The present invention relates to a fragrance composition, to a method for obtaining a fragrance composition, to a fragrance composition obtainable by such a method and to a use of such a fragrance composition.
One sought after benefit of perfumed products is the generation of a nice odor that increases the comfort of the user and an olfactive cue related to the product efficacy. In hand dish washing, this traditionally translates into the generation of a powerful blooming odor on contacting the dish wash product with water or wet dishes and cooking utensils and during foam formation. Such a blooming odor has the additional advantage of counteracting malodors that often emanate from the cooking utensils. Today consumers are however increasingly keen to experience additional benefits with perfumed products. The capability of consumer products to generate odors that fill the room where a product is applied is becoming a key performance indicator conditioning product repurchasing. Room filling should enhance the action of the perfumed product beyond the sink and reinforce the perception of cleanness and hygiene in the whole kitchen.
WO 2017/209708 A1 discloses a non-irritant hand dishwashing composition. This composition does not comprise any perfume.
EP 2 391 699 B1 discloses a method employing a liquid hand dishwashing detergent composition comprising a humectant and a cationic polymer. The composition optionally comprises a perfume.
U.S. Pat. No. 8,343,906 B2 discloses an alkaline hand dishwashing product containing a hydrogen peroxide bleach and bleach stable perfume composition.
WO 2002/064722 A2 discloses automatic dishwashing compositions comprising diacyl peroxide bleach and blooming perfume.
US 2007/0099804 A1 discloses a method of formulating perfume composition which are designed for use in wash-off system to provide either a desired initial release with minimal residual perfume on the targeted system, a long sustained release of fragrance.
These documents do not provide dishwashing products providing perfume release with both blooming and room filling performances.
Creating such dual effects in a balanced way is difficult. Commercial products typically provide either a strong bloom on the cost of room filling or a strong room filling on the cost of bloom. On the other hand, attempts to provide an optimal balance between bloom and room filling typically result in depressing both effects.
It is therefore a problem underlying the present invention to provide diffusive fragrance compositions for hand wash products that offer both enhanced bloom and enhanced room filling, and are hedonically pleasant to the consumer all over the time the product is applied and perceived.
This problem is solved by the subject-matter of the independent claims. In a first aspect, the present invention provides a fragrance composition comprising, preferably consisting of:
When added to a consumer product, especially a hand dishwashing liquid, fragrance compositions fulfilling the aforementioned rules show enhanced bloom intensity and room filling intensity, as well as optimal balance between these two effects.
In the context of the present invention, the bloom intensity is assessed during foam formation, after having added a known amount of tap water to the consumer product, and at a distance of from 0.5 to 2 meters from the sink.
The room filling intensity is assessed a certain time, for example between 15 and 30 minutes, after foam formation, at a distance of from 0.5 to 2 meters from the sink.
Preferably both bloom intensity and room filling intensity are assessed according to the standardized procedures described in Example 3.
The term “volatility” refers to the equilibrium headspace concentration (HS), expressed in microgram/liter (μg/l). This is the concentration of an ingredient in the gas phase in equilibrium with the condensed form—that is solid or liquid form—of said ingredient at a temperature of 25° C. and at a pressure of 1 atmosphere (normal pressure). It can be measured by using any of the known quantitative headspace analysis techniques in the art. A suitable method is described, e.g., in Mueller and Lamparsky in Perfumes: Art, Science and Technology, Chapter 6 “The Measurement of Odors” at pages 176-179 (Elsevier 1991).
The equilibrium headspace concentration may be measured as follows: 500 mg of a test perfumery ingredient are added to a container which is then sealed. The container is incubated at constant 25° C. until the compound reaches equilibrium between the gas and the condensed phase. A defined volume of headspace (usually 0.5-1.0 liter) is trapped on a micro filter using poly(4-ethylstyrene-co-divinylbenzene) porous material, for example Porapak Q from Supelco, as sorbent. After extraction with an appropriate solvent (usually 30-100 microliters methyl tertiary butyl ether), an aliquot of the extract is analyzed by GC. The concentration in the original headspace can be calculated (in terms of μg/l) from the headspace volume sucked through the micro filter and the aliquot of the filtered extract injected into the gas chromatograph. The final headspace concentration value of the tested perfumery ingredient is obtained as the mean value of three independent measurements each. Further information on the technique hereinabove described may be found in the article of Etzweiler, F.; Senn E. and Neuner-Jehle N., Ber. Bunsen-Ges. Phys. Chem. 1984, 88, 578-583.
