Description

EXAMPLE 1

[0086] Table 1 provides a list of non-compacted and compacted perfume compositions. All percentages are given by weight of the total perfume composition. Under Markers is meant the total percentage of Performance Markers A1 in the perfume compositions. Under Vehicles is meant the total percentage of Performance Vehicles A2 in the perfume compositions. Under Diluents is meant the total percentage of Performing Diluents B1 in the perfume compositions. Under Low Odour Ingredients is meant the total percentage of solvents and low odour ingredients having an Odour Value of less than 100 in the perfume. Under # Over critical Markers is meant the total number of Performance Markers A1 being present at a concentration which is equal to or higher than their specific Critical Compaction Concentration. NC means not compacted; TDC means compacted via a top-down creation process; BUC means compacted via a bottom-up creation process according to the present invention.

[0087] In the above table, Perfume B is a compacted version of Perfume A (having a musky woody character) in which the solvents (Low Odour Ingredients) have been replaced mostly by Performing Diluents (top-down creation process). However, the concentration of both Performance Markers and Performance Vehicles is under-critical and the compacted version has lost in bloom intensity.

[0088] Perfume D is a compacted version of Perfume C (having a sweet-woody-chypre character), also obtained through a top-down process. In this case, part of the performing diluents has been replaced by more powerful Performance Vehicles. Nevertheless, the concentration of Performance Markers is still under-critical and the blooming performance of the perfume is not acceptable. Perfume D has only one Performance Marker at over-critical concentrations: Cyclogalbanate (1%).

[0089] Perfume E was a perfume having strong citrus-floral character, characterized by a high level of orange essence, terpenic alcohols, hedione and woody/musky ingredients. This perfume could not be compacted using a top-down creation process without a complete loss of the citrusfloral odour direction.

[0090] Conversely, Perfumes F (a strong citrus-floral perfume) and G (a fruity-floral perfume) have been obtained through a bottom-up creation process, according to the present invention. Perfume F comprised the following Performance Markers A1 at over-critical concentrations: (E)-undec-9-enal (0.1%), Rose oxide (1%) and Spirogalbanone (0.4%), and Perfume G comprised following Performance Markers A1 at over-critical concentrations: Aldehyde C 11 undecylenic (1%), Rose oxide (0.7%) and Violet nirile (0.014%). Perfumes F and G are well balanced perfumes performing extremely from both a performance and hedonic stand points.

[0091] Perfumes H and I are further examples of compacted perfumes obtained by performing a bottom-up creation process in accordance with the invention: Perfume H is a strong fougre spicy oriental compacted perfume comprising following Performance Markers A1 at concentrations equal to or higher than their specific Critical Compaction Concentrations: Ambrocenide (0.05%), Damascenone (0.2%), Delta damascone (2%), Dupical (0.5%), Galbanone (0.5%), Methyl laitone (0.5%) and Shisolia (0.5%). Perfume I is a floral carnation compacted perfume comprising following Performance Markers at over-critical concentrations: Cetone V (1%), Trans-dec-4-enal (0.6%) and Rosyrane Super (0.25%).

EXAMPLE 2

[0092] Performance evaluation. A series of compacted perfume compositions created according to the method and composition rules defined by the present invention were evaluated in use in a hard surface cleaner product.

[0093] The base was a model base comprising 2% by weight of C14-17 secondary alkyl sulfonate (Hostapur SAS 60, ex Clariant), 2% by weight of C13 ethoxylate (Lutensol TO 10, ex BASF), 1% by weight of triethanolamine (ex Prolabo), 0.3% by weight of citric acid (ex Prolabo), 0.2% by weight of sodium hydroxide at 50% in dionized water (ex Prolabo) and 0.1% by weight of a mixture of NN-dihydroxymethyl urea and 1,6-dihydroxy-2,5-dioxo-hexane (Parmetol DF 35, ex Schulke & Mayr).

