What Is Nano-Complex Technology and How Does It Work in Oral Care Formulations?
In pharmaceutical terms, a nano-complex refers to a complex or combination of substances that are structured at the nanoscale level. It involves the formulation of active pharmaceutical ingredients (APIs) or therapeutic agents in a nano-sized delivery system.
Nano-complexes are designed to have specific properties and advantages compared to conventional drug delivery systems. By manipulating the size, shape, and composition of the particles or structures, nano-complexes can enhance the bioavailability, stability, and targeted delivery of drugs. They can also improve solubility, prolong drug release, and potentially overcome various barriers in drug delivery, such as crossing biological membranes or reaching specific tissues or cells.
Nano-complex technology gives pharmaceutical and oral care formulations a level of active ingredient control that conventional delivery systems cannot match. By structuring active pharmaceutical ingredients at the nanoscale level, formulations can be designed using lipids, polymers, or inorganic nanoparticles to match the specific delivery requirements of each product — whether the goal is faster absorption, extended release, or improved stability across varying storage conditions.
Atrium’s nano-complex technology works by combining active compounds — including hydrogen peroxide and phthalimidoperoxycaproic acid — with a precisely selected blend of natural, adhesive polymers. These charged polymers are engineered to bind directly to tooth enamel, creating a sustained-release bond that keeps active ingredients working at the treatment site over time rather than being washed away immediately. This mechanism is what separates a well-engineered oral care formulation from one that looks good on a label.
Where formulation requirements demand it, our compositions can also incorporate desensitizing agents, antibacterial agents, flavoring agents, and enzymes to support broader oral health outcomes alongside the primary whitening or treatment function.
This approach to nano-complexation gives brands developing oral care products, teeth-whitening systems, and active-delivery formulations a manufacturing partner who understands the science behind the format and has the in-house process capability to produce it consistently at commercial scale in our FDA-registered, cGMP-compliant facility in California.
What are the benefits of nano-complexes for oral health?
Nano-complexes offer several potential benefits when it comes to delivering active ingredients for oral care purposes. Here are some of the advantages associated with the use of nano-complexes in oral care:
Enhanced Bioavailability
Nano-complexes can improve the bioavailability of active ingredients by increasing their solubility and stability.
This means that a higher concentration of the active ingredient can be delivered to the desired site in the oral cavity, improving its effectiveness.
Targeted Delivery
Nano-complexes can be designed to target specific areas in the oral cavity, such as the teeth or gums.
By encapsulating the active ingredients within nanoscale structures, they can be directed to the intended site, allowing for precise delivery and localized treatment.
Extended Release
Nano-complexes can provide sustained or controlled release of active ingredients over an extended period.
This is beneficial for oral care products as it allows for a longer duration of action, ensuring that the active ingredients stay in contact with the teeth or gums for a prolonged period, promoting their effectiveness.
How Nano-Complex Encapsulation Protects Active Ingredients in the Oral Cavity?
Nano-complex encapsulation protects active ingredients from degradation caused by saliva, enzymes, and other harsh conditions inside the oral cavity. By shielding actives within nanoscale structures, the formulation preserves both stability and efficacy throughout the delivery process, ensuring the active compounds reach their intended target site intact and at full therapeutic strength.
Better Taste, Better Texture, and Stronger User Compliance for Oral Care Products
Nano complexes can enhance the sensory attributes of oral care products, such as taste and texture, making them more pleasant for patients to use. This can improve user compliance and encourage regular use of oral care products, leading to better oral health outcomes.
