By incorporating mineral oil using known means, for example Aluminum stearate or paraffin wax or the like Means are easily subject to a separation of the liquid oil (syneresis), a brittleness of the gel structure, a shrinkage in their storage vessel and have poor ability to stray. Because of these characteristics and these remedies find little satisfactory and unsatisfactory Use only to a limited extent.

AuohdLe heavier oils in liquid form are difficult Spread thinly and evenly on the hair, while the thinner oils tend down on the hands and hair on the eye or the neck or along the collar Shoulders and other parts of clothing eu drip.

Means consisting of liquid oils are also not very satisfactory with regard to their cleaning and cleaning effect. The oil is not absorbed into the hair and causes as far as it gives the hair a hold, a disadvantageous one Bilge and slndruok sticking to the hair.

As already stated, the polyamide resin is a solid, but volatile condensation product of an aliphatic dicarboxylaic acid and a diamine (a mixture of compounds with more than 2 carboxyl or imino groups).

The use of other mineral oils in Tielon systems Leads to egg-like, voluminous selenium, Jedoeh can the other mineral oils are crystal clearer for their manufacture Systems by derogation of the medium fraction reuse.

The temperature is lowered below 100 ° C and ee under further Buhren de · mixture the Ycrsohicdenen Supplements introduced. Be is then hardened and turned into suitable Container filled.

A further improvement is obtained by using suitable mixtures of the solvents and resins Mineral oil, i.e. a solvent for the resin, which forms a solution that is miscible with the mineral oil. As a result, the proportion of mineral oil is increased with a corresponding reduction in costs, while the higher temperature table and the clarity of the gel is preserved:

The above emulsion is an example of an anionic one System. Those skilled in the art of making clay emulsions will readily see that similar Systems through the use of non-ion isolates and cationic emulsifiers or combinations of both can be produced.

In the formulas given above, the Poyamidhare leads together with the andesm ingredients to a better one Hair care and greater brilliance than with conventional formulas.

The hair care properties of the polyamides in the gel systems were used in "half-headed experiments" as follows established:

A drop of clear gel the size of a fingernail was weighed and liquefied by heating in the palm of the hand and applied to the hair on one half of the

• / 17 009809/1675 BAD

Applied to the head. An equivalent · weight of the same Jormel, but without polyamide, was based on the the other half of the same head applied. Both Halves were known identically and the halves with regard to Brlllans »Relnigungselgensehaften and hair fixers properties compared. The results show that the head half containing the polyanide carrier was superior to the other half. The above attempt is nooh more demonstrative when nan hair strands of identical Hair used in place of the halves of the head.

The preceding examples illustrate the invention, but do not restrict it.
