Definitions

  • Nitrogen-containing polyether-polysiloxane block copolymers processes for their preparation and their use for improving the surface properties of fabrics and fibers
  • the invention relates to nitrogen-containing polyether-polysiloxane block copolymers and to a process for their preparation. It further relates to the use of these polymers as an additive in formulations for the care and cleaning of keratinic fibers, such as hair conditioners, as well as for fabrics, non-wovens and / or fibers of natural and / or synthetic raw materials and textiles such as as a plasticizer.
  • Nitrogen-containing polyether-polysiloxane block copolymers and their use as additives for fabric softening agents are known from the patent literature.
  • WO-A-02/10256 and WO-A-04/042136 describe linear polyamino-polysiloxane copolymers based on silicones and functionalized hydrocarbon radicals in which ⁇ , ⁇ -epoxy-siloxanes react with ⁇ , ⁇ -epoxy-functionalized hydrocarbons Amine units are linked together.
  • the cited documents describe polymers based on tertiary amines (eg N, N, N ', N'-tetramethylhexanediamine) and short-chain epoxy-functionalized hydrocarbons (eg ethylene glycol diglycidyl ether) which contain tetraalkylammonium units in high density.
  • All softener formulations based on polysiloxane polymers of the prior art have in common that even after a single washing of a textile finished with them, the softening property is largely lost. If a textile is treated with such compounds, it will indeed receive a good softness, but the siloxane is easily removable again from the corresponding textile due to its low substantivity, such as by washing operations. However, it is desirable that the siloxane remains on the fabric even after washing and thus the soft touch is not lost.
  • the invention is therefore based on the object to find polyether-polysiloxane polymers which have the desired property profile, in particular a very good hydrophilic soft touch and increased permanence on textiles.
  • a high elasticity of elasticity, reduced tendency to wrinkling and an improved desensitizing tendency, for example during ironing, of a finished product are to be regarded as a further positive characteristic.
  • polyether-polysiloxane block copolymers with tetraalkylammonium units as haircare additives is also known from WO-A-02/10256 and WO-A-04/042136.
  • Human hair is exposed daily to a variety of influences. In addition to mechanical stress caused by brushing, combing, putting up or tying back, the hair is also attacked by environmental influences such as strong UV radiation, cold, wind and water. Also the physiological status (eg age, health) of the respective person influences the condition of the keratin fibers.
  • the treatment with chemical agents changes the structure and surface properties of the hair.
  • Methods such as perming, bleaching, dyeing, tinting, smoothing, etc., but also frequent washing with aggressive surfactants contribute to causing more or less severe damage to the hair structure.
  • perming bleaching, dyeing, tinting, smoothing, etc.
  • aggressive surfactants contribute to causing more or less severe damage to the hair structure.
  • both the cortex and the cuticle of the hair are attacked.
  • the disulfide bridges of cystine are broken up by the reduction step and partially oxidized to cysteic acid in the subsequent oxidation step.
  • Bleaching not only destroys melanin but also oxidizes about 15-25% of the disulfide bonds of cystine with mild bleaching. With an excessive bleaching, it may even be up to 45% (K.F. de Polo, A Short Textbook of Cosmetology, 2000, Verlag für chemische Industrie, H. Ziolkowsky GmbH).
  • the chemical treatments, the frequent washing or the UV irradiation result in adverse mechanical properties for the hair caused by the removal of naturally-eliminated hair follicles or humectants (sebum). It is thus brittle, dry, lackluster, porous and poorly combed.
  • Such commercial hair care products contain mainly alkylammonium-based cationic surfactants, as well as the compounds exemplified in WO-A-02/10256 and WO-A-04/042136, polymers, waxes or oils or silicone oils. The effectiveness of these compounds can be u.a. attributed to a hydrophobization of the hair surface.
  • the compounds should therefore show an improved or at least equally good individual effect, but overall an improved combined effect of mechanical and other properties.
  • linear amino-functional polyether-polysiloxane block copolymers described in greater detail below correspond to the previously defined requirement profiles.
  • the compounds according to the invention also have the advantage that they are free of tetraalkylammonium units, which must be avoided for reasons of toxicity (see, for example, Dr. Peter Hardt, "Environmentally friendly textile softeners"), lecture on the 37th German Dyeing Day in Melliand Textilberichte 9/1990, p 699-706).
