Background information on use in cosmetics

Jojoba oil (INCI name: simmondsia chinensis seed oil) is obtained from the seeds of the jojoba shrub growing in the deserts and semi-deserts of North and Central America and is actually no oil. It is rather a wax which is liquid at ambient temperature. Liquid waxes are esters from unsaturated carboxylic acids and / or unsaturated alcohols. They are characterised by a very good spreading ability, ie they have the ability to spread very well and rapidly on the skin. They can be well distributed, they penetrate well and cause a pleasant feeling on the skin; moreover, they can also be used as solvents for lipophilic (lipo-soluble) substances. Jojoba oil is very similar to the skin’s own waxes and is, therefore, combining very well with the latter. It increases the elasticity of the skin and protects it against the loss of moisture. Moreover, jojoba oil contains Provitamin A and Vitamin E, which has an antioxidative effect. As a result of the large number of fatty acids, jojoba oil has a caring and smoothing effect. Because of the moisture binding properties it is highly appreciated, more particularly, for more mature and dry skin. Despite its many active ingredients, care products with jojoba oil are not oily but are rapidly absorbed. In haircare, jojoba oil ensures intensive care and an easier combability. Macadamia is a plant genus in the family of protea (proteaceae). It is mainly its fruit, the macadamia nut, of the two species macadamia integrifolia as well as macadamia tetraphylla, which is known and only occurs in Queensland, New South Wales and subtropical Eastern Australia. The plant parts of the macadamia used are, for instance, the fruits, the seeds and shells. Depending on the plant part used or the extraction process (pressing, alcoholic, oily and aqueous extracts), the different components of the plant are used for different purposes in cosmetics. Above all the oil of the macadamia nut is used in cosmetics, eg as a fatty base oil. Macadamia nut oil (INCI: MACADAMIA INTEGRIFOLIA SEED OIL) is obtained from the ripe nuts of the macadamia tree. After the harvest the oil which can be used perfectly well as edible oil or in cosmetics is obtained from the chestnut-like fruits with an oil content of up to 78 % by gentle pressing. The oil of the macadamia nut contains a high share of mono- and poly-unsaturated fatty acids such as palmitoleic acid, a component of the skin’s own lipids in the epidermis. Moreover, the oil contains valuable ingredients such as the vitamins A, B, E and minerals. The oil has a skin smoothing, softening and regenerating effect. In cosmetic products it is frequently used as an exclusive body oil. Hair packs with macadamia nut oil are used as care products for dry and brittle hair as well split ends.
