Definitions

  • the present disclosure generally relates to the field of laundry washing and fabric care compositions as well as to home care compositions and methods and uses thereof. More particularly, the present disclosure relates to fabric conditioning compositions, fabric refreshers and liquid laundry detergents comprising highly-branched cyclic dextrin as a malodor control agent and methods and uses thereof.
  • Fabrics can become hard due to repeated washings. Also, after washing, fabrics can have an undesirable smell. To restore their softness, improve their scent, or impart other desirable properties, fabrics are often treated by additional processes that are separate from their washing. The treatments are separate because the fabric-treating compositions are often not compatible with the washing detergent. These additional processes can be done, for example, in the washer during an added cycle, or in the dryer when using a solid composition. For example, it is well known to provide liquid fabric conditioning compositions that soften washed fabrics. Such compositions are typically added to the fabrics in the rinse cycle of the wash process
  • Body odor and/or sweat is one of the most prevalent malodors that consumers seek to address by laundering with various detergents.
  • consumers also use fabric conditioning compositions noted above, e.g., to improve the results or to achieve further benefits.
  • the chemical constituents within body odor predominantly short-chained fatty acids and mercaptans, persist on fabrics post-wear and may sometimes continue to be perceivable after washing with conventional laundry products.
  • perfumes or perfume compositions are used to cover up or reduce malodors on fabrics.
  • perfumes are often very expensive and are, in many cases, not capable to cover malodors sufficiently and long-lastingly.
  • the use of perfumes or fragrance molecules in detergents, fabric conditioning compositions or home care products is further limited due to the restriction of specific fragrances, challenging addition of specific perfume compositions or molecules to the formulation matrix or high concentrations of other necessary compounds.
  • the inventors of the present invention have surprisingly found that adding highly-branched cyclic dextrin compounds (also called cluster dextrins) to (laundry) detergents, fabric conditioning compositions or home care products, such as fabric refreshers, reduces or eliminates the (perception of) malodors from/within the washed or treated fabric(s).

  • the bonds between the glucoses allow cyclic dextrin to have the coil-like structure shown in FIG. 1 , containing a certain volume of void space.
  • the array of each interior space is formed by oxygen atoms that form glycoside bridges with hydrogen atoms. Therefore, the inner surface becomes very hydrophobic, and the specific shape and physico-chemical properties of the voids have structural features capable of absorbing organic molecules or portions of organic molecules that match the shape of the inner space of the cyclic dextrin.
