Independent toxicological evaluation
Signed assessments of ingredient and finished-product safety. Hazard characterization, dose–response review, and uncertainty analysis structured for regulator and retailer scrutiny.
Independent scientific consulting · Exposure-based risk assessment
The Agyekum Group (AG) provides independent scientific consulting across cosmetics, personal care, consumer products, medical devices, pharmaceuticals, industrial chemicals, and environmental health. We deliver exposure-based risk assessment, toxicological evaluation, regulatory strategy, safety substantiation, and scientific governance to support product development, market access, regulatory compliance, and litigation.
The same exposure-based scientific methodology underpins every engagement, regardless of industry, product category, or regulatory framework. Our approach integrates toxicology, exposure science, risk assessment, and regulatory strategy to deliver scientifically defensible decisions across regulated industries.
Platform access available below.
Platform · supports the consulting practice
ToxIntel is Aᴳ’s enterprise scientific safety intelligence platform — a distinct product built to operationalize toxicological assessment, regulatory workflows, scientific governance, and product stewardship. It supports, but does not replace, the consulting practice.
Practice capabilities
Five practice areas anchor every engagement. Each is signed by a named toxicologist and documented for the next reader — regulator, retailer, or court.
Signed assessments of ingredient and finished-product safety. Hazard characterization, dose–response review, and uncertainty analysis structured for regulator and retailer scrutiny.
Quantitative SED / NOAEL / MoS / BMD analyses per population band. Pathway-specific exposure modelling for dermal, oral, inhalation, and mucosal use.
Product-level safety substantiation across cosmetics, personal care, fragrance, ingestibles, and adjacent consumer categories — fit for MoCRA, EU 1223, and IFRA contexts.
Toxicology-led regulatory strategy and litigation-aware documentation. Independent expert review, Prop 65 exposure framing, and enforcement-relevant scientific narrative.
Aᴳ’s in-house platform — contaminant surveillance, formulation review, compliance passport export, and continuously updated regulatory context. Made available to enterprise clients.
Federal Register, FDA, CPSC, OEHHA, and FTC signals tracked and interpreted — surfaced below in Toxicology Watch and integrated into client briefings.
Frameworks & methodology
Every Aᴳ evaluation references the same regulatory frameworks and scientific methodologies a competent authority, retailer, or court would reference. We are explicit about which framework applies, where its boundary lies, and what evidence the engagement produces.
Regulatory frameworks
Modernization of Cosmetics Regulation Act
U.S. cosmetic facility & product registration, adverse-event reporting, safety-substantiation evidence requirements.
Regulation (EC) No 1223/2009

Claim & label substantiation
Defensible documentation of safety, performance, and regulatory claims for retailer and litigation contexts.
All assessments are signed by a named toxicologist · documented for regulatory, retailer, and litigation contexts.
01 — Scope
Toxicology and risk assessment aligned with EU, FDA, and international frameworks where safety substantiation and exposure analysis are required.
Evaluation of formulations and ingredients against exposure-based safety criteria and documentation standards applied in retailer governance.
Independent toxicological analysis of chemical exposure, dose–response, causation, and complex data — structured to withstand legal scrutiny.
Hazard characterization, exposure considerations, and regulatory status review of ingredients in support of downstream use.
02 — Scientific practice
Aᴳ delivers scientific consulting across cosmetics, personal care, consumer products, pharmaceuticals, medical devices, industrial chemicals, and environmental toxicology. The same exposure-based methodology, board-certified oversight, and documentation discipline scales across every practice we engage.
ToxIntel is our enterprise scientific safety intelligence platform — a distinct product that operationalizes many of these workflows. It supports, but does not replace, the consulting practice.

01 · Practice
AvailableFoundational scientific assessment across every regulated category we serve.
Independent toxicological evaluation, exposure-based risk assessment, and defensible safety opinions — the scientific core of every Aᴳ engagement, regardless of product class. The practice explicitly supports multi-pathway and aggregate exposure evaluation across dermal, inhalation, oral, and incidental-ingestion routes; pathway aggregation is performed only when scientifically appropriate — not by summing unrelated estimates.
