Plant sources (carnauba, jojoba, candelilla, olive, etc.).Mineral sources (mainly petrochemical).They can be extracted from three main sources: Waxes have been known for thousands of years for their cosmetic properties. Cosmetic waxes, emulsifiers or texturing agents For example, a shampoo will favour a texturing agent with foaming properties, while a cream will favour a texturing agent with emollient properties. Application performance (sensoriality, spreadability, etc.).Įach type of cosmetic product meets specific expectations.Rheological characteristics (viscosity, smoothness, etc.).Structure (active ingredients, excipients, additives including emulsifiers, etc.).Texturing agents make it possible to obtain all the expected qualities: However, it is not sufficient on its own to formulate a cosmetic product that meets the expectations of consumers. The emulsifier is essential because it ensures the stability of an emulsion. The emulsifier, at the oil/water interface, thus plays the role of a “link” between the two phases and brings a certain stability and homogeneity to the emulsion. The hydrophilic part turns to the aqueous phase, while the hydrophobic part turns to the lipid phase. One part is hydrophilic and attracts water, while the other part is hydrophobic and repels water. To boost the stability of an emulsion and insure an optimal sensoriality and texture, adding an emulsifier in the formula is mandatory.Īn emulsifying molecule has very particular characteristics: it is amphiphilic and bipolar at the same time. Thus, your product will be unbalanced and will lose a (huge) part of its properties. The fatty substance, which is lighter, will rise to the surface. However, the aqueous phase and the lipid phase are not miscible and will separate quickly. a lipid phase, which contains an oil or a fat and fat-soluble components.an aqueous phase, which contains water and water-soluble components.
Creams, shampoos, hair care products, sunscreens, make-up, face care products and baby lotions are most of the time made up of several elements: Obligatory emulsifiers in cosmeticsĬosmetics are principally emulsions. The high-pressure homogenizer has a very high shearing power and can adjust fine particle emulsions.Įven a small amount of emulsifier can be used to adjust the emulsion, without adversely affecting, for example, the water repelling properties, waterproofing, or heating stability, and without compromising the function of the base wax.Differences between emulsifiers and texturing agentsĬosmetics formulations incorporate emulsifiers and texturing agents at the same time for different and complementary purposes. Emulsification equipmentĪ general manufacturing process for wax emulsion involves pouring hot water into an emulsifying tank and then adding melted wax from a wax dissolving tank while stirring to create a preliminary emulsion.Įmulsifier should be added at the appropriate time.Īfter that, the particle size of the emulsion is adjusted using a high-pressure homogenizer, and the emulsion is cooled using a plate chiller and removed. In this way, selecting the appropriate emulsifier enables applications including mold release agents, polish, ceramic binders, powder metallurgy, lubricants, rust inhibitors, water repellents (including for food packaging), and paint additives. In addition, the dried film has excellent barrier properties and base material wettability.
On the other hand, if a nonionic emulsifier is used, excellent mixing stability with various other emulsions can be achieved. It is important to select the appropriate emulsifier according to the type of wax and application.įor example, the anionic emulsifiers we use have excellent water repelling properties in the dried film due to the use of alkaline components that evaporate with moisture. Relationship between emulsifiers and fields of useĮmulsifiers have both hydrophilic groups that have an affinity for water and oleophilic groups that have an affinity for wax.
