Iodopropynl Butylcarbamate ●
TL;DR. This ingredient is a synthetic preservative used mainly to control yeast and mold in water-containing formulas. It is often paired with other preservative types because its bacterial coverage is more limited.
What does Iodopropynl Butylcarbamate do in a cosmetic formula?
This ingredient is a synthetic preservative used mainly to control yeast and mold in water-containing formulas. It is often paired with other preservative types because its bacterial coverage is more limited.
Is Iodopropynl Butylcarbamate clean?
From a clean beauty perspective, it has clear friction because it is a known sensitizer at higher exposure and is tightly concentration-limited in several markets. Many clean standards flag it due to halogenated chemistry and use restrictions, especially in leave-on, lip, oral, and aerosol formats.
Is Iodopropynl Butylcarbamate sustainable?
This material is synthetic and not a renewable-leaning ingredient. Its biocidal design and wastewater profile give it weaker environmental alignment than simpler, readily biodegradable preservative systems, even though it is used at very low levels.
Is Iodopropynl Butylcarbamate COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry perspective, it has weak alignment because it is synthetic, halogenated, restriction-heavy, and not a strong fit for readily biodegradable, low-concern preservative design.
How does Iodopropynl Butylcarbamate work chemically?
The molecule is a halogenated carbamate preservative with strong antifungal activity, commonly used in the low ppm range, with regulatory caps around 0.01% to 0.02% depending on product type and region. It performs best in mildly acidic to neutral formulas and is generally not suited to high-heat processing, strongly alkaline systems, or formats where inhalation exposure is expected.
