- the present invention also relates to a method of reducing or masking a malodour on a substrate.
- the compositions of the invention are applied to the substrate in an amount sufficient to give a malodour reducing or masking effect .
- compositions may be applied to the chosen substrate by any suitable method, e.g. by spraying directly onto the substrate, by applying a foam or mousse by dabbing/padding etc onto the substrate. Spraying onto the substrate is the preferred method.
- the substrate may be any substrate as above which has a malodour which it is desired to remove.
- Preferred substrates are fabric- containing substrates or items . Examples of such substrates include clothing items, upholstered items and soft furnishings (e.g. curtains), tableware, animal bedding and soft toys. Clothing includes shoes, coats, jackets etc.
- the compositions of the invention are not intended to be applied directly to the human body or to an animal body.
- the types of malodours that may be treated with the compositions of the invention include any undesirable odour e.g. tobacco odours, smoke, cooking odours, animal originating odours, body odours and musty smells.
- the compositions of the invention may be packaged in any suitable dispenser, e.g. a pump or spray dispenser. Especially preferred are hand-operated spray units which can be used to spray the composition directly on to the substrate.
- each mixture is stirred for a period of 72 hours .
- each mixture is sprayed onto cloth odorised with stale tobacco aroma .
- composition (ii) had the stale tobacco aroma completely removed and/or covered and the cloth had a pleasant, floral aroma.
- Formulation A and formulation B were then stirred for a period of 72 hours. At the end of the 72 hours, each of formulations A and B were placed into 100ml pump dispensers.
- the tea towels sprayed with formulation A had an aroma intensity scaled at 10 on a scale of 1-10 as assessed by a 30-member panel .
- the tea towels sprayed with formulation B had a value of 5 for intensity as assessed by the 30-member panel.
- the tea towels sprayed with formulation A had a pleasant aroma which lasted for a period of 144 hours at the same level as assessed by the 30-member panel.
- the tea towels sprayed with formulation B, after 144 hours had an aroma scaled at 1 by the 30-member panel.
- the acetal-containing formulation A is far superior for both substantivity and strength to the non-reacted component in formulation B.
- Example 3 solvent and surfactant containing examples
- compositions containing partially hydrolysed PVA were prepared by pre-mixing the perfume and Eumulgin L and then adding the preservative and water.
- Example 4A is a comparative composition (which is still according to the invention) but which does not contain PVA. All percentages are by weight .
- compositions were sprayed onto cotton fabric pieces (30cm x 20cm) at a dosage of between 0.9-1.0 gram per square.
- the fragrance intensity was measured by assessors who smelt the treated cotton pieces after 5 and 7 days.
- Each assessor smelt the treated cotton pieces and made a comparison of example 4A with 4.1, and separately, 4A with 4.2. After 5 and 7 days the fabrics were sprayed with water at a dosage of between 0.9-1.0 grams on each piece to determine if there was any change in fragrance intensity.
- composition (5.1) comprising 0.20%wt of a perfume mixture comprising perfume of Example l.ii, water, preservative and a nonionic surfactant was prepared.
- composition (5.2) comprising 0.20wt% of the same perfume but where the pre-reaction of the aldehyde/ketone with the Carbinol had not occurred was also prepared.
- the two samples were placed into separate 100ml dispensers and lOg of one of the samples was sprayed evenly onto a cotton tea- towel which had previously been washed in an unfragranced detergent powder.
- the other sample was similarly sprayed onto such a tea-towel.
- the sprayed tea-towels were left for 72 hours in identical storage conditions and then assessed for perfume intensity by 10 panellists who assessed which was the most intensely perfumed tea towel .
- the table below shows the % of panellists assessing each tea towel as the most intensely perfumed.
- compositions in the table below having a single surfactant as the solubilising aid (B) , were prepared by mixing the perfume with the surfactant, followed by addition of the preservative and then the demineralised water. The compositions were then stored at 0 C and 37 C for two weeks to assess the physical stability of the products. All % are in % by weight based on the total amount of the composition.
- the perfume used comprised the perfume mixture of Example l.ii above.
- EMPIGEN® EMPIGEN® OC/E, Alkyl dimethylamine oxide (ex Albright
- EMAL® EMAL® 270D/EG, Sodium Alkyl Ether Sulphate 2 EO (ex
- REWOQUAT® REWOQUAT® CPEM, Coconut alkyl (bis hydroxyethyl) methyl ethoxylated methosulphate (ex Goldsmith) .
- Examples 6.1 to 6.9 were physically stable at the end of the two week storage tests.
- Examples 6.10 to 6.14 became cloudy and showed physical separation within a day of preparation, or did not produce a homogenous composition initially. However, after shaking, the compositions could still be used to provide the desired treatment of malodours .
- compositions in the table below, having a mixture of surfactants as the solubilising aid (B) were prepared following the method of example 6 but using said mixture.
- the storage of the compositions, the percentages and the perfume used are all as for Example 6.
- Examples 7.1 to 7.3 were physically stable at the end of the two week storage tests.

- compositions in the table below having a mixture of surfactant and a water miscible solvent as the solubilising aid (B) , were prepared following the method of example 6 but with the solvent and surfactant added before the perfume was added.
- the storage of the compositions, the percentages and the perfume used are all as for Example 6.
- Examples 8.1 and 8.2 were physically stable at the end of the two week storage tests.
- Examples 8.3 and 8.4 became cloudy and showed physical separation within a day of preparation, or did not produce a homogenous composition initially. However, after shaking, the compositions could still be used to provide the desired treatment of malodours,
- compositions in the table below, having a water miscible solvent as the solubilising aid (B) were prepared following the method of example 6 but with the solvent used instead of the surfactant.
- the storage of the compositions, the percentages and the perfume used are all as for Example 6.
- Examples 9.1 to 9.4 were physically stable at the end of the two week storage tests.
