Patent Application
20220016004
The present disclosure relates to the field of perfumery. In particular, the present disclosure provides a deodorant or an antiperspirant composition comprising perfume raw materials defined by Log P and used according specific proportions. A dispensing device comprising the composition is also an object of the present invention.
One of the problems faced by the perfumery industry lies in the relatively rapid loss of the olfactive benefit provided by odoriferous compounds due to their volatility. The perfume industry has a particular interest for compositions or additives which are capable of prolonging or enhancing the perfuming effect of a mixture of several fragrances at the same time over a certain period of time. It is particularly desirable to obtain long-lasting properties for standard perfumery raw materials which are too volatile or have a poor substantivity by themselves, or which are only deposited in a small amount onto the surface of the final application.
Furthermore, fragrances play an important role in the perception of products performance and thus they often determine the consumer's choice for a given product. In detergents, hard surface cleaners or personal- or body-care products, the fragrances are incorporated as a free oil and/or encapsulated in microcapsules in order to deliver a pleasant odor to the skin or to the fabrics.
It would be interesting to have an antiperspirant or deodorant composition providing a dual effect with a change of olfactive character over time while showing a boost of freshness upon application.
The present disclosure provides a solution with an antiperspirant or deodorant composition comprising perfume raw materials defined by Log P and used according specific proportions.
A first object of the invention is therefore an antiperspirant or deodorant composition comprising:
characterized in that the perfume raw materials comprise:
A second object of the invention is a perfume composition comprising perfume raw materials; wherein the perfume raw materials comprise:
A third object of the invention is the use of a composition as defined above to modify the olfactive character of said composition under wet conditions.
A fourth object of the invention is a method for modifying the olfactive character of a composition comprising the steps consisting of:
The present invention provides an antiperspirant or a deodorant composition comprising a perfume composition including a first group of perfuming compounds formed of raw materials and a second group of perfuming compounds formed of raw materials respectively defined by their Log P values.
The Applicant shows that the olfactive character of the perfume composition as defined in the present invention changes under wet conditions.
Indeed, the use of a perfume composition comprising a specific combination of raw materials defined according to their physico-chemical properties enables to create distinct smells within a single fragrance when said composition is subjected to wet conditions.
In other words, two different fragrance directions can be perceived by a consumer from a single fragrance during the transition from dry stage to wet stage. For example, when sweating, the consumer will perceive a change in freshness and strength perception.
A first object of the invention is therefore an antiperspirant or deodorant composition comprising:
As used herein, the term “perfume raw materials”, refers to a compound or mixture of perfuming ingredients, which are used in a perfuming preparation or composition to impart a hedonic effect. In other words such perfuming ingredients, to be considered as being a perfuming one, must be recognized by a person skilled in the art as being able to impart or modify in a positive or pleasant way the odour of a composition, and not just as having an odour.
As used herein, the term “perfuming ingredient” it is meant a compound, which is used for the primary purpose of conferring or modulating an odour. In other words such an ingredient, to be considered as being a perfuming one, must be recognized by a person skilled in the art as being able to at least impart or modify in a positive or pleasant way the odour of a composition, and not just as having an odour. For the purpose of the present disclosure, perfume accord also includes combination of perfuming ingredients with substances which together improve, enhance or modify the delivery of the perfuming ingredients, such as perfume precursors, emulsions or dispersions, as well as combinations which impart an additional benefit beyond that of modifying or imparting an odour, such as long-lasting, blooming, malodour counteraction, antimicrobial effect, microbial stability, insect control.
The nature and type of the perfuming ingredients do not warrant a more detailed description here, which in any case would not be exhaustive, the skilled person being able to select them on the basis of its general knowledge and according to intended use or application and the desired organoleptic effect. In general terms, these perfuming ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulphurous heterocyclic compounds and essential oils, and said perfuming co-ingredients can be of natural or synthetic origin. Many of these ingredients are in any case listed in reference texts such as the book by S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, N.J., USA, or its more recent versions, or in other works of a similar nature, as well as in the abundant patent literature in the field of perfumery. It is also understood that said ingredients may also be compounds known to release in a controlled manner various types of perfuming compounds.
