Encapsulation technology essentially deals with the incorporation of commercially available active material into protective system that can deliver the active to specific site.

Target Delivery


Skin, hair and mucosal surfaces are useful targets for the delivery of active compounds. The core is covered by solid shell which is used to deliver, protect stabilize or control the release of the core/active

Protective Shell

  • Usually selected from a list of materials “generally regarded as safe” (GRAS) to meet the needs of the application as well as regulatory demands e.g.. Biodegradability
  • USP Grade
  • Suitable for personal care use



Ingredients encapsulated include colors, fragrances, flavors, vitamins & oils etc.

Level of Incorporated active

Will depend upon the nature of the active ingredients being encapsulated.

Level of Active

Reasons to employ an encapsulation:

Reasons to employ an encapsulation
  • Superior handling of active material (e.g. conversion of liquid active agent into a powder).
  • Improved stability in fnal products during processing (e.g. less evaporation of volatile active).
  • Creation of visible effects.
  • Adjustable properties of active components (particle size, structure, oil or water soluble color.
  • Off taste masking.
  • Controlled release.

Types of Encapsulated Beads

Pressure release / burst release / water penetration control system.

Pressure release burst release
  • This is design as water as the main agent controlling the release of the active.
  • In this system active molecules cannot physically diffuse out the device without water molecule diffusing in
  • This is usually achieved by incorporating actives in hydrophilic polymer that is stiff when dry but swells when placed in aqueous environment.

pH Responsive Spheres

pH Responsive Spheres
  • In this technique Spheres are coated with ionic pH sensitive polymers having as main feature that they release protons in response to pH change.
  • Having a structure acid or basic groups that can accept or release protons in response to pH change in surrounding environment.

Types of Encapsulated Beads

Color in color Beads

Color Beads
  • These Spheres gives color changing effect on rubbing.
  • Color in color Spheres is a simple concept where in the core is of one color and the out shell can be of different color.
  • The process consists essentially of spraying a color solution fluid on to particles of substrate material undergoing encapsulation.
  • This is achieved by fluid bed coating.

Oil Encapsulation

Oil Encapsulation
  • The encapsulation method provided Spheres where oil droplets were well dispersed and protected.
  • The wall material used commonly includes synthetic polymer and natural biomaterials (usually carbohydrates).

Flavor and Fragrance Encapsulation

  • Encapsulation of flavor and fragrance in dedicated shell.
  • It can limit the degradation or loss of the flavor during the various product process and storage.
  • The shell can also provide the functional properties such as control release of aromatic molecules in given environment.


Film Casting

  • Films are hydrophilic and temperature sensitive in nature.
  • It dissolve upon contact with wet surface such as tongue within few seconds.
  • We can encapsulate oil and color in various attractive shapes.
