Research & Development

Product Quest takes pride in the high quality and innovation found in every formula we produce for our customers. Our experienced and knowledgeable Research and Development (R&D) scientists use cutting edge technologies to create an ever-expanding library of unique and customizable formulas to meet your expectations. When there is a need for new formulations, the R&D team can achieve a quick turnaround with the readily available raw materials and ingredients maintained in our facilities.

The in-house Quality Control (QC) laboratory and Reference laboratory are an essential part of the R&D formula development efforts and regulatory compliance (cGMP) from conception to commercial production to assure quality and timeliness during the formula development phase and beyond.


Our formulation capabilities include:

  • OTC formulations
  • Cosmetic formulations
  • National Brand Equivalent formulations
  • Transfer technology and formula evaluations

Analytical Methodology

The analytical expertise of the QC Lab covers an extensive variety of products and technologies to support all kinds of analytical needs, including:

  • Liquid Chromatography (HPLC)
  • Gas Chromatography (GC)
  • Titrimetry
  • Viscosity Tests
  • Specific Gravity Tests
  • pH Tests
  • USP methods
  • Wet chemical methods
  • Reference Lab (advanced methodology): ICP, AAS, HPLC-MS, GC-MS, etc.


We ensure adherence to quality standards throughout the entire product development and manufacturing process through:

  • Written procedures (SOPs)
  • Quality documentation
  • Approval and Release procedures
  • Validation activities
  • Stability studies and Expiration dating
  • Regulatory Affairs and Compliance activities

Pilot Batching

R&D has two suites equipped with all necessary capabilities to produce pilot scale batches of products required for stability tests and other studies. Pilot scale production is utilized in line fill studies to ensure acceptability of the components used to package commercial product as well as for process scale up to commercial manufacturing.

A Conversation with Regina Lim VP, PQ R&D

Q: How does R&D fit in the manufacturing process?
A: During the manufacturing process, Research and Development provides the guidance needed for formula validation, as well as technical support necessary for monitoring a product throughout its lifecycle.

Q: I don’t have a formula, can you help me?
A: Yes, we can develop products specific to your requirements. We have the capacity and resources.

Q: I have a formula, but can you help me improve it?
A: Absolutely yes! We can improve your formula as you desire.

Q: How many chemists are on staff?
A: We have a total of 9 chemists, between the Florida and North Carolina facilities.

Q: What are your formulation specialties?
A: Topical products both OTC and/or Cosmetic. The Ei site has extended capabilities that include Pharma, NDAs, etc.

Q: I’m considering making the change to PQ. How can I be sure not to lose anything – quality, time, etc. – in the transition?
A: Product Quest is an FDA registered facility that manufactures products under the Good Manufacturing Practices (GMP) compliance. We have an outstanding professional management team with extensive experience in the industry.
