Definitions
- the subject of the present invention relates to the use polymeric aminodicarboxylic acids and their sodium salts and precursors in bleaching detergents, bleaching aids and detergents Bleaching liquors for textiles, such as those used in the household and in commerce become.
- the bleaching detergents commonly used today contain essential ones Components builder substances, surfactants and bleach. While the surfactants generally have the task of wetting the textiles to be washed and to remove and disperse greasy soiling the main tasks of the builder in it, the negative effects of Water hardness, which can be seen as incrustations on the tissue, as deposits on the heating elements of the washing machine and in the impairment of the general Express washing performance, prevent. While earlier than builder substances soluble silicates, borates and especially polymeric phosphates have recently been used primarily water-insoluble Zeolites and polymeric polycarboxylic acids or their salts as builder substances used in detergents.
- the common one is particularly common Use of zeolites with co-builders, for example polymeric polycarboxylic acids, which improve the effectiveness of the zeolites.
- Younger Time has been suggested as builder substances or co-builder substances polymeric aminodicarboxylic acids and their salts or also precursors of these polymers, which only in water to the polymeric aminodicarboxylic acids hydrolyze, use in textile detergents.
- builder substances polymeric aminodicarboxylic acids and their salts or also precursors of these polymers, which only in water to the polymeric aminodicarboxylic acids hydrolyze, use in textile detergents.
- the main focus of these substances is at the dispersing effect on pigments (primary washing action) and in the prevention of deposits (secondary washing effect).
- Oxygen bleaches are predominantly used as bleaches in laundry detergents used, primarily inorganic peroxo compounds, like sodium perborate or sodium percarbonate, but are for this purpose also organic peroxo compounds, for example peroxocarboxylic acids been proposed.
- the inorganic peroxo compounds in water Release hydrogen peroxide are often used with activators the effectiveness of hydrogen peroxide at low temperatures increase.
- bleaching detergents and bleaching aids additionally stabilizers for the peroxo compounds. It is primarily about Heavy metal complexing agents such as ethylenediaminetetraacetic acid, ethylenediaminetetramethylenephosphonic acid and other polyphosphonic acids or the salts of these acids.
- Heavy metal complexing agents such as ethylenediaminetetraacetic acid, ethylenediaminetetramethylenephosphonic acid and other polyphosphonic acids or the salts of these acids.
- the use of these complexing agents often requires Compromise on other properties of the detergent, so that for these complexing agents for exchange substances that do
- polyamino acids or their derivatives are used as builders or co-builder used in detergent formulations.
- polyaspartic acid and polyglutamic acid are preferred here polyaspartic acid and polyglutamic acid.
- Such polyamino acids show excellent properties as calcium complexing agent.
- amino acids such as L-aspartic acid and L-glutamic acid, as complexing agents usable for transition metals such as iron, cobalt and nickel.
- WO 96/34908 describes a process for the preparation of polymers with recurring Succinyl units, especially polysuccinimide and polyaspartic acid, described.
- An optionally substituted 1,4-butanedicarboxylic acid, Butenedicarboxylic acid or a derivative thereof with a triammonium salt combined with a polyvalent acid and with heating polymerized.
- Heavy metals can also be used as stabilizers for bleaches in these polymers how hydrogen peroxide serve in bleaching processes.
- This patent application represents a document within the meaning of Article 54 (3) and (4) EPC.
- One of the objects of the present invention was to improve to find the stabilization of the bleach in the textile washing process.
- polymeric aminodicarboxylic acids, their salts or their hydrolysable to polymeric aminodicarboxylic acid Precursors for the stabilization of peroxo compounds in bleaching Textile detergents, bleaches or bleach or wash liquors for textile treatment be used.
