Technology

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

Core

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

Target Delivery

Level of Incorporated active

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

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.
• 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 Beads.

• In this technique beads 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.

Color in color Beads.

• These beads gives color changing effect on rubbing.
• Color in color beads 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

• The encapsulation method provided beads 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.
