Euxyl PE 9010™ is a broad‑spectrum antimicrobial system composed of phenoxyethanol (about 90 %) and ethylhexylglycerin (around 10 %). Phenoxyethanol is an aromatic ether/alcohol that acts as the primary germicide, while ethylhexylglycerin is a glyceryl ether that reduces the interfacial tension of microbial cell membranes, enhancing the bactericidal and fungicidal activity of phenoxyethanol. This synergistic combination allows effective preservation against Gram‑positive and Gram‑negative bacteria, yeasts and molds at low concentrations. The blend is liquid, colorless and stable over a wide pH range (between 3 and 12), enabling formulators to incorporate it into lotions, creams, serums, aqueous gels and emulsions without destabilizing the formulation or altering viscosity. In addition to its antimicrobial function, ethylhexylglycerin provides mild skin‑conditioning, humectant and deodorant properties, which contribute to the sensory feel and stability of finished products.

In hair‑care formulations, the preservative performs effectively in high‑water, surfactant‑rich environments such as shampoos, conditioners, hair masks and leave‑in treatments. The preservative remains stable in the presence of salts and is effective in both anionic and cationic systems. It can withstand brief heating up to 85 °C during production and exhibits good compatibility with natural raw materials that are susceptible to microbial contamination. Because ethylhexylglycerin boosts the antimicrobial efficacy of phenoxyethanol, the overall preservative load can be reduced, which is valuable for rinse‑off hair‑care products used frequently on the scalp. Its low volatility and minimal odor help maintain fragrance integrity and product aesthetics, making it ideal for transparent gels and wet wipes. As a result, the raw material is widely adopted by cosmetic manufacturers seeking robust preservation with a favorable safety and sensory profile.
