Emulsions in cosmetics - what is behind the popular water and oil mixture

What are emulsions?

Below you will learn what emulsions are, which is an emulsion, which types of emulsions there are and what advantages they have. The most popular and best-known emulsions in cosmetics include creams, lotions, fluids and body milk.

the mixture of water and oil

emulsions are a system (or a mixture) consisting of two different liquids, one of which diffuses in the form of small droplets by the other, as in the mixture of water and oil.

emulsifiers, are tools that connect these two liquids that otherwise do not mix. Everyone knows it, oil floats on water and even if you are stirring and shaken the oil, the oil is back on the water surface after a short time. Emulsifiers connect the oil to the water phase and creates a milky consistency, which is liquid or creamy or creamy depending on the oil or water content.

emulsions are often used in the cosmetics industry as they are an excellent way to donate the skin moisture and protection. Whether natural cosmetics, biocosmetics or homemade cosmetics, emulsions can be found everywhere.

Types of emulsions in cosmetics

A simple emulsions consists of an aqueous phase, an oil phase and an emulsifier.

Depending on the chemical nature of the emulsion, oil-in-water (O / W), water-in-oil (W / O), water- in silicone (w / s) or silicone-in-water (si / w) emulsions.

oil-in-water emulsions (O / W)

oil-in-water emulsions are systems in which oil droplets are dispersed in the water.

They are most commonly used in cosmetics as they are suitable for making creams and lotions for all skin types. In addition, they are more lighter in their haptics, are somewhat liquid and pulling quickly.

water-in-oil emulsions (w / o)

Water-in-oil emulsions are systems where water droplets are dispersed in oil.

They give thicker and denser creams that are ideal for dry skin. Mostly they do not pull them as fast and leave a rather greasy feeling on the skin.

water-in-silicone emulsions (w / s)

water-in-silicone emulsions are systems where water droplets are dispersed in silicone.

silicone-in-water emulsions (si / w)

Water-in-silicone emulsions consist of insoluble silicone droplets, which are uniformly dispersed in water.

multiple emulsions

multiple emulsions are more complex and consist of more than two phases, such. B. water-in-oil-in-water (W / O / W) or oil-in-water-in-oil (O / W / O), and can be formed with more than one emulsifice type.


microemulsions consist of micro-droplets of uniform size inserted into larger droplets of the preceding phases.

Advantages of emulsions

  • emulsions are a great way to combine two active benefits from two repulsive components
  • They are ideal as a moisturizer and depending on the type of emulsion, faster or slower into the skin or leave a rather silky, dry or rich finish
  • emulsions can serve as a basis for active ingredients

    emulsifiers and stabilizers - the secret of long-lasting emulsions

    Emulsifiers are defined as water-soluble polysaccharides and are obtained from plants, algae or microorganisms. Polysaccharides are a type of carbohydrate molecules consisting of long chains of single sugars.

    Your purpose in cosmetic formulations is to maintain or improve the stability, texture and natural appearance of preparations and ensure that these properties over one sufficiently long periods of time stay.

    The most important function of an emulsifier is to facilitate the dissolution and viscosity of the ingredients in an emulsion and thus to obtain their homogeneity and to avoid the formation of possible crystals, the affect your texture.

    In addition, stabilizers are able to change the mobility of the water, whereby the structural properties of an emulsion, such. As the rheology, the homogeneity of the appearance, functionality and physical stability can be adjusted during manufacture, distribution and end consumption.

    Another function of these additives is the formation and stabilization of the foam generated in a variety of cosmetic products.

    emulsion vs. emulsifiers

    While emulsions are a mixture of two different liquids, an emulsifier is a substance that supports the mixture of the emulsion.


    a co-emulsifier is a substance with low emulsifier, which can supplement another substance with higher force. I. A substance that alone can not stabilize emulsion, but in combination with another substance makes an emulsion stable.

    Microbial susceptibility of emulsions

    This microbial contamination of products must be urgently prevented, otherwise unpleasant side effects can occur after application. In particular, when water and oil are mixed to an emulsion, the susceptibility to a proliferation of the product is even higher than in pure water-based products. This is because the oils act as food as food for the microbial organisms created by the water.

    emulsions must therefore always be preserved and usually very effective preservatives should be used here.

    to maintain skin care without declarative preservatives, the lipid glory products of Craft & amp; Use Care.

    The oil-based balms and oil series of vegetable and controlled organic cultivation must contain no preservation systems because they contain no water.

    The water-based Lipid Glory products are formulated with multifunctional ingredients. These work in the product as well as on the skin of a concentration and donate the skin in addition to intensive moisture.

    Mix your individual emulsion

    the oil sera and pure vegetable oils of lipid glory, connect in seconds with the hydrating serum to a spontaneous emulsion.

    Emulsions can be practical in some nursing routines as they move faster and left another finish.

    with the lipid glory oils in combination with the hydrating serum, you can decide for yourself how easy or how rich, your fluid, your lotion or cream should be. Mix you, according to your individual needs, a fresh emulsion, completely without emulsifiers, additional preservatives, gelers or stabilizers.

    A small, any amount of the serum is mixed with a few drops of oil, in the hand inner surface with fast and circular fingers, to an emulsion and subsequently massaged.

    previously the skin can be prepared with the moisturizing and balancing balancing toner. Also the hydrating serum itself, can provide prior to application of the emulsion, for an extra moisture booster.
