Transdermal Formulation Moisture Absorption Rate Testing

The purpose of testing the moisture absorption rate of transdermal formulation is mainly to evaluate the preparation's ability to absorb and retain moisture. By testing the moisture absorption rate of the preparation, the safety and effectiveness of the preparation can be ensured during storage, transportation and use. CD Formulation can provide you with professional moisture absorption testing services for transdermal preparations.

About Transdermal Formulation Moisture Absorption Rate Testing

If the moisture absorption rate of the drug is too high or too low, it may affect the performance of the patch. In addition, patches may be exposed to different humidity conditions during storage and transportation. If the water absorption rate of the preparation is too high, it may cause it to deteriorate or lose its efficacy. By testing the hygroscopicity of a formulation, its stability under different humidity conditions can be assessed to determine appropriate storage and transportation conditions.

What Can We Offer

Our commonly used methods for testing the moisture absorption rate of transdermal formulation are as follows:

Static method

Place a drug sample of known mass in a specific humidity environment (usually using a saturated salt solution or a humidity controller). After a certain period of time, take out the drug sample and weigh it immediately. The moisture absorption rate is determined by calculating the change in weight.

Dynamic method

Weigh the drug sample continuously for a period of time under specific humidity conditions, and then calculate the moisture absorption rate.

Specific gravity method

Put the drug sample in a water-free container and weigh it accurately. Then put the container in a constant humidity environment to reach the relative humidity required by the drug sample. After the drug is fully humidified, take out the container and weigh it again immediately. The moisture absorption rate is calculated by the difference between the two weighing.

Drying method

Dry the drug sample under constant temperature and humidity conditions, then weigh it and calculate the moisture absorption rate.
