Abstract
Washing and cleaning agents may include microcapsules comprising a core material where the core material may include at least one fragrance and a shell. The shell may consist of at least one first layer and one second layer with different chemical compositions. The shell may have a biodegradability, measured in accordance with OECD 301 F, of at least 40%. Such agents may be used for conditioning textiles or for cleaning textiles and/or hard surfaces.
Claims19
A washing or cleaning agent comprising:
- microcapsules each comprising a core and a shell, wherein:
- the core comprises a core material,
- the core material comprises a fragrance,
- the shell comprises a first layer and a second layer having a chemical composition different from a chemical composition of the first layer,
- the shell has a biodegradability, measured in accordance with OECD 301 F, of at least 40%,
- the second layer comprises an aldehyde component, an amine component, and an aromatic alcohol selected from the group consisting of resorcinol, phloroglucinol, and aminophenol,
- the aldehyde component is present in an amount of from 5.0 to 50 wt. %, based on the total weight of the second layer,
- the amine component is present in an amount of from 20 to 85 wt. %, based on the total weight of the second layer, and
- the aromatic alcohol is present in an amount of from 5.0 to 15 wt. %, based on the total weight of the second layer;
- and