The term “odor detection threshold” (ODT) used herein above refers to the average concentration above which a perfume ingredient can be perceived by a panelist and can be measured by olfactometry, as described, for example in Mueller and Lamparsky in Perfumes: Art, Science and Technology, Chapter 6 “The Measurement of Odors” at pages 176-179 (Elsevier 1991).
The odor detection threshold (ODT) may be measured by using an olfactometer. The olfactometer functions on the principle of a linear dilution of an odorant in a carrier gas. The quantity of odorant displaced depends on its vapor pressure and the carrier gas flow. A constant flow of nitrogen, regulated by a flow regulator, carries the odorant from a sample container to a mixing chamber. There, the carrier gas-odor mixture is diluted with odorless air. From the mixing chamber one part of the diluted odorous air is allowed to flow via a fused silica capillary to the sniffing funnel. The flow rate through the capillary, which determines the dosage of odorous air from the mixing chamber into the sniffing funnel, depends on the opening the valve which can be regulated via PC from 1 to 256 ml in binary steps. The final dilution of the odorous air sample occurs in the glass funnel by flushing them permanently with odorless air at a flow rate of 8 L/min. Forced-choice triangle presentation is achieved by a special automated channel setting device where only one position of a switch the odorant delivering capillary enters in the sniffing funnel, whereas in two other positions the capillary is positioned outside the funnel and where the effluent is sucked away. After each trial the channel setting is changed automatically and in a random order. The concentration is calculated from the odorants vapor pressure and from the dilution ratios that were applied in the olfactometer, assuming that vapor pressure saturation is achieved in the sample generator. As a control the concentration is determined analytically by sampling a known volume from the capillary effluent into a headspace filter and by subsequent gas chromatographic quantitation of the odorant in the desorption solution.
Each panelist (panel of 15 persons) starts sniffing at the olfactometer at a concentration level at which he perceives the odorant at medium intensity. After three correct answers in three consecutive trials (or four correct answers of five trials) at the same level, stimulus concentration is decreased by a factor of two to the next lower level, and so on, until the panelist has reached his threshold level. The final threshold value of a given odorant is obtained as the mean value of all individual threshold levels.

Fragrance 3.1 has been modified in order to fulfill the conditions defined by the present invention, while still keeping the overall olfactive character of the perfume (Table 10).
The following fragrance has been taken from US 2007/0099804 A1, Table 6, which corresponds to a fragrance for a rinse-off product having optimized release of the fragrance hedonic profile with time in the presence of water. The names of the original ingredients listed in Table 11 were replaced by current synonyms. The solvents dipropylene glycol and isopropyl myristate have been omitted in the percentage calculation in this Table, as only the percentages based on the total of (non-solvent) fragrance ingredients count in claim 1 of the present invention.
Fragrance 3.3 comprises more than 10% by weight of Group A ingredients, less than 20% of Group B ingredients, less than 60% of Group C ingredients and less than 6% by weight of Group C1 ingredients.
Fragrance 3.3 has been modified in order to fulfill the conditions defined by the present invention, while still keeping the overall olfactive character of the perfume.
Each of the fragrance compositions disclosed in Examples 1 to 3 was incorporated into a hand dish wash product base at a level of 0.2 wt.-%. The perfumed base was let to macerate for at least 24 hours before using the product. An internal standard hand dish wash base formulation was used.
The olfactive evaluation was performed in 5 m3 cabins equipped with a sink and an evaluation window located at about 1 m apart from the sink and at an elevation of about 0.7 m with respect to the level of the sink. Both blooming and room filling performance were assessed by a panel of 8 to 9 experts who rated the odor intensity on a scale of 1-5 (1=barely noticeable, 2=weak, 3=medium, 4=strong and 5=very strong).
The bloom performance was assessed in the cabin with both door and window closed. The ventilation was stopped. 1 liter of water at 35° C. was poured into the sink. 5 ml of product were applied onto the abrasive surface (about 0.05×0.05 m2) of a wash sponge and the sponge was squeezed three times to let the product penetrate into it. Then, the sponge was placed into the water, squeezed again three times to produce foam, and the blooming performance was assessed during foaming. The panelists were standing in the cabin and sniffing the air at a distance of about 0.6 m above the sink for 1 minute.
2 liters of tap water at a temperature of 20° C. were then added to the sink, the panelists left the cabin and the door of the cabin was closed. The room filling performance was assessed through the evaluation window after 30 minutes.
The results are reported in Table 13.
As apparent from the results in Table 5, the fragrance compositions obeying the composition rules according to the present invention perform better in term of bloom and room filling intensities, while keeping constant odor intensity between both stages.