[0094] The level of compacted perfume composition in the product was 0.18% by weight, whereas the level of a reference un-compacted perfume composition was 0.5% by weight. The performance of the perfume compositions in terms of smell intensity (or perfume strength) was assessed in a monadic in-home use test under domestic application conditions. The quantity of product tested was 500 ml. The product was tested three times within 10 days. The number of panellists was 85. The results are reported in Table 2.

[0095] The compacted perfume K contained the following Performance Markers A1 at concentrations equal to or above their CCC: Tridecenonitrile ((E)-tridec-2-enenitrile, 4.5%), trans-dec-4-enal (0.9%), Cassyrane (0.9%), Galbanone (0.7%), and 3,5,5-trimethylhexanal (0.7%).

[0096] The compacted perfume L comprised Performance Markers A1 at over-critical concentrations equal to or above their CCC: Delta damascone (1.8%), Dupical (0.9%), trans-dec-4-enal (0.9%), Pharaone (0.14%).

EXAMPLE 3

[0097] Two perfumes were tested in both conventional and compacted granulated detergent compositions. Perfume M was a non-compacted green-floral accord comprising terpene alcohols and nitriles, Iso E super, Lilial, Gardenol, Aubepine para cresol, Jasmacyclene, Peonile and Undecavertol, and Perfume N its compacted variant. The characteristics of these two perfumes are reported in Table 3. The two detergent compositions were evaluated in a monadic sequential in home consumer test. The size of the test was 150 panellists. The test conditions and the results on a scale of 7, 7 being the maximal score, are also reported in Table 3.

TABLE-US-00003 TABLE 3 Non Compacted Compacted perfume M perfume N Composition(*) Performance Markers (%) 2.8 4.0 Performance Vehicles (%) 19.2 19.8 Performing Diluents (%) 43.7 40.4 Other fragrance ingredients (%) 34.3 35.8 Low odour ingredients (%) 0 0 # Over-critical Markers(**) 0 5 Detergent Conventional Compacted Detergent dosage in machine wash test (g) 150 30 Perfume dosage in detergent (%) 0.75 0.75 Consumer testing results Overall opinion of the perfume 5.7 6.0 Overall opinion of product efficiency 5.6 5.9 (*)in % by weight of the total perfume composition (**)number of Performance Markers with a concentration equal to or higher than its specific Critical Compaction Concentration, respectively.

[0098] As apparent from the results of Table 3, the compacted perfume N was rated higher by the panellists at a dosage 5 times lower than that of the non compacted perfume M. This example illustrates the importance of having in a compacted perfume at least three Performance Markers being at a level higher than or equal to their Critical Compaction Concentration.

EXAMPLE 4

[0099] A compacted perfume O was created comprising 5.2% by weight of Performance Markers A1, 68.6% by weight of Performance Vehicles A2 (Ethyl Maltol, Nectaryl, Petalia, Undecavertol) and 26.2% by weight of Performing Diluents B1 (Agrumex, Citrus essence, Orange essence). This perfume did not contain any additional perfume ingredient and did not contain any low odour ingredient. The compacted perfume O comprised seven Performance Markers A1 at concentrations equal to or above their CCC: Cassyrane (0.5%), Dupical (1.0%), Galbanone (1.0%), Javanol (1%), Oxane (0.75%), Rose Oxide (0.5%) and Thiogeraniol (0.1%).

EXAMPLE 5

[0100] A compacted perfume P was created comprising 7.8% by weight of Performance Markers A1, 35.30% by weight of Performance Vehicles A2 (Ethyl Maltol, Nectaryl, Petalia, Undecavertol) and 23.75% by weight of Performing Diluents B1 (Agrumex, Citrus essence, Orange essence). The compacted perfume P comprised 14 Performance Markers A1. From these 14 Performance Markers, 9 had concentrations equal to or above their CCC: Aldehyde C12 MOA (0.4%), Bigaryl (0.06%), Damascone Delta (1.6%), Dupical (1.6%), Evernyl (0.8%), Galbanone (0.27.0%), Javanol (0.40%), Pyralone (0.27%), Rose Oxide (1.2%) and Violet nitrile (0.016%).
