Definitions

  • the present invention relates to the general field of laundering. More specifically, this invention relates to the delivery of perfume to fabrics which are washed or treated.
  • An even more desirable method for delivering perfume of laundered fabric would be one which provides for protection of the perfume through the washing process and hence delivery of the perfume to fabric in essentially its original state.
  • Such a method must allow for prevention of dilution, degradation or loss of the perfume during the wash cycle of the laundry process. This is done by utilizing a system that releases the perfume in the drying process or later after the perfume has been delivered to the fabric. Preventing release of perfume during the washing process involves very different and more complex technology.
  • perfume microencapsulation comprises a capsule core which is coated completely with a material which may be polymeric.
  • the perfume is delivered to fabric via the microcapsules and is then released by rupture of the microcapsules such as would occur with manipulation of the fabric.
  • a problem with this method is that it takes a certain amount of effort to break the microcapsules.
  • This system is however limited in that it is said to be designed for use in a rinse mode only, i.e. it is not suitable for use in a through the wash mode.
  • Another object of the invention is to provide a system which will gradually release the perfume over a long period of time, after deposition on the fabrics and after the fabrics are dry.
  • the system will protect the perfume and deliver it to fabrics when it is used in a wash liquor which comprises clay.
  • any perfume can be used according to the present invention; it can be relatively simple in its composition or can contain complex mixtures of natural and synthetic chemical compounds which are all chosen to provide any desired odor. Therefore, in its broadest expression, a perfume suitable for use herein is any material which exudes a pleasant or otherwise desirable odor when it is applied to fabrics.
  • Some perfumes which are suitable for use in detergents or fabric treatment compositions are commercially available. Others are described for instance in S. Arctander, Perfume Flavors and Chemicals, Vols. I and II, Author, Montclair, N.J. and the Merck Index, 8th Edition, Merck & Co., Inc. Rahway N.J.
  • the perfume will represent from 20% to 80% by weight of the total perfume carriage and delivery system (hereinafter referred to as the system).
  • the system contains from 40% to 60% by weight of the system of perfume, preferably 50%.
  • the hydrophobic solid compound is the hydrophobic solid compound
  • the system according to the present invention also comprises a hydrophobic solid compound which has a melting point of from about 30 C to about 120°C.
  • the melting point of the hydrophobic compound influences the melting point of the system, and the melting point of the hydrophobic solid is to be adapted so that the system is solid at ambient temperature but liquid or fluid at wash temperature. Accordingly, the man skilled in the art will need to adapt this parameter according to the climate and washing habits in a given country.
  • hydrophobic it is meant that the compound is insoluble in water but miscible with the perfume defined hereinabove. This way, the compound will "protect” the perfume by retaining it in a hydrophobic environment.
  • the system will be in a fluid state, due to the warm temperature of the wash water.
  • the system will then form an emulsion in the wash water and deposit on the fabrics, as explained hereinafter.
  • the hydrophobic compound which still retains the perfume, will "freeze on the fabrics" because of the cold water which is used for rinsing; this way, a very thin layer of the system will be entangled in the fibres of the fabrics, which will not be removed by subsequent rinses.
  • the perfume will be slowly released from the fabrics by simple diffusion through the hydrophobic compound; this diffusion will be more or less rapid depending on the proportion of hydrophobic solid to perfume.
  • the system can also be designed so as to release perfume from the fabrics even long after they have been washed or treated.
  • the amount of the hydrophobic solid can therefore be adapted by the man skilled in the art, keeping in mind that the higher the amount of hydrophobic solid in the system, the more the perfume is protected, but the less the system disperses in the wash liquor. When a high proportion of hydrophobic solid is used, a slow and durable release of the perfume is obtained.
  • the amount of this hydrophobic solid compound in a system according to the present invention is from about 5% to 50% by weight of the system. Preferred amounts are from 10% to 30% by weight of the system, preferably 15%.
