The invention relates to a hydrophilic cotton pad for skin-care exhibiting a specific surface weight of at least 150 g/m2, and having two different outer sides of which the fibers are entangled. In the invention, the first outer side has hollow striae apart by a spacing s1 between 1 and 8 mm and having a depth d of at least 0.25 mm and wherein at least 50% of the fibers are entangled. The pad of the invention is used to apply skin-care products, such as cosmetics, to the skin.
A hydrophilic cotton pad used for skin-care having a specific surface weight of at least 150 g/m2, comprising a first outer side and a second outer side which are different from each other and which each have fibers which are entangled, wherein the first outer side comprises hollow striae spaced apart by a spacing s1 of between 1 and 8 mm and have a stria depth d of at least 0.25 mm, and wherein the pad has a tensile strength of at least 20 N in a direction of motion and at least 16 N in a direction transverse thereto.

The present invention relates to a hydrophilic, skin-care cotton pad exhibiting a minimum specific surface weight of 150 g/m2 and having two different outer sides.
Hereafter, the expression “hydrophilic cotton pad” encompasses any product cut into a given format and substantially containing cotton fibers in a proportion of 70 to 100% and synthetic fibers in a proportion of 0 to 30%. Illustratively, the latter fibers are polyolefin-based heat-melting fibers.
Skin-care includes body care, face care, and in particular, care involving cosmetics, namely face make-up and make-up removal, baby care, namely washing and changing the infant, and the like.
Other features and advantages of the invention are elucidated in the description below and in relation to the attached drawings.
FIG. 1 is a perspective of a pad of the invention,
FIG. 2 is a schematic cross-section along line II—II of the pad shown in FIG. 1,
The pad of the invention is a round, oval, square cutout, or any other shape. Its specific surface weight is between 150 and 400 g/m2, preferably between 180 and 300 g/m2. It is based on cotton and essentially comprises absorbing hydrophilic cotton fibers. More specifically, it contains 70 to 100% homogeneous cotton fibers and 0 to 30% artificial fibers such as those of viscose, of synthetic fibers such as of polyester, binary fibers (polyester/polyester, polypropylene/polypropylene or polyester/polypropylene), or mixtures thereof.
The pad comprises one lap composed of one or more layer(s) constituted of cotton fibers. The pad also can comprise two superposed layers each constituted of a cotton lap. The pad also can comprise three layers, a central one of a lap of cotton fibers and two outer ones, illustratively, of cotton webs and enclosing the central layer.
In the pad's embodiments shown in FIGS. 1 through 3B, the pad 1 comprises a first outer side 2, 2′ and a second outer side 3, 3′. The first outer side 2, 2′ comprises striae 4, 4′; 5, 5′ and 6, 6′ which in this instance run parallel to each other. The spacings s1 between the striae is between 1 and 8 mm, preferably between 1.2 and 5.5 mm and in particular between 2 and 4 mm. The stria depth d is at least 0.25 mm, preferably at least 0.50 mm. The striae subtend troughs 7, 7′ and peaks 8, 8′ which are visible to the naked eye. The second outer side 3, 3′ also is fitted with striae 9 and 10 which are much finer and closer to each other. The spacing s2 between the striae of this second surface is between 0.4 and 1.2 mm.
