Abstract
The purpose of the present invention is to provide an oil-in-oil type cosmetic which has further improved transfer resistance, has excellent transfer resistance to a substrate having a non-smooth surface such as paper or cloth, and has excellent gloss and stability after application. The present invention relates to an oil-in-oil type liquid cosmetic characterized by comprising: (a) a non-volatile hydrocarbon oil; (b) a non-volatile silicone oil; and (c) a wax compatible with the (b) nonvolatile silicone oil, and does not contain a volatile cyclic silicone oil, wherein the oil-in-oil type liquid cosmetic is formed of an oil-in-oil type emulsion in which the (b) nonvolatile silicone oil forms an external phase (continuous phase) and the (a) nonvolatile hydrocarbon oil forms an internal phase (dispersed phase), and the ratio (mass ratio) of the blending amount of the (a) nonvolatile hydrocarbon oil to the total blending amount of the (b) nonvolatile silicone oil and the (a) nonvolatile hydrocarbon oil is (a)/[ (a) + (b) ]=0.1 to 0.3.
Description
Technical Field
The present invention relates to an oil-in-oil type cosmetic having excellent transfer resistance. More particularly, the present invention relates to a liquid (non-solid) oil-in-oil type emulsified cosmetic composition which does not cause color transfer to a substrate having a non-smooth surface such as paper or nonwoven fabric, and which does not lose gloss and does not make up.
Background
In a makeup cosmetic such as lipstick, the transfer secondary adhesion caused by the contact of the applied cosmetic with a cup or the like is a problem. Conventionally, makeup cosmetics having so-called transfer resistance (effect of no secondary adhesion) which hardly causes secondary adhesion have been studied.
For example, patent document 1 describes that: the stable oil-in-oil type cosmetic excellent in transfer resistance is obtained by containing 5 to 80 mass% of (a) a nonvolatile hydrocarbon oil and 1 to 70 mass% of (b) a nonvolatile silicone oil (methylphenyl polysiloxane) which are difficult to be compatible with each other, further containing 0.1 to 10 mass% of a dextrin fatty acid ester, and adjusting the blending ratio [ a/(a+b) ] of (a) to (b) to 0.4 to 0.8.
The oil-in-oil type cosmetic described in patent document 1 is in an emulsified form in which (a) the nonvolatile hydrocarbon oil is separated into a continuous phase (external phase) and (b) the nonvolatile silicone oil is separated into a dispersed phase (internal phase) (paragraph 0009). By coating, silicone oil of the internal phase oozes out to the surface layer and covers the adhesion layer containing the non-volatile hydrocarbon oil component of the coloring material, thereby exhibiting transfer resistance.
However, in the cosmetic of patent document 1, the color transfer to a substrate having a smooth surface such as Tao Ciqi or glass can be satisfactorily suppressed, but the color transfer may occur to a substrate having a surface with irregularities such as a cup made of paper or a nonwoven fabric mask. Infection with recent new coronavirus infection (covd-19) has been expanding, and wearing masks when going out and when meeting with humans is becoming a new daily routine (new normalcy or new standard). Therefore, there is a need for make-up cosmetics such as lipsticks that do not undergo color transfer even when worn on a mask.

Disclosure of Invention
Problems to be solved by the invention
The present invention has an object to provide an oil-in-oil type cosmetic which is further improved in transfer resistance, has excellent transfer resistance to a substrate having a non-smooth surface such as paper or cloth, and is excellent in gloss and stability after application.
Solution for solving the problem
The present inventors have conducted intensive studies and as a result found that: the present invention has been completed by providing a stable and glossy oil-in-oil type cosmetic composition which can improve transfer resistance on a non-smooth substrate by thickening a non-volatile hydrocarbon oil as an internal phase (dispersed phase) and a non-volatile silicone oil as an external phase (continuous phase) and by using a wax.
Namely, the present invention provides an oil-in-oil type liquid cosmetic comprising:
(a) A non-volatile hydrocarbon oil;
(b) A non-volatile silicone oil; and
(c) A wax compatible with the aforementioned (b) nonvolatile silicone oil,
does not contain volatile cyclic silicone oil,
the oil-in-oil type liquid cosmetic is formed of an oil-in-oil type emulsion in which the (b) nonvolatile silicone oil forms an external phase (continuous phase) and the (a) nonvolatile hydrocarbon oil forms an internal phase (dispersed phase),
(a) The ratio (mass ratio) of the amount of the nonvolatile hydrocarbon oil to the total amount of the nonvolatile silicone oil (b) and the nonvolatile hydrocarbon oil (a) is (a)/([ (a) + (b) ]=0.1 to 0.3.
ADVANTAGEOUS EFFECTS OF INVENTION
The oil-in-oil type liquid cosmetic of the present invention is excellent in transfer resistance after application and does not cause color transfer even to a non-smooth substrate such as paper or cloth. The oil-in-oil type liquid cosmetic of the present invention has gloss, good spreading at the time of application, and excellent stability.
