​

The cosmetics industry is in the middle of its biggest regulatory shift in decades. MoCRA changed the rules, and brands that treat testing as a checkbox are going to feel it. Twin Arbor Labs helps cosmetic manufacturers, indie brands, and foreign facilities get ahead of compliance — with ISO 17025 accredited testing, clear reporting, and a team that actually understands the regulatory landscape you're navigating.

What We Test
​

Our cosmetics testing covers the full range of safety and quality requirements, from raw material qualification to finished product release.

  • Heavy metals (As, Cd, Hg, Pb, Cr, Co, Ni) by ICP-MS

  • Water activity

  • Active ingredient verification (hyaluronic acid, collagen, and others)

  • Shelf life and stability studies

Heavy Metal Testing Under MoCRA: A Broader Panel Than You Might Expect
​

This is where cosmetics testing diverges sharply from what most brands expect, and where a lot of manufacturers get caught off guard.

​

The standard assumption is that heavy metals testing means four elements: arsenic, cadmium, lead, and mercury. Under MoCRA, the recommended panel for cosmetics is wider. Our cosmetics heavy metals panel includes three additional elements, chromium, cobalt, and nickel, bringing the total to seven.

​

Why the expanded panel? Cosmetics are applied directly to skin, lips, and in some cases the eye area. Dermal absorption and repeated daily exposure create a different risk profile than ingestible products. Chromium, cobalt, and nickel are recognized skin sensitizers and potential carcinogens, and their presence in cosmetic formulas at elevated concentrations is a genuine safety concern, not a theoretical one. MoCRA reflects that reality.

​

We run cosmetics heavy metal testing by ICP-MS using USP <233> methodology, providing high sensitivity and specificity across complex cosmetic matrices including creams, serums, powders, lip products, and color cosmetics.

The 7-Element MoCRA Panel: Arsenic (As) · Cadmium (Cd) · Mercury (Hg) · Lead (Pb) · Chromium (Cr) · Cobalt (Co) · Nickel (Ni)

​

Applicable limits vary by product type, including lip products, eye area cosmetics, and externally applied products.
