Introduction:
Cetomacrogol-1000 (also known as CM-1000 or PEG-1000 Cetostearyl Ether) is a non-ionic emulsifier widely used in cosmetic, pharmaceutical, and personal care formulations. It serves as a stable and effective O/W (oil-in-water) emulsifying agent, enabling the creation of smooth, consistent creams, lotions, and ointments. Its compatibility with a wide range of ingredients and pH levels makes it a go-to emulsifier in both commercial and medicinal skin care products.
What is Cetomacrogol-1000?
Cetomacrogol-1000 is the polyethylene glycol ether of cetostearyl alcohol. It appears as white waxy flakes or pellets and dissolves in hot water to form stable emulsions. Due to its mild nature and excellent emulsifying properties, it is especially suitable for sensitive skin products, including dermatological creams and baby care items.
