Why does Seedlings Wipes have Phenethyl Alcohol?  

The product description "Formulated without chlorine, alcohol, sulfates,
parabens, phthalates, mineral oil, animal-derived
ingredients, synthetic preservatives, synthetic
fragrances, or synthetic dyes" 

This is what the research and development team says, "Phenethyl Alcohol was needed for the safety of the wipe. It has been tested and found not only to be safe, but also non-sensitizing or irritating to the skin. Phenethyl Alcohol is not an ethyl alcohol or an isopropyl alcohol as it is chemically different. It doesn’t have any drying properties and is used as a preservative in this formula.”
