Jean Macris and Tee Yong Tan Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia Perfume Delivery System The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845 Ref. 6510/279 The invention is related to a perfume carrier for use in detergent compositions, in particular non-soap detergent compositions, the use of the perfume carriers for perfuming detergents and a detergent composition containing the perfume carrier.
Laundry bars, preferably non-soap laundry bars, are, usually, prepared by mixing at high temperatures (around 90'C) compositions containing minerals, surfactants (detergents) and perfumes. Such mixture is then extruded, conveniently at a high temperature, e.g. at around ooooe The perfume is a key ingredient of the composition because it strongly 10 determines the first choice of the consumer. Because of the high temperatures of preparation of laundry bars, part of the perfume is lost by evaporation in the plant. One way of limiting the perfume loss is to design the perfume using perfumery materials with a low vapour pressure. This way is not fully satisfactory, because it does not avoid completely perfume 15 losses and it limits to a great extent the palette of fragrance materials used by the perfumer in creating perfumes.
*.*The invention in one of its aspects relates to perfume-containing carriers which limit perfume loss during the manufacture of detergent compositions, in particular non-soap detergent compositions, especially laundry bars, i.e. detergent composition bars, and/or increase the perfume storage stability of detergent compositions, in particular of non-soap detergent compositions, especially of detergent powders and aforementioned laundry bars. This effect enables a better perfume delivery of freshly prepared detergent products and also of laundry bars and powders stored under high temperature and high humidity.
Many techniques have been used to improve perfume delivery to fabrics: f, Mey/uz/20.05.1997 Micro encapsulation has been described (USP 4145184, USP 4234627, USP 4096072, USP 4402856, WO 92/18601). The technique is satisfactory, but costs are high.
Perfumes can also be included in a water insoluble matrix (USP 4152272).
Other methods consist in adsorbing perfumes on various porous substrates such as silica, zeolite, clay or polymers. So, USP 4,539,135 discloses a perfume-containing carrier for use in admixture with a particulate detergent composition or an additive to a wash solution separate from the detergent composition. The carrier consists essentially of discrete particles containing at least 90%, by weight, of a clay, in particular of bentonite, and/or a zeolite, and less than about by weight, of surface active detergent compounds and a perfume, which is in the liquid state at ambient temperature and is adsorbed and/or absorbed on said particles.
15 Further, WO94/28107 discloses a perfume delivery composition in the form of particles comprising a solid, water-insoluble, porous carrier which comprises a natural or synthetic zeolite having a nominal pore size of at least 6 Angstroms, a perfume which is releasably incorporated (trapped) in the pores of said zeolite carrier to provide a perfumed zeolite and a matrix coated on said perfumed zeolite comprising a water-soluble composition in which the perfume is substantially insoluble. The matrix forms a protective barrier entrapping and maintaining the perfume within the zeolite's pores.
The matrix comprises from 0% to 80%, by weight, of at least one solid polyol containing more than 3 hydroxyl moieties and from 20% to 100%, by weight, 25 of a fluid diol or polyol in which the perfume is substantially insoluble and in which the solid polyol is substantially soluble. The polyol or diol is selected from the group consisting of glycerol, ethylene glycol, and diglycerol.
Both these disclosures do not overcome the problem of perfume loss by evaporation during the production of detergent compositions at elevated temperatures as outlined at the beginning. Therefore, the object of the present invention is to present a perfume carrier for detergent compositions, in particular for non-soap detergent compositions, which has low loss of perfume, especially at elevated temperatures, e.g;when laundry bars or detergent powders are produced and/or stored.
The present invention now provides a cheap and, in particular, simple means to overcome the drawbacks of the prior art.
The following aspects form the invention: In one aspect, the present invention relates to compositions, in particular granular compositions, enabling a better perfume delivery when introduced into detergents, in particular non-soap detergents, such as laundry bars on detergent powders.
Accordingly, a first aspect of the present invention provides a perfume carrier suitable for use in detergent compositions, in particular non-soap detergent compositions, consisting of 20% to 90% by weight of a solid water insoluble mineral carrier having applied onto the surface thereof a mixture of a perfume composition and 0.1% to 20% of a perfume viscosifier consisting of polyethylene glycol with a molecular weight of 4000 to 20000 that is soluble in water and the perfume composition.
A second aspect of the present invention provides a detergent composition comprising a detergent and a perfume carrier of the first aspect of the present invention as defined above.
This aspect covers a perfume carrier suitable for use in detergent compositions, in I particular in non-stop detergent compositions, containing a solid water insoluble mineral, i.e. inorganic carrier, a perfume (composition) and a water and perfume soluble perfume S8*: viscosifier.
