Iodopropynyl butylcarbamate (IPBC) is a synthetic preservative commonly used in cosmetic and personal care products. It is a white to light yellow powder that is soluble in water and has a slightly sweet odor. IPBC is used to inhibit the growth of bacteria, yeast, and mold in products and extend their shelf life. It is synthesized through a chemical process using various starting materials, including iodine, propynol, and butylurea. These starting materials are typically derived from petrochemical sources.

• Broad-spectrum protection: IPBC is effective against a wide range of microorganisms, including bacteria, yeast, and mold, making it a popular preservative in many products.

• Low toxicity: IPBC has a low toxicity profile and is considered safe for use in cosmetic and personal care products at low concentrations.

• Stable: IPBC is stable under a range of conditions, including varying temperatures and pH levels, making it a reliable preservative for a variety of products.

• Water-soluble: IPBC is water-soluble and can be easily incorporated into many different types of formulations.

While IPBC is generally considered safe for use in cosmetic and personal care products, it can cause skin irritation and allergic reactions in some individuals. Therefore, it is important to use products containing IPBC as directed and discontinue use if any adverse reactions occur.
