General description

Stearyl Alcohol is added as a stiffening agent in cosmetics and pharmaceutical formulations. It is also utilized to enhance the water-holding capacity of ointments. Its other applications include the use in controlled-release tablets, suppositories, and microspheres.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Application

Stearyl Alcohol may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by gas chromatography.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
