摘要:
A system may include an article, and the article may include a membrane having pores and a surfactant in contact with the membrane. The surfactant may function as a super-spreader when in solution. The article may wet out the pores in response to contact with a fluid.

An article includes a membrane having pores extending therethrough, and a surfactant in contact with a surface of the membrane. The surfactant may function as a superspreader when in solution. The membrane surface may wet in response to contact with a fluid. An associated method is provided.
摘要:
Three types of trisiloxane surfactants having the basic formula: MDM′are described wherein the substituents on the differing M and M′ groups, in conjunction with pendant polyalkylene oxide substituents on the D group render the surfactant resistant to hydrolysis under either basic or acidic conditions outside the pH range of 6.0 to 7.5. The compositions are useful in agricultural, household and cosmetic applications.
摘要:
Disiloxane compounds of the formula MM′Where M comprises either branched allyl hydrocarbon substituents or silanyl substituents and M comprises an alkylpolyalkyleneoxide substituent The disiloxane compounds of the invention exhibit an enhanced resistance to hydrolysis outside a pH range ranging from 6 to 7.5, and are useful as surfactants.
