase. As oil and water do not naturally mix together, in order to make a cream or lotion an emulsifier is needed. Emulsifiers contain a hydrophilic element water loving and lipophilic element oil loving.
This means they are attracted to both oil and water, which allows them to bind the two together to form a stable mixture. Note that beeswax is not a emulsifier; it will not create stable emulsions. We have included the INCI name along with the trade name under which it is sold. When searching for these ingredients online, use the INCI name as they may be sold under a few different trade names.
Perfect for rich cream textures which are non-greasy. Very suitable for anti-aging or very hydrating creams. Another easy-to-use emulsifier which creates smooth and creamy emulsions. Very versatile, as it helps create a wide range of textures — from milks to heavy creams depending on dosage used. Works in an ideal pH range of Important note: ECOMulse is anionic therefore it is recommended that it should not be used with ingredients that do not mix well with anionic ingredients.
This emulsifier is derived from natural olive chemistry. It is an emulsifier and thickener in one which is compatible with a wide variety of cosmetic and active ingredients over a wide pH range 3 to Safe and clinically tested to be hypoallergenic, it provides creams with an excellent moisturizing effect and spreadability with a creamy, non-oily, cool touch.
Ideal for wrinkle care for both eye contour and face, as it is very moisturizing. Discover the most natural emulsifiers and preservatives for your skincare products by downloading our free guide!

Skincare products on the market typically use synthetic emulsifiers, but natural emulsifiers are available for whipping up homemade lotions and potions. Beeswax has been used in skin care for centuries.
It has softening and healing properties on its own but also works well as a thickener and emulsifier. It's best used in oil-in-water emulsions, though it can make a base for creams when used along with other emulsifiers. Beeswax is great for formulas designed to absorb quickly. For a plant-based and allergy-free wax emulsifier, there's candelilla wax.
It comes from the wild Mexican candelilla plant, which forms the wax on the outside of its leaves to protect it from water loss. While most waxes are best suited for lighter formulations, candelilla works well in thicker, heavier, water-in-oil formulations.
Lotions made with candelilla wax sit on the skin longer without breaking down, making them great for drier or sensitive skin that need more protection. This fatty phospholipid mixture is a perennial favorite of DIYers thanks to its versatility and ease of use.
Lecithin is found in a wide variety of plant and animal products, including soybeans, rapeseed, corn, and egg whites. Lecithin typically combines best with oil but is highly effective in water-based emulsions as well. It's humectant, meaning it draws moisture from the air and deposits it on the skin, and also helps ingredients penetrate better—ideal for anti-aging products for drier, more mature skin.
Derived from African acacia tree sap, acacia gum can be found in many forms, including thick gel, liquid, and powder. It has its own soothing and anti-inflammatory properties. Acacia is added to the water in oil-in-water emulsions, so it's ideal for the lightest formulations. For thicker creams, combine it with another emulsifier. Video of the Day.

For example, when oil and water are combined, they will eventually separate into two layers if left to their own devices. An emulsifying agent has stabilizing properties that distribute oil and water molecules evenly throughout the mixture to prevent separation.
Emulsification is used to make food more visually appealing and to improve taste and texture. Monoglycerides are a combination of glycerol and fatty acids. According to UnderstandingFoodAdditives. Lecithin, a monoglyceride often found in egg yolks, is frequently used as an emulsifier.
Animal fat and vegetable oil can be used to produce artificial emulsifying agents. Emulsifying agents also come in different strengths depending on the size of their molecular structures.
An emulsifier with a large molecular size, such as the diacetyl tartaric esters of monoglycerides used in bread, are more potent than those with smaller molecular structures. Emulsifying agents are able to prevent the separation of oil and water due to their unique molecular structure.
Quick guide to natural and organic emulsifiers for cosmetics
One end of the molecule is hydrophilic, or attracted to water. The other end of the molecule is lipophilic, or attracted to oil. Since each end of the molecule is attracted to one of the two main substances in the mixture, emulsifying agents evenly distribute throughout the water and oil rather than forming a separate third layer. The emulsifiers also keep the oil and water evenly distributed, preventing them from forming separate layers of their own.
Some food products are commonly used as emulsifying agents. According to Food Network, milk, eggs, mustard and gelatin can be added to oil and water mixtures to emulsify them. Mixtures can be emulsified by hand by adding an emulsifying agent into a water-based mixture, then slowly pouring in oil while vigorously stirring.
The continued motion ensures the emulsifying agent evenly distributes through the mixture to prevent the oil and water from separating. Oil-based salad dressings such as Caesar dressing and mayonnaise often require this technique. Emulsifying agents are one of the most common additives in processed foods.
Low-fat margarine spread relies heavily on added emulsifying agents.
