Definitions
- the invention relates to the use of phosphonic acid-modified polyacrylates as sequestering agents for the production of aqueous bleaching agents.
- liquid bleaching agents preferably based on hypochlorite
- hypochlorite solutions can dissolve iron and manganese ions from the walls of the washing machine, which subsequently catalyze photochemical reactions and lead to yellowing of the laundry. While the market tries to prevent this redeposition by using polyarylates [DE 19730650 A1 (Henkel)], in practice this measure does not always prove to be satisfactory.
- the complex object of the invention was to prevent the yellowing of the laundry by depositing traces of metal on the fabric and to provide sequestering agents which allow the production of aqueous bleaching agents, in particular chlorine bleaching solutions, with high stain removal properties, chlorine-stable, textile are gentle and as kind to the skin as possible and have a sufficiently high viscosity.
- the invention relates to the use of phosphonic acid-modified polyacrylates as sequestering agents for the production of aqueous bleaching agents.
- Polymers based on esters of acrylic acid with a characteristic chain building block of the formula (I) are referred to as polyacrylates,
- R 1 represents hydrogen or a linear or branched hydrocarbon radical having 1 to 22, preferably 2 to 12 and in particular 3 to 8 carbon atoms.
- Typical examples are polymers of acrylic acid and their esters with methanol, ethanol, propanol, isopropyl alcohol, n-butanol, isobutanol, sec-butanol, tert-butanol, pentanol, capron alcohol, caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, Myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolyl alcohol, linolenyl alcohol, elaeostearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, technical grade alcohol and methylettenes
- Homopolymers or copolymers of acrylic acid and their methyl, tert-butyl or 2-ethylhexyl esters are preferably used.
- the resulting polyacrylates are modified with phosphonic acid, the point of attachment of the phosphonic acid group being on the carbon chain.
- the polymers obtained can have average molecular weights of the order of 300 to 50,000, preferably 1000 to 30,000 and in particular 5,000 to 10,000 daltons exhibit.
- the phosphonic acid-modified polyacrylates are used in combination with other already known polyelectrolytes. These support the sequestering effect of the polyacrylates according to the invention.
- R 2 and R 3 represent hydrogen, an alkali and / or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium and n represents numbers from 0 to 64.

- the dicarboxylic acids can be mono- or polyunsaturated and / or have an aromatic ring instead of the alkylene groups.
- Typical examples are maleic acid, fumaric acid, sorbic acid, phthalic acid and terephthalic acid. Neutralization takes place when the acids mentioned are introduced into the alkaline bleaching agents. However, they can also be used directly in the form of their salts, preferably as sodium salts. The use of adipic acid or sodium adipate as the polyelectrolyte is particularly preferred.
- (b) Low molecular weight polyvalent hydroxycarboxylic acids are suitable polyhydric hydroxycarboxylic acids. Typical examples of suitable polyhydric hydroxycarboxylic acids are malic acid, tartaric acid and in particular citric acid. These acids can also be used in the form of their alkali and / or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium salts.

Unsaturated dicarboxylic acids that can be used as monomers have already been mentioned under (a).
- maleic anhydride is preferably used because of its high reactivity and low price.
- the products that can be produced, for example, by hydrolysis of polymaleic anhydride have a high charge intensity.
