Definitions

  • the present invention relates to liquid compositions, especially to fabric care and fabric conditioning formulations, of transparent optics and viscous consistency, to the use of these compositions as fabric care and fabric conditioning formulations, and to a fabric laundering process using these compositions, especially fabric care and fabric conditioning formulations.
  • the present invention relates to a process for the preparation of such liquid transparent compositions.
  • Liquid fabric treatment compositions containing cationic softening compounds have been known in the art for many years. Such compositions are generally opaque because the cationic fabric softening compound is, for example, only partially dissolved or even crystalline. In particular, this effect also occurs with cationic softening compounds selected from the group of esterquats (EQ). Although specific unsaturated quaternary ester quats are available on the market to produce optically transparent formulations, high concentrations of these particular ester quats and the use of solvents are required to provide clear softener formulations having the desired properties. This, in turn, is disadvantageous in terms of the cost and environmental footprint of such formulations.
  • liquid transparent compositions be viscous without threading for ease of handling and metering.
  • stability of such liquid transparent compositions since not only a consistent application-related quality, but also a long-lasting, visually and olfactory appealing structure of the product is desired.
  • Such compositions are made DE 102014010875 A1 and DE 102015204206 A1 known.
  • the present invention solves the problem of providing transparent and viscous compositions containing a cationic softening compound which at least partially overcome the above-described disadvantages of known formulations.
  • the invention is based on the inventors' surprising finding that the use of special thickeners in combination with certain nonionic emulsifiers makes it possible to provide a transparent and viscous fabric conditioning formulation which has a high storage stability, storage stability meaning that no exudation occurs.
  • a second object of the present invention is a method for treating textiles in which at least one textile is brought into contact with the liquid transparent composition.
  • a third object of the invention is the use of the liquid transparent composition for the care and / or conditioning of textile fabrics.
  • At least one refers to 1 or more, for example, 2, 3, 4, 5, 6, 7, 8, 9 or more. In the context of components of the compositions described herein, this indication does not refer to the absolute amount of molecules but to the nature of the ingredient.
  • at least one emulsifier means, for example, one or more different emulsifiers, i. one or more different types of emulsifiers. Together with quantities, the quantities refer to the total amount of the corresponding designated type of ingredient as defined above.
  • liquid composition describes a composition which the consumer generally regards as liquid at a temperature of 20 ° C. and 1013 hPa. At the molecular level, this means that a liquid composition may have some near-order, but the long-range order is almost completely eliminated.
  • a liquid composition is a composition that provides almost no change in shape but relatively high resistance to volume change.
  • a liquid composition within the meaning of the invention is therefore e.g. a composition consisting of water and common salt or a liquid detergent gel, no liquid composition according to the invention, however, is e.g. Glass.
  • a transparent composition in the context of the present invention is a composition which transmits electromagnetic waves, in this case light from the human-visible spectral range, so that the incident light is hardly reflected, scattered or absorbed.
  • Such compositions are also colloquially referred to as “clear” compositions, which may be used synonymously herein for "transparent”.
  • the pH is determined according to DIN EN 1262: 2003, the standard describing the measurement of the pH of solutions or dispersions of surfactants. According to this standard, the pH is determined by potentiometric measurement with a glass / calomel electrode and a commercial pH meter certainly. The pH measurement is carried out in the temperature range of 20 ° to 25 ° C.
  • the liquid transparent composition is particularly stable. Over long storage periods, the composition remains more transparent than comparison compositions, ie it has a lower NTU value, ie a lower turbidity value, which can be determined according to DIN EN ISO 7027: 1999. Also, the odor remains more pleasant than in comparative compositions, as long as the liquid transparent composition contains as at least one cationic softening compound a compound having at least one ester group. In terms of the pleasant odor, the focus here is particularly on a smell that smells less intensively or not at all of fatty acid. Without wishing to be bound by any particular theory, it is believed that the claimed pH value prevents the hydrolysis of ester groups and advantageously stabilizes the liquid transparent composition. The formation of free fatty acid by the hydrolysis of ester groups is thus avoided.
  • the liquid transparent composition of the present invention contains at least one cationic softening compound, which is advantageously selected from quaternary ammonium compounds.
  • the at least one cationic softening compound is an esterquat based on quaternary triethanol-methylammonium or quaternary diethanol-dimethylammonium compounds.
