Abstract:
There is provided an oil absorbing wipe material suitable for wiping a users' skin or hair and a method for their manufacture. The wipes comprise at least an oil absorbing porous film-like substrate of a thermoplastic material. Generally, the wipe changes transparency or color (a change in L* of about 10 or more) when loaded with oil to provide an oil absorption indication functionality. The wipe is formed by (a) providing a porous film-like substrate of a thermoplastic material capable of absorbing facial or body oils and changing transparency or color, and (b) coating the porous substrate with oil, either continuously or in regions, wherein the oil coating is not sufficient to change the transparency or color of the substrate such that it loses its oil absorption indication functionality. This oil coating being of a nature such that the coated porous substrate has an increased oil absorption indicating functionality.
