Definitions

  • the invention relates to sustainable surfactant mixtures for use as detergents and cleaning agents for hard surfaces and/or textiles and fibers which contain surfactants which are characterized by an exceptionally high proportion of unsaturated, long-chain (>C18) alkyl radicals and are based on vegetable oils from the temperate zone .
  • Detergents and cleaning agents mainly contain surfactants as washing-active substances, molecules that are made up of a hydrophilic and a lipophilic part.
  • the lipophilic part of surfactants comes mainly from fossil or vegetable raw materials.
  • Oils from these tropical plants are used primarily because of their high content of fatty acids with medium alkyl chain lengths C10-C14, whose surfactants are known for good water solubility, positive foaming behavior and high washing power.
  • Desirable for the conservation of natural resources and as a contribution to global climate protection is the use of local and/or regional oils from cultivation areas in temperate zones as raw materials for detergents and cleaning agents, e.g. from geographical Europe.
  • an increased agricultural cultivation of industrial oilseeds in the temperate zones is to be expected, combined with a positive influence on the level of employment, the trade balance, biodiversity, as well as health and the environment.
  • the fatty acid mixtures in question in known formulation concepts have poorer water solubility and poorer cleaning power.
  • anionic surfactants are C12 compounds such as lauryl benzene sulphonates, lauryl ether sulphates or lauryl sulphate based on palm, coconut or petroleum.
  • the complex task of the invention was therefore to formulate detergents and cleaning agents based on surfactants with vegetable raw materials from the temperate zones, on the one hand to shorten the transport routes of the raw materials and on the other hand to reduce the negative effects of palm oil extraction or the use of petroleum to reduce. Cultivation and production of the raw materials should take place regionally as far as possible. Consequently, it was necessary to produce stable agents that contain a predominant proportion of surfactants with alkyl chain lengths of C>18 and are mostly unsaturated, as are primarily found in vegetable oils in the temperate zone.
  • This invention thus makes it possible for the first time to formulate environmentally friendly detergents and cleaning agents based on oils from renewable raw materials from the temperate zones, which also have a pleasant smell even without the use of perfume oils.
