"Laundry detergents for textiles"

The invention relates to a powdery or granular detergent with a textile softening effect for the same time Washing and caring for delicate items in the washing machine or by hand.

There has long been a need for a powdery one or granular mild detergents containing textile softeners, which gives the textiles the desired softening and antistatic properties during the washing process. Because of the known incompatibility of the usual textile softeners of the quaternary ammonium or Imidazolinium compounds with anionic surfactants was the use of anionic surfactants in such preparations locked out. It therefore made sense to use combinations of nonionic surfactants and quaternary ammonium compounds to use. So from GB-PS 8 ^ 0 864 are liquid detergents known the nonionic surfactants and quaternary ammonium compounds, which have a long-chain alkyl radical and have three short-chain alkyl radicals are known. According to the information in the journal Seifen-Öle-Fette-Wachse (1963), 4_, p. 78, the washing effect is more similar Combinations are particularly good when the ratio of the nonionic surfactant to the quaternary ammonium compound im Quantity ratio 4: 1 to 1: 1 is.

Powder detergents for machine washing based on non-ionic addition products of ethylene oxide of certain alkylphenols, fatty alcohols, mercaptans, fatty acid monoethanolamides or fatty amines as nonionic Surfactant components which contain cationic ammonium compounds for foam suppression are described in DE-AS 12 20 described.

However, these proposed solutions are unsatisfactory because these detergents are not in balance Washing power, soft mowing performance and foaming behavior can be reached in the washing machine and when washing by hand the technology does not take any stimulus, like a powdery one Detergent would have to be composed with an optimal combination of the desired properties. Of the Rather, the person skilled in the art had to assume that a detergent surfactant was the fabric softener present in the wash liquor would detach or keep away from the textile fibers together with the dirt and therefore the desired textile-making Effect could not occur. Conversely, a good softening effect would be insufficient with one to achieve cleaning surfactant.

The invention was therefore based on the object of providing a powdery or granular detergent for mild detergents, the optimum in washing power, textile softening properties and also in foaming behavior and which can be used both in the washing machine and for washing by hand.
