  • the present invention relates to the use of these specific mixtures as defined herein for boosting the cleaning efficacy of a textile treatment composition and/or for reducing or even preventing the yellowing of textiles.
  • the present invention relates to a method for boosting or improving the cleaning efficiency of a textile treatment composition and/or reducing the yellowing of textiles and/or preventing the yellowing of textiles by adding an effective amount of the specific boosting/anti-yellowing compositions as specified herein comprising at least one first boosting agent (alkanediols) in combination with at least one further (second) boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone, to said textile treatment composition.

  • second boosting agent selected from the group consisting of glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin or tropolone
  • Changes in the colour impression of washed, that is to say clean, textiles can also be based, on the one hand, on the fact that dye components are removed from the textile by the washing process, so-called “fading”, and on the other hand, dyes detached from differently coloured textiles can deposit on the textile, so-called “discolouration” or “dye transfer”.
  • textile articles can show a discolouration of the fabric caused by repeated use/wearing, laundering/washing or dirt, staining and aging. Further causes of discolouration are exposure to light, air, soil, and the natural degradation of the fibres over time. White or bright materials are often subject to greying or yellowing. However, it is desired that textiles keep their colour appearance.
  • whitening agents such as bleaching agents such as for example sodium hypochlorite, optical brighteners (or optical brightening agents (OBAs) or fluorescent whitening agents), greying inhibitors, ultraviolet light protection agents, and the like.

  • Another approach is based on the use of hueing dyes or of bluing dyes such as azo dyes, triaminotriphenyl methane compounds, triphenyl methane compounds and anthraquinone colourants in order to optically neutralize the yellow colour appearance of the textile.
  • Textiles treated with the textile treatment compositions according to the present invention show a considerably reduced yellowing even when stored for a long time compared to formulations not comprising the mixtures of 1 ,2-heptanediol or 2,3-heptanediol or a mixture comprising 1 ,2-heptanediol and 2,3-heptanediol or of the at least one alkanediol as specified herein with glyceryl caprylate, 4-hydroxyacetophenone, ethyl hexyl glycerin and/or tropolone as boosting compositions as specified herein.

  • yellowing can be caused by contamination through consumer products such as cosmetics e.g., perfumes, body lotions, make-up, and the like.

This effect is also referred to as “phenolic yellowing” or “elusive yellowing”.

  • Another reason for yellowing are, for example, iron containing stains, such as rust, or blood. Remaining iron can cause permanent yellowing of fabrics upon oxidation. However, any residual chemicals left on textiles due to improper cleaning might contribute to the yellowing during heat treatment.

  • Enzymes are known as effective chemicals for use with detergents and other cleaning agents to break down soils. Enzymes break down soils, make them more soluble, and enable surfactants to remove them from a surface to provide enhanced cleaning of a substrate. Specifically, enzymes can provide desirable activity for removal of, for example, protein-based, carbohydrate-based, or triglyceride-based stains from substrates such as textiles. In addition, enzymes also help to improve wash results at lower temperatures. As a result, enzymes have been used for various cleaning applications in order to digest or degrade soils such as grease, oils (e.g. vegetable oils or animal fat), protein, carbohydrate, or the like. For example, enzymes may be added as a component of a composition for laundry, textiles, ware washing, cleaning- in-place, cleaning drains, floors, carpets, medical or dental instruments, meat cutting tools, hard surfaces, personal care, or the like.
