Definitions

  • the present invention pertains to fatty soap containing laundry detergent formulations. More particularly this invention pertains to detergent formulations containing soap and fatty acid N-methyl glucamides for fabric washing use in soft water or in water previously softened, using a water softening formulation based on precipitant builders.
  • the present invention is set against a background of change and urgency in society's attitude as to how the natural resources are used, There is a perception that it may be for the general good of society as well as environment to use natural and renewable feed stocks in consumer products such as laundry detergents. For sometime the detergent industry had been striving to achieve this
  • Soaps of C 12 to Cl 8 chain lengths are very good laundry detergents when used in very soft water. Whereas lower alkyl chain length fatty soaps -coco- are fairly soluble in water, longer chain -tallow- soaps are not very soluble. It is these longer chain soaps that are generally preferred for laundry and textile cleaning applications. Therefore their solubility needs to be improved by the addition of cp-actives. For granular or flaked detergent formulations, it would be desirable to enhance the dissolution of higher chain length soaps in wash liquor. Soap based formulations are very sensitive to water hardness ions with the loss of detergency.
  • soaps formulations built with alkaline materials such as alkali carbonates, silicates, borax and orthophosphate had been produced for use in hard water with limited success and hence were superseded by superior built detergent compositions based on sulphonates and sulphates along with nonionics
  • soap-based formulations can be eliminated to some extent by softening the water prior to washing.
  • a day washing machines can accommodate more than one product such as one for washing and one for softening.
  • machines now are electronically controlled and hence manufactures can be persuaded to incorporate other functional cycles such as water softening cycle if a case can be made.
  • sodium soaps particularly C 14-Cl 8 range are not very soluble in cold water.
  • the inclusion of more water-soluble C 12-Cl 6 fatty acid N-methyl glucamides, as co-actives, would increase the dissolution and solubility of soaps in water, particularly under low temperature wash cycle conditions.
  • soaps In distilled water, soaps, besides being good laundry detergents, generally show higher soil suspending power than sulphonate and sulphate anionics and ethoxylated nonipnics. In this respect soaps containing higher proportions of Cl 8 saturated fatty acid are particularly good.
  • Soaps do not have the corrosive tendencies of more common synthetic detergents and have good emulsifying power.
  • EP 103926, 662115, 551415, 548204, 670884, 670885 US5254281 claims toilet soap bar containing up to 10% glucamides.
  • WO98/05752 claims a laundry detergent bar containing anionic surfactant, soap, and up to 20% glucamides along with polyphosphate.
  • the calcium and magnesium salts of conventional anionic detergents such as sulphonates and sulphates are relatively more soluble compared to the corresponding chain length soaps. Therefore, when formulations based on sulphonate/sulphate detergents built with sequestering builders are dissolved in hard water, the equilibrium shifts towards sequestering builder's side. However, in the case of soap, since their hard water ion salts are very insoluble, the equilibrium shifts towards the soap precipitation side and hence soap based formulations cannot, effectively be built with sequestering builders.
  • the precipitant builders such as alkali carbonates, silicates, ortho- phosphates are preferred. Even so certain amount of hard water ion soaps will precipitate in competition with precipitant builders when used together.
  • the most environmentally friendly builders are sodium carbonate, sodium silicates, and zeolites; of these sodium carbonate is preferred on cost effectiveness basis.
  • Sodium carbonate as a builder for detergent formulations suffers from a number of disadvantages. Firstly the reaction between sodium carbonate and calcium ion, producing insoluble calcium carbonate is slow, especially at low temperatures. The result of this is that, for practical purposes, the acceptable level of reduction in calcium ion concentration is not reached, in relation to the time scale of the wash cycle of certain types of washing machines. Secondly the precipitated calcium carbonate fine particles deposit in the interstices of certain fabrics and cannot easily be washed away.
  • soap based detergent compositions are still more difficult to build with sodium carbonate /calcite mixture.
  • alkali metal fatty acid salts react faster with divalent metal ions than the reduction of free metal ions by the action of crystallisation seed and the calcium salts of higher chain length saturated fatty acids are less soluble than calcium carbonate. Therefore, unlike calcium sulpfonate or sulphate detergents, calcium soaps once formed do not go into solution during wash cycle, hence as a builder sodium carbonate / calcite mixture is ineffective for soap based formulations.
  • This invention provides a detergent mixture containing a) C 10-Cl 8 soap and b) ClO-Cl 8 fatty acid N-methyl glucamides for washing in soft water or in water previously softened using a precipitant builder.
  • the detergent actives are naturally derived and highly biodegradable.
  • the preferred glucamides are C 12-Cl 4 fatty acid - coco - derived. They are, besides being good cleaners on their own right, being more soluble than soap would assist in the dissolution of soap in water in low temperature and in the dissolution of soap from formulated products. Being non-ionic in nature they would also have calcium soap dispersing effect and hence prevent any residual calcium soap deposition on fabrics.
  • the level of glucamides in the active mixture could be from 11-60%, preferably from 21-60%
  • the soap used can be based on ClO to C18 fatty acids such as coco, tallow, palm oil, palm kernel oil, hardened tallow, hardened palm oil and mixtures thereof.
  • the water softening mixture is based on alkali carbonates such as sodium and potassium carbonates, sesqui-carbonates or bi-carbonates and mixtures thereof and finely divided calcite.
  • alkali carbonates such as sodium and potassium carbonates, sesqui-carbonates or bi-carbonates and mixtures thereof and finely divided calcite.
  • the calcite particle size wiil be below 20 microns, particularly from 0.01 to 5 microns.
  • the level of calcite particles would be 10-50 % of the mixture.
  • calcite is used to mean either calcite itself or any other water insoluble crystalline water insoluble calcium carbonate mineral.
  • Auxiliary water softening materials that can be incorporated in the water softening mixture include alkali silicates, zeolites and aluminosilicates.
  • the detergent mixture can further include an auxiliary surfactant component to improve the performance further, which comprises anionic and non-ionic surfactants other than soap and glucamides. If present such auxiliary surfactants will, typically, be present in an amount less than 30% of the total active mixture.
  • Such auxiliary surfactants include C 12-Cl 8 alkyl sulphate, Coco alcohol EO4-EO12 ethoxylates, coco alkyl ⁇ polyglucosideSj coco mono and di ethanolamides, their ethoxylates and mixtures thereof.
