Description:

Methylpropanediol is a synthetic diol used as a solvent, humectant, and viscosity-decreasing agent. It helps improve the texture and absorption of personal care products such as lotions, serums, and hair care formulations. It can be petroleum-derived or produced from bio-based feedstocks.

Health concerns:

Low Health Concerns

Current research suggests ingredient may be safe for use.

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.
