Abstract
The present disclosure relates to personal care products such as diapers, training pants, feminine care articles, incontinence articles, bandages, and the like, that have been treated to enhance liquid intake and distribution performance characteristics and reduce leakage. Advantageously, the treated personal care products described herein not only reduce the viscosity and elasticity of viscoelastic fluids that come in contact with the treated product, but also reduce the fouling effect of such fluids.
Claims10
A personal care product for receiving a fluid having viscoelastic properties, said personal care product comprising a backsheet, an absorbent core, an intact layer, a body contact layer, and a treatment agent, wherein the treatment agent is present on at least one of the intake layer and the absorbent core in an amount of from about 3% (by weight of the treated substrate) to about 12% (by weight of the treated substrate) and wherein the treatment agent is polyethylene glycol 600 monolaurate.
A personal care product for receiving a fluid having viscoelastic properties, said personal care product comprising a backsheet, an absorbent core, an intake layer, a body contact layer, and a treatment agent selected from the group consisting of polyethylene glycol laurates, polyethylene glycol lauryl ethers, and combinations thereof, wherein said treatment agent is capable of reducing the viscosity and elasticity of the fluid and is present on at least one of the intake layer and the absorbent core in an amount of from about 3% (by weight of the treated substrate) to about 12% (by weight of the treated substrate).
A personal care product for receiving a fluid having viscoelastic properties, said personal care product comprising a backsheet, an absorbent core, an intake layer, a body contact layer, and a polyethylene glycol derivative selected from the group consisting of polyethylene glycol lauryl ethers, PEG monooleates, PEG dioleates and PEG 16 octyl phenyl, wherein said polyethylene glycol derivative is capable of reducing the fouling effects of the fluid and is present on at least one of the intake layer and the absorbent core in an amount of from about 3% (by weight of the treated substrate) to about 12% (by weight of the treated substrate).
