The invention relates to a method for improving skin friendliness, foam stability and the conditioning effect of detergents made from synthetic washing active substances compared to native ones and synthetic fibers or fiber structures.

By adding higher molecular weight amine compounds, namely secondary alkylolamine ethers Active washing base substances for the manufacture of synthetic cleaning and personal care products in bar form properties such as foaming power, abrasion, swamping, skin tolerance, are favorably influenced; according to German patent specification 1,026,906, even small amounts are sufficient Amounts. It has been shown that an increase in the addition of secondary alkylolamine ethers does not lead to better results, d. that is, even with the relatively low addition of about 4% is the optimum of the improvements that can be achieved with secondary alkylolamine ethers.

In the interests of the consumer, however, it is desirable to further perfect synthetic detergents in their properties.

It has now been found that the skin friendliness, the foam stability and also the emollient, d. H. conditioning effect of detergents compared to native and / or synthetic Fibers and structures fabricated from them can be improved considerably if one in the production of the Detergent homogeneous to the conventional organic synthetic and / or inorganic base materials Mixtures of higher molecular weight alkylolamine ethers and alkyleneoxylated alkylamines are added.

The higher molecular weight alkylolamine ethers can be used as secondary and tertiary compounds, accordingly the formulas

and χ is an integer between 1 and 8.

Instead of ethylene oxide, other alkylene oxides, in particular propylene oxide, can also be added. The alkylenoxylated alkylamines and the alkylolamine ethers can be wholly or partly in the form of their quaternary compound obtained by the action of dialkyl sulfates can be used.

Instead of the basic alkylolamine ethers and the alkyleneoxylated alkylamines, their Salts with polybasic organic acids such as citric acid, maleic acid and especially nitriloacetic acid (Chelate acid) or the like, come to use.

The feature of the invention resides in the incorporation of the claimed mixture. It is known that the Addition of cationic substances, e.g. B. from alkylamine ethers, to anionic, liquid surface-active Substances leads to flocculation, as a result of which such additives do not have an effect and the end products impair in properties and appearance. In contrast, leave the claimed mixtures can easily be used together with anionic synthetic detergents without - despite their basic-cationic character - flocculation occurs; the detergents made with it are characterized by good storage stability.

The homogeneous mixtures of higher molecular weight alkylolamine ethers and used according to the process alkyleneoxylated alkylamines can, for example, by melting the following components together getting produced:

1. 50 parts of a diethanolamine substituted with ethereal fatty acids with a higher molecular weight, z. B. Monolauryl diethanolamine,

50 parts of a palmitylamine which is substituted with three alkylene oxide radicals;

409 627/362

2. 50 parts of an ethereal sub with two lauryl residues

substituted triethanolamine,

40 parts of one substituted with five ethylene oxide radicals Oleylamine,

10 parts of a fatty alcohol substituted with 8 to 20 moles of ethylene oxide (AeO), e.g. B. commercially available Oleic alcohols with an iodine number of 50 to 55;

3. 30 parts of a triethanolamine ether substituted with two cetyl radicals like an ether,
70 parts of an oleamine substituted with 5 moles of AeO, which was quaternized by reaction with 1.1 moles of dimethyl sulfate and then purified by washing;

4. 20 parts of a triethanolamine ether substituted in ethereal fashion by two oleyl radicals,
80 parts of an ole amine substituted with 5 moles of AeO, which was quaternized by reaction with 1.1 moles of dimethyl sulfate and then purified by washing;

5. 50 parts of the citric acid salt by two

Cetyl residues of ether-like substituted triethanolamine ethers,

50 parts of an oleinamine substituted with 5 moles of AeO, which was quaternized by reaction with 1.1 mol of dimethyl sulfate and then purified by washing;

6. 70 parts of dicetyltriethanolamine ether,

30 parts of the maleic acid salt of palmitylamine substituted with 5 moles of ethylene oxide.

The number of examples can be expanded as required.

Together with the claimed mixtures, small amounts of ethylene oxide substituted Fatty substances, especially fatty alcohols with about 8 to 20 moles of ethylene oxide, as solubilizers can be used.

