advantageously stable under high vacuum such as the vacuum conditions used for SEM measurements. Advantageously, embodiments of method involve the deposition of a polymer film on a primary capsule such as a silica capsule using polymer particles, particularly polymer latex particles, without a crosslinking chemistry or curing agent or organic solvent. For example, embodiments of the methods disclosed herein do not involve free radical chemistry which limits application potential and do not require a chemical reaction such as polymer grafting or surface functionalization (such as surface initiated ATRP) of a silica capsule. As such, embodiments of the methods disclosed herein do not need any block co polymer (which is more expensive and require synthetically more steps to produce as compared to the polymer latex particles used in embodiments of the method) or controlled radical polymerization. Special silane monomers such as organo alkoxy silanes to render the silica surface hydrophobic are also not required in embodiments of the methods disclosed herein. In this regard, as embodiments of the methods disclosed herein do not use coupling chemistry and are based on physical phenomena, sensitive actives can be encapsulated and applied. Advantageously, embodiments, of the methods disclosed herein are suitable encapsulating a wide variety of active compounds, oils, hydrophobic actives/formulations and also for sensitive actives e.g. actives that react with free radicals. As such, embodiments of the methods disclosed herein are suitable for cosmetic/consumer-based applications such as for perfumes or aromatic oils or other consumer-based product encapsulation. As compared to chemical-based methods, embodiments of the disclosed method rely primarily on water-based technology without the need to use organic solvents. For example, water-based chemistry may be employed for both silica capsule and latex synthesis. Advantageously, the water-dispersed polymer latex used do not require chemical curing but instead rely on physical curing (e.g. by making use of temperature or pH) of a polymer layer on a primary capsule shell
