O-TOLYL BIGUANIDE

Description

O-Tolyl Biguanide is a potent antimicrobial agent widely utilized in skincare and personal care formulations. This synthetic compound belongs to the biguanide family, known for its broad-spectrum antimicrobial properties. Its chemical structure consists of a biguanide group attached to an o-tolyl moiety, which enhances its efficacy and stability.

In skincare applications, O-Tolyl Biguanide acts as a preservative, effectively inhibiting the growth of bacteria, fungi, and yeasts. Its ability to maintain product integrity is particularly valuable in water-based formulations prone to microbial contamination. The ingredient demonstrates efficacy at low concentrations, typically ranging from 0.05% to 0.2%, making it cost-effective for manufacturers.

O-Tolyl Biguanide exhibits excellent compatibility with various skincare ingredients and maintains stability across a wide pH range. It is especially effective against gram-positive bacteria, including Staphylococcus aureus and Streptococcus species. The compound's low molecular weight allows for easy incorporation into diverse product types, from lotions to serums.

While generally well-tolerated, some individuals may experience sensitivity. As with all preservatives, patch testing is recommended for those with sensitive skin or a history of allergic reactions to cosmetic ingredients.
