Stabiliser, to stabilise the emulsion (co-emulsifier).ĭepending on the type of cosmetic product, the method of application, the area of application or the sensoriality, you will be led to choose different natural waxes.Adhesion agent, to reinforce the adhesion capacity of fats.Thickening, to give consistency to the texture.Emollient, to soften and smooth the skin.Gelling, to make the mixture more viscous and reduce its mobility.Candelilla wax, extracted from a plant that grows in Mexico and southern Mexico Ī wax can fulfil several roles as a texturing agent:.Mimosa wax, extracted from the mimosa flower.Soy wax, obtained by hydrogenation of soybean oil.Carnauba wax, extracted from the leaves of a palm tree, Copernicia cerifera.Rice bran wax, a co-product obtained from the husk of the grain.Other waxes have co-emulsifying properties, and are used in combination with another emulsifier: Several waxes of natural origin have excellent emulsifying properties, and are therefore used in various cosmetic formulations. For example, some waxes are excellent emulsifiers while other waxes are used for their thickening or emollient properties. Not all cosmetic waxes share the same properties. This fundamental trend in cosmetics reinforces the interest of cosmetic brands for quality waxes of natural, vegetal or beeswax origin. Many customers are committed to an eco-responsible approach, which combines well-being, sensoriality and the natural origin of ingredients. 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. Differences between emulsifiers and texturing agentsĬosmetics formulations incorporate emulsifiers and texturing agents at the same time for different and complementary purposes. ![]()