The resulting liquid, paste, powder or lump cleaning or personal care products are distinguished by remarkably improved properties with regard to skin-friendliness and foaming power and foam stability; compared to textiles made from native and / or synthetic fibers a significantly improved plasticizing, i.e. H. conditioning effect determined. Shampoos result in soft, easily manageable hair that is no longer prone to electrostatic charge.

Example A.

In a liquid fatty alcohol sulfate with organic bases, e.g. B. isopropanolamine, is neutralized and about 30% WaS, 3 parts by weight (= 10% of WaS) of the mixture 1 with heating solved; the viscosity of the fatty alcohol sulfate is increased somewhat by the addition, but it also remains as it is Cool down clear. The product is ideal as a shampoo; one achieves - with good cleaning of the hair and scalp - a soft hair that is easy to style.

Example B.

In a liquid synthetic base containing 30 to 45% WaS for a foaming bath preparation, consisting of a mixture of fatty alcohol and fatty alcohol ether sulfate, 2 to 8% (calculated on WaS) Mixture 3 dissolved with heating, then the usual fragrances and dyes added. A foam bath preparation is obtained which is characterized by good foam stability and skin tolerance excels; As in Example A, the addition causes an increase in viscosity.

Example C

In a base containing about 60 to 90% WaS for a pasty bath or hair shampoo,

ίο consisting of a mixture of known surface-active substances Substances, similar to Example B, are dissolved 4 to 8% mixture 4 with heating; subsequently become colors, fragrances and active ingredients added as usual. Such concentrates are good for storage and Warehousing; they can be used either with water or with aqueous alcoholic solutions, as desired be diluted.

Example D

In the production of a synthetic detergent in the form of bars, besides known high percentage active washing substances mixtures according to 1 to 6 in amounts of 1 to 12% (based on WaS) incorporated homogeneously during the usual mixing and piling process. Become useful the claimed mixtures were previously melted by heating. Both the familiarization in the basic materials as well as the subsequent stranding and embossing of the pieces do not produce any Difficulty. Syndet bars of soap are obtained which, in use, are different from a normal bar of soap do not differentiate, but have the advantages that they do not react alkaline, that they are both in the In cold as well as in hot, in soft as well as in hard water, foam quickly and that they do not Cause rim in sinks and bathtubs. When used as a shampoo, they give a voluminous, soft hair which, due to the reduced tendency towards electrical charging, is easy lets you do your hair and lies well. As a bath soap, the washing bars impair the foam volume of at the same time used bubble bath preparations.

Example E.

A ready-to-use powder detergent, consisting of conventional synthetic detergent active substances (Sulfates, sulfonates, nonionic substances), complexing phosphates, silicates, Perborates, optical brighteners, etc., are about 1 to 5% of a mixture after 3 after the previous one Applied melting, ζ. B. inflated. With this washing powder a full, soft wash is obtained, as they can with a detergent of the same composition without the additive according to the invention can be achieved.

Example F

On a ready-to-use powdery mild detergent, which is sprayed in a known manner from or atomize surface-active substances and the usual builder substances such as sulfates and phosphates etc., are applied similarly to Example E about 3% mixture 5, previously fused or blown up. A mild detergent is obtained which is excellent for washing textiles which tend to become electrostatically charged. They show very well after washing

cleaned delicates no longer have a tendency to become electrostatically charged.

Example G

On mixtures of complexing phosphates, such as sodium tripolyphosphate, tetrasodium pyrophosphate or the like, on their own or in admixture with chelates of the alkali metal salt type of nitriloacetic acid or Tetraäthylenediaminoacetic acid od. Ä., 10 to 15 parts by weight of a mixture 3 or 6 after previous Heating applied, preferably sprayed on. A dry powdery basic mixture is obtained, which can be added to finished detergents in order to have these additional advantageous properties to rent. The basic mixtures can be kept in stock without any problems and can optionally can be added to the various detergents.

Example H

Synthetic flakes based on high percentage washing active substances in connection with phosphates, Perborates, etc., which are used in particular for washing textiles that are easily electrostatically charged, about 3% of a mixture 1 and / or 3 is poured in. Synthetic flakes are obtained that have an excellent as Have cleaning and foaming power and at the same time give the washed textiles a fullness give a soft grip; such textiles no longer tend to become electrically charged as easily as this is the case without using the claimed additive.
