Background information on use in cosmetics

Citric acid has a mild astringent and bleaching effect. It is also used as acid component for the pH value adjustment of cosmetics, eg in skincare lotions or creams. Fruit acids (INCI: eg CITRIC ACID or OXALIC ACID) become increasingly popular in cosmetic products and application. They make skin flakes and rough areas disappear, the skin becomes smoother and fine lines and wrinkles are reduced. In higher concentrations fruit acids dissolve the bonds of the increasingly accumulated dead skin cells of the stratus corneum and hence support their shedding. The natural new cell formation is indirectly promoted and supported and the elasticity of the skin is improved. In the event of oily skin fruit acids prevent the formation of spots and skin impurities. In this way the skin texture is altogether refined, the skin appears clearer and fresher. Fruit acids are added in low concentrations to some creams. They are for instance obtained from lemons, grapes or apples or synthetically produced. The use of fruit acids should be precisely adapted to the skin texture. The sensitive skin can, for instance, have an irritant reaction and not every skin tolerates an excessively frequent application of highly concentrated products. This is why the products available on the market today are particularly carefully selected in terms of concentration of the active ingredients and / or the adjustment of the pH value. After the application of higher concentrated fruit acid products, sun protection is important. A corresponding reference is to be found on the products. Fragrances or mixtures of fragrances are often referred to in the cosmetics area as "perfuming agents" or "perfume oils" or "parfum oils". On the cosmetic products they are declared with the INCI name "PARFUM". These are undiluted individual substances or their mixtures which originate from natural raw materials or can be produced (semi-) synthetically. They are starting materials for the production of perfume, eau de parfum, eau de toilette, eau de cologne and other perfumed cosmetic products. The average content of fragrances amounts in perfume to 15-30 %, in eau de parfum to 10-14 %, in eau de toilette to 6-9 %, in eau de cologne to 3-5 % as well as in skin creams, shampoos, hair and deodorant sprays to approximately 0.2-1 % and approximately 1-3 in deodorant sticks. The perfume oils include essential oils, resinoids and absolutes. The sources are, amongst others, flowers, leaves and stems, fruits and fruit peels or roots of plants; woods, grasses or herbs, needles, resins and balsams. Moreover, only compounds isolated from natural products such as aldehydes, ketones, esters, alcohols etc. are used (geraniol, citronellal, citral, eugenol, menthol) as well as semi-synthetic (citronellol, geranyl acetate, jonone) and synthetic scents (eg phenylethyl alcohol and linalool) are used. Scents of animal origin such as musk and ambra are only rarely used.
