Abstract

The invention discloses sweet osmanthus sustained-release essence, which is prepared from the following components in parts by weight: 9.60 to 14.40 parts of hydroxypropyl-beta-cyclodextrin, 2.50 to 4.80 parts of sweet osmanthus essence, 0.40 to 0.64 part of xanthan gum, 0.12 to 0.30 part of sodium alginate, 0.02 to 0.08 part of Tween 80, 0.10 to 0.20 part of calcium chloride, and 79.58 to 86.44 parts of deionized water. The invention further provides a preparation method of the sweet osmanthus sustained-release essence. According to the preparation method, the hydroxypropyl-beta-cyclodextrin and sodium alginate are adopted as a double-layer wall material for wrapping the sweet osmanthus essence, the load rate of which is 15.67 percent to 30.62 percent, and the wrapping effect is good. The sweet osmanthus sustained-release essence is applied to perfuming cotton fabrics, after being placed for 20 days, a strong sweet osmanthus fragrance is stilled kept, and the fragrance is coordinative and soothing.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a sustained-release essence, in particular to an osmanthus sustained-release essence and a preparation method thereof. Background technique [0002] As we all know, fragrance is a mixture of organic volatile compounds such as various esters, alcohols and phenols. Fragrances are usually directly added to detergents, and during the washing of textiles, fragrances are easily affected by the external environment such as light, heat, oxygen, etc., or react with surfactants and bleaches in the formula, resulting in the decomposition of fragrances or The aroma changes. And in the washing process, the essence is released instantaneously, and the fragrance persistence of the fabric after washing is poor, and the essence used in the existing detergents cannot achieve the effect of sustained release. At the same time, the essence microcapsule technology continues to develop in the process of...
