Definitions

  • the present invention relates to granular detergent compositions and a process for producing the granular detergents. More particularly, the present invention relates to granular detergent compositions having an improved solubility.
  • GB-A-2 158 087 discloses granular non-caking detergent compositions comprising amine or quaternary ammonium fabric softeners.
  • the present invention is directed to a granular detergent composition
  • a granular detergent composition comprising from 0.01% to 50% by weight of an anionic sulphonate surfactant, from 0.01% to 45% by weight of a hydrotrope and from 0.5% to 5% by weight of a cationic surfactant.
  • the granular detergent composition is substantially free from an anionic sulphate surfactants, and is coated with a water soluble coating material that is a mixture of an anionic sulphonate surfactant and a hydrotrope.
  • the granular detergent according to the present invention can provide an improved solubility even in cold water with little of no reduction in cleaning performance.
  • An anionic sulphonate surfactant is an essential ingredient for the granular detergent of the present invention.
  • a preferable anionic sulphonate surfactant includes the salts (or optionally the acids) of C5-C20 linear or branched alkyl benzene sulphonates, alkyl ester sulphonates, C6-22 primary or secondary alkane sulphonates, C6-C24 olefin sulphonates, sulphonated polycarboxylic acids, alkyl glycerol sulphonates, preferably derived from alcohols derived from tallow or coconut oil, fatty acid glycerol sulphonates, fatty oleyl glycerol sulphonates, and mixtures thereof.
  • the cation of the anionic sulphonate surfactant may be any appropriate cations such as sodium, potassium, hydrogen, ammonium or alcohol amine, preferably, sodium or potassium.
  • the anionic sulphonate surfactant of the present invention is selected from the group consisting of a sodium or potassium salt of C11-13 branched or linear alkyl benzene sulphonates (LAS), C6-22 primary or secondary paraffine sulphonates (PS), C10-18 methyl ester sulphonates (MES), C6-C24 olefin sulphonates (AOS).
  • LAS alkyl benzene sulphonates
  • PS C6-22 primary or secondary paraffine sulphonates
  • MES C10-18 methyl ester sulphonates
  • AOS C6-C24 olefin sulphonates
  • the level of the anionic sulphonate surfactants in the granular detergent composition of the present invention is from 0.01% to 50%, preferably, from 20% to 50%, more preferably, from 20% to 45% by weight of the granular detergent.
  • the granular detergent composition of the present invention is substantially free of anionic sulphate surfactants.
  • substantially free of anionic sulphate surfactants in the present invention means the level of the anionic sulphate surfactants is less than 0.001%, preferably, less than 0.0001%, more preferably, 0%.
  • a hydrotrope is an essential ingredient of the granular detergent composition of the present invention.
  • Detergent granules containing linear alkyl benzene sulphonate as surfactant tend to gel in contact with water and the sticky gel around the granules makes the granules stick to each other and form clumps.
  • the hydrotropes modify the phase behavior of the sulphonate surfactant to a less sticky and less viscous phase and solubilize the sulphonate surfactant more quickly and consequently substantially avoid the formation of clumps or residues during the washing process.
  • the hydrotropes of the present invention include sulphonic acid, sulphonate salts, polyethylene glycols, polypropylene glycols and mixtures thereof.
  • the preferable ionized-salts are the alkali metal, alkaline earthmetal, alkyl amine and ammonium salts of the sulphonic acid. More preferable salts are selected from the group consisting of sodium, potassium, monoethanolamine sulphonate and mixtures thereof.
  • the hydrotrope is selected from the group consisting of the sulphonic acids and sulphonates of lower chain aromatic hydrocarbons, polyethylene glycols, polypropylene glycols and mixtures thereof.
  • Preferable sulphonate salts for the hydrotrope of the present invention are, sodium xylene sulphonates, sodium toluene sulphonates, sodium cumene sulphonates, alkyldiphenyloxide disulphonate having an alkyl group chain length of from C1 to C10, and mixtures thereof.

  • Cationic surfactants are an essential ingredient of the granular detergent composition of the present invention. It is believed that cationic surfactants have two benefits for obtaining improved cleaning performance of the granular detergent product: surfactant penetration on soils and hardness tolerance. Anionic sulphonate surfactants have negative charges, while soils are generally positive-charged. As a result, the anionic sulphonate surfactants do not penetrate soils as well as positively charged cationic surfactants. Also, in the washing process, anionic sulphonate surfactants tend to precipitate by forming complexes with hardness ions in water such as calcium and magnesium. Thus, the cleaning performance of the granular detergent compositions are reduced.
  • cationic surfactants in combination with anionic sulphonate surfactants tend to form micelles. As the micelles do not interact with the hardness ions, the anionic sulphonate surfactants do not precipitate. Thus, the cleaning performance of the granular detergent compositions are not reduced.
  • Preferable cationic surfactants are quaternary ammonium surfactants.
  • Preferable quaternary ammonium surfactants are selected from the group consisting of mono C6-C16, preferably C6-C10 N-alkyl or alkenyl ammonium surfactants, wherein the remaining N positions are substituted by methyl, hydroxyethyl or hydroxypropyl groups.
  • Another preferred cationic surfactant is an C6-C18 alkyl or alkenyl ester of an quaternary ammonium alcohol, such as quaternary choline esters.
  • the cationic surfactants have the formula: wherein R1 is C8-C18 hydrocarbyl and mixtures thereof, preferably, C8-14 alkyl, more preferably, C8, C10 or C12 alkyl, and X is an anion, preferably, chloride or bromide.
  • the level of the cationic surfactant is from 0.5% to 5%, preferably, from 1 % to 5%, by weight of the granular detergent composition.
  • the granular detergent composition of the present invention is made by a process comprising the step of: (a) mixing the anionic sulphonate surfactant, the hydrotrope and the cationic surfactant; (b) adding other detergent ingredients; (c) drying the detergent mixture from step (b); (d) passing the detergent granules to a coating mixer; (e) providing the water soluble coating material to the coating mixer; and (f) at least partially coating the granules in the coating mixer to from the coated detergent granular composition.
  • Step (a) is to mix the anionic sulphonate surfactant, hydrotrope and the cationic surfactant, adding water, if necessary.
  • the hydrotrope is added to modify the phase structure of the sulphonate surfactant.
  • the anionic sulphonate surfactant is mixed with the cationic surfactant, then the hydrotrope is added because the anionic sulphonate surfactant and the cationic surfactant can form an ion pair complex.
  • the detergent granules preferably contain the anionic sulphonate surfactant and the hydrotrope, in the ratio of the anionic sulphonate surfactant to the hydrotrope from 50:1 to 1:1, preferably, from 25:1 to 5:1.
  • step (b) other detergent ingredients including builders such as carbonates, silicates, zeolites or brighteners are added.
