DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to cosmetic compositions having skin calming and skin regenerating effect and a process for the preparation thereof.
BACKGROUND OF THE INVENTION
In the cosmetic industry cosmetic compositions containing the extracts of natural substances (plant or animal organs) as active ingredient have again become popular.
The so called phytocosmetic compositions which belong to this class contain the extracts of various plants, mainly of medicinal plants (among others camomile, burdock, cucumber, lemon etc.) or that of the waste or the valuable parts of the cultivated plants (HU-PS Nos. 178,786 and 179,886, DOS No. 2,641,233).
One characteristic feature of tired skin is a decrease of the easily utilizable sugar content of the cells. According to the GB-PS No. 1,286,156 the loss of the natural sugar content of the skin can be recovered by cosmetic compositions which contain mainly glucose and fructose and optionally ribose, dezoxyribose and glucosamine. The composition can be used as a powder or in admixture with the usual cosmetic vehicles.
The aim of the present invention is to prepare cosmetic compositions suitable for calming and regenerating tired, dry skin.
BRIEF DESCRIPTION OF THE INVENTION
During our experiments it has been surprisingly found that the extract of Jerusalem artichoke (Helianthus tuberosus L.) is suitable for the above purpose.
DETAILED DESCRIPTION OF THE INVENTION
The invention relates to cosmetic compositions having skin calming and regenerating effect comprising the extract of the aerial shoot and/or tuber of Jerusalem artichoke as active ingredient together with the usual vehicles and/or diluents and optionally other known additives.
Jerusalem artichoke is a tuberous plant belonging to the compositae, the tuber of which in contrast to the potato does not contain starch but it contains inulin as reserve nutriment. The inulin content of the tuber is about 14 to 16 %. Due to the inulin content of the tubers Jerusalem artichoke is generally used in the food and distilling industry because in the course of the acidic hydrolysis of inulin mainly D-fructose and about 6 % D-glucose are formed. The hydrolysis of inulin takes place faster and more easily than that of potato starch. The hydrolysis takes place also in diluted acetic acid but it is enough to boil the tubers in water for some hours.
The other characteristic feature of Jerusalem artichoke is that in the course of its growth season fungus infections are only rarely observable and the rare infections do not spread (I. Izso, The Jerusalem artichoke, Akademiai Kiado, Budapest, 1955). Based on this observation we have examined the extracts of the aerial shoots and it has been found that the extracts show a considerable fungicidal activity against several fungi.
According to the invention extracts are prepared from the aerial shoot and/or tuber of Jerusalem artichoke and the extracts were used separately or in combination as active ingredients of cosmetic compositions. During our experiments it has been found that the extract of the aerial shoot and the syrup prepared from the tuber as well as their combination are remarkably suitable for calming and regenerating tired skin and for treating certain inflammatory conditions.
The favorable effects of the compositions of the invention were examined in the following way.
The face tonic (Example 7) was examined on 50 women aged from 20 to 63 years. It was applied after thorough cleaning twice daily, in the morning and in the evening. The treatment was continued for two weeks. The following types of the face skin were examined: 40 slightly dry, 10 sensitive dry skins. The tonic has been absorbed well during each treatment, the skin became smooth, velvety. During the treatment no allergic reaction, irritative dermatitis or hypersensitivity were observed.
The body lotion (Example 5) was tested on 22 women aged from 19 to 72 years. The lotion was applied after thorough washing twice daily, in the morning and in the evening. The treatment was continued fo
