Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a high bulk density granular detergent composition which can be widely used as a detergent composition for clothes.

2. Description of the Related Art At present, various fragrances are blended in granular detergents that are generally used for the purpose of adjusting the scent of the detergent when it is used and after washing it to make it comfortable. But,
These fragrances have a problem that their effects are gradually lost under the influence of oxidation and the like as they age in a detergent. It has been found that this tendency of deterioration of the perfume is particularly remarkable when the detergent composition contains a nonionic surfactant. However, in the high bulk density granular detergents that are the mainstream of the present granular detergents, the nonionic surfactant is an essential component from the viewpoint of improving the powder physical properties and maintaining the solubility. For this reason, there has been a demand for a granular detergent composition having good fragrance stability due to a fragrance, even if a nonionic surfactant is blended.

[0002]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a high bulk density granular detergent composition having good fragrance stability due to a fragrance even after a long period of time.

DISCLOSURE OF THE INVENTION The present invention is based on the finding that the fragrance due to a fragrance can be stably maintained for a long period of time by incorporating a certain amount of sulfite into a detergent, and the above-mentioned problems can be solved. Was done. That is, the present invention contains 3.1 to 10% by weight of sulfite, 1 to 30% by weight of nonionic surfactant, and 0.01% by weight or more of fragrance,
A bulky granular detergent composition having a bulk density of 0.6 g / ml or more is provided.
