DD271219A3 - HAUNTING AGENT BASED ON CATIONACTIVE DYES - Google Patents

Abstract

The invention relates to hair toning agents based on cationic dyes, which serve to the Toenen of human hair and can be offered as liquids, emulsions or gels. By using from 0.5 to 12 parts by weight of a highly ethoxylated fatty alcohol and 0.5 to 12 parts by weight of a Fettsäuredi and / or -polydiethanolamides, each calculated on a part by weight of the cationic Ausrest used, it is possible to obtain hair colorants with excellent performance properties, without there is an impairment of the dyeing effect.

Description

cationic polymers. The hair tinting agents produced in this way have excellent performance properties, which, in a global comparison, have not been met by any of the comparison products in the totality of the tinting and care properties. The hair tinting agents according to the invention can be applied without problems and lead to instantly recognizable care effects for the consumer. The hair is excellent in wet combability, does not load on drying, which prevents splitting when combing, gets a firmer feel (improved) and shows a silky natural shine after drying. The use of other care products, as recommended by other hair tinting agents, is therefore not required. The desired staining results are obtained after an exposure time of 5 minutes, although only low dye concentrations are used. This not only brings economic benefits, but also makes the product in dermatological safer.

However, it was completely surprising and unforeseeable that the competing reaction between the cation-active dyes and the water-soluble cationic surfactants or the cationic polymers was practically prevented by the addition of the highly ethoxylated fatty alcohol and fatty acid edi and / or polyethanolamides in the proportions indicated and the dyeing result Color intensity and leveling properties were as if these cationic suppliers were not included in the hair tinting agent.

Suitable highly oxyethylated fatty alcohols have been found to be saturated or unsaturated alcohols having 16 to 20 carbon atoms and a degree of ethoxylation of 50 to 100 mol of EO per 1 mole of fatty alcohol. Suitable fatty acid di- and polydiethanolamides may be those of saturated or unsaturated fatty acids having 12 to 18 carbon atoms.

Oxethylated fatty alcohols are commonly used in cosmetics adjuvants, which are used depending on the degree of EO as Überfettungsmittel and emulsifiers. With the EO degree, you increase solubility in water, and the interface-active properties decrease after reaching an optimum. This optimum is at EO grades between 6 and 12 (K. Lindner: Surfactants - Textile Auxiliaries - Washing Raw Materials, Vol. I, p. 881, Wissenschaftliche Verlagsgesellschaft mbH Stuttgart, 1964).

For special tasks, tools with 40MoI EO t are also known. From 50 MoI EO, the properties of the EO chain become so dominant that the surface-active properties virtually no longer change. (Moore and Bell, Am. Par'umer Cosm. 77 1962, 10 pp. 81 to 84). These compounds are notable for the strong intermolecular and intramolecular forces, which allow a variety of attachments and complex formation with other substances.

The Fetisäurealkylolamide mentioned are preferably as Rückfettungsmittel and foam stabilizers contained in Shampoepnparaten. In hair tinting lilies they are used, if at all, only in this sense.

Claims (3)

1. hair tinting agent based on cationic dyes in liquid, emulsion or gelatinous base with an effective content of water-soluble cationic surfactants and / or cationic polymers, characterized in that, calculated on a part by mass of these water-soluble cationic equipment contained in the hair tinting agent, 0.5 to 12 parts by weight of a highly ethoxylated fatty alcohol and 0.5 to 12 parts by mass of a fatty acid di- and / or polydiethanolamide. 2. hair tinting agent according to item 1, characterized in that the highly ethoxylated fatty alcohols are those of saturated or unsaturated alcohols having 16 to 20 carbon atoms and 50 to 100 moles of EO per mole of alcohol. 3. hair tinting agent according to item 1, gekonnzeichnet in that the fatty acid di- and / or polydiethanolamide are those of saturated or unsaturated fatty acids having 12 to 1b carbon atoms. Field of application of the invention The invention relates to hair tinting agent based cation-active dyes for ^r tones of human hair. Characteristic of the known solutions Hair toners have essentially the task to refresh the natural hair colors or to nuance the hair fashionable. They are cosmetic preparations, which may preferably be in the form of viscous solutions, shampoos, emulsions or gels. As dyes have been used almost exclusively substantive, direct zie in compounds that belong to a variety of classes. In this case, dyes which contain no ionic group in their molecule, as they are mentioned in DE-PS 3534885 and 3442366, unsuitable because they are insufficiently soluble, require high dye concentrations up to 4 and 5% and 20 b-w. For 30 minutes on the Ha? 'Must act to give the desired color. Another disadvantage of these dyes is their insufficient storage stability in the tinting agents, which means that they do not color out in a nuanced way after just a few months. These deficiencies do not show dyes that contain a quaternary ammonium group and as a cationic compound have a particularly high substantivity to the hair keratin. Such dyes are e.g. in CH-PS 391190 Deschrieben or belong to the corresponding azo and Chinoiminverbindungen, which are known under the trade name ^ Arianor. In addition to the high dyeing requirements that must be met by cationic dye-based hair tints, they are also expected to impart immediately recognizable conditioning properties to the hair, such as ease of wet combing, antistatic finish, gloss and feel enhancement. Such use properties are realized in modern hair care, curative and rinse preparations almost exclusively by the use of water-soluble cationic surfactants or suitable cation-active polymers in concentrations of 0.5 to more than 3.8%. These compounds, which are also referred to as suppliers, have a very high substantivity to the hair and immediately block all sorption centers there. Used together with the cation-active dyes, they therefore affect the dyeing result, since the dyes are due to their molecular structure very little noun. So far, this competition reaction could only be avoided by adding no or only insufficient amounts of a water-soluble cationic surfactant or a suitable cationic polymer to the hair tinting agent based on cation-active dyes and thus making sacrifices to the caring use properties or completely dispensing with siu. The interaction and difficulty could not be eliminated even with the cationic gel described in DD-PS 217987. The gelling agent is only slightly noun, does not affect the dyeing effect and can be completely unwind, but can also convey so no nourishing properties. Object of the invention It is the object of the invention to develop hair toners based on cationic dyes, which give a good dyeing result and at the same time gives the hair clearly recognizable nourishing properties. Explanation of the essence of the invention The object was to develop hair toning agents based on cationic dyes with an effective content of water-soluble cationic surfactants and / or cationic polymers, so that the hair clearly recognizable, nourishing properties are conveyed, without causing an impairment dos the staining results. Erfindu igsgemäß the object has been achieved in the way that the hair colorants based on kationaktiviver Fa substances from 0.5 to 12 parts by weight of a highly ethoxylated fatty alcohol and 0.5 to 12 parts by mass of a F tartäuredi- and / or -polydiethanolamides, each calculated on a mass fraction the water-soluble cationic surfactants contained in the hair tinting agent and / or
