Phenoxyethanol dosage

Phenoxyethanol analysis allows for verification of the concentration of this preservative, commonly used in cosmetic and hygiene products .
Present in numerous formulations (creams, lotions, wipes, shampoos, makeup removers), phenoxyethanol acts as an antimicrobial agent to preserve the stability and microbiological safety of the finished product.
In accordance with Regulation (EC) No 1223/2009 , its concentration is limited to 1% in cosmetic products, hence the need for precise and regulatory analytical control .

Analytical methods

The assay is performed using robust and sensitive chromatographic techniques:

• GC-FID (gas chromatography with flame ionization detection) : ideal for the quantification of volatile and semi-volatile compounds,
• GC-MS (gas chromatography coupled with mass spectrometry) : for the specific identification of phenoxyethanol in complex matrices,
• HPLC (high-performance liquid chromatography) : for analysis in aqueous or viscous products such as creams and gels.

These methods are implemented according to validated standards (ISO 17025, European Pharmacopoeia, or validated internal method).

Industrial applications

Phenoxyethanol analysis is applicable to a wide range of products:

• Cosmetics : moisturizing creams, makeup removers, micellar lotions, shower gels, makeup, wipes, etc.
• Hygiene products : cleaning solutions, mild disinfectants, hair care.
• Regulatory controls : verification of compliance with European requirements and the REACH regulation.

Matrices analyzed

• Finished cosmetic products (emulsions, gels, solutions, sprays)
• Cosmetic raw materials
• Micellar waters and facial cleansers
• Personal hygiene products

Further analyses recommended

For complete control of the safety and stability of cosmetic products , YesWeLab recommends:

• Sterility test : verification of the absence of viable microorganisms,
• Stability test : evaluation of the formula's durability,
• Oxidation stability of fats and oils : control of rancidity of lipid bases,
• Study of the photostability of a sunscreen product : measurement of the stability of UV filters and light-sensitive ingredients.
