Abstract

PURPOSE:To obtain an oily solid cosmetic having soft touch and high spreadability and giving excellent luster and durable make-up by compounding a specific amount of an oil-soluble resin to an oily solid cosmetic containing an oil, a wax and a powder. CONSTITUTION:The objective oily solid cosmetic is produced by compounding 0.1-25wt.% (preferably 2.0-20wt.%) of an oil-soluble resin [e.g. ESCOREZ-1102,1202, etc., (aliphatic hydrocarbon produced by Tonex Inc.) or ESCOREZ-1401 (an aliphatic/alicyclic hydrocarbon)] to an oily solid cosmetic containing an oil component such as liquid paraffin, squalane and olive oil, a wax such as polyethylene, solid paraffin, vaseline and candelilla wax and powder such as talc, mica, kaolin and titanium oxide. The cosmetic is an epoch- making one satisfying various requirements for solid O/W-type emulsion cosmetic.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new solid oil-based cosmetic, and more particularly to a solid oil-based cosmetic that is soft to the touch, spreads well, has a glossy shine, and has excellent makeup retention.

0002

BACKGROUND OF THE INVENTION Solid oil-based cosmetics are mainly composed of oils, waxes, powders, etc., and much research has been conducted to obtain desired usage characteristics by adjusting the types and amounts of each. It is widely used for its unique properties such as lightness of spread, gloss, and fit. However, as can be seen with lipsticks, it is a well-known fact that there are limits to the usage characteristics of oil, wax, and powder-based solid oil-based cosmetics, and it is difficult to clearly differentiate them. In particular, those that stretch lightly tend to have a poor fit or lose their luster.

0003

[Problems to be Solved by the Invention] In order to improve these drawbacks, as a result of extensive research, we have found that 0.1 to 2.
We have found that a solid oil-based cosmetic containing 5% by weight has a soft touch, spreads well, has a glossy shine, and has excellent makeup retention, and based on this knowledge, we have completed the present invention.

0004

[Means for solving the problems] That is, the present invention contains oil, wax, and powder, and has an oil-soluble resin of 0.1
It relates to a solid oil-based cosmetic characterized by containing ~25% by weight.

The configuration of the present invention will be explained below. The solid oil-based cosmetic of the present invention has no fluidity in the temperature range (0 to 50° C.) normally used as a cosmetic and is solidified (including paste-like). The oils used in the present invention include those commonly used in cosmetics with high skin safety, such as liquid paraffin, squalane,
Castor oil, olive oil, jojoba oil, glyceryl diisostearate, glyceryl triisostearate, trimethylolpropane tri-2-ethyl isostearate,
Glyceryl tri-2-ethylhexanoate, isopropyl myristate, cetyl-2-ethylhexanoate, glyceryl triisostearate, 2-heptyl undecyl palmitate, methylpolysiloxane, methylphenylpolysiloxane, polybutene, diiso Examples include stearyl malate and lanolin, and one or more of these may be arbitrarily selected. The content of these oils in the solid oily cosmetic of the present invention is 35 to 90% by weight, preferably 45 to 75% by weight. If it is less than 35% by weight, the makeup will last well, but it will lack a soft feel and will have poor spreadability. On the other hand, if it exceeds 90% by weight, it will be soft to the touch and spread easily, but makeup will not last long and will have an oily finish.

[0006] The waxes used in the present invention are those commonly used in cosmetics, such as polyethylene wax, ceresin, solid paraffin, microcrystalline wax, vaseline, beeswax, carnauba wax, and candelilla wax. One or more of these can be arbitrarily selected. The content of these waxes is generally 5 to 40% by weight, and if it is less than 5% by weight, it will not be possible to obtain an appropriate hardness, and in the case of stick-shaped cosmetics, it will lead to bending, and although it spreads easily, makeup will not last long. There are disadvantages such as deterioration. When it is 40% by weight or more, the elongation is heavy and the feeling is sticky.

[0007] Powders include talc, mica, kaolin, titanium dioxide, titanium-mica pearl agents, synthetic resin powders such as nylon powder, tikkaboron, and powders obtained by hydrophobizing these powders with silicone fatty acid esters, etc. can be mentioned. One or more types are arbitrarily selected from these. The blending amount is generally 0.5~
It is 70% by weight.

[0008] The resin used in the solid oil-based cosmetic of the present invention is, for example, ESCOREZ-1 manufactured by Tonex Co., Ltd.
102, 1202, 1271, 1291, 1205, 1
304, 1305, 1310, 1311, 1315, 1
Aliphatic hydrocarbons represented by 395, ESCOREZ
-1401 aliphatic/alicyclic hydrocarbon, ESCO
Aliphatic/such as REZ-2101, 2203, 2520
Aromatic hydrocarbons, ESCOREZ-4401 modified aliphatic/aromatic hydrocarbons, ESCOREZ-5380,
Hydrogenated alicyclic hydrocarbons represented by 5300 and 5320, alicyclic hydrocarbons such as ESCOREZ-8180,
Examples include alicyclic hydrocarbons such as ESCOPOL-8030. One or more types are arbitrarily selected from these. The blending amount is 0.1 to 25% by weight, preferably 2.0 to 20% by weight. At 0.1% by weight or less,
If the amount is 25% by weight or more, it is excellent in gloss and makeup retention, but it is undesirable because it has poor spreadability.

[0009] In addition to the above-mentioned essential ingredients, the solid oil-based cosmetic of the present invention may contain surfactants, humectants, antioxidants, ultraviolet absorbers, dyes, fragrances, etc., as necessary. Of course, these must be used under qualitative and quantitative conditions that do not impair the effects of the present invention.

As can be seen from Table 1, in Comparative Example 1, the touch to the skin, spreadability, and gloss were somewhat good, but the makeup retention was poor. Example 1 is excellent in all aspects such as touch on the skin, spreadability, gloss, and makeup retention, and has been highly evaluated as a lipstick.

Comparative Example 2 is a case where the amount of resin is very small.
No major characteristics are observed in terms of gloss, makeup retention, etc. Comparative Example 3 is an example in which the amount of resin is extremely large, and although the gloss and makeup durability are excellent, there are problems in terms of touch to the skin, spreadability, etc. Examples 2 and 3 are excellent in touch to the skin, spreadability, gloss, and makeup retention. As is clear from the above results, it was confirmed that the solid oil-based cosmetic of the present invention is extremely excellent in terms of touch to the skin, spreadability, gloss, and makeup retention.
