Patent Application
20100152083
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products.
Consumer products may comprise one or more perfumes and/or perfume delivery systems that can provide a desired scent to such product and/or a situs that is contacted with such a product and/or mask an undesirable odor. While current perfumes and perfume delivery systems provide desirable odors, consumers continue to seek products that have scents that may be longer lasting and that are tailored to their individual desires (see for example USPA 2007/0275866 A1 and U.S. patent application Ser. No. 12/133,866)—unfortunately the pool of perfume raw materials and perfume delivery systems that is available is still too limited, due for example to potential supply constraints, to completely meet the perfume community's needs. Thus, perfumers need an ever larger pool of perfume raw materials and perfume delivery systems that can replace current or serve as alternatives to current perfume materials.
Applicants believe that the perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume community's options, as such perfume raw materials can provide the overall performance, including, for example, character and/or odor profiles, of p-tert.Butyl-alpha-methyldihydrocinnamic aldehyde which is also known as Lilial®.

After mixing at higher speed until a stable emulsion is obtained, the second solution and 4 grams of sodium sulfate salt are added to the emulsion. This second solution contains 10 grams of butyl acrylate-acrylic acid copolymer emulsifier (Colloid C351, 25% solids, pka 4.5-4.7, Kemira), 120 grams of distilled water, sodium hydroxide solution to adjust pH to 4.8, 25 grams of partially methylated methylol melamine resin (Cymel 385, 80% solids, Cytec). This mixture is heated to 70° C. and maintained overnight with continuous stirring to complete the encapsulation process. 23 grams of acetoacetamide (Sigma-Aldrich, Saint Louis, Mo., U.S.A.) is added to the suspension.
