Iodopropynyl Butylcarbamate

Description

Iodopropynyl Butylcarbamate (IPBC) is a synthetic preservative widely used in cosmetics and personal care products. This compound is highly effective against fungi, yeasts, and molds, making it valuable for extending product shelf life and maintaining formulation integrity. IPBC works by inhibiting microbial growth through its iodine-releasing mechanism.

Typically employed at concentrations between 0.02% to 0.1%, IPBC offers broad-spectrum antimicrobial protection. Its efficacy allows for reduced use of other preservatives, potentially minimizing skin irritation risks. IPBC is particularly useful in leave-on products like lotions, creams, and makeup, as well as rinse-off items such as shampoos and body washes.

Despite its benefits, IPBC has faced scrutiny due to potential allergenicity in some individuals. It's classified as a moderate contact allergen, with increased risk in damaged or abraded skin. Regulatory bodies, including the EU Cosmetics Regulation, have imposed restrictions on its use, especially in products for children under three years old.

When formulating with IPBC, it's crucial to consider its pH sensitivity, optimal efficacy range, and potential interactions with other ingredients. Proper usage within regulatory limits can provide effective preservation while minimizing adverse reactions.