A third aspect of the present invention provides a process for preparing a detergent composition of the second aspect of the invention defined above, said process comprising combining a detergent with a preformed perfume carrier wherein the perfume carrier consists of a solid water-insoluble mineral carrier having applied onto its surface a mixture of a perfume composition and a perfume viscosifier that is soluble in water and the perfume composition and, wherein the mixture is adsorbed onto the surface of the S* carrier.
The role of the solid-carrier ("the mineral") is mainly to produce solid granules by adsorbing a perfume/viscosifier mixture. From 20 to 90%, preferably from 50 to 90%, of any solid carrier chosen among the raw materials normally used in detergent products is usually present. The material of the solid carrier may be silica, a silicate, in particular a clay, a phosphate or any mixtures thereof. The preferred solid carriers consist of bentonite, bentonite/sodium tripolyphosphate (STPP), zeolite, bentonite/zeolite, bentonite/silica.
The term "zeolite" refers to any crystalline aluminisilicate material of natural or synthetic origin having a zeolite structure, e.g. having the general formula: (Na 2 0)x.Al 2 0 3 .(SiO 2 )y.zH 2 0 A preferred zeolite is Zeolite A as produced by Degussa under the trade name HAB Bentonite is a clay, e.g. as sold under the trademark Laundrosil DGA by Slid Chemie or Mineral Colloid by the Benton Clay Company.
Silica is, e.g. produced by Degussa under the trademark Supernat 22S.
Sodium tripolyphosphate is a common raw material used in detergent products; its purpose is mainly to complex calcium ions. A suitable material is produced by Albright and Wilson under the trademark Empiphos STPP.
The term "perfume stands for the required mixture of any perfume materials of synthetic and/or natural origin, which is suitable for perfuming soap bars and detergents.
I0 It can contain (small amounts of) the usual C o *ooo
C
IR:\LIBA]03430.doc:nss solvents and diluents destined for this purpose. Propylene glycol is an example of such solvent.
The term "perfume composition", as used in connection with the present invention, means such solutions of perfume materials.
In the context of this invention, "perfume" and "perfume composition" will be used interchangeably.
The role of the perfume viscosifier is to increase the viscosity of the perfume to such an extent as to decrease its evaporation and to provide better stability. From 1 to of a polyethylene glycol, especially with a molecular weight from 4000 to 20000, more preferably between 2000 and 10000, can be used for this purpose.
The perfume carriers are preferably prepared in form of granulates by spraying a mixture of perfume viscosifier and perfume onto the solid carriers in a granulator, or by simple mixing of the perfume viscosifier/perfume mixture with the solid carriers.
The suitable concentrations w/w) of the components in the perfume carriers are 15 as follows: solid carrier 20-90 50-90 40-60 viscosifier 0.1-20 0.2-5 0.5-3 perfume 1-60 5-50 10-40 An effective amount, of novel perfume carrier, especially about 0,5-20%, should be present in the final product, whereby the concentration of the perfume in the final product should conveniently be 0.1 to about preferably 0.1 to about 2%.

The storage stability of the products was assessed against a product of the same formulation but where the perfume was introduced into the detergent product at a level of 0.2% (B1) and stored at room temperature. The products with B2 were stored 2 weeks at 43°C (for the powder) and 55 0 C (for the laundry bar). The products were then assessed by sniffing. The following results were found: Formulation Stability Stability with laundry bar detergent powder 0.2% of non-protected B1 good good perfume 0.15% of protected B2 equivalent to B1 equivalent to B1 perfume From these results it can be concluded, that the use of the perfume carrier according to the invention increases the stability of the perfume when the material products are stored at higher temperatures, i.e. no or nearly no loss of perfume occurred at higher temperatures.
15 Example 2 Perfume carrier granules of the following composition were prepared: ingredients R1 Bentonite STPP Polyethylene Glycol 4000 1 Perfume 19 The granules were introduced in a detergent-powder to reach a perfume concentration of 0.15% in the final product, i.e. a product with protected perfume. The perfume performance under different conditions as -6shown below was assessed by sniffing against a benchmark, i.e. a standard, containing 0.2% of non protected perfume.
The assessment was carried out by a trained panel of 10 people. The products were evaluated on a 0 to 4 scale, 0 being the worst score and 4 the best.
The following results were obtained: Formulation with after rinse in wash 0.2% of the nonprotected perfume 0.15% of the protected perfume benchmark R1 3 3.25 3 3.25 neat 3 3.40 These results show that the protected perfume had a better performance.
