Definitions

  • the invention relates to fabric treatment compositions comprising sulfonated tannins, surfactants, and perfume.
  • the invention further relates to a process of making and using same.
  • Fabric treatment compositions used in the laundry process provide benefits to fabrics such as providing a pleasant smell. Such pleasant smell is typically provided by perfumes.
  • perfumes A problem in the field is that much of the perfume is either not deposited or rinsed away during fabric treatment. Because perfumes are expensive components, encapsulation can be used in order to improve the delivery of the perfume during use. Unfortunately, encapsulation processes are time consuming and expensive as they typically require chemical reactions such as extensive crosslinking and/or result in capsules that over-protect the perfume as such capsules typically require a high energy input to release their active - for example pressure, temperature and/or electromagnetic radiation.
  • Such encapsulates' shell typically only protects the benefit agent and, on its own, provides no active value and may even leave a residue when a product containing the encapsulate is used.
  • Deposition aids can also be used but typically only improve the deposition of a single specific perfume raw material.
  • a deposition aid which can be processed into the fabric treatment composition even when little energy is provided to the system, for example when only low shear mixing, needed to ensure homogeneous distribution of the perfume deposition aid throughout the composition, is provided.
  • Such fabric treatment compositions comprising perfume deposition aid and methods of making and using same are provided herein.
  • WO2017/0088798 relates to cleaning compositions comprising tannins to mitigate malodors without imparting color to an article.
  • the invention relates to fabric treatment compositions comprising from 0.01% to 5% sulfonated tannins, from 0.1% to 7% of dispersed perfume and from 0.1% to 50% of surfactants, and processes for making and using same.
  • Such treatment compositions provide improved perfume deposition and/or release from treated fabrics.
  • such compositions are easy to process as a result of improved solubility of the sulfonated tannins into the treatment composition.
  • the term "fabric treatment composition” is a subset of cleaning and treatment compositions that includes, unless otherwise indicated, granular or powder-form all-purpose or "heavy-duty” washing agents, especially cleaning detergents; liquid, gel or paste-form all-purpose washing agents, especially the so-called heavy-duty liquid types; liquid fine-fabric detergents; liquid cleaning and disinfecting agents, fabric conditioning products including softening and/or freshening that may be in liquid, solid and/or dryer sheet form; as well as cleaning auxiliaries such as bleach additives and "stain-stick” or pre-treat types, substrate-laden products such as dryer added sheets, dry and wetted wipes and pads, nonwoven substrates, and sponges; as well as sprays and mists. All of such products which are applicable may be in standard, concentrated or even highly concentrated form even to the extent that such products may in certain aspect be non-aqueous.
  • solid includes granular, powder, bar and tablet product forms.
  • fluid includes liquid, gel, paste and gas product forms.
  • component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.
  • the fabric treatment composition comprises from 0.01% to 5%, preferably from 0.02% to 3%, more preferably from 0.03% to 1.5%, most preferably from 0.05% to 0.5% of sulfonated tannins.
  • sulfonated tannins we herein mean tannins comprising a sulfite (-SO 3 - ) functional group. It was surprisingly found that sulfonated tannins improve the deposition of perfume onto fabrics and hence improve freshness of fabrics treated with the fabric treatment compositions according to the present invention. As such, sulphonated tannins act as perfume deposition aids.
  • the sulfite functional group of sulfonated tannins enable said tannins to be easily processed in an aqueous intermediate and/or fabric treatment composition in case said fabric treatment composition comprises water.
  • sulfonated tannins reduce manufacturing complexity of fabric treatment compositions.
  • Tannins are polyphenolic secondary metabolites of higher plants, and are either galloyl esters and their derivatives, in which galloyl moieties or their derivatives are attached to a variety of polyol-, catechin- and triterpenoid cores (gallotannis, ellagitannins and complex tannins), or they are oligomeric and polymeric proanthocyanidis that can possess interflavanyl coupling and substitution patterns (condensed tannins). More details on the classification of tannins can be found in K. Khanbabaee, T. van Ree, Tannins: Classification and Definition, The Royal Society of Chemistry 2001, pages 641-649 .
  • Gallotannins are all those tannins in which galloyl units are bound to diverse polyol-, catechin- or triterpenoid units.
  • Ellagitannins are those tannins in which at least two galloyl units are C-C coupled to each other, and do not contain a glycosidically linked catechin unit.
  • Complex tannins are tannins in which a catechin unit is bound glycosidically to a gallotannin or an ellagitannin unit.
  • Condensed tannins are all oligomeric and polymeric proanthocyanidins formed by linkage of C-4 of one catechin with C-8 or C-6 of the next monomeric catechin.
  • Sulfonated tannins can be prepared using different processes. One suitable process to obtain sulfonated tannins is described in the EXAMPLES.
