Analytical methods that can be employed to reliably separate known or suspected allergens in a complex mixture of fragrance ingredients are described.

Disclosed here is a composition containing menthol and menthyl lactate, and its preparation method and its applications as a cooling agent and a flavoring agent.The present invention provides a composition characterized in that it comprises menthol and menthyl lactate in a ratio by weight in the range of 1:4˜4:1 and the corresponding crystallization point is below room temperature of 25° C. Such composition has the advantages of being liquid at room temperature; easy to use as a cooling agent or a flavoring agent; no need to use heat to melt menthol and menthyl lactate, which not only saves time, money and heating equipment, but also simplifies manufacturing process and can be used in cold processes at room temperature. The composition can be used as a cooling and / or flavoring agent and / or a fragrance ingredient in toothpaste, mouthwash, fragrance, cleansers, shaving cream, after shave products; shampoo, deodorant, antiperspirant, bath products, drinks, confectionary products, tobacco, pharmaceutical, foods, flavoring and fragrance products.

The invention belongs to the field of extraction of plant essential oil and in particular discloses a method for extracting peony essence from fresh peony flowers. The method comprises the following steps: performing supercritical CO2 extraction on the fresh peony flowers as raw materials to prepare peony extract, and extracting the peony extract to obtain the peony essence by employing a molecular distillation method. According to the method, since the fresh peony petals are taken as the raw materials, the spice components, thermal-sensitive substances and other active ingredients in the peony petals are maintained to the greatest extent, desensitization treatment is performed in the extraction process of essential oil, the condition that some people have pollen allergy is avoided; since the peony essential oil is extracted through the supercritical CO2 extraction method, the phenomenon that the thermal-sensitive substances in the peony flowers are lost because of heating in the traditional method is avoided; and meanwhile, the residue problem of the harmful substances caused by extraction by employing an organic solvent and the treatment and recovery problems of the organic solvent are solved, the environmental pollution is reduced, and the energy consumption is reduced.

Household cleaning, fabric treatment, or deodorizing products and methods of preserving the integrity of hydrophilic perfume ingredients and extending fragrance life are disclosed. The product and method include an aqueous composition containing a surfactant and a perfume having a substantial proportion of hydrophilic perfume ingredients with a Clog P of less than about 3 and a boiling point greater than about 200° C. The aqueous composition may be contained in plastic containers constructed of hydrophilic perfume compatible materials. The invention preserves perfume integrity by decreasing migration of hydrophilic perfume ingredients into and / or transmission through plastic containers and extends fragrance life once the hydrophilic perfume ingredients are deposited onto a surface.

A fibrous structure with a plurality of fibrous elements and agglomerated particles. The agglomerated particles can be matrix particles containing perfume.

Perfume compositions comprise between 10% and 30% in total by weight of perfume ingredients selected from two groups, Group A, Group B, with the provisos that over 5% but less than 15% of the perfume composition must comprise Group A ingredients, and for compositions comprising less than 10% of Group A ingredients the agregate percentage of Group B ingredients present must be at least equal to the expression 2* / 10-A%) where A% is the total percentage of Group A ingredients in the composition.
