Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detergents, and relates to a mildew-proof and odor-removing fresh laundry detergent. BACKGROUND

[0002] After clothes are washed and dried, bad odor is generated, which is mainly caused by medium-chain aldehydes, medium-carbon-chain alcohols, ketones, sulfur-containing compounds, nitrogen-containing compounds, short-chain fatty acids and the like.

[0106]

[0107] As can be seen from the data in Table 2, the fragrance releasing and lingering effects of Examples 1-3 are better than those of Comparative Examples 3-5, wherein the fragrance releasing and lingering effects of Comparative Example 3 are the worst, the fragrance releasing effect of Comparative Example 4 is good but the lingering effect is poor, and the lingering effect of Comparative Example 5 is good but the fragrance releasing effect is slightly poor.

The addition of isopropyl myristate and ethanol in the core of the fragrance microcapsule makes the perfume better dispersed and dissolved, and the isopropyl myristate forms a thin film on the surface of the clothes to keep the fragrance persistent.
