Definitions
- the present invention relates to the use of amine oxide surfactants in cleaning compositions and more particularly to their ability to remove stains, soils or combinations thereof from carpets and fabrics.
- Carpets produced from synthetic or natural fibers and mixtures thereof are commonly used in residential and commercial applications as a floor covering.
- Various types of fibers can be used in making ca ⁇ ets such as polyamide fibers, polyester fibers as well as wool, cotton or even silk.
- carpets as well as fabrics are all prone to soiling and staining when contacted with many household items.
- Foods, grease, oils, beverages in particular such as coffee, tea and soft drinks especially those containing acidic dyes can cause unsightly, often dark stains on ca ⁇ ets and fabrics.
- ca ⁇ et fibers may become soiled as a result of dirt particles, clay, dust, particulate soils in general, coming into contact with and adhering to the fibers of the ca ⁇ ets.
- These latter soils often appear in the form of a diffuse layer of soils rather than in the form of spots and tend to accumulate particularly in the so called "high traffic areas" such as near doors as a result of intensive use of the carpets in such areas.
- ca ⁇ et cleaning compositions described in the art for removing stains and soils from ca ⁇ ets As well as a number of fabric cleaning compositions described in the art for removing stains and soils from fabrics.
- these compositions do not satisfactorily meet the consumer's needs regarding their cleaning performance on different types of stains and soils.
- ca ⁇ et cleaning compositions are not fully satisfactory on removing particulate stains and/or greasy stains, especially in the so called "high traffic areas" of ca ⁇ ets.
- the object of the present invention is to provide improved stain removal performance, in a manner which is applicable to a variety of cleaning compositions, i.e. compositions being either in a liquid form, or in a powder form, or in a granular form, and to a variety of applications like ca ⁇ ets and/or fabrics cleaning applications.
- amine oxide surfactants according to the formula R1R2R3NO, wherein each of R1 , R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms, in a cleaning composition.
- said amine oxide surfactants allow to deliver improved stain removal performance on a variety of stains including particulate stains, greasy/oily stains like chocolate, sphagetti sauce, mayonnaise as well as bleachable stains like coffee, tea, and enzymatic stains like blood.
- the present finding is applicable both in laundry cleaning application, especially in laundry pretreatment, and in carpet cleaning application.
- An advantage of the present invention is that it is applicable to all ca ⁇ et types, especially delicate natural fibers and is also safe to all ca ⁇ et dye types, particularly sensitive natural dyes used therein.
- the present invention is particularly suitable for the cleaning of upholstery and car seat coverings.
- compositions to be used according to the present invention may be applied directly on the ca ⁇ et without causing damage to the ca ⁇ et.
- cleaning action of the invention commences as soon as the ca ⁇ et cleaning composition has been applied to the surface.
- the use of the ca ⁇ t cleaning compositions of the present invention does not necessarily require rubbing and/or brushing of the carpet.
- a further advantage of the present invention is that it is applicable to all types of fabrics, especially delicate fabrics upon pretreatment conditions, e.g., when applied onto the fabrics even for a prolonged period of contact, before said fabrics are washed.
- the present invention encompasses the use of an amine oxide surfactant according to the formula R1 R2R3NO, wherein each of R1 , R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms, in a cleaning composition, to improve the stain removal performance of said composition.
- the present invention further encompasses a method of cleaning a carpet wherein a composition comprising an amine oxide surfactant according to the formula R1 R2R3NO, wherein each of R1, R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms, is applied to said ca ⁇ et, wherein said carpet is then optionally rubbed and/or brushed, and wherein said composition rs then removed from said ca ⁇ et.
- a composition comprising an amine oxide surfactant according to the formula R1 R2R3NO, wherein each of R1, R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms
- the present invention also encompasses a method of pretreating fabrics with a composition comprising an amine oxide surfactant according to the formula R1R2R3NO, wherein each of R1, R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms, said method comprising the steps of applying said composition in its neat form onto the fabric, and allowing said composition to remain in contact with said fabric before said fabric is washed.
- a composition comprising an amine oxide surfactant according to the formula R1R2R3NO, wherein each of R1, R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms
- the present invention relates to the use of amine oxide surfactants according to the formula R1R2R3NO, wherein each of R1, R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl group of from 1 to 30 carbon atoms, in a cleaning composition to improve the stain removal performance of said composition.
- compositions to be used according to the present invention comprise an amine oxide surfactant or mixtures thereof.
- Suitable amine oxide surfactants to be used herein are according to the following formula R1 R2R3NO wherein each of R1 , R2 and R3 is independently a saturated substituted or unsubstituted, linear or branched alkyl groups of from 1 to 30 carbon atoms, and preferably of from 1 to 20 carbon atoms.
