Macrogol Cetostearyl Ethers are synthesised by ethoxylation of mainly Cetostearyl Alcohol. The number in the product name indicates the average polymer length in ethylene oxide units. As a general rule of thumb, the higher the ethoxylation grade, the more hydrophilic the Macrogol Cetostearyl Ether.
Macrogol Cetostearyl Ethers are primarily used as emulsifiers in pharmaceutical topical dosages, and can be used for both oil-in-water and water-in-oil formulations. They have good solubilising properties, and can also be used to adjust consistency of semi-solid dosage forms.
