"Ethylene Glycol Monophenyl Ether" or "Phenoxyethanol" is a synthetic preservative that is commonly used in cosmetics, skincare, and personal care products. When added to a formula, it helps prevent microbial growth and extending product shelf life by controlling bacteria, yeast, and mold. This ingredient disrupts their cellular process, primarily by interfering with their DNA and RNA synthesis effectively preventing their growth and reproduction within a product, thus acting as a preservative against microbial contamination.
Phenoxyethanol occurs naturally in green tea and plants like chicory but it is also produced in laboratories by reacting phenol and ethylene oxide at high temperatures and pressures. In cosmetics, this synthetically produced ingredient is sometimes called a “nature's identical” chemical.
While non-irritating and hypoallergenic, it's very suitable for sensitive skin and compatible with various formulations and pH levels. It has the ability to remain low in toxicity which makes it safe for use in concentrations up to 1%. Studies have shown that using phenoxyethanol in concentrations higher than 1% can lead to increased skin irritation, which is why most cosmetic companies adhere to this limit.
Even at 1%, phenoxyethanol is considered an effective preservative against bacteria and fungi, making it a widely used ingredient in cosmetics. Also known as "Rose Ether", it's a colorless, oily glycol that carries anti-inflammatory properties that help soothes and calms skin, while adding protection against oxidative stress.
Extensive research by regulatory bodies like the Cosmetic Ingredient Review (CIR) has found no evidence linking it to cancer when used at standard concentrations in cosmetic products; this means that at the levels typically found in skincare items, it does not appear to have carcinogenic properties and is generally considered noncancerous.
General Warnings
Irritation and allergic reactions: May cause skin irritation, redness, or itching.
Eye irritation: Avoid contact with eyes; may cause conjunctivitis or burning sensations.
Respiratory issues: Inhalation can cause respiratory problems.
Pregnancy and breastfeeding: Use with caution; consult a healthcare professional.
Regulatory Guidelines
The Globally approved recommended maximum of Phenoxyethanol in cosmetics is 1%.
Precautions
1. Use in moderation (typically 0.5-1% concentration).
2. Avoid contact with eyes or mucous membranes.
3. Patch testing recommended.
4. Skin contact irritation: Wash with soap and water.
5. Eye contact irritation: Rinse thoroughly with water.
6. Inhalation irritation: Move to fresh air.
Overall, Phenoxyethanol is a reliable and efficient preservative, enhancing product safety and shelf life.
