It is used in cement suspension, emulsion, injection, etc. It is also used as the base of water-soluble ointment and suppository. The solid waxy PEG with high molecular weight is often used to increase the viscosity and solidness of low molecular weight liquid PEG, as well as to compensate for other drugs. For drugs that are not easy to dissolve in water, this product can be used as a carrier of solid dispersing agent to achieve the purpose of solid dispersing, hydrophilic polishing material, film material and capsule material, plasticizer, lubricant and dropping pill matrix, used for the preparation of tablets, pills, capsules, microcapsules, etc.