Detailed Description
The oil-in-oil type liquid cosmetic (hereinafter also simply referred to as "cosmetic") of the present invention contains (a) a nonvolatile hydrocarbon oil, (b) a nonvolatile silicone oil, and (c) a wax as essential components.
(a) A non-volatile hydrocarbon oil,
The nonvolatile hydrocarbon oil (a) used in the present invention is preferably selected from hydrocarbon oils which are separated at 25 ℃ when mixed with the nonvolatile silicone oil (b) described later and have a viscosity higher than that of the nonvolatile silicone oil (b). Further, the non-volatile hydrocarbon oil (a) is more preferably selected from hydrocarbon oils which are homogeneously dispersed at 90 ℃ when mixed with the non-volatile silicone oil (b).
Specific examples of the nonvolatile hydrocarbon oil (a) in the present invention include hydrogenated polyisobutylene, polybutene, polyisoprene, liquid paraffin, squalane, hydrogenated polydecene, and vaseline. (a) The nonvolatile hydrocarbon oil may be a mixture of 1 or 2 or more. Of the foregoing examples, hydrogenated polyisobutene (average molecular weight=1000 to 3000) is particularly preferably used.
(a) The amount of the nonvolatile hydrocarbon oil is 5 to 35% by mass, preferably 10 to 30% by mass. (a) When the blending amount of the nonvolatile hydrocarbon oil is too small, the amount of the coloring material that can be blended is limited, and when the blending amount of the nonvolatile hydrocarbon oil is too large, (a) the sticky feeling is increased, and the transfer resistance tends to be lowered.
(b) Non-volatile silicone oil
As the (b) nonvolatile silicone oil, as described above, it is preferably selected from silicone oils which separate at 25 ℃ when mixed with (a) nonvolatile hydrocarbon oil and have a viscosity lower than that of (a) nonvolatile hydrocarbon oil. Here, the presence or absence of "separation" was measured under the following conditions.
(measurement conditions)
And (a): (b) =1: 1 (mass ratio) using (a) and (b), heating to 90 ℃ to stir and mix, then standing, and when the mixture became 25 ℃, uniformly separating the boundary into 2 layers as "separation occurred", and a translucent state or a transparent compatible state without boundary as "no separation occurred".
Specific examples of the (b) nonvolatile silicone oil in the present invention include methylphenyl polysiloxane, polydimethylsiloxane, fluorine-modified alkyl silicone, and the like. Among these, methylphenyl polysiloxanes are preferred, and particularly preferred are methylphenyl polysiloxanes having a viscosity of 300 to 500 cs.
(b) The amount of the nonvolatile silicone oil is 60 to 90% by mass, preferably 70 to 80% by mass. When the blending amount of the nonvolatile silicone oil is too small, transfer resistance tends to be lowered, and when the blending amount is too large, gloss is increased but color development sometimes lowers.
(c) Wax
The wax (c) to be incorporated in the cosmetic of the present invention may be any wax compatible with the nonvolatile silicone oil (b).
Specific examples of the wax preferably used in the present invention include at least 1 kind selected from the group consisting of beeswax, candelilla wax, sucrose tetrastearate triacetate (Sugar wax), carnauba wax, C30-45 alkyl polymethylsiloxane/C30-45 olefins (Silicone wax), microcrystalline wax/paraffin wax (Paramix), microcrystalline wax/polyethylene (PA wax) and Rice husk wax (Rice wax).
In the above specific examples, from the viewpoint of stability of the oil-in-oil emulsion, at least 1 wax selected from the group consisting of beeswax, candelilla wax, sucrose tetrastearate triacetate (Sugar wax), carnauba wax and C30-45 alkyl polymethylsiloxane/C30-45 olefin (Silicone wax) is preferably used.
The amount of the wax (c) contained in the cosmetic of the present invention is an amount in which the cosmetic becomes "liquid". Specifically, it is usually 1 to 6% by mass, preferably 1.5 to 5% by mass, more preferably 2 to 4% by mass, and may be 3% by mass or less. When the amount of wax blended is too small, the oil-in-oil type emulsified cosmetic may not be stable, and when the amount is too large, the hardness becomes high and the spreading at the time of application becomes poor.
The cosmetic of the present invention does not contain volatile cyclic silicone oils. If volatile cyclic silicone oils are blended, the blending components tend to separate, and it is difficult to prepare stable cosmetics. Volatile cyclic silicone oils refer to: examples of the cyclic silicone oil which exhibits volatility at normal temperature and pressure include cyclic silicone oils such as decamethyl cyclopentasiloxane, octamethyl cyclotetrasiloxane, and dodecamethyl cyclohexasiloxane.
On the other hand, "nonvolatile" in the present specification is a meaning that no volatility is shown at normal temperature and pressure. The evaporation rate at normal temperature and pressure can be lower than 0.01mg/cm for convenience 2 The oil per minute is defined as a nonvolatile oil, and is not particularly limited.
