摘要:
The present invention provides compositions and clear oil-in-water microemulsion containing up to 80% w/w of an oil, a surfactant system, a w/w oil/surfactant system ratio between 1 and 3, and a solubilizing-aid ingredient which is not a surfactant neither a VOC compound, the latter being present in an amount sufficient to ensure that the ratio oil/(surfactant+solubilizing-aid) is between 0.1 and 5. The present invention concerns also the articles and products associated with such compositions and microemulsions, and the methods to manufacture them.

摘要:
The invention relates to a spray-dried composition comprising an active ingredient dispersed in a carrier comprising a combination of a wall-forming carbohydrate material with from 1 to 30% by weight of agar agar relative to the dried weight of the composition. The composition of the invention provides advantageous behavior in an aqueous environment wherein the mobility of the active agent is restricted in the gelled carrier, thus preventing the release of the agent unless shear of heat are applied. Another feature of the invention is a process for the preparation the spray-dried composition.

摘要:
The present invention relates to air freshener devices that have water-based liquid compositions, preferably clear liquids, for providing an improved rate of emanation of perfume ingredients from the air freshener emanating surface and allowing the use of fragrance materials with a wide range of characteristics, namely a wide range of clogP values. The air fresheners contain liquid perfume compositions which include: i) 0.5 to 40% w/w of a perfume; ii) an oil-solubilizing system containing one or more surfactants of the non-ionic, anionic, cationic, amphoteric type, or a mixture thereof; iii) a solubilizing-aid; and iv) at least 40% weight of water; with the weight percentages being relative to the total weight of liquid composition.

The present invention relates to air freshener devices of water-based liquid compositions, preferably clear liquids, that provide an improved diffusion of the composition and allow the use of fragrance materials with a wide range of characteristics, namely a wide range of clogP values. The compositions are clear microemulsions particularly adapted for use in automatic air fresheners and comprise at least 40% w/w of an aqueous phase, preferably water, an active oil in an amount of between 0.01 and 5% w/w, an oil-solubilizing system which is formed of a surfactant mixture of ionic and non-ionic surfactants, a solubilizing-aid ingredient in an amount of up to 5% w/w, and a propellant system in an amount of up to 40% w/w, wherein the perfume oil to total surfactant mixture is present at a weight ratio of between 0.2 and 4.5.
