Definitions

  • Fabric softening actives are known to be added to laundry applications, for example, in order to provide softer fabrics, to reduce or eliminate static, to reduce or eliminate wrinkles and to enhance in-wear comfort.
  • fabric softening actives have been used to provide benefits on fabrics such as clothes. These fabric softening actives are typically added in the rinse cycle of a laundering operation or applied on a sheeted substrate and used in a cloth dryer.
  • a fabric care composition containing a protein is especially beneficial for cleaning fabrics, such as reducing fabric "dinginess", as well as unexpectedly providing consumer desirable benefits to the washed fabric, such as softness, reduced wrinkling, enhanced moisture retention, and a reduced electrostatic charge.
  • the fabric softener product form has also been surprisingly found to be an effective way of delivering protein, such as sericin, onto fabrics for potential skin protection benefits upon wearing. None of the existing art provides all of the advantages and benefits of the present invention.
  • the present invention relates to a fabric care composition containing a fabric softening active and a protein, wherein from about 20% to about 40% of the amino acid in the primary structure of the protein is serine, and wherein the pH of the fabric care composition is less than 7 at 25°C.
  • the protein is preferably sericin.
  • alkyl means a hydrocarbyl moiety which is straight or branched, saturated or unsaturated. Unless otherwise specified, alkyl moieties are preferably saturated or unsaturated with double bonds, preferably with one or two double bonds. Included in the term “alkyl” is the alkyl portion of acyl groups.
  • the fabric care composition in the present invention may add softening effects to fabrics, reduce wrinkle formation on fabric, reduce electrostatic on the fabric surface, enhance moisture retention, and increase in-wear comfort. While not intended to be limited by theory, it is believed that the fabric care composition of the present invention helps deposit protein actives onto fabrics due to the anionic nature of the softener composition.
  • a protein such as sericin is an effective moisture retention agent to negate the effect of the softener effect which is known to reduce the water absorption ability of fabrics. Moisture retention is important in reducing wrinkles, and preventing electrostatic charge build-up, while keeping the softening effect of the softener. While not intended to be limited by theory, it is also believed that the protein protects the human skin through skin or surface deposition, and as a result there are skin care and skin mildness benefits.
  • the protein has a hydroxyl group in the molecule (-OH).
  • hydroxyl group traps water
  • the protein has a high water absorption in the molecule.
  • the fabric feels soft to the skin.
  • the wrinkles on the fabric surface is reduced and the formation of electrostatic charge on the fabric is reduced.
  • the percentage of the serine in the primary structure of the protein is lower than 20%, the protein does not have a high water absorption. If the amount is above 40%, when synthesized by the recombinant method, the rate of the synthesis reaction becomes slow, and a sufficient amount of the recombinant protein may not be produced. Therefore, the percentage of the serine in the primary structure of the protein should be from about 20% to about 40%.
  • the fabric care composition of the present invention also reduces the yellow "dingy" hue left on fabrics.
  • Yellow dinginess is a yellow hue left on the fabric surface even after cleaning, and is especially common with cotton fabrics. If the lipid residue left on the fabric surface becomes oxidized upon contact with air, the lipid residue color turns yellow via polymerization and decomposition. As the protein prevents the lipid residue from becoming oxidized on the fabric surface, yellow dinginess on the fabric is substantially reduced.
  • the protein used in the present invention is unique in that it has a high content of serine amino acid, is chemically stable under laundering conditions, and is effective in preventing oxidation. Furthermore, the fabric care composition containing the protein may reduce allergic reactions for skin-sensitive individuals who comes into contact with fabric treated with the fabric care composition of the present invention since the protein is uniquely known to be compatible with human skin. Also, if skin- sensitive individuals come into direct contact with the fabric care composition of the present invention, such as when manually handling the fabric treated with the composition or handling the composition directly, the fabric care composition is mild to the hands.

Any type of protein which contains from about 20% to about 40% of serine as the amino acid in the primary structure, can be used for the present invention.

  • ClogP The "calculated logP” (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding.
  • ClogP values which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention.

The closer to uni-lamellar the appearance, the better the compositions seem to perform.
