For adults, this preservative is generally safe when it is used in finished skincare or cosmetic products at the amounts set by manufacturers. Health concerns are rated low overall. The main cautions relate to workplace exposure and rules about how companies can use it.
Use products that already contain the ingredient rather than handling the raw chemical. Follow product directions. If you have sensitive skin, do a small patch test on your inner arm before regular use. Stop use and see a doctor if you get redness, swelling, or itching. If you are pregnant, nursing, or have a chronic skin condition, check with your healthcare provider if you are unsure.
Avoid working with the concentrated raw chemical yourself (this is for manufacturers and workers) — workplace exposure limits are noted in the ingredient assessment (EU GHS workplace guidance). Some product-certification programs restrict this ingredient unless manufacturers supply extra safety documentation (industry product-restriction notes). There are also industry recommendations about maximum concentrations in products (Cosmetic Ingredient Review). Watch for skin irritation or allergic reactions (though overall allergy risk is low). The ingredient data also notes low environmental concern (Environment Canada).
