Why Controlled Release?
Salvona Technologies offers delivery systems that provide the following benefits:
- Enhanced stability of ingredients and extended product shelf life
- Extended release time of functional ingredients, to increase benefits, longevity, and effectiveness
- Target ingredient deposition onto a specific site to enhance efficacy and reduce side effects
- Triggered release through change in environmental factors such as water, heat, pH, ionic strength, or enzymes
- Synchronized release rates of ingredients with that of a sensory marker to convey product performance to consumers
- Enhanced bioavailability of ingredients to improve precise cell absorption
- Special performance features for market positioning that present a point of differentiation
- Cost-effective
Controlled Release Systems are used to modify the way functional and active ingredients are being delivered. These systems are smart encapsulation technologies that are used to formulate innovative and highly functional products with unique features. Some of the major virtues of controlled release delivery systems are as follows:
1). Long Lasting Release
Sustain the release of active ingredients in use so that the active is released for a longer duration of time. The technology provides longer residence for better utilization of active ingredients over time.
Actives applied normally experience an immediate, short burst in concentration followed by a rapid decline, whereas actives released from a controlled release delivery system experience a prolonged concentration at the effective level (threshold). In a passive control system, the release kinetics from the technology cannot be altered once applied. A smart delivery system is triggered and designed to enable a prolonged delivery of critical actives.
Why do we need this? Because keeping the active at an effective level ensures product efficacy and provides sustained benefits to the consumer.
2). Triggered Release
Release active ingredients on demand, triggered by environmental factors or by consumer action, is a more intelligent and smart form of controlled release systems.
Triggered delivery systems are initially dormant, however upon triggering, the release is activated to discharge the content at a much higher release rate than in a non-encapsulated scenario. The dormant effect (no or slow release) is beneficial to enhance and protect stability of non-stable actives in the formulation, until the product is triggered by the environment or by the consumer. The active ingredients remain encapsulated and protected up to time of activation. This beneficial tool can be used in many topical products, such as delivery of fragrance from deodorants, in which body moisture (sweat) can trigger the release of a pleasant smell once the consumer begins to sweat. In this case, the moisture triggers the delivery system to release a malodor countering technology accompanied with a fragrance.
3). Targeted Delivery/ Vector
Release the active materials at a desired location for localized and targeted release.
Targeted, controlled release systems assist in targeting the active to reach a specified site location where it will release its contents. The system is beneficial for products that require their applications to reach a certain area to perform better, such as a drug attaching to cancer cells for cancer therapy; another example is deposition and penetration of a hair regrowth agent into the hair follicles; or even anti-aging applications, where the active must reach deep within the skin dermis before truly becoming effective.
What Are Nanotechnology Delivery Systems?
Delivery systems at the near-atomic, or less than 1,000 nanometers typically 0.1nm to 100nm constitute nanotechnology. Particles with diameter of 100-1000nm are considered sub-micron systems.
