The outer layer may be substantially uniform in thickness. The outer layer may comprise about 10%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 2 1%, about 22%, about 23%, about 24%, about 25% or about 30% of the hybrid/composite capsule. In various embodiments, the outer layer is physically deposited on the inner layer. In various embodiments, the hybrid/composite shell does not comprise a polyelectrolyte such as a poly(allylamine hydrochloride) (PAH). Accordingly, the hybrid/composite shell may be substantially inert e.g. does not react with an encapsulated active. The hybrid/composite capsule may be substantially spherical in shape. The hybrid/composite capsule may be micron- or submicron-sized. In various embodiments, the hybrid/composite capsule has a size/diameter/particle size/particle size distribution/average particle size in the range of from about 100 nm to about 100 pm, from about 500 nm to about 100 pm, from about 1 pm to about 100 pm, 10 pm to about 100 pm, from about 20 pm to about 100 pm, from about 30 pm to about 100 pm, from about 40 pm to about 100 pm, from about 50 pm to about 100 pm, from about 60 pm to about 100 pm, from about 70 pm to about 100 pm, no less than about 70 pm, no less than about 60 pm, no less than about 50 pm or no less than about 40 pm. In various embodiments, the hybrid/composite capsule comprises one or more actives loaded in a core of the capsule that is encapsulated by the shell of the primary capsule. For example, the hybrid/composite capsule may be loaded with one or more cargoes selected from the following: oil, silicone oil, active including sensitive active (e.g. sensitive to free radical reactions), aroma, aroma oil, flavour, fragrance, perfume, drug, therapeutic, cosmetic, skin care substance, consumer care substance, combinations or mixtures or derivatives thereof. In various embodiments, the hybrid/composite shell is substantially inert e.g. does not react with an encapsulated active.
