常见问题 （Frequently Asked Questions）

1% limit, blend systems and processing conditions

What is the use limit of phenoxyethanol in cosmetics?

The Chinese Safety and Technical Standards for Cosmetics and the EU Cosmetics Regulation both list phenoxyethanol as a permitted preservative at a maximum of 1.0%. Most formulas use 0.3% to 0.8%, and blends allow a lower dose.

Why is phenoxyethanol usually blended with ethylhexylglycerin?

Phenoxyethanol is strong against bacteria but weaker against mould and yeast. Ethylhexylglycerin increases cell membrane permeability and boosts the overall effect, which is the basis of the common 9:1 blend. Pairing with 1,2-hexanediol or pentanediol works the same way.

What pH range does phenoxyethanol work in?

It is stable from pH 3 to 10, a wider range than parabens or organic acid preservatives, which is one reason it became a general-purpose preservative.

How should phenoxyethanol be added during processing?

It is a liquid at room temperature and can be added to the water phase or after emulsification. High temperature increases evaporation loss, so add below 45 °C and mix well.

Where can I confirm the current specification?

This page is a product information note. Assay, packaging and the applicable standard follow the current datasheet from sales, which you can request through the enquiry form.
