Disclosed are stable microcapsule compositions each containing a microcapsule dispersed in an aqueous phase and a stabilizing agent. The microcapsule compositions are stable for at least 4 weeks when storing at 45° C., and the microcapsule composition is considered stable when (i) the composition has a viscosity of 3000 cP or less and (ii) 20% or less water by volume of the composition is separated from the composition. Also disclosed are consumer products having such a stable microcapsule composition.

An improved delivery particle comprising a benefit agent core material and a shell encapsulating the core material is described, along with a process for forming such a delivery particle and articles of manufacture. The shell is the reaction product of: i) an isocyanate or acid chloride or acrylate with ii) an amine-containing natural material having free amino moieties, and iii) an a, β -unsaturated compound, the a, β -unsaturated compound forming C-N covalent bonds with the amine moieties of the natural material. The delivery particle of the invention has improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.

Oil-based particles have an average particle size of 0.05 mm to 10 mm, and include: (A) polar oil; and (B) an oily gelling agent having a melting point of 60° C. or more.

Compositions and methods are disclosed for repairing split ends in hair and/or micro-damage to hair shafts. The compositions comprise a variety of oils, optionally including meadowfoam seed oil (Limnanthes alba seed oil), abyssinian oil (Crambe abyssinica seed oil), and camellia seed oil (Camellia oleifera seed oil). The compositions for repair of split ends and/or micro-damage to hair shafts may be encapsulated in microcapsules. The disclosed compositions and methods can completely repair split ends 3 mm long and under, within one-minute following application.

The present invention provides starch film-forming compositions and methods of their use for preparing capsule shells. The starch film-forming composition includes a gellan gum and at least one starch, wherein the total acyl content of the gellan gum ranges from 14 to 34%. The starch film-forming composition of the present invention has the advantages of desired film-forming strength and toughness, which can be applied in soft capsules to obtain soft capsules with a desired adhesive property upon formation and encapsulation property and which is free of animal-derived ingredients. The soft capsules thus are suitable for all ethnic populations in the world and can be applied globally.

Described herein is a delivery system including a carrier and a perfume formulation, where the perfume formulation includes 0 to 60 wt. % of a hydrophobic solvent, 40 to 100 wt. % of a perfume oil, where the perfume oil has at least two of the following characteristics: at least 35% of perfuming ingredients having a log P above 3, at least 20% of Bulky materials of Groups 1 to 6 and at least 15% of high impact perfume materials having a Log T<−4, where the perfume formulation is entrapped in the carrier. Also described herein are perfuming compositions and perfumed consumer products including the delivery system.

The present invention is directed to a method for producing advantageous microcapsules. Moreover, the present invention provides microcapsules obtained/obtainable by the method according to the invention.