According to the invention, the perfume composition can comprise in addition to perfume raw materials, at least one solvent to dissolve said perfume raw materials, which is of current use in the perfumery industry. The solvent is preferably chosen in the group consisting of dipropylene glycol (4-oxa-2,6-heptanediol+2-methyl-3-oxa-1,5-hexanediol+2,4-dimethyl-3-oxa-1,5-pentanediol), Isopar M (hydrocarbons C13-C14), Isopar L (hydrocarbons C11-C13), isopropyl myristate (isopropyl tetradecanoate) ethyle citrate (triethyl 2-hydroxy-1,2,3-propanetricarboxylate), triacetine (1,2,3-propanetriyl triacetate), benzyl benzoate, 1,3-propanediol, mixture of methyl dihydroabietate and methyl tetrahydroabietate, vegetable oils such as almond oil, argan oil, cotton oil, corn oil, olive oil, sunflower oil, castor oil and mixtures thereof.
In other words, it means that solvents are not included in the perfume raw materials as defined in the present invention.
According to the invention, the perfume raw materials comprise:
According to an embodiment, the sum of perfume raw materials of group A and perfume raw materials of group B is comprised between 35% and 80% by weight based on the total weight of the perfume raw materials.
The skilled person will be able to select the raw materials from the first group and raw materials of the second group according to their Log P value on the basis of his general knowledge. Log P is the common logarithm of estimated octanol-water partition coefficient, which is known as a measure of lipophilicity.
The Log P values of many perfuming compound have been reported, for example, in the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, Calif., which also contains citations to the original literature. Log P values are most conveniently calculated by the “C LOG P” program, also available from Daylight CIS. This program also lists experimental log P values when they are available in the Pomona92 database. The “calculated log P” (c Log P) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each perfume oil ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The c Log P values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental Log P values in the selection of perfuming compounds which are useful in the present invention.
Thus, by adjusting a correct balance between raw materials having a low Log P and raw materials having a high Log P, a “2 in 1” fragrance is obtained where two different olfactive directions are provided under wet conditions in conjunction with an increase in intensity (boost).
According to an embodiment, the first group of perfuming compounds is formed of perfume raw material having a Log P≤2.5 and the second group of perfuming compounds is made of perfume raw materials having a Log P≥4.5.
According to another embodiment, the perfume raw materials comprise between 2-25% by weight of the first group A of perfume raw materials and between 2-25% by weight of the second group B of perfume raw materials.
According to a particular embodiment, the sum of perfume raw materials of group A and perfume raw materials of group B having an odor detection threshold (ODT)≤2×10−3 μg/L is greater than 8%, preferably between 8 and 80%, more preferably between 15 and 80% based on the total weight of the perfume raw materials.
According to the invention, the term “Odour Detection Threshold” refers to the lowest vapour concentration of that material which can be olfactorily detected.
The odor threshold concentration of a perfuming compound is determined by using a gas chromatograph (“GC”). Specifically, the gas chromatograph is calibrated to determine the exact volume of the perfume oil ingredient injected by the syringe, the precise split ratio, and the hydrocarbon response using a hydrocarbon standard of known concentration and chain-length distribution. The air flow rate is accurately measured and, assuming the duration of a human inhalation to last 12 seconds, the sampled volume is calculated. Since the precise concentration at the detector at any point in time is known, the mass per volume inhaled is known and hence the concentration of the perfuming compound. To determine the threshold concentration, solutions are delivered to the sniff port at the back-calculated concentration. A panelist sniffs the GC effluent and identifies the retention time when odor is noticed. The average across all panelists determines the odor threshold concentration of the perfuming compound. The determination of odor threshold is described in more detail in C. Vuilleumier et al., Multidimensional Visualization of Physical and Perceptual Data Leading to a Creative Approach in Fragrance Development, Perfume & Flavorist, Vol. 33, September, 2008, pages 54-61.
According to a particular embodiment, the perfume composition further comprises at least 10% by weight of perfume raw materials of group C having a log P comprised between 2.5 and 4 (2.5 and 4 excluded) and/or an ODT with an odor detection threshold (ODT) of 2×10−3 μg/L.
As non-limiting examples of perfume raw materials with log P≤2.5 and ODT≤2×10−3 ug/L air, one may cite compounds listed in table A below.
As non-limiting examples of perfume raw materials with log P≥4 and ODT≤2×10−3 ug/L air, one may cite perfume raw materials of table B.
