LC-MS for Personal Care: Skin Extracts & Fatty Acids

Q: Can you verify our label claims?

Yes: the active is quantified against label strength in the finished formulation with a documented method and stated acceptance criteria, batch to batch. That is the same discipline this lab applies to investigational drugs, which is the point of coming here for it.

Q: Do you test for microbial contamination or run safety toxicology?

No, and we will not pretend to: this is a quantitation and immunoassay lab, not a microbiology or in vivo toxicology facility. We measure actives, preservatives, ingredients and biomarkers. Pathogen testing and safety tox belong with labs built for them, and we will say so in the first call rather than after a quote.

Q: How does stability testing work here?

Your stability protocol defines the conditions and pull schedule; we quantify the active at every pull with the same validated-grade method, so degradation is measured rather than assumed. The output is a dataset your expiry dating and claims can actually cite.

Q: Can you support claims from consumer or clinical studies?

Yes. Skin extracts, swabs and biological samples from consumer studies are quantified by LC-MS/MS, and biomarker endpoints run on ELISA, MSD, Luminex and flow panels: the same platforms this lab uses for clinical trials. Before-and-after claims read differently when the numbers behind them were measured like a trial.

Q: Will our brand stay confidential?

Yes, by default and by CDA. The global consumer goods leaders who test here are never named in our marketing, and that policy is why they keep testing here. Your formulation, your data and your name stay yours.

Q: What if our product edges into OTC or drug territory?

Then you are already in the right building: sunscreen-style monograph actives and drug-adjacent questions can move to regulated tiers, GLP practice and clinical-grade work without changing labs. Consumer labs cannot make that offer; a bioanalytical CRO can.

Q: Is there a minimum project size?

No. One formulation and one analyte is a fine first project, priced per assay and per sample at the research tier. Recurring batch verification gets standing-method pricing, and several of the lab’s longest consumer relationships started with a single question.

What Personal Care Testing Covers

The instruments and scientists that quantify investigational drugs for FDA-inspected studies also measure your actives, preservatives and claims, with no second tier for consumer work.

Label Claim Verification For Active Ingredients

The active quantified against label strength in the finished formulation, batch to batch
Documented methods with stated acceptance criteria, so the number holds under challenge

Preservative And Ingredient Level Quantitation

Preservative levels and key ingredients confirmed across formulations and raw materials
Misdosed or missing ingredients surface at this bench, not in a retailer’s audit later

Stability Of Actives Through The Full Shelf Life

Time-point samples from your stability protocol quantified as they pull, arm by arm
Degradation tracked against the label claim, so expiry dating rests on measured data

Claim Support From Consumer And Clinical Studies

Biomarkers in samples from consumer studies, run on ELISA, MSD, Luminex and flow panels
Quantitative endpoints behind before-and-after claims, measured like a clinical trial

Skin Extracts And Penetration Study Samples

Actives, fatty acids and metabolites quantified in skin extracts by LC-MS/MS methods

Global consumer goods leaders run personal care programs on this lab’s benches beside the 100+ sponsors here every year, on the same twelve LC-MS systems and immunoassay fleet, unnamed by design.
Research-tier pricing with no minimum batch and results in two to four weeks on small projects, so a single-formulation question costs what a single-formulation question should.
Every method is documented with stated acceptance criteria under the discipline of a five-times FDA inspected lab, so a challenged claim is defended with data, never with adjectives.

What Does Personal Care Testing Cost?

Research-tier pricing, per assay and per sample, with no minimum batch size and method adaptation often done in days from the in-house library. The quote itemizes exactly what each number includes, and a senior scientist replies within two business days.

No Project Is Too Small To Start

Single-formulation questions are welcome; several long-running consumer programs here began with one. The quote you approve is the price you pay, and recurring batch work gets standing-method pricing that rewards the repeat.
