Embodiment 1

[0065]Facial wipes were prepared by thermal lamination of the microporous film described above to a 30 g / m2 polypropylene meltblown microfiber nonwoven. Can be according to U.S. Pat. The melt-blown hydrophilic fabrics used in the present invention were prepared as described in . In particular, as in Wente's "Superfine Thermoplastic Fibers", "Superfine Thermoplastic Fibers" 48 INDUS.ENG'G CHEM.1342 (1956) "Industrial Engineering Chemistry" Vol. 48, p1342 (1956) or The method described in Wente et al.'s "Manufacture of Superfine Organic Fibers" (MANUFACTURE OF SUPERFINE ORGANIC FIBERS "Navy Research Laboratory" No. 4364 report) (Naval Research Laboratories No.4364, 1954) can be used to prepare this Invented non-woven fabrics. However, since the surfactants used as melt additives in the present invention may be thermally unstable, it is preferable to add the surfactants to the polymer melt just before it is extruded from the die, as described in U.S. Patent No. 4,933,229 (Insl...

Embodiment 2

[0067] Facial wipes were made by heat laminating the microporous film described above to a 34 g / m 2 spun nonwoven made of 70% rayon fiber and 30% polypropylene fibers. The nonwoven side of the laminate was impregnated with a water / ethanol (15%) mixture by spray coating. The microporous film was laminated to the nonwoven using a 5% circular, point-bonded emboss at 66°C and a nip pressure of 3.5 kg / cm2. The resulting laminate is capable of functioning as an oil and sweat wet facial wipe where the user can use the microporous film side to degrease the skin and turn the wipe over to use the nonwoven side to wipe off sweat and dirt. The nonwoven fabric can be loaded with dry or wet fragrances, cleansers, sensates, actives, etc. for added functionality.

Embodiment 3

[0069] Facial wipes were made according to Example 1 using the following dry ingredients at 9% solids in isopropanol:

[0070] 34.06% Sericite TKC (potassium aluminum silicate)

[0071] 17.03% Talc JA-46R (hydrous magnesium silicate)

[0072] 8.55% Urethane D-400 Powder (Hexamethylene Diisocyanate / Trimethylol Caprolactone)

[0073] 0.20% red Tarox iron oxide pigment

[0074] 0.40% Yellow Tarox Iron Oxide Pigment

[0075] 0.02% Black Tarox Iron Oxide Pigment

[0076] 39.74% Rheodole Super SP-L10 (Sorbitan monolauryl)

[0077] The coated microporous membranes were allowed to air dry for 24 hours prior to testing. The dry powder weight on the film was 2.50 g / m2. The resulting wipe can be used to absorb sebum and provide a powder to the skin to remove shine. Powders can be formulated to provide additional cosmetic and active ingredients, including sebum absorption or control agents.

Abstract

There is provided a package 40 of multiple oil absorbing wipes 44 suitable for wiping a users skin or hair. The invention wipes comprise an oil absorbing porous film of a thermoplastic material having a transparency of less than 65 which porous substrate changes transparency when loaded with oil. The porous substrate has directly on one face an oil contaminable layer, without any intermediate oil impermeable layer or film. The porous film has a percent oil retention of from 50 to 100 percent.

Description

Background of the invention [0001] The present invention relates to oil-absorbing skin wipe products. In particular, the present invention relates to dispensable packaged oil-absorbing skin wipe products. [0002] The skin on the face, especially the nose, cheeks, and forehead is constantly oozing a lot of oil. Removal of excess surface oil or sebum is important in order to maintain cleanliness, remove shine, and improve the spreadability of cosmetic and other skin care products. Soap and water can do the trick to a certain extent, but there are always situations where you can't wash your face. Dry methods of removing these facial oils involve using thin, oil-absorbing wipes. Oil-absorbing wipes for removing facial oils have also been disclosed in the prior art. These wipes generally must be thin, comfortable, and non-abrasive, considerations that are not relevant to industrial absorbent materials. [0003] Conventional paper wipes are used to remove facial oils. For exa...
