The composition of oils will have an impact on their cosmetic properties and therefore on their uses.

At BeautyMix, we offer seven vegetable oils (sweet almond, hazelnut, sesame, argan, jojoba, hemp and oily carrot macerate) whose properties will be highlighted in this article. The comedogenic index will also be indicated in the table, with a result between 0 and 5: 0 being non-comedogenic and 5 being very comedogenic. A comedogenic oil will tend to clog the pores of the skin and therefore promote the appearance of pimples or blackheads.

This article will help you better understand which oil is right for you.

Oils are fatty substances composed of saturated or unsaturated fatty acids (with omega 3,6,9). Vegetable oil is therefore, by definition, immiscible in water or in alcohol, that is to say that it will not be able to dissolve in it. Depending on the temperature at which the oil will be stored, it may end up in its oil or butter state. The latter corresponds to a solid state.

An oil can be obtained by different processes which will have an impact on their final quality.

• The first technique is cold pressing: after sorting, the fruits and seeds will be cold pressed, that is to say at room temperature, in order to obtain a vegetable oil of excellent quality since the oil which contains it. The result will be as pure as possible and will contain all of these essential nutrients.

• The second technique is the mechanical press: the fruits will be crushed and heated a little. The resulting oil will be pure and will preserve all its dietary qualities. This is the most common method.

For oleaginous fruits, a centrifugation will be necessary in order to separate the oil from the pulp.

• Finally, the last process encountered is the solvent extraction which is certainly profitable but which gives an oil of poor quality.

Besides oils, there are oily macerates on the cosmetic market: they are obtained by maceration of a plant in vegetable oil. Example of oily carrot macerate.
