Technology


Microencapsulation is defined as the process of entrapping targeted liquids and/or solids within a polymeric shell. Tagra Biotechnologies has a patented platform technology which is based on a physical property that does not affect the chemical properties of the encapsulated material.


Using this innovative technology, Tagra is able to create two types of state-of-the-art microcapsules for cosmetic and dermacosmetic applications:

| . RND™ Breakable Microcapsules,

|| . Transparent Unbreakable Microcapsules.

RND™ Breakable Microcapsules



Tagra has developed a patented method, RND™ Microencapsulation Technology, for non water soluble ingredients. The encapsulated compound is released upon mechanical pressure. This unique encapsulation system provides stability, efficiency and controlled/immediate release, while the encapsulation process itself, in which acrylic and/or cellulose polymers are used as encapsulants, makes it possible to overcome incompatibilities between the encapsulant and other ingredients composing the formulation.

Tagra’s unique RND™ microcapsules enable optimal isolation and are impermeable, preventing diffusion of the encapsulated material from and back into the microcapsules. Therefore, the encapsulant is optimally protected from all environmental risk factors; light, temperature, pH, oxidation and interaction with other ingredients. Although impermeable, the polymer shell is elastic in nature, and is easily ruptured upon application of mechanical pressure, such as a rubbing action


Unbreakable Microcapsules



Unbreakable microcapsules, such as Carbon Black and UV filters, in micron-size transparent shell are made of an acrylic and cellulose-based polymers. The uniqueness of this technology is that the encapsulant remain functional, avoiding nano-issues and direct contact with the skin. Neither processes involve chemical reactions; as a result, there is no risk of residual monomers or solvents.
