Formulation Lab

Built for the formulator's bookmarks bar.

Per-active analytical scope, INCI verification, recommended use levels, carrier-compatibility guidance, and stability data — the references a cosmetic chemist actually wants on tap when designing a serum, cream, or eye-area finished product.

Clean unbranded laboratory beakers in side-lit moody studio composition — representative of the analytical rigour Pepoderma applies to every cosmetic-grade peptide active before release.

Sample lot PD-26-A0517 · Copper Tripeptide-1 · Pepoderma atelier · Shanghai

Batch evidence, clearly scoped.

Ask sales for the COA matched to the offered or supplied batch. It records the tests actually completed. INCI support, carrier stability, copper-content work, raw data, and independent reports are project-specific scopes.

Analytical methods · available scope

Define the right panel for the active.

The methods below are a formulation-oriented capability map, not a promise that every line appears on every COA. Ask sales for the certificate matched to the offered or supplied batch; it records the tests actually completed. Any carrier study, expanded panel, or reporting requirement is scoped before quote.

Test	Method	Target	Why we run it
RP-HPLC purity	C18 gradient with UV detection at the active's working wavelength	≥ 98.0 % (cosmetic-grade spec)	Resolves the synthesised active from synthesis truncations and late-eluting impurities when this method is part of the agreed batch scope.
ESI-MS identity	ESI-MS, monoisotopic [M+H]⁺ vs. theoretical	Confirmed (±0.5 Da)	Confirms molecular weight of the peptide active matches the labelled INCI molecule.
INCI verification	Database and document review when included in scope	Project-specific	Confirm the applicable INCI name, CAS, and supporting SDS with sales before using the information in a brand-notification workflow.
Water content (Karl Fischer)	Coulometric KF	≤ 8.0 % (lyophilised powder)	Lyophilisation control. Out-of-spec water shortens the working shelf life of the active in finished products.
Counter-ion	Ion chromatography	Acetate (default)	Acetate is the default cosmetic-grade salt; alternative counter-ions are documented on the SDS when present.
Stability — reference aqueous serum	Time-course RP-HPLC at 25 °C / 40 °C over 12 months	Documented decay envelope; ≥ 90 % retention at 6 months / 25 °C	Establishes a baseline shelf-life expectation in a representative cosmetic carrier. Brand-specific carrier-stability is scoped per inquiry.
Photo-stability flag	Light-stress study (ICH Q1B-style)	Flagged on the lot report when relevant	Active-class-specific. Copper-peptide actives in particular need light-protected packaging guidance for the brand owner.

Documentation

Everything a cosmetic R&D chemist needs.

Ask sales for the COA matched to the offered or supplied batch. The items on the right are available documentation types, not a fixed bundle promised for every active. Raw data, stability work, INCI support, or a separate independent-laboratory report must be confirmed in the written project scope.

Lot Report

The matching batch COA records the analytical items actually completed for the named lot.

RP-HPLC chromatogram

Raw chromatogram showing main peak + integrated impurity profile.

ESI-MS spectrum

[M+H]⁺ confirmation within ±0.5 Da of theoretical INCI molecule.

Stability data

Ask which lot-specific or reference stability evidence is available; any brand-carrier study is scoped and quoted per inquiry.

INCI + CAS SDS

Confirm the applicable INCI, CAS, and SDS record for the offered active before relying on it in a notification workflow.

Carrier-compatibility note

Active-specific flags: chelator-free water, working pH range, reductive-antioxidant placement, preservative-system compatibility.
