Disclosed are clear, aqueous perfume compositions which are free of ethanol. There is further provided a perfume composition which is clear, provides a good skin feeling, and good air drying properties on the skin.

Aqueous oil in water micro-emulsions, and product

The invention relates to the use of polymeric particles for boosting the UV absorption of an UV filter in an UV-sunscreen composition, wherein the polymeric particles comprise at least one polymeric particle comprising at least one chromophore having an UV absorption maximum at &#x3bb;&#x2267;275 nm covalently bound thereto.

Additive for UV-sunscreen preparations

Aminoplast microcapsules comprising a core of fragrance and a shell of aminoplast polymer, the composition of the shell being from 75-100% of a thermoset resin comprising 50-90% of a terpolymer and from 10-50% of a polymeric stabilizer; the terpolymer comprising: The capsules are competitive with known aminoplast capsules and have the major advantage that they are formaldehyde-free.

Aminoplast microcapsules containing fragrance

Microcapsules comprising a core of fragrance and a shell of aminoplast polymer, the composition of the shell being from 75-100% of a thermoset resin comprising 50-90%, preferably from 60-85%, of a terpolymer and from 10-50%, preferably from 10-25%, of a polymeric stabilizer; the terpolymer comprising: (a) from 20-60%, preferably 30-50% of moieties derived from at least one polyamine, (b) from 3-50%, preferably 5-25% of moieties derived from at least one aromatic polyol; and (c) from 20-70%, preferably 40-60% of alkylene or alkylenoxy moieties having 1 to 6 methylene units, preferably 1 to 4 methylene units and most preferably 1 methylene unit; the microcapsules additionally optionally comprising up to 25%, preferably up to 10% of a cationic polymer. The microcapsules are useful for the storage and dissemination of fragrance in various products, such as laundry products and fabric care products.

Microcapsules

The polymeric nanoparticles including olfactive components have a glass temperature of &#x3e;50&#xb0; C. They are obtainable by continuously adding a monomer component and an olfactive component to an aqueous solution. The aqueous solution comprises a first initiator and an emulsifier. The added components are distributed in the aqueous solution to obtain reaction mixture while the polymerization of the monomer component is started at the first temperature. The liquid monomer component and the olfactive component are added continuously while a second initiator is added dropwise to the reaction mixture and the first temperature is maintained. After terminating the addition of liquid monomer component and the olfactive component the temperature of the reaction mixture is increased to a second temperature and a third initiator is added dropwise.
