After the washing, dyeing or permanent waving process, it is common practice to give the hair a finishing treatment subdue with a hair setting agent. The hair is strengthened, it can be do your hair better, static charges and the influence of moist air are reduced.

Plant mucilages, modified celluloses, alginates, polyvinylpyrrolidones, Polyvinyl alcohols, polyacrylates, -methacrylates and other film-forming substances used the in combination with plasticizing substances, such as B. polyglycols, alkyl phthalates and others., An elastic Form film. An essential requirement that must be met by the plasticizers is that Property of being non-volatile or at least not very volatile, since otherwise it will take a very short time Time to embrittlement of the film and thus to abrasion and the associated undesirable Properties can come. The concentration and composition of resin, plasticizer and the other modified components depend on the strength of the required consolidation, the gloss and the degree of abrasion resistance.

The combination of setting substances and dyes for the setting tint of the hair has is also well established in practice.

While the properties of the various combinations of hair setting agents change the instant Requirements that are placed on them, essentially meet, result from the for Time solvents used, drying times that are common to both the patient and the hairdresser represent a decisive loss of time.

So far it has been the case that the toweled hair after the previous treatment with a different Amounts of alcohol-containing or alcohol-free hair setting agents massaged, wrapped and were dried. The hair setting re-supplies the hair with considerable amounts of water, additionally drying with a hood dryer or hair dryer for a period of 20 to 30 minutes, possibly even longer, stretch.

The drying time is essentially dependent on the total amount of moisture, namely after remaining in the hair after the toweling and the amount of moisture supplied by a hair setting agent.

B i 1 d 1 illustrates the drying time of human hair when different amounts of water are added. The experiments were carried out as follows: The hair of a model head was washed, rubbed and the head was weighed. Then the hair was mixed with certain amounts of water, for a quick-drying hair-setting agent

Rolls rolled up and ^{dried at 50 °} C. under a drying shark. The weight loss in water was determined by weighing after certain times. The curve shows that the drying time is a pure function of the amount of water to be evaporated.

If the model head is moistened with 43 g of water under the test conditions before being placed in it is, results in a drying time of 60 minutes, while with a weight fraction of about 22 g Water a drying time of 20 minutes results.

The hair already loses part of its water content while it is being inserted, so that it is under Under certain circumstances, if the water content is too low, difficulties in winding can be found.

You can get fast-drying hair setting agents if you use aqueous-alcoholic solutions instead uses pure alcohol or other rapidly evaporating organic solvents. Such means but have the disadvantage that they dry so quickly on the hair before the hairstyle is applied, that winding up the hair brings difficulties for the practitioner.

It has now been found that by adding the organic solvents used according to the invention the drying time during winding is slowed down without the hair under the hood need to dry noticeably longer.

The organic solvents used according to the invention thus only have the function of the hair to keep moist at normal temperature for a longer period of time and thus to insert the water wave facilitate. At an elevated temperature under the dryer hood, those used according to the invention evaporate organic solvents, while those from the resin, the plasticizer and the modified
