IODOPROPYNYL BUTYLCARBAMATE

TL;DR. This ingredient is a preservative, used mainly for antifungal protection against yeast and mold in water-containing formulas. It is often paired with a broader-spectrum preservative for stronger bacteria control.

What does IODOPROPYNYL BUTYLCARBAMATE do in a cosmetic formula?

This ingredient is a preservative, used mainly for antifungal protection against yeast and mold in water-containing formulas. It is often paired with a broader-spectrum preservative for stronger bacteria control.

Is IODOPROPYNYL BUTYLCARBAMATE clean?

From a clean-beauty perspective, it is a high-friction preservative because it can trigger contact allergy in some users and is tightly concentration-restricted in the EU. Many stricter clean standards exclude or heavily limit it, especially in leave-on and spray formats.

Is IODOPROPYNYL BUTYLCARBAMATE sustainable?

This material is synthetic and typically petrochemical-derived, used at trace levels rather than as a bulk ingredient. Its halogenated structure and aquatic impact profile make it a weaker fit for biodegradability-centered frameworks.

Is IODOPROPYNYL BUTYLCARBAMATE COSMOS-approved?

It is not permitted under COSMOS-natural or COSMOS-organic standards as a cosmetic preservative. From a Green Chemistry perspective, it has limited alignment because it is synthetic, halogenated, and not known for ready biodegradation.

How does IODOPROPYNYL BUTYLCARBAMATE work chemically?

The molecule is a small halogen-containing carbamate with an acetylenic side chain, which gives strong activity against fungi at very low dose. Regulatory use limits are commonly around 0.02% in rinse-off products and 0.01% in many leave-on products, with format and age-related restrictions in some regions.
