Validation & finished product release testing

OTC Active Assay Validation 

ALS has a strong background in method development and validation for OTC Assays by HPLC, GC, or ICP. ALS can validate our in-house methods for client products or accept transfers of client methods. Our dedicated validation makes sure that validations and transfers occur quickly, so that stability and product release can be up and running as fast as possible.

ISO and USP compliant method validation

ALS clients can be assured that validations conform to USP and ISO expectations including appropriate parameters of: Accuracy, Recovery, Precision, Specificity, Linearity, Range, Limit of Detection, Limit of Quantitation, and Robustness.

OTC Active Ingredient Assays

Sunscreen and Acne product release testing are routine services of ALS. We are setup for high throughput of all common OTC actives (e.g. chemical sun filters, Titanium dioxide, zinc oxide, salicylic acid), so whether you have 5 samples or 50 samples, ALS is ready.

Method transfer and validation

When setting up for release or stability, clients have the option of performing method validation with our in-house methods or transferring in their own method. ALS accepts hundreds of client method transfers every year and knows how to make the process fast and simple.

Physical Tests

ALS regularly performs all standard physical tests such as color, odor, appearance, pH, viscosity, weight loss, and specific gravity. These can be performed for standard release if ALS is acting as a company’s central lab or as part of a stability study.

Vitamins and Supplement Testing

ALS has standard methods for testing of many common vitamins in either topical or oral forms. Common analysis include: Vitamins A, D, E, K, B (1-12), and C.
