Definitions

  • the invention relates to water-containing skin and hand cleaning agents, in particular "waterless hand cleaners" with improved dermatological compatibility and the use of the agents for removing extreme dirt.
  • Skin and hand cleaning agents are used extensively in industry, especially where stubborn soiling occurs, which is caused by paints, greases, oils, lubricants, metal dusts, graphite, soot and others. are caused.
  • Such cleaning agents are known per se as so-called coarse hand cleaners (cf. H. Tronnier, J. Kresken, K. Jablonski, B. Komp, "Haut undb”, Grosse Verlag, Berlin, pp. 75-108 [1989]).
  • coarse hand cleaners cf. H. Tronnier, J. Kresken, K. Jablonski, B. Komp, "Haut undb”, Grosse Verlag, Berlin, pp. 75-108 [1989]
  • These usually preparations which contain an abrasive, surfactant / surfactant mixtures, thickeners and, if appropriate, auxiliaries for regulating the consistency, appearance, odor and stability, such as pigments, fragrances, stabilizers and preservatives.
  • organic solvents are added to these preparations, e.g.
  • waterless cleaners available on the market, the good cleaning action of which is based primarily on the abovementioned organic solvents, in particular petrol, kerosene, short-chain paraffin oils.
  • Commercial "waterless cleaners” have the following composition:
  • Petroleum distillates 35.0 to 45.0% by weight
  • Trideceth-9 1.0 to 5.0% by weight propylene glycol: 1.0 to 5.0% by weight Petrolatum: 1.0 to 5.0% by weight

  • WO 99/06021 describes water-containing "waterless handcleaner” formulations which have a water content of 75 to 99% by weight, up to 25% by weight of a fatty acid ester or mixtures of such esters and at least one surfactant. Formulations of this type are a significant improvement over the previously mentioned products containing organic solvents, in particular from a toxicological point of view. Nonetheless, the improved skin tolerance and the improved protection against drying out of the skin went hand in hand with a loss of cleansing action in comparison to these solvent-containing "waterless cleaners" or Coarse hand cleaner containing solvents.
  • DE 4424210 A 1 describes water-free shower oils which contain at least 45% by weight of oil selected from the group of oils with a high content of triglycerides, saturated and / or unsaturated fatty acids, such as soybean oil, sunflower oil, wheat germ oil, and a maximum of 55% by weight.

  • Water-containing shower preparations are known from EP 0769292 A 1, with rapeseed oil or rapeseed oil derivatives being used as skin care components in addition to surfactant mixtures. Because of the lack of cleaning power, these agents are also unsuitable as coarse hand cleaners, in particular also because such shower preparations have to meet a different requirement profile with regard to consumer acceptance than with coarse hand cleaners, which focus on the cleaning performance of the product.
  • DE 19748 921 A1 relates to water-containing liquid, pasty or cream-shaped hand cleaning agents, in particular coarse hand cleaning agents with a rubbing agent, which have a content of 10 to 30% by weight of at least one vegetable oil, selected from the group consisting of triglycerides, saturated and / or unsaturated fatty acids , from 10 to 30% by weight of at least one surfactant from the group consisting of fatty alcohol ethoxylates, fatty alcohol ether sulfates and / or castor oil sulfonates and 10 to 65% by weight of water, in each case based on the composition of the cleaning agents.
  • these compositions contain 1 to 30% by weight of at least one abrasive in the composition.
