Description

) PERFUMED COLOURED SPECKLE COMPOSITION AND PARTICULATE
LAUNDRY DETERGENT COMPOSITIONS CONTAINING IT
TECHNICAL FIELD
The present invention relates to coloured perfumed speckles for use in granular laundry detergent compositions and a process for making them.
BACKGROUND AND PRIOR ART
Commercial laundry detergent washing powders often contain ingredients which do not provide any cleaning function but provide an additional benefit to the consumer. One such commonly used ingredient is perfume. Perfume is added to improve aesthetic appeal by imparting a pleasing odour both during storage and in use. Additionally it may impart a pleasing odour to the washed fabrics. By their very nature perfumes are highly volatile and the amount remaining on the washed clothes by the end of the washing process is usually a small fraction of that which was added at the beginning.
There have been many attempts to improve and control the release of perfume during the wash process.
WO 9734981 (Procter & Gamble) discloses a porous zeolite into which the perfume is absorbed and trapped by a release . inhibitor which hydrolyses during the wash thereby releasing the perfume in a controlled manner.
particle encapsulated in a glassy material and coated in a k water-soluble or dispersible compound. Preferably a perfume is supported or contained within the porous carrier.
EP 466235 (Quest) discloses a process of combining a perfume with one or more non-ionic emulsifiers to form a non-aqueous phase which is then mixed with an aqueous phase to form a structured emulsion containing liquid-crystal structures.
The emulsified perfume is added to a detergent powder and is said to enhance perfume delivery and possibly deposition.
Another ingredient which is commonly added and yet provides little or no washing function is visually striking ‘speckles’. Their primary function is to provide an attractive colouration to the powder and a cue to prompt the consumer into associating the speckles with a separate functional effect.
US 5 605 883 (Iliff et al) discloses a colourant speckle which exhibits reduced spotting of teated fabrics. It also states that the speckle may be used as a vehicle for carrying cosurfactants, enzymes, oxidants, bleach activators and fragrances.
US 4 097 418 (Procter & Gamble) discloses a granular coloured speckle having reduced staining properties and may . comprise up to 3% of enzymes, bleaching agents, antimicrobial agents, corrosion inhibitors and perfume.
) SUMMARY OF INVENTION ~
Surprisingly the present inventors have discovered that the delivery of perfume may be significantly enhanced and prolonged if the perfume is included in coloured speckles.
Especially advantageous perfume delivery can be achieved if the perfume is incorporated in the speckles in aqueous emulsion form. Additionally the colouration of the speckles may provide an association with the enhanced perfume delivery in the mind of the consumer, thus reinforcing the consumer's appreciation of the wash process.
STATEMENT OF INVENTION
In a first aspect, the present invention provides a perfumed coloured granular composition for use as speckles in a particulate laundry detergent composition which comprises at least 1 wt% perfume.
In a second aspect, the present invention provides a process for the manufacture of a perfumed coloured granular composition for use as speckles in a particulate laundry detergent composition, comprising the steps of: (i) mixing an aqueous perfume emulsion and a colourant with an inorganic granular carrier material; and ' (ii) layering the resultant material with a finely divided porous particulate material.
In a third aspect, the present invention provides a perfumed particulate laundry detergent composition comprising a minor
) proportion of a coloured speckle composition wherein at least 10 wt% of the total amount of perfume in the detergent
LL) composition is located in the speckles.
DETAILED DESCRIPTION OF THE INVENTION
The Speckles
The speckles (perfumed coloured granular composition) comprise a perfume, preferably in aqueous emulsion form, and a colourant, on an inorganic granular carrier material. The speckles comprise at least 1 wt% perfume and preferably comprise at least 1.5 wt%.
It is preferred that, before drying, the perfume is present in the form of an aqueous emulsion. In this case the speckles suitably comprise emulsifier. It is preferred that the speckles are obtainable from a process as defined in detail below.
The Perfume
As used herein the term "perfume" denotes one or a mixture of perfume components, optionally mixed with a suitable solvent, diluent or carrier, which is used to impart a desired odour to the particulate laundry detergent composition in the package and/or in use and/or to the . fabrics that are washed.
A range of perfumes and solvents which may be used are disclosed in EP 466 235 B (Quest).
) The Aqueous Emulsion ) The perfume is preferably incorporated in the speckles as an aqueous emulsion. Such emulsions suitably contain from 1 to 50 wt% of perfume, from 1 to 30 wt% of one or more non-ionic emulsifiers and from 20 to 98 wt% of water or an aqueous mixture containing water-soluble and/or water-dispersible materials, hereinafter jointly referred to as "aqueous phase". Such water-soluble or water-dispersible materials may form up to 30 wt¥%¥ of the aqueous phase.
It is particularly suitable that the weight ratio of total emulsifier to perfume lies within the range of from 1:5 to 3:1 and the weight ratio of non-aqueous phase to aqueous phase lies within the range of from 1:2 to 4:3, preferably within the range of from 1:2 to 1:1.
Non-ionic emulsifiers suitable for use in the present invention are exemplified in EP 466 235 B, for example the primary and secondary alcohol ethoxylates, especially the
Cg-Cpo aliphatic alcohols ethoxylated with an average of from 1 to 20 moles of ethylene oxide per mole of alcohol, and more especially the Cj10-Ci15 primary and secondary aliphatic alcohols ethoxylated with an average of from 1 to 10 moles of ethylene oxide per mole of alcohol, preferably from 4 to 9. Non-ethoxylated nonionic surfactants include alkylpoly- ) glycosides, glycerol moncethers, and polyhydroxyamides (glucamide) .
- [) -
An especially preferred nonionic emulsifier is C30-Cis, preferably Ci12-Cis, aliphatic alcohol ethoxylated with an average of from 4 to 9 moles of ethylene oxide, preferably 5 to 7, per mole of alcohol.
The emulsion may be produced by forming a non-aqueous phase comprising the perfume, a non-ionic emulsifier or mixture based on non-ionic emulsifiers, and optionally other adjuncts, which is mixed at a temperature at which the non- aqueous phase forms a homogeneous liquid; forming an aqueous phase consisting of water or an aqueous solution of water- soluble or water-dispersible materials; and finally mixing the two phases under shear conditions.
The Process
The perfumed coloured granular composition for use as speckles in a particulate laundry detergent composition according to the present invention may be manufactured by the following process: (i) mixing an aqueous perfume emulsion and a colourant with an inorganic granular carrier material; and (ii) layering the resultant material with a finely divided porous particulate material.
The colourant may be a pigment or a water-dispersible dye.
Optionally the inorganic carrier material may be layered prior to step (i) with a finely divided porous particulate
