Our Capabilities in Action
WTD Duo — Professional-Grade At-Home Teeth Whitening System
Traditional whitening strips use either hydrogen peroxide, PAP, or other peroxygen compounds to whiten. At lower concentrations (less than 12%), these whitening strips require extended contact or wear time to be effective. This is why most home whitening systems require long wear time of 30 minutes to 1 hour, and repeated sessions to truly produce noticeable results.
Sensitivity-Free PAP Teeth Whitening Strips
Includes 14 individually packaged & on-the-go whitening treatments
Traditional whitening strips use hydrogen peroxide, which can cause sensitivity and may irritate gums.
Instead, WTD! PAP Whitening Strips are peroxide-free and use the safe and clinically-proven active whitening ingredient PAP (Phthalimidoperoxycaproic Acid). PAP works similarly to peroxide, but it breaks down only the stains & discoloration.

WTD! Advanced 3D HP Whitening Strips are clinically proven to whiten up to 24 shades in 30 applications! To make it even more impressive, WTD! HP Whitening Strips are effective for up to 3 years – no other competitor can even come close to this long shelf life.
Frequently Asked Questions
What oral care products does Atrium Scientific manufacture?
Atrium Scientific manufactures PAP (phthalimidoperoxycaproic acid) whitening strips, hydrogen peroxide whitening strips, teeth whitening gels, private label whitening systems, and custom oral care formulations including toothpaste. All products are manufactured at an FDA-registered, cGMP-compliant facility in Garden Grove, California.
What is the difference between PAP and hydrogen peroxide whitening strips?
PAP whitening strips use phthalimidoperoxycaproic acid, a peroxide-free bleaching agent that whitens without causing tooth sensitivity. Hydrogen peroxide (HP) whitening strips use a clinically proven bleaching mechanism for faster, stronger whitening. Atrium manufactures both technologies and can formulate custom concentration levels for your target market and regulatory requirements.
Can Atrium Scientific create a private label whitening product for my brand?
Yes. Atrium offers private label oral care manufacturing using stock formulations that enable a faster path to market and lower upfront investment. Custom formulation development is also available for brands seeking proprietary formulas, unique active ingredient concentrations, or novel delivery formats. Minimum order quantity is 3,000 units.
Are Atrium’s whitening strip products compliant with U.S. dental regulations?
Atrium’s whitening products are manufactured at an FDA-registered facility under cGMP standards. Formulations can be developed to comply with FDA cosmetic product guidelines and OTC drug monographs where applicable. Atrium’s team provides regulatory guidance as part of the formulation development process.
What is the minimum order quantity for oral care contract manufacturing?
The minimum order quantity (MOQ) for oral care products at Atrium Scientific is 3,000 units — one of the lowest MOQs available from a U.S.-based oral care contract manufacturer. This low threshold makes Atrium accessible to early-stage brands and DTC companies testing new oral care formulations.