In the cosmetic of the present invention, the blending ratio (mass ratio) of (a) the nonvolatile hydrocarbon oil and (b) the nonvolatile silicone oil is (a)/([ (a) + (b) ]=0.1 to 0.3, and an oil-in-oil emulsion is formed in which (b) the nonvolatile silicone oil forms the external phase (continuous phase) and (a) the nonvolatile hydrocarbon oil forms the internal phase (dispersed phase). Further, by blending (c) a wax in an appropriate amount, the external phase (continuous phase) is thickened, whereby a stable, liquid oil-in-oil type cosmetic (liquid cosmetic) excellent in transfer resistance is formed.
The term "liquid cosmetic" in the present invention means: soft pasty or viscous liquid cosmetics, which can be filled in flat (shallow) containers such as bottles, tubes or jars, are distinguished from "solid" or "stick-like" cosmetics. That is, "liquid" according to the present invention may be said to be "non-solid (or non-rod)". Specifically, a cosmetic having a hardness (25 ℃) of 300gf or less, preferably 200gf or less, as measured by a durometer (using an 11.3 phi needle), or a cosmetic having a viscosity (30 ℃) within a range of 1 to 1000 Pa.s, as measured by a B-type viscometer, can be defined as a "liquid cosmetic" according to the present invention.
In the cosmetic of the present invention, the (d) dextrin fatty acid ester is preferably further blended as the case may be.
In particular, when microcrystalline wax, microcrystalline wax/paraffin wax (Paramix), microcrystalline wax/polyethylene (PA wax), or Rice bran wax (Rice wax) is used as the wax (C), the dextrin fatty acid ester (d) is allowed to coexist from the viewpoint of stability.
(d) The dextrin fatty acid ester is an ester of dextrin and a higher fatty acid having 12 to 22 carbon atoms. The dextrin fatty acid ester (d) of the present invention may be a fatty acid in which a part of the higher fatty acid ester is replaced with a fatty acid having 6 to 10 carbon atoms. Examples of the dextrin fatty acid ester include dextrin palmitate, dextrin myristate, and dextrin palmitate/ethylhexanoate, and trade names of the dextrin fatty acid ester are used as commercial products: rheopearl KL, rheopearl KL2, rheopearl TT2, rheopearl MKL2 (all manufactured by Qianlike mill Co.) and the like.
(d) The amount of the dextrin fatty acid ester to be blended is preferably 0.1 to 10% by mass, more preferably 0.5 to 8% by mass. (d) The blending of the components contributes to stabilization of the system, but when the blending amount is too large, the system becomes sticky.
In the case of adding the dextrin fatty acid ester (d) to the cosmetic of the present invention, it is preferable to add an oil component ("(e)" that dissolves the component (d)).
The component (e) may be an oil component capable of dissolving the dextrin fatty acid ester. For example, polar oils such as ester oil are preferably used, and polyglyceryl-2 isostearate, phytosterol isostearyl dimer linoleate, phytosterol/octyldodecanol lauroyl glutamate, polyglyceryl-2 diisostearate, polyglyceryl-2 triisostearate, and the like are particularly preferably used.
The cosmetic of the present invention preferably further comprises (f) anhydrous silicic acid. By compounding (f) anhydrous silicic acid, stability is further improved. As the anhydrous silicic acid (f), ultrafine anhydrous silicic acid having an average primary particle diameter of 1 to 50nm is preferable, and examples thereof include AEROSIL 200, 300, R972, R974, RY200 and the like (manufactured by AEROSIL Co., ltd.). The anhydrous silicic acid used in the present invention may be hydrophilic or may be subjected to a hydrophobic treatment such as silylation.
(f) The content of the anhydrous silicic acid is 0.5 to 5% by mass, preferably 1 to 4% by mass.
The cosmetic of the present invention preferably further contains (g) a coloring material. (g) The coloring material may be any coloring material commonly used in make-up cosmetics such as lipsticks, and may be in the form of powder or a lake (in the state of oil kneaded). The coloring material, whether it is an inorganic pigment, an organic pigment or a pearlescent agent, is more wettable to (a) a nonvolatile hydrocarbon oil than (b) a nonvolatile silicone oil and is eventually transferred to a spontaneous dispersion layer, i.e., (a) a nonvolatile hydrocarbon oil (internal phase).
The amount of the coloring material (g) is 0.01 to 30% by mass, preferably 0.1 to 20% by mass.
In addition to the above, the cosmetic of the present invention may be suitably blended with oils, powders, dyes, polymer compounds, moisturizers, fragrances, surfactants, antioxidants, preservatives, cosmetic ingredients, and the like, which are generally used in oily cosmetics, particularly in make-up cosmetics such as lipsticks, within a range that does not impair the effects of the present invention. Examples of the humectant include polyhydric alcohol-based humectants such as glycerin, propylene glycol, and 1, 3-butanediol.
The cosmetic of the present invention includes the case where the glyceryl behenate/eicosadioate is not contained. When the glyceryl behenate/eicosadioate is contained, the blending amount is preferably less than 0.1 mass%.
The cosmetic of the present invention can be applied to liquid lipsticks, lip colors, lip soles for make-up, lipstick, etc. In particular, when the pigment is used in a lipstick containing a coloring material, the pigment is suitable because it can provide both the color development effect and the transfer resistance, and gloss such as lip gloss.
