Description

Sheet-like cosmetics {SHEET-LIKE COSMETIC}

This invention relates to the wet type sheet-like cosmetics of non-alcohol which is excellent in usability and can ensure low stimulation property and low temperature stability while maintaining antiseptic performance. .

When the aqueous solution containing an antimicrobial antiseptic agent is impregnated in paper or a nonwoven fabric, the antimicrobial antiseptic agent is mostly adsorb | sucked to a fiber. Specifically, about 80% of N- palm oil fatty acid acyl L-arginine ethyl DL pyrrolidone carbonate and about 30% of paraoxybenzoic acid esters (parabens) are adsorbed. Is significantly lowered.

Therefore, a large amount of antimicrobial antiseptics are compounded in the lean composition impregnated with a wet sheet, a wet wiper, a wet cotton, etc. in anticipation of the powder adsorbed to a fiber (refer patent document 1).

In addition, parabens generally used as antifungal agents have skin irritation and estrogen bioactivity, and thus risk of breast cancer and effects on reproductive tissues are problematic. It is becoming. In order to reduce the content of such parabens, for example, combining a paraben with 1,2-pentanediol or the like has been proposed (see Patent Document 2). Moreover, using together paraben and phenoxy ethanol and thujic acid is proposed (refer patent document 3). According to these proposals, hypoallergenic properties can be ensured, but the antiseptic performance is not sufficient yet, and the present condition is that further improvement and development are desired.

(Sheet-like cosmetic)

The sheet-like cosmetic of the present invention is formed by impregnating a liquid composition on a nonwoven fabric.

The nonwoven fabric is composed of hydrophilic fibers and hydrophobic fibers.

The mass ratio (hydrophilic fiber / hydrophobic fiber) of the said hydrophilic fiber and the said hydrophobic fiber is 90/10-50/50, and 80/20-70/30 is preferable for a feeling of wiping off and a touch. When the said hydrophilic fiber exceeds 90 mass%, the wiping feeling is inferior, it is easy to produce entanglement and tingling at the time of use, and a feeling of stickiness to skin is large. On the other hand, if the said hydrophilic fiber is less than 50 mass%, a touch will worsen by the impregnation of a liquid composition. When the mass ratio (hydrophilic fiber / hydrophobic fiber) of the hydrophilic fiber and the hydrophobic fiber is within the above preferred range, there is no entanglement or dulling at the time of use, no stickiness to the skin, and the liquid composition is more sufficiently Since it can be impregnated, it is advantageous at the point which is more excellent in the moist feeling and the feeling of wiping off when skin is wiped off.

There is no restriction | limiting in particular as said hydrophilic fiber, According to the objective, it can select suitably, For example, natural cellulose fiber, such as cotton, pulp, hemp, viscose rayon obtained from pulp, copper ammonium rayon And regenerated cellulose fibers such as lyocellulose and tencel, which are solvent-spun ray, and regenerated fibers such as chitin, alginic acid fibers, and collagen fibers. Among them, regenerated cellulose fibers are particularly preferable in terms of wiping feeling and usability.

There is no restriction | limiting in particular as said hydrophobic fiber, According to the objective, it can select suitably, For example, polyester fiber, such as polyolefin fiber, such as polyethylene (PE) and polypropylene (PP), polyethylene terephthalate, nylon And synthetic fibers such as polyamide fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, and polyurethane fibers. Among these, polyolefin type fiber and polyester type fiber are especially preferable at the point which has little entanglement and the lumpiness.

Among these, as said hydrophobic fiber, it is especially preferable that it is a heat meltable fiber.

There is no restriction | limiting in particular if it is a fiber which melts by heating and expresses mutual adhesiveness as said heat meltable fiber, According to the objective, it can select suitably, For example, Polyolefin, such as polyethylene, a polypropylene, polyvinyl alcohol, etc. The epidermal part consisting of a single fiber, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, polyethylene terephthalate / ethylene-propylene copolymer, low melting polyester-polyester, etc. has a relatively low melting point. Particular composite fiber, polyethylene terephthal, which is exposed to the surface of a part of each component consisting of a deep core composite fiber, side by side composite fiber, polyethylene terephthalate / polypropylene, polyethylene terephthalate / nylon, polypropylene / polyethylene Sites / ethylene-type conjugated fiber may be used, such as ten minutes to be separated by the components of the heat shrinkage of the one made of a propylene copolymer.

If the basis weight is less than 30 g / m 2, sufficient thickness cannot be obtained, so that the usability may be degraded, such as being torn or entangled at the time of use. It may be disadvantageous in terms of. On the other hand, since the said basis weight becomes a desired thickness as it is in the said more preferable range, it is excellent in usability more and is also advantageous in the point of portability and costability.

There is no restriction | limiting in particular in the thickness of the said nonwoven fabric, Although it can select suitably according to the objective, 0.3 mm-5 mm are preferable and 0.4 mm-2 mm are more preferable. When the said thickness is less than 0.3 mm, it will become round at the time of use, and it will be difficult to use, and when it exceeds 5 mm, it will be reversely too thick and difficult to use.
