Definitions

• the invention relates to detergent mixtures of nonionic surfactants such as alkyl glycosides and anionic surfactants such as hydroxysulfonates, which are used as a component of reduced phosphate detergents or cleaning agents.
• detergents with reduced phosphate refer to those detergents which contain at most 30% by weight of alkali metal tripolyphosphates, but which can also be phosphate-free.
• EP 0 075 074A2 describes a detergent mixture of alkyl glycosides and anionic surfactants.
• EP 0 070 995A2 describes a detergent mixture of alkyl glycosides and nonionic surfactants.
• EP 0 105 556A1 describes a liquid detergent mixture which does not select anionic surfactants, alkyl glycosides contains ionic surfactants and optionally other additives.
• Detergents are currently mainly made from petrochemical raw materials.
• ABS alkylbenzenesulfonates
• ABS has good wetting and foaming power, but is only partially compatible with the skin, which can lead to allergies. Furthermore, ABS is only partially biodegradable.
• the present invention has for its object to provide a detergent mixture of a nonionic surfactant, such as an alkyl glycoside, and an anionic surfactant, such as a hydroxysulfonate, which is composed entirely of native, ie renewable, fat-chemical raw materials.
• This detergent mixture is intended to replace detergents such as ABS, which are made exclusively from petrochemical, i.e. non-renewable raw materials, in phosphate-reduced detergents and cleaning agents.
• the detergent mixtures according to the invention show a significantly better biodegradability compared to ABS in the closed bottle test and also a significantly better one Skin tolerance in the epidermal swelling test, as can be shown in the examples.
• phosphate-reduced detergents which contain the detergent mixture according to the invention have better washability than commercially available phosphate-reduced detergents based on ABS.
• the detergent mixtures according to the invention can be mixed in any ratio to one another, preferably the mixing ratio of alkyl glycoside to hydroxysulfonate is 10 to 90% to 90 to 10%.
• the products according to the invention remain liquid up to a content of 75% washing active substance (WAS), whereas products based on ABS already form precipitates at a content of 60% WAS and can no longer be pumped.
• WAS washing active substance
• Alkyl glycosides suitable for the purposes of this invention are described, for example, in US Pat. Nos. 3,547,828 and 3,839,318.
• Typical alkyl glycosides are those in which alkyl is octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl and mixtures thereof.
• Particularly suitable alkyl glycosides contain a coconut fatty alkyl residue, ie dodecyl and tetradecyl residues.
• the sugar component comes from the usual aldoses or ketoses, such as glucose, fructose, mannose, galactose, talose, gulose, allose, old rose, idose, arabinose, xylose, lyxose and ribose.
• aldoses or ketoses such as glucose, fructose, mannose, galactose, talose, gulose, allose, old rose, idose, arabinose, xylose, lyxose and ribose.
• the particularly preferred alkyl glycosides are the alkyl glucosides because of the good reactivity and easy accessibility of the glucose.
• the index number x is any number between 1 and 10, which indicates the degree of oligomerization, ie the distribution of monoglycosides and oligoglycosides.
• the value x for a specific alkyl glycoside process product is an analytically determined arithmetic parameter, usually one is a fractional number.
• the alkyl glycosides are represented by the formula RO (G) x , the percentage of fatty alcohol is neglected. In principle, this fatty alcohol portion can largely be controlled by gentle distillative treatment of the alkyl glycoside, ie the excess fatty alcohol resulting from the reaction can be removed from the product except for residual values which are less than 1% total.
• alkyl glycosides with essentially C12-C22-alkyl or alkenyl radicals belong to the type of nonionic surfactants.
• the hydrophobic part comes from renewable raw materials if it is derived from fatty alcohols and the hydrophilic part is made up of ethylene oxide units and thus from a petrochemical raw material, the alkyl glycosides as fatty alkyl glycosides can be made entirely from renewable ones Raw materials, namely fat on the one hand and sugars or starches on the other hand, are produced.
• Alkyl glycosides whose alkyl radical is derived from synthetic primary alcohols, in particular the so-called oxo alcohols, i.e. those primary alkanols, which have a certain percentage, mostly 20 to 40%, of branched isomers, mostly with a 2-methyl residue.
• oxo alcohols i.e. those primary alkanols, which have a certain percentage, mostly 20 to 40%, of branched isomers, mostly with a 2-methyl residue.
• surfactants are less preferred if the focus is on the intended use of surfactants with a natural raw material base, including the hydrophobic part.
• the group R2-CO can be a formyl, acetyl, propionyl or butyryl group; the acetyl group is preferred.
• the group R 1 is preferably an oleyl group or a fatty alkyl radical consisting predominantly of oleyl groups.
• Preferred values for the sum (y + z + p) in the compounds (II) and (III) are consequently 12 to 18, preferably 12 to 14.
• auxiliaries or additives in the sense of this invention are conventional constituents such as Builder substances, bleaching agents, foam stabilizers, complexing agents, optical brighteners, thickeners, dirt suspending agents, graying inhibitors, dyes, perfume oils, enzymes, bactericides, fungicides etc.
• surfactants can also be added to the mixture, provided that they do not interfere with the synergistic effect of the detergent mixture according to the invention.
• HOS C18 diolsulfonate Na salt based on Ocenol 90/95 (oleyl alcohol, technical)
• HOES5 C18 diol ether sulfonate Na salt based on Ocenol 90/95 with an average of 5 mol EO ethoxylated
• Zeolite NaA product that is used as an undried stabilized suspension that is still moist from manufacture. Enriched in the recipes as an anhydrous substance.
• the substances used had the chemical composition defined in Application Example 1.

• the degradability of surfactants can be assessed based on the biochemical oxygen demand (BOD) in microbial oxidation.
• BOD biochemical oxygen demand
• test was carried out over a period of 30 days in a closed system at a test concentration of 2 mg AS / I (for the test method see "Fette Seifen Anstrm.” 65 (1963) 37).
• a pig epidermis is placed in an aqueous solution of the surfactant to be tested and the swelling compared to pure water.
• the swelling factors for anionic surfactants and systems containing anionic surfactants found using this method correlate very well with measurements of skin tolerance in vivo (cf. J. Soc. Cosmet. Chem. Jap. 20 (1986) 17).
