Description

The painted spot composition of fragrance and comprise the particulate laundry detergent composition of said composition
Technical field
The present invention relates to the spot of employed painted fragrance in the granular laundry detergent compositions, and the method for making them.
Background technology
The washing powder of commercial detergent for washing clothes often comprises the component that any cleaning function is not provided but the human consumer is provided added advantage.A kind of normally used like this component is a perfume compound.The perfume compound that adds is by storing and giving the magnetism that the pleasant fragrance of washing composition improves its aesthetic property between the usage period.In addition, it can give a kind of pleasant fragrance of fabric of having washed.Because their special characteristic, perfume compound is highly volatile, and in finishing to washing process, the amount that remains in the perfume compound on washing clothes is generally the sub-fraction that the initial stage adds.
The trial of the release of perfume compound in existing many improvement and the control washing process.
WO 9734981 (Procter ﹠amp; Gamble) disclose a kind of porous zeolite, perfume compound is absorbed and be trapped in the porous zeolite by release inhibitor, the hydrolysis in washing of this inhibitor, thereby can discharge perfume compound with a kind of controlled way.
WO 9842818 (Procter ﹠amp; Gamble) disclose and a kind ofly be encapsulated in the glassy material and be coated with the porous core particle that applies water-soluble or water-dispersible compound.The preferred fragrance agent is loaded on or is included in this porous support.
EP 466235 (Quest) discloses perfume compound has been mixed with one or more nonionic emulsifier to form nonaqueous phase, then with its method that comprises the structured lotions of liquid crystal structure with formation mixed with water.With this emulsive perfume compound add detergent powder to, allegedly can improve the release of perfume compound and possible deposition like this.
Another kind of add usually but provide the component that washing function seldom or is not provided be visually significantly ' spot '.Their main effect is attractive color is provided and furnishes a hint for impelling the human consumer that this spot and other effect are interrelated for powder.
US 5605883 (Iliff etc.) discloses a kind of tinting material spot, its showed the processed fabric that reduces spot.It also sets forth this spot can be as the carrier that carries cosurfactant, enzyme, oxygenant, bleach-activating agent and spices.
US 4097418 (Procter ﹠amp; Gamble) disclose the painted spot of a kind of granulous, it has the tinctorial property that has reduced, and can comprise enzyme, SYNTHETIC OPTICAL WHITNER, antiseptic-germicide, inhibiter and perfume compound up to 3%.
Summary of the invention
The inventor is surprisingly found out that, if perfume compound is inclusive in the painted spot, can strengthen and prolong the release of perfume compound significantly.If the perfume compound of water miscible liquid form is mixed in the spot, can realize that particularly advantageous perfume compound discharges.In addition, the painted of this spot can be in a kind of association that the perfume compound that improves is discharged of providing of human consumer, thereby strengthens the evaluation of human consumer to this washing process.
Invention is set forth
In first aspect, the invention provides a kind of painted granular composition that is used as the fragrance of spot in the particulate laundry detergent composition, it comprises the perfume compound of at least 1 weight %.
In second aspect, the invention provides a kind of manufacture method that is used as the painted granular composition of the fragrance of spot in the particulate laundry detergent composition, it may further comprise the steps:
(i) mix perfume compound water miscible liquid and tinting material and granular inorganic carrier material; With
