Definitions
- the invention relates to a process for the production of hair-fixing products in the form of a film, and to hair treatment compositions for setting hair in the form of a solid, water-soluble film, in particular based on pullulan and, if appropriate, additional hair-fixing polymers.
- hair treatment agents are generally used in the form of gels, foams, sprays or lotions based on liquid solvents.
- a disadvantage of such solvent-based products is that, owing to the high solvent and / or propellant content, they are voluminous and heavy and are therefore unsuitable for taking along on the go. The problem is usually solved by packaging the products in very small containers. Such products have the disadvantage that they are only sufficient for very few applications. In addition, it is not possible to portion them into solid, discrete pieces that are sufficient for an application during manufacture. Also a spatial one

- Rollable doughs are prepared from compositions A, B and C using water as the solvent. By rolling the dough, foils are made and the foils are then dried.
- the films were assessed on the basis of the following criteria: (a) very good solubility behavior when rubbed with hands with a little water: ++; good: +; sufficient: 0; bad: - (b) foaming behavior when worked into the hair no foaming: +; Foaming: - (c) stickiness behavior good stickiness: +; bad stickiness: - (d) flocculation behavior when worked into the hair: no flocculation, no formation of visible residues: + flocculation, visible residues: - (e) setting behavior: good hair fixation: +, - weak hair fixation: 0; no hair fixation: -
- Hair styling films made from preparation A are very elastic and can be processed easily, ie they can be dissolved with a little water in the hand and worked into the hair.
- Films made from preparation B are brittle and brittle and are less easy to process.
- Films with a size of 4 x 4 mm are produced and each treated with 0.03 g of aftertreatment agent. All foils are not sticky and can be separated easily. The corresponding films without post-treatment, on the other hand, stick to one another after storage for some time and can no longer be easily separated from one another.
