Sunscreen-Suntan Products Testing
AAL, Inc. performs complete chemical testing on raw material and the finished product of sunscreen samples.

Procedure

The raw material analysis of sunscreen ingredients includes active and etcipient chemicals. AAL analyzes these ingredients according to USP monograph. Identification is done by:

The Purity and Assay tests can also be completed by gas chromatography (GC) and high performance liquid chromatography (HPLC).

The finished products of over-the-counter sunscreen (i.e. SPF-4 to SPF-30+) active content analysis are performed by high performance liquid chromatography (HPLC). We have validated testing procedures for sunscreen analysis of active chemicals for up to seven actives.

Analysis

The active chemicals of raw material and finished products are analyzed by instrumentation such as HPLC, GC, and USP monograph.

Partial List of the chemicals commonly used:

Antiperspirant/Deodorant

The antiperspirant active ingredients are analyzed according to USP method.

Partial list of the chemicals commonly used:
