Transdermal Formulation Thickness Testing

Inquiry

The thickness oftransdermal formulations not only affects their appearance but is also directlyrelated to their drug release performance and skin fit. CD Formulation has been researching the field of transdermal formulation for decades has richprofessional knowledge and can provide you with professional testing services.

About Transdermal Formulation Thickness Testing

The thickness of transdermal formulations is closely relatedto their drug-release properties. Appropriate thickness can ensure that thedrug is released at a constant rate. A preparation that is too thick may resultin a reduced fit and reduce the penetration efficiency of the drug; a patchthat is too thin may not provide sufficient support, causing the patch to slideor fall off the skin.

What Can We Offer

Transdermalformulation thickness testing is of vital significance in formulationdevelopment, production, and quality control processes. CD formulation canprovide you with the following services:

Quality control

Ensure productconsistency and uniformity. By measuring the thickness of transdermal formulation at different locations, we can evaluate whetherthe product is uniform and whether there are defects in varying thicknesses.

Performance evaluation

Evaluate drugrelease rate. The thickness of transdermal formulation can affect theformulation and release rate of the drug, so we can indirectly evaluate thedrug release performance through thickness testing.

Our Workflow of Transdermal Formulation Thickness Testing

Our transdermal formulation thicknesstesting process is as follows:

Our Capabilities for Testing Transdermal Formulation Thickness

Thickness testingof transdermal formulation usually requires the use of some specializedinstruments to ensure the accuracy and reliability of measurement. We canprovide you with the following commonly used transdermal formulation thicknesstesting instruments:

Instrument Description
Micrometer A micrometer is a precision measuring tool capable of measuring the thickness of an object to a few decimal places.
Mechanical thickness gauge Thickness gauge is an instrument specially used to measure the thickness of materials.
Optical thickness gauge For some transparent transdermal formulations, optical measuring instruments such as laser rangefinders or optical interferometers can be used to measure their thickness.

Why Choose Us for Transdermal Formulation Thickness Testing?

  • Our measuring instruments use advanced sensors and algorithms to achieve high-precisionthickness measurements.
  • Our measuring instruments have a repeatability of up to 0.3 microns, which can meet theprecise measurement of subtle changes in material thickness.
  • Our measuring instruments are suitable for thickness measurement of a variety of materials,covering a wide range of measurements.
