Definitions

• a fragrance composition is defined as a mixture of fragrance ingredients, if desired mixed with or dissolved in a suitable solvent or solvents and/or mixed with a solid substrate.
• perfume and fragrance are used synonymously.
• Perfume or fragrance ingredients are well known to those skilled in the art, and include those mentioned, for example, in S. Arctander, Perfume and Flavor Chemicals (Montclair, NJ. , 1969), in S. Arctander, Perfume and Flavor Materials of Natural Origin (Elizabeth, N.J., 1960) and in "Flavor and Fragrance Materials - 1991", Allured Publishing Co. Wheaton, III. USA.
• Perfume ingredients may include natural products such as extracts, essential oils, absolutes, resinoids, resins, concretes etc., and also synthetic basic substances such as hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, esters, acetals, ketals, nitriles, etc., including saturated and unsaturated compounds, aliphatic, alicyclic and heterocyclic compounds.
• the present invention relates to fragrance compositions that enhance positive tactile perceptions of surfaces treated with such compositions.
• the invention also concerns the use of fragrance compositions to enhance the positive tactile perceptions of the texture or feel and/or reduces the negative tactile perceptions of consumer products containing the inventive compositions, such as shampoos or skin creams, hard surface cleaners and laundry products.
• the functional qualities of products are considered to be determined by perceptions associated with a limited combination of the five human senses.
• a fabric may look clean after using a laundry powder, an underarm may smell fresh after using a deodorant, and skin may feel soft after using a moisturising cream.
• the separate senses of vision, smell and touch are associated in these cases with perceived qualities.
• research carried out in the USA suggests that the smell of toiletry products is more important to the consumer than the actual function of the product (J. Byme-Quinn, Perfume, people, perceptions and products, in S. Van Toller & G. Dodd (Eds.), Perfumery: The Psychology and Biology of fragrance (pp.205-216).
• tactile perception may be modified by odour through (i) an associative effect caused by repeat exposure to odour/tactile combinations; (ii) pleasant odours making the perception of texture more agreeable (e.g. softer), or (iii) the presence of a pleasant odour inducing a general change in mood that is reflected in response to, for example, rating scores for softness.
• the present invention relates to fragrance compositions that influence or enhance the senses of touch. Furthermore, the current invention involves the use of fragrance compositions that enhance the perception of a range of touch attributes to maximise the functional properties of consumer products.
• the present invention is directed to a method for enhancing the perception of tactile characteristics through the olefactive perception of a fragrance composition delivered either through use of a fragranced product or by direct inhalation.
• the method involves delivering an effective amount of a fragrance composition, preferably one with positive hedonics, to cause an individual's perception of tactile sensations to be statistically significantly different to that obtained in the presence of prior art fragrance that is not designed according to the present invention to obtain multi-sensory effects.
• a fragrance composition is defined as a mixture of fragrance ingredients, if desired mixed with or dissolved in a suitable solvent or solvents and/or mixed with a solid substrate, which can stimulate olfactory and/or trigeminal chemoreceptors in the nasal cavity and cause a physiological or psychological response.
• perfume and fragrance are used synonymously.
• Preferred fragrance compositions are those that bring about a hedonically positive response, where a hedonically positive fragrance composition is one having a scent to which an individual has a pleasant or positive reaction, also termed a positive hedonic response.
• fragrance compositions are described that influence the perception of various different attributes using a sense other than olfaction. By influencing, for example, perception of attributes such as manageability, smoothness, softness, silkiness, sleekness, conditioning, dryness, coarseness, tangled, sliminess, stickiness, or brittleness, fragrance compositions arising from this invention provide a broad sensual appeal and permit consumers to better appreciate products and materials.
• a perfume composition comprises: a) from about 10% by weight in toto of at least two ingredients selected from group A and b) from around 22% by weight in toto of at least five ingredients selected from group B, wherein i.
• Group A consists of:
• Non-odourous or very low odour means that in scores less than 80 on an odour index scale as set out in EP0404470 (based on comparison with the odour intensity of a control sample of a 10% solution of benzyl acetate in dipropylene glycol, which corresponds to an index of 100), and includes diethylphthelate, dipropylene glycol, triacetin, benzyl benzoate, triethyl citrate, Herculyn D (trade mark), isopropyl myristrate and acetyl tributylcitrate.
• Another aspect of the invention relates to a method of delivering enhanced tactile perception of products containing fragrances formulated according to the invention.
• a further aspect of the invention relates to a method of delivering enhanced tactile perception of surfaces treated with consumer products comprising fragrances formulated according to the invention.
• the effect of the fragrance composition on the perception of a normosmic person who finds the fragrance composition to be hedonically positive provides a beneficial change in the perceived touch perception of consumer products containing fragrances formulated according to the invention and of the fabric/hair/skin/hard surface treated therewith.
• a fragranced product comprising a fragrance composition formulated according to the invention significantly alters the perception of a person using the fragranced product, of smoothness and/or softness and/or other tactile attributes.