- Particularly preferred amine oxide surfactants to be used according to the present invention are amine oxide surfactants having the following formula R1R2R3NO wherein R1 is a saturated linear or branched alkyl group of 1 to 30 alkyl group, preferably of 6 to 18 alkyl group, more preferably of 6 to 14, most preferably of 6 to 10 and wherein R2 and R3 are independently substituted or unsubstituted, linear or branched alkyl groups of from 1 to 4 carbon atoms, preferably of from 1 to 3 carbon atoms, and more preferably are methyl groups.
- R1 is a saturated linear or branched alkyl group of 1 to 30 alkyl group, preferably of 6 to 18 alkyl group, more preferably of 6 to 14, most preferably of 6 to 10 and wherein R2 and R3 are independently substituted or unsubstituted, linear or branched alkyl groups of from 1 to 4 carbon atoms, preferably of from 1 to 3 carbon atoms, and more preferably are
- said amine oxide surfactants are pure-cut amine oxide surfactants, i.e., a pure single amine oxide surfactant, e.g. C ⁇ N,N- imethyl amine oxide, as opposed to mixtures of amine oxide surfactants of different chain lenghts.
- Suitable amine oxide surfactants for use herein are for instance pure cut C8 amine oxide or pure cut C10 amine oxide or pure cut C14 amine oxide, natural blend C8-C10 amine oxides as well as C12-C16 amine oxides.
- Said amine oxide surfactants may be commercially available from Hoechst or Stephan.
- said amine oxide surfactants allow to deliver improved stain removal performance on a variety of stains/soils including particulate stains, greasy/oily stains, bleachable stains and/or enzymatic stains.
- stains in particular particulate stains and/or greasy/oily stains and/or bleachable stains and/or enzymatic stains achieved by using a cleaning composition comprising said amine oxide surfactants
- a cleaning composition comprising said amine oxide surfactants
- another surfactant like for instance alkyl sulphate instead of said amine oxide surfactants.
- articulate stains it is meant herein any soils or stains of particulate nature that can be found on ca ⁇ ets or fabrics, e.g., clay, dirt, dust, mud, concrete and the like.
- greasy/oily stains any soils or stains of greasy/oily nature that can be found on ca ⁇ ets or fabrics, e.g., make-up, lipstick, dirty motor oil and mineral oil, greasy food like mayonnaise and spaghetti sauce.
- bleachable stains any stains on ca ⁇ ets or fabrics that can be oxidised by bleach, e.g. coffee, tea, wine, grass or fruit juice.
- enzymatic stains any soils or stains of enzymatic nature that can be found on carpets or fabrics, e.g., blood.
- compositions herein further comprise a source of active oxygen
- the presence of said amine oxide surfactants improves the chemical stability of said compositions. Indeed, we have observed that improved chemical stability, i.e., lower decomposition of the bleach and the bleach activator, if present, is obtained by adding such an amine oxide surfactant. It is believed that such stability is due to the capacity of the amine-oxide surfactants to limit interactions between the bleach and the bleach activator, if present, possibly through emulsification. It is believed that this stabilising effect is matrix independent.
- said amine oxide surfactants especially pure-cut short chain (C6-C10) amine oxide surfactants have the advantage to reduce the amount of residues left onto fibers being treated with a composition comprising them. Also, the residues left after said composition comprising them has performed its cleaning action are partially in a crystalline form. Indeed, it has been observed that with the compositions according to the present invention comprising said amine oxide surfactants, especially pure-cut amine oxide surfactants, more than 90%, preferably more than 95%, of the residues left onto the fibers are crystals (generally lamellar and/or needle- shaped) with an average particle surface bigger than 300 ⁇ 2 .
- an advantage of the finding of the present invention is that it is applicable in different cleaning processes including ca ⁇ et cleaning and fabric cleaning especially fabric pretreatment.
- such cleaning compositions comprising said amine oxide surfactants are particularly useful as laundry pretreaters, i.e. in a process where said composition is applied in neat form onto soiled portions of fabrics before said fabrics are washed in a separate, typical laundry operation.
- said composition in neat form is left to act on said portions for a period of time before the fabrics are washed in said laundry operation.
- said composition in neat form is not left to dry onto said portions.
- said period of time is in between 1 minute to several hours, more preferably 1 minute to 1 hour, more preferably 1 minute to 30 minutes and most preferably 2 to 10 minutes.
- said pretreatment process may additionally involve rubbing and scrubbing. It has been observed that in such a pretreatment process, the presence of said amine oxide surfactants improves the stain removal performance on a variety of stains.
