Abstract
A composition may be or include detergents, cleaning agents, and cosmetic agents and include an emulsifier and biodegradable microcapsules. The biodegradable microcapsules may include a core material and a shell where the shell consists of at least one barrier layer and a stability layer. The barrier layer may surround the core material. The stability layer may include at least one biopolymer and be arranged on the outer surface of the barrier layer(s).
Claims19
A composition comprising:
- biodegradable microcapsules wherein:
- each biodegradable microcapsule comprises a core material and a shell,
- the shell comprises at least one barrier layer and a stability layer,
- the at least one barrier layer surrounds the core material,
- the stability layer comprises at least one biopolymer and is arranged on an outer surface of the at least one barrier layer, and
- an emulsion stabilizer is optionally arranged at the transition from the at least one barrier layer to the stability layer;
- and
- at least one emulsifier, wherein:
- the at least one emulsifier is selected from the group of ethoxylated, hydrogenated castor oils having mean ethoxylation (EO) values ranging from 30 to 50, and
- the at least one emulsifier is present in an amount ranging from 0.001 wt. % to 0.08 wt. %, based on the total weight of the composition,
- wherein the composition is a detergent, a cleaning agent, a cosmetic agent, or any combination thereof.
A composition comprising:
- biodegradable microcapsules wherein:
- each biodegradable microcapsule comprises a core material and a shell,
- the shell comprises at least one barrier layer and a stability layer,
- the at least one barrier layer surrounds the core material,
- the stability layer comprises at least one biopolymer and is arranged on an outer surface of the at least one barrier layer, and
- an emulsion stabilizer is optionally arranged at the transition from the at least one barrier layer to the stability layer;
- and
- at least one emulsifier, wherein:
- the at least one emulsifier is selected from the group of ethoxylated, hydrogenated castor oils, and
- the at least one emulsifier is optionally present in an amount ranging from 0.001 wt. % to 0.25 wt. %, based on the total weight of the composition,
- wherein the core material of the biodegradable microcapsules comprises at least one perfume composition, and wherein the at least one perfume composition, based on the total weight of all odorants within the at least one perfume composition, comprises:
- 10 wt. % or less of odorants having a CLogP of 2.5 or less and a boiling point of 200° C. or more,
- 15 wt. % or less of at least one odorant having a CLogP of 4.0 or less and a boiling point of 275° C. or less, and
- 30 wt. % or less of at least one odorant having a vapor pressure of 5 Pa or less at 20° C., and
- wherein the composition is a detergent, a cleaning agent, a cosmetic agent, or any combination thereof.