• the inhalation of a hedonically positive fragrance composition could significantly alter the perception of a person such that perceived tactile properties are enhanced or suppressed in comparison with a product containing a fragrance that is not created according to the invention.
• the fragrance composition is provided as a formulated blend of the essential odorants to cause the desired effect, and optionally contains additional ingredients at appropriate concentrations for hedonic properties.
• the fragrance composition can be administered as a constituent of a fully formulated consumer product (such as a shampoo) or in combination with carriers, preferably low odour or odourless carriers such as mineral oil or water, and additives such as preservatives and the like.
• the fragrance composition provides a hedonically positive response by the inhaling individual.
• Tactile perception-altering fragrance ingredients for use in compositions and methods according to the invention are selected from the forthcoming list which includes includes, where appropriate, trade names and suppliers of the materials of the invention, as well as common or trivial names used in the perfume industry. Descriptions of these materials may be found in standard perfume industry texts such as S. Arctander, Perfume and Flavor Chemicals (Montclair, NJ. , 1969), in S.

• the present invention is based on extensive consumer testing of fragrances and statistical analysis of the resulting data to classify the materials into different categories, namely those that are active in altering the perceptions of tactile attributes and those that are inactive (Z).
• the active materials were further split into a group of particularly active materials, referred to as Group A, and materials with a lesser activity, group B.
• Fragrance compositions can be readily screened and assessed for positive hedonics and effectiveness in altering the perception of tactile attributes. For example, a fragrance composition can be administered to an individual who is questioned as to a positive or negative reaction to the pleasantness of the scent. The fragrance composition can then be administered to the individual for inhalation, or for them to use according to the normal procedure for using the selected product to assess its effectiveness in modifying their perception of tactile attributes.
• a method of screening a fragrance composition for effectively altering perception of tactile attributes can comprise the steps of: administering a supra-threshold and non-irritant concentration of a composition consisting essentially of one or more fragrance compositions to an individual for inhalation; having the individual rate a list of textural attributes (such as smoothness, softness, manageability) of, for example, fabric or hair; comparing the estimate of the tactile properties to actual properties (i.e. without fragrance present) to provide a "difference value"; and then determine the statistical significance of the difference value; and eliminating the fragrance composition as being ineffective for altering perception of fabric, hair or skin softness if not statistically significant.
• textural attributes such as smoothness, softness, manageability
• a second example of a method of screening a fragrance composition for effectively altering perception of tactile attributes can comprise the steps of: providing a consumer product (such as a shampoo) containing a supra-threshold and non-irritant concentration of a composition consisting essentially of one or more fragrance compositions to an individual for use in the normal way (according to standard pack instructions for use of such a product); having the individual rate a list of textural attributes (such as smoothness, softness, manageability) of, for example, fabric or hair, during use of the product; comparing the estimate of the tactile properties to actual properties (i.e.
• the fragrance composition may be dispensed to an individual in a form that can be used for a specific function (e.g. washing hair, or fabric, or applying to skin), that provides a vaporous emission for inhalation, or it may be applied to a surface, such as fabric or hair, in a number of forms including, for example, as a liquid, powder, gel, cream, paste, and the like.
• the fragrance composition can be administered in combination with low odour carrier such as mineral oil or water and/or low odour additives, and can be formulated with a viscosity effective to allow for aerosolization.
• the fragrance composition can be dispensed onto surfaces, for example, by direct application, or by an aerosol or non-aerosol spray, among other modes of application.
• the fragrance composition may be incorporated into a consumer product (such as shampoo, hair conditioner, fabric washing powder or liquid or skin cream) and used according to standard pack instructions in order to deposit fragrance onto the surface treated (e.g. during washing hair, or fabric or applying skin cream).
• fragrance composition in a real use situation can be confirmed by including the fragrance in a fully formulated product and asking a sample of the consumer population to use the product and report on its touch and feel characteristics during use and the touch or feel characteristics of their hair, skin or fabric during and after use.
• the fragrance should be included in the product at a level that is normal for the type of product being tested (e.g. 0.5% in shampoo base), and respondents should be instructed to use the product as they would normally use the product to under normal in-use conditions.
• the composition comprises a hedonically positive fragrance composition in a supra- threshold and non-irritant concentration effective to alter perception of tactile attributes upon inhalation such that the tactile properties are perceived as being significantly different than the actual tactile properties.
• This experiment was designed to define the fragrance characteristics that modify the perceptions of the touch and feel of a shampoo product before use and during use and the feel of the hair during use of the product and after use.
• Identical shampoo bases were prepared and each was perfumed with different fragrances.
• the shampoos were tested for their physical properties (viscosity and foaming) to confirm that the fragrances had not modified the physical parameters.
• the respondents completed a questionnaire assessing the perceived touch or feel of the product and of the hair during use.
• the respondents' attention was not drawn to the fragrance of the products.
• the products were assessed for (i) feel on the hands before it is applied to the hair; (ii) feel on the hands and hair whilst applying it, including the lather; (iii) how the hair felt after using the product, but whilst the hair was still wet; and (iv) how the hair felt after drying but before using any styling products.
