Linatural™ is a multifunctional, broad-spectrum antimicrobial system formulated from naturally derived ingredients designed to protect cosmetic and personal care formulations from microbial contamination while simultaneously providing skin-conditioning benefits. The system combines three naturally sourced components — Pentylene glycol, Propanediol, and Phenethyl Alcohol —, each contributing complementary functionality. Pentylene Glycol, derived from sugar cane or corn cobs, acts as both a skin-conditioning agent and an antimicrobial compound with strong activity against bacteria and yeast. Propanediol, sourced from corn, functions primarily as a humectant and moisturizer while also enhancing the antimicrobial performance of the system against fungi and bacteria. Phenethyl Alcohol, also naturally derived from corn, contributes bactericidal activity and moderate control against yeasts and molds, while additionally serving as a fragrance component.
Together, these ingredients form a clear, water-white liquid antimicrobial system that offers broad-spectrum protection while adding moisturizing and emollient benefits to formulations. The combination provides effective microbial control while maintaining a low odor profile and avoiding traditional preservatives. The ingredient is designed to function across a wide pH range of approximately 3 to 10. Beyond preservation, the system contributes additional functional value through its conditioning and humectant properties, supporting improved skin feel and hydration within finished formulations. Its natural origin and multifunctional design allow it to support modern formulation strategies focused on simplified ingredient systems and environmentally conscious raw materials. The product is also described as readily biodegradable.
