Description

APPLE WAX COMPOSITIONS

The present invention relates to the use of apple wax as an additive in a composition for treating a surface, the surface being selected from the group consisting of a wooden surface, a ceramic surface, a plastic surface, a leather surface, a metal surface and a surface of a medicament preparation. The invention further relates to a composition for the treatment of a wooden, ceramic, plastic, leather or metal surface and a composition for the treatment of the surface of a pharmaceutical preparation, said compositions containing apple wax. The invention also relates to apple wax-containing candles.

The use of care products for the surface treatment of in particular smooth surfaces, such as the surfaces of furniture, painted objects and automobile bodies, is well known. These care agents, which are also regularly referred to as polish, can in particular also contain camauba wax. Especially for the care of motor vehicle bodies, care products with a proportion of camauba wax are often used due to the advantageous care properties of carnauba wax, although care products of this type are comparatively expensive. Camauba wax is obtained from the leaves of the carnauba palm, which are covered on both sides with a powdery wax layer. This partly comes off after the leaves have dried, the rest is removed from the lengthways split leaves by brushing, tapping and scraping. The wax is then melted and the contaminants that settle are removed and sieved. The special features of this wax are its high hardness and its high melting point of over 80 ° C. It is also known to add gloss to surfaces. Because of these properties, camauba wax is particularly suitable as an additive in furniture or lacquer care. geproducts. Here it provides a special shine and, due to its hardness, protects the wood or varnish permanently and seals roughened surfaces.

The disadvantage of carnauba wax-containing polishes, however, is, among other things, that - in addition to the comparatively high price - it is often difficult to apply and the gloss that can be achieved with these polishes is usually in need of improvement. In addition, the yield of care products containing carnauba wax (i. E. The size of an area that can be treated with a given amount of the coating agent to achieve the desired gloss) is often in need of improvement.

Carnauba wax-containing candles are also known from the prior art. However, the disadvantage of such candles is that they often burn too quickly.

In general, it is an object of the present invention to at least partially overcome a disadvantage arising from the prior art. An object of the invention is, in particular, to provide a polishing agent which can be applied more easily and in comparison to the polishing agents known from the prior art, in particular in comparison to the polishing agents known from the prior art containing carnauba wax as an additive to polishes containing carnauba wax leads to a better gloss. The yield of these care products should also be improved compared to conventional care products containing carnauba wax in particular.

Another object of the present invention is to provide a candle which is characterized by improved burning behavior in comparison to the candles known from the prior art, in particular in comparison to the candles containing carnauba wax known from the prior art.
