The present invention relates to a whistle and mouthpiece for a whistle and method of manufacturing that provides a flavored composition in the whistle mouthpiece material that the wearer can taste to make the use of the whistle more bearable over the course of its long use. A flavorant is infused within the thermoplastic material, which is dissolved to release flavor and allow the user to enjoy for a prolonged period of time. The method of manufacturing involves infusing flavorant within the thermoplastic material of the whistle mouthpiece.

Sustainable thermoplastic carbohydrate-based polymeric materials, and sustainable plastic materials including an organic odor-reducing agent to counteract a slight burned carbohydrate odor resulting from inclusion of a carbohydrate-based polymeric material within the described materials. Such carbohydrate-based polymeric material may be starch-based, and the slight characteristic odor lent by such material may be that of a somewhat burned starch, such as a popcorn or caramel corn type odor. Applicant has found that this slight odor can be substantially removed by addition of a very small fraction of particular organic materials. 4-hydroxy-3-methoxybenzaldehyde (vanillin) has been found to be particularly effective, even in very small concentrations. Other freeze-dried fruit extracts (e.g., strawberry, raspberry, blueberry, etc.) may similarly be used. As little as 20 ppm of the organic odor-reducing agent is sufficient to substantially remove the characteristic burned starch odor. A ratio of the odor-reducing agent to the carbohydrate-based polymer may be less than 1:1000.

A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C.sub.9-C.sub.15 aliphatics, C.sub.9-C.sub.15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.

The present invention relates to a composition comprising a polymeric elastomeric phase and an odoriferous active compound. In particular the present invention relates to a composition comprising a polymeric elastomeric phase in form of an acrylic block copolymer and an odoriferous active compound, methods of absorption of odoriferous active compound and releasing said odoriferous active compound over a given period of time. The present invention concerns also objects or articles comprising a polymeric elastomeric phase in form of an acrylic block copolymer and an odoriferous active compound, methods of absorption of odoriferous active compound by said objects and articles and releasing said odoriferous active compound over a given period of time.

Perfume microcapsule-containing films, related solutions, and containers including the films (e.g. detergent packets) are disclosed, together with their methods of preparation and use.

The present invention relates to a fragrant material containing aromatic essential oil for improving the retention of the smell and intensity of aroma of aromatic essential oil, and to a method for preparing the same. The fragrant material having long-lasting fragrance according to an embodiment of the present invention contains aromatic essential oil and porous silica loading the aromatic essential oil and having controlled hydrophilicity or hydrophobicity of a surface thereof, wherein the required hydrophilic-lipophilic balance (rHLB) of the aromatic essential oil and the O/C ratio in the porous silica satisfy 0.9required hydrophilic-lipophilic balance (rHLB) of aromatic essential oil/(O/C ratio of porous silica)2.9.

A coated rubber composition includes a rubber composition coated with a liquid refresh agent selected from the group consisting of one or more liquid terpenes, limonene, carvone, pinene, pine needle oil, citral, orange oil, C9-C15 aliphatics, C9-C15 cycloaliphatics, ethyl lactate, dipentene, 1,8-cineole, eucalyptol, citronellol, geraniol, citronellene, terpinen-4-ol, and combinations thereof. A method of application and a coated rubber composition are also disclosed.

An aqueous dispersion, an aqueous coating composition comprising the aqueous dispersion, and coatings made therefrom capable of slow release of fragrance.

Provided an agent for suppressing an odor of a polysulfide compound. This agent for suppressing an odor of a polysulfide compound comprises, as an active ingredient, at least one selected from the group consisting, butyl 2-methylbutanoate, -terpinene, dipentene, cis-4-heptenal, 1,4-cineol, trimethylhexyl aldehyde, and (+)-limonene oxide, wherein the polysulfide compound is represented by the following formula (I): R.sup.1[S].sub.nR.sup.2 (I) (in the formula, R.sup.1 and R.sup.2 are the same or different, and each denote a linear-chain or branched-chain alkyl or alkenyl group having 1 to 6 carbon atoms, and n denotes an integer of 2 to 5).

A plant fiber-containing composite resin molded article contains a base resin, plant fibers, and, a dispersant, in which each of the plant fibers contains an aroma component, the base resin is a crystalline resin, and in a case where a total content of the base resin, the plant fibers, and the dispersant is 100% by mass, a content of the plant fibers is more than or equal to 50% by mass and less than or equal to 90% by mass.
