Abstract
The present invention primarily relates to a method for producing a powder containing a plurality of capsules incorporated into crystals, wherein these capsules contain one or more ingredients. Further, the present invention relates to the respective powder, as well as product containing this powder, the use of the powder as well as methods for producing respective products and methods for perfuming substrates.
Claims13
A method for producing a powder, wherein the powder comprises capsules (K) enclosed in crystals and the capsules (K) include one or more ingredients, the method comprising:
- (i) providing one or more solvents, one or more crystallisable materials, and capsules (K) containing the one or more ingredients,
- (ii) optionally, increasing the temperature of the one or more solvents,
- (iii) adding (iii.1) the one or more crystallisable materials and (iii.2) optionally, the capsules (K) before, after, or simultaneously with the crystallisable materials, to the one or more solvents and dissolving the one or more crystallisable materials in the one or more solvents to obtain a mixture (M1),
- (iv) reducing the temperature of the mixture (M1) to a temperature below or even with the crystallization temperature of the one or more crystallisable materials,
- (v) adding the capsules (K) or, respectively, further capsules (K), wherein (v) is optional in case (iii.2) is applied,
- (vi) further reducing the temperature of the mixture (M1) to obtain a mixture (M2) comprising capsules (K) enclosed in crystals and containing one or more ingredients, wherein the mixture (M2) is cooled to a temperature resulting in the precipitation of the capsules (K) enclosed in crystals and containing the one or more ingredients, without spray drying;
- and
- (vii) collecting the precipitated crystals to obtain the powder of capsules (K) enclosed in crystals containing the one or more ingredients, and not a liquid capsule dispersion.
