Description:

Dipropyl isocinchomeronate, also known as MGK Repellent 326, is a synthetic insect-repellent compound historically used in formulations designed to discourage mosquitoes, flies, and other biting insects. It has been used in skin-applied and other repellent products, although its current availability and permitted uses vary. Exposure may occur through application of products containing the compound or contact with treated materials.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Ecotoxicity

May be toxic to ecosystems and wildlife.

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
