DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to the field of cleansing and/or care agents, especially for hair, a field which can no longer be imagined to be absent from modern life and which extends from the personal need for health, hygiene and aesthetics to the human-socioeconomic, service and professional cosmetic industry.
In modern life, in the private as well as in the commercial sector, it is very important now and will be even more important in the future that the substances which make up the aforementioned materials and which are, of course, defined more or less by the requirement of compatibility with the human body, are compatible with the environment, especially with respect to their wrapping, packaging, presentation, repackaging as well as their disposal.
Since quite a long time, the hair cleansing and care product industry is dominated without a serious challenging differentiated product by various shampoos for various specific purposes, where these dominating shampoos are always supplied in a highly viscous, liquid-creamy or creamy form with often rather similar functionality.
Every conceivable package variety which packaging technology can supply, is available in a form which is relatively easy to handle, but environmentally not very friendly, starting with single-use packages for a single shampoo or hair care event, where such shampoos and hair care products are packaged in envelopes pads, bags, blister packs and sacks, to a container or bottle with a special closure which is a very effective advertising tool, but very costly to implement; in addition, there is a tendency to package everything, if at all possible, in form of more and more involved, self-contained hair care sets or series. Aside from glass containers, this field is dominated by all different types of plastic materials; the problems associated with the disposal of the large quantities generated by their continuous use, however, need not be discussed at this place.
Because of the magnitude of the aforementioned problems, which at first do not appear serious, but should not be underestimated, it is the object of the invention to reduce and optimize in the hair care industry the extent and specifically the volume of packaging materials in an environmentally responsible fashion, without in any way impeding the ease of handling of the hair care products.
It has been recognized that in order to realize this object in the hair care sector, it would be very advantageous to provide shampoos and hair care products in a compact, solid form, without the unpleasant side effects of handling powders. However, the dispersion and dissolution speed of their active ingredients during hair cleansing and hair care does not always match the expectations of the modern consumer for "instant" availability. Therefore, the general concept of something like a hair shampoo or hair treatment tablet had to be developed which must, however, also offer a system which promotes a rapid dispersal of the ingredients comparable in speed to the dispersal of customary shampoos in wet hair.
2. Background of the Invention
The following comments apply to the present state of the technology for dispersing materials with the aid of gases:
A formed solid bath additive is described in AT-PS 253 123, which, however, does not make reference to a "hair wash" which is rather different from a full bath. This bath additive, which is not identical to a hair cleansing agent, is designed such that the gas is not forming at a time when the material has already come in contact with the bath water; rather, the generation of CO.sub.2 already takes place during the fabrication process of the formed solid bath additive and stops before the completion of the production process. The only function of the gas is that of a foaming agent and the gas is already completely embedded into the pores in the surfactant melt. The gas is not capable to advance "crumbling" or mechanical disintegration of the tablet and to disperse its surfactants through a spontaneous
