Description

PACKAGED HOMECARE PRODUCT

Field of the Invention

The present application is in the field of packaged homecare products comprising perfumes.

Background of the Invention

Homecare products typically comprise fragrances. The fragrances signal efficacy to a consumer and are therefore an important part of the consumer product experience.

However, perfume or fragrance compositions are very sensitive to other ingredients in a composition and to the external environment. Instability is identified by consumers through various mechanisms, most commonly a change in fragrance, a change in product colour or a change in the quantity of fragrance in the headspace above a product. One particularly sensitive group of fragrance ingredients are esters and those with a vapor pressure greater than 1 Pa at °C.

There is an ongoing need for suitable packing to improve fragrance stability in homecare products.

Summary of the Invention

It has been found that packaging comprising a bag and a container provides improved stability for homecare compositions comprising particular perfume compositions.

Accordingly in one aspect of the present invention is provided a product comprising packaging and a homecare composition; wherein the homecare composition comprises 0.1 to 30 wt.% perfume by weight of the homecare composition, wherein the perfume composition comprises an ester and I or at least 25 wt.% materials having a vapor pressure of >1 Pa at 20°C, by weight of the perfume composition; and wherein the packaging comprises a bag and a container, the bag housed within the container. The invention further relates to a method of packaging a homecare composition, wherein a homecare composition comprising 0.1 to 30 wt.% perfume is packaged in a bag, contained in a container, wherein the perfume comprises an ester and I or at least 25 wt.% materials having a vapor pressure of >1 Pa at 20°C, by weight of the perfume composition.

In a further aspect of the present invention is provided a use of packaging comprising a bag and a container, to package a homecare composition comprising 0.1 to 30 wt.% perfume, wherein the perfume comprises an ester and I or at least 25 wt.% materials having a vapor pressure of >1 Pa at 20°C, by weight of the perfume composition.

Preferably the level of an enzyme is from 0.1 to 200, more preferably from 0.5 to 150, even more preferably 1 to 120, most preferably from 5 to 110 mg active enzyme protein per 100g homecare composition.

A preferred class of enzymes are nucleases. A nuclease enzyme is an enzyme capable of cleaving the phosphodiester bonds between the nucleotide sub-units of nucleic acids and is preferably a deoxyribonuclease or ribonuclease enzyme. Preferably the nuclease enzyme is a deoxyribonuclease, preferably selected from any of the classes E.C. 3.1.21.x, where x=l, 2, 3, 4, 5, 6, 7, 8 or 9, E.C. 3.1.22.y where y=l, 2, 4 or 5, E.C. 3.1.30.Z where z= 1 or 2, E.C. 3.1.31.1 and mixtures thereof. A preferred class of enzymes are proteases. Protease enzymes hydrolyse bonds within peptides and proteins, in the laundry context this leads to enhanced removal of protein or peptide containing stains. Examples of suitable proteases families include aspartic proteases; cysteine proteases; glutamic proteases; aspargine peptide lyase; serine proteases and threonine proteases. Such protease families are described in the MEROPS peptidase database (http://merops.sanger.ac.uk/). Serine proteases are preferred. Serine proteases are a subgroup of proteases characterized by having a serine in the active site, which forms a covalent adduct with the substrate. Subtilase type serine proteases are more preferred. The term "subtilases" refers to a sub-group of serine protease according to Siezen et al., Protein Engng. 4 (1991) 719-737 and Siezen et al. Protein Science 6 (1997) 501 -523. Most preferably the protease is a subtilisins (EC 3.4.21.62).

A preferred class of enzymes are amylases. Suitable amylases (alpha and/or beta) include those of bacterial or fungal origin. Chemically modified or protein engineered mutants are included. Amylases include, for example, alpha-amylases obtained from Bacillus, e.g., a special strain of B. licheniformis, described in more detail in GB 1,296,839, or the Bacillus sp. strains disclosed in WO 95/026397 or WO00/060060.

A preferred class of enzymes are cellulases. Suitable cellulases include those of bacterial or fungal origin. Chemically modified or protein engineered mutants are included. Preferred cellulases are selected from the genera Bacillus, Pseudomonas, Humicola, Fusarium, Thielavia, Acremonium, e.g., the fungal cellulases produced from Humicola insolens, Thielavia terrestris, Myceliophthora thermophila, Fusarium oxysporum and combinations thereof such as those disclosed in US 4,435,307, US 5,648,263, US 5,691 ,178, US 5,776,757, WO 89/09259, WO 96/029397, and WO 98/012307.

A preferred class of enzymes are lipases. Lipases are lipid esterase enzymes, and the terms lipid esterase and lipase are used herein synonymously. Cleaning lipid esterases are discussed in Enzymes in Detergency edited by Jan H. Van Ee, Onno Misset and Erik J. Baas (1997 Marcel Dekker, New York). Preferably the lipid esterase may be selected from lipase enzymes in E.C. class 3.1 or 3.2 or a combination thereof. More preferably the lipid esterases is selected from: Triacylglycerol lipases (E.C. 3.1.1.3), Carboxylic ester hydrolase (E.C. 3.1.1.1), Cutinase (E.C. 3.1.1.74), Sterol esterase (E.C. 3.1.1.13), Wax-ester hydrolase (E.C. 3.1.1.50).

Preservatives including bacteriacides pH buffers, hydrotropes, antifoams, polyelectrolytes, solvents, anti-corrosion agents, anti-oxidants, chelating agents, hydroxamates

Shading or hying dyes, flourescers and optoical brigthteners Composition asthetic agents such a pearlisers, opacifiers, colourants and dyes

- Additional benefit agents such as insect repellents and sunscreens Rheology modifiers, such as polymers (e.g. hydrophobically modified alkali swellable emulsion (HASE) copolymers, cationic polymers), crystallisable glycerides or cellulose fibres.

The product described herein is intended to be used to dispense a homecare formulation. The packaging may be used to pour a laundry product into a washing machine drawer or alternatively into a dosing ball. Alternatively the packaging may comprise a composition to clean surfaces, in which case, the composition may be dispensed directly onto a surface, a cleaning material (e.g. a sponge or a cloth) or may be dispensed into a spray bottle. The composition may be a washing up liquid or an automatic dishwasher liquid, in which case the composition may be dispensed directly into a washing up vessel or a dishwasher. The homecare compstion may be a so called ‘concentrated’ composition, in which case the composition may be dispensed into a secondary container in which it is mixed with water to produce a composition suitable for use. Such compositions may be referred to as ‘dilute at home’ compositions, meaning that the consumer dilutes the ‘concentrated’ formulation with water to produce a composition suitable for use. This reduces the amount of packaging required and the weight of product purchased by the consumer. Description of the figures

Figure 1 depicts packaging comprising a container (1) in the shape of a cuboid, and a dispensing means in the form of a spout (3). The container (1) contains a bag (2) (not visible). The spout (3) is connected to a bag (2) (not visible) via a base portion (4). The spout (3) protrudes through the container wall via an opening in the container wall. Perforations (5) depict a flap which when depressed, aids the consumer in accessing the dispensing means. A handle is provided (6) which is a cut out portion of the container wall. Figure 2 depicts the packaging of figure 1 priror to the removal of any perforated sections (5). The perforated sections may be removed by the consumer to provide a handle and a hole through which the spout can protrude.
