For adults (men and women), dipropylene glycol is usually safe in skin products when used as intended. It’s a common ingredient with low overall hazard in safety reviews.
Use products that are made by reputable brands and follow the product directions. If you try a new product, test a small patch of skin first. If you have sensitive skin, choose formulations labeled for sensitive skin and rinse off if you get redness or stinging.
There are two main things to watch for: 1) Some safety reviews note possible contamination with manufacturing by‑products (ethylene oxide and 1,4‑dioxane) — these come from how the chemical is made, not the chemical itself. 2) A few reports show mild skin or eye irritation and rare contact allergy. The contamination concerns are listed by public health reviews and regulatory summaries (for example: Environment Canada and the U.S. National Toxicology Program); irritation findings are noted in cosmetic ingredient reviews; and contact allergy was reported in a 1995 clinical report. Avoid using products containing this ingredient on broken or inflamed skin, stop use and rinse if you develop irritation, and seek medical advice for persistent reactions.