  • Suitable compounds according to the above definition include waxy materials and fats. Such materials may be from mineral vegetal, animal or synthetic origin.
  • Example include waxes from the petrochemical industry, polyethylene waxes, bees wax, vegetal wax, triglycerides and the like. Highly preferred are mineral waxes from the petrochemical industry.
  • the system according to the invention also comprises a C 8 -C 20 alcohol, or an ester thereof with a C 2 -C 4 carboxylic acid, or mixtures thereof.
  • Preferred compounds are tallow alcohol or myristyl alcohol.
  • This compound is incorporated in the system so as to allow it to better disperse in the wash water. Indeed, it has been observed that the incorporation of this compound in appropriate amounts allows the system to form an emulsion in the wash water upon agitation.
  • the above balance also depends on the amount of hydrophobic material (defined hereinabove) which is incorporated. Indeed, the hydrophobic material tends to protect the perfume but also tends not to disperse very well. It has been observed that the C 8 -C 20 alcohol or ester thereof with C 2 -C 4 carboxylic acid or mixtures thereof, are to be incorporated in amounts of from 5% to 50% by weight of the total system, preferably from 5% to 25% by weight, preferably 10%.
  • the amphiphile polymer is amphiphile polymer
  • a fourth essential component is an amphiphile polymer which will promote the deposition of the dispersed system on the fabrics during the wash, provided that the system is used in a wash liquor which contains clay.
  • Suitable polymers for such a purpose are amphiphile polymers derived from such monomers as ethylene oxide, terephtalate propylene oxide, acrylamide, acrylic acid and other polymers.
  • polyethylene oxide/polypropylene oxide block copolymers commercially available under the trade name PLURONIC (R) from BASF.
  • polymers are incorporated herein in amounts from 5% to 50% by weight of the total system, preferably from 15% to 35% by weight, preferably 25%.
  • the perfume carriage and delivery system according to the present invention can be made by mixing together the required ingredients; It is preferred to mix the hydrophobic solid together with the C 8 -C 20 alcohol or ester thereof with a C 2 -C 4 carboxylic acid, at a temperature above the melting point of the hydrophobic solid; the amphiphile polymer is then added, preferably at such a temperature.
  • the mixture can be left to completely cool down as such, so as to form a block; in a preferred embodiment however, the mixture will be pellitized.
  • the perfume carriage and delivery system according to the present invention can be used in many different ways; It can be used as such as a laundry additive, for laundry detergent or other fabric treatment compositions which comprise clay; Indeed, as mentioned hereinabove, the presence of clay in the wash liquor is key to a satisfying performance of the system according to the present invention.
  • Clays are conventionally used in the field of detergency, mainly for the purpose of providing softening benefits to fabrics; such clays typically are hectorites or montmorillonites and the like.
  • This agglomeration can be made by any agglomerating technique, and these are well known to the man skilled in the art.
  • the system according to the present invention will not only be agglomerated with clay, but also with a clay-flocculating polymer which will enhance the performance of the system.
  • Suitable clay flocculating polymers are well known to the man skilled in the art, and are described for instance in EP-A-0 299 575, EP 0 313 146 and EP 0 328 182.
  • a system according to the present invention is prepared by mixing together
  • the wax is heated to a temperature of about 70 C, and the tallow alcohol is added while stirring; the polymer is then added, also while stirring.
  • the mixture is then left to cool to a temperature of about 50° C, and the perfume is added.
  • the mixture is then pellitized, and pellets of a system according to the invention are obtained which comprise
  • a laundry additive comprising a system according to the present invention is obtained by mixing 635 g of clay (High CEC Ca Montmorillonite) with 10 g of polyethylene oxide MW 300 000) (clay-flocculating polymer) in an EIRICH mixer. 200 g of the system of example 1 are then added under high shear mixing, and 155 ml of water are subsequently added. A coagglomerate is then obtained comprising a system according to example 1.
  • a granular detergent composition is made which comprises
