Definitions

  • the present invention relates to the use of fabric treatment composition comprising a soil release polymer for promoting repellency of allergens from textiles.
  • Fabric treatment compositions such as laundry compositions generally provide several benefits for textiles, the most common being to remove dirt and stains during the wash cycle and also to soften the textile during the rinse cycle.
  • consumers expect more from fabric treatment compositions. Indeed, consumers are, now, looking for compositions providing additional benefits i.e. for compositions which not only provide good cleaning or softening performances, but also which help them, at the same time, to solving their health and environmental problems.
  • allergens are a disorder of the immune system and is due to environmental substances known as allergens.
  • Allergens are commonly found in dust and, specifically, in house dust. In most cases allergens are small soluble proteins or glycoproteins that are able to penetrate the nasal and respiratory mucosae. Allergens can be, for example, derived from pollens, dust mites, animal dander, insects and fungi.
  • inhalant allergens The exposure to inhalant allergens is an important factor in the development of allergic diseases. Indeed, these inhaled allergens, commonly found in many households, are the most common cause of conjunctivitis, asthma and allergic rhinitis in developed countries.
  • allergens accumulate on various indoor surfaces and in allergen reservoirs, such as carpets, upholstery, mattresses and pillows. Clothing accumulates ambient allergens quickly and is an important source and carrier of allergens to homes.
  • Frequent laundering of clothing and bedding are effective methods for removing house dust and allergens from washable items and thus are good methods for reducing allergen exposure and thus for reducing allergy reactions.
  • Soil release polymers are well known ingredients in laundry detergent compositions.
  • US 4, 007, 305 (published Feb. 8, 1977 ); US 4,702,857 (published Oct. 27, 1987 ); EP 0 707 627 (published Apr. 24, 1996 ); EP 991 743 (published Apr. 12, 2000 ) or US 7 087 572 (published Aug. 8, 2006 ) relates to soil-release polymers and/or to their use as ingredients in fabric care compositions.
  • the present invention is based, thus, on the finding that some polymers can impart a benefit to the laundry composition contained it. Indeed, textiles treated with a laundry composition containing a polymeric soil release agents are less prone to retain dust and allergens. Polymer soil release agents have the advantage of promoting the repellency of allergen from textiles. Conveniently, laundry compositions containing such polymers can be applied repeatedly in a normal domestic laundry operation in view of improving repellency of allergen and thus decreasing the contact with allergen leading thus to a better health and less allergenic reaction of consumers using it.
  • the present invention relates to the use of a fabric treatment composition comprising a polymeric soil release agent for promoting repellency of allergens selected from animal dander and house dust mite allergens from textiles.
  • the present invention further relates to a method for repelling allergen selected from animal dander and house dust mite allergens from textiles by contacting the textile with a fabric treatment composition containing the soil release polymer.
  • Laundry treated in accordance with the present invention provides therefore an economical and effective method to reduce allergen exposure and dispersal from various surfaces.
  • the present invention reduces also the probability of the allergen to cause allergic responses in host such as a human being.
  • the present invention relates to the use of a fabric treatment composition comprising polymeric soil release agents for promoting repellency of allergens from textiles.
  • repelency it is meant herein that a textile treated with the polymer according to the present invention has the ability to repel allergen from its surface, i.e. the allergen will be repulsed from the textile surface and will not adhere to its surface.
  • polymers according to the present invention create a sort of coating around the textile fabrics which prevents them for attaching allergens.
  • the polymers help the fabrics to repel and to "squeeze" away the dust and allergens from its surface.
  • the fabrics will not contain any allergen and will be less prone to attract them and to retain them when there are contacted to their surface.
  • repellency it is thus meant herein that the polymeric soil release agents will enhance the repellency benefit.
  • allergen is meant to include any substances that are capable of sensitizing and inducing an allergic reaction in a host such as human being. Allergens which can be removed from textiles and fabrics, in accordance with the present invention, include, animal dander, and house dust mite allergens including house dust mite feces. All of these allergens are often found in house dust.
  • allergens found on clothes As examples of allergens found on clothes, it can be cited, the main mite allergens of the genus Dermatophagoides: Der 1-Der p 1 and Der f 1; Der 2-Der p 2 and Der f 2, allergens which are abundant in mite fecal pellets and body debris.
  • Fel d 1 the most common cat allergen
  • Can f the most common dog allergens, are also illustration of allergens which can be easily repelled from textiles using the polymer of the present invention.
  • the polymer of the present invention can be defined as polymeric soil release agents.
  • polymeric soil release agents it is meant herein polymers having soil release properties, i.e. having the property to enhance the cleaning efficacy of the cleaning composition by improving release of greasy and oil during the laundry process.

  • House dust containing known amounts of allergens derived from dust mites, and cat & dog dander are used.
  • the house dust is artificially spiked with the allergens and milled to get a homogeneous distribution of allergens.
  • Both house dust and allergens are purchased from the Greer Laboratories Ltd.
  • the house dust is applied onto fabrics over a frame (0.3gr/circle). A weight is then applied onto the stain for 1 minute. The dust is then shacked off by placing the swatch up side down on top of a plastic beaker. The beaker is then stroked 3 times on the bench.
  • Table 1 shows the stain removal index (SRI) of an allergenic dust stain applied onto fabrics swatches pre-conditioned with Composition A or B. Values are the mean and standard deviation of three different replicates for each detergent treatment.
