Ngwaahịa cellulose ether HPMC na HEMC nwere ma hydrophobic na hydrophilic otu. Otu methoxy bụ hydrophobic, na otu hydroxypropoxy dị iche dabere na ọnọdụ nnọchi. Ụfọdụ bụ hydrophilic na ụfọdụ bụ hydrophobic. Hydroxyethoxy bụ hydrophilic. Ihe a na-akpọ hydrophilicity pụtara na ọ nwere ihe onwunwe nke ịnọ nso na mmiri; hydrophobicity pụtara na o nwere ihe onwunwe nke ịghaghachi mmiri. Ebe ọ bụ na ngwaahịa ahụ bụ ma hydrophilic na hydrophobic, ngwaahịa cellulose ether nwere ọrụ elu, nke na-emepụta ikuku ikuku. Ọ bụrụ na naanị otu n'ime ihe abụọ ahụ bụ hydrophilic ma ọ bụ hydrophobic, ọ dịghị egosipụta ga-emepụta.
