Description

  The present invention relates to a method for using cosmetics, and more particularly to a method for applying cosmetics.

Skin care cosmetics such as skin lotions, creams, and emulsions are cosmetics that are applied directly to the skin (skin) of the human body. After the skin care cosmetics are applied, makeup cosmetics are applied as necessary.
As such cosmetics, by treating a cosmetic semi-finished product or a finished cosmetic product for a certain period of time with an ultra-high pressure (3,000 kgf / cm ² or more), a “cosmetic that stretches against the skin” ”Smooth and full-bodied feel, low stickiness, and skin-friendly cosmetics” ・ “Moisturizing and moisturizing effect, long-lasting cosmetics and other cosmetic effects”, etc. It has been proposed to promote and improve basic and essential functions and characteristics of cosmetics (see Patent Document 1).
Japanese Patent No. 2969365

However, although the cosmetics described in Patent Document 1 can promote and improve the basic and essential functions and properties of cosmetics, it improves wrinkles, lifts up, and improves transparency. Regarding the effect and hair-growth effect, there is a problem that the immediate effect is insufficient and it is difficult to confirm the effect remarkably.
The object of the present invention is excellent in immediate effect, skin elasticity improvement effect, wrinkle improvement effect, lift-up effect, skin transparency improvement effect, skin moisturizing effect, whitening effect (skin color improvement effect), hair growth effect Use of cosmetics that can significantly confirm hair thickness improvement effect, hair gloss improvement effect, pore improvement effect, skin texture improvement effect, acne improvement effect, and anti-inflammatory effect It is to provide a method.

In order to achieve the above object, the method of using the cosmetic of the present invention is a method in which the cosmetic is subjected to a pressure treatment at 50 to 190 MPa for 15 minutes or more, and the cosmetic after the pressure treatment is applied within 8 hours after the pressure treatment. It is characterized by being applied to the skin or hair.
Moreover, in the usage method of the cosmetics of this invention, it is suitable for the said pressurization process to heat cosmetics to 10-50 degreeC.

  In the method for using the cosmetic of the present invention, first, the cosmetic is pressure-treated at 50 to 190 MPa for 15 minutes or more. Then, the pressure-treated cosmetics improve skin firmness, wrinkle improvement, lift-up effect, skin transparency improvement effect, skin moisturizing effect, whitening effect, hair growth effect, hair shine improvement effect It becomes an active state capable of imparting pore improving effect, skin texture improving effect, acne improving effect, and anti-inflammatory effect.

  In the method of using the cosmetic of the present invention, the cosmetic is then applied to the skin or hair within 8 hours after the pressure treatment. Then, the applied cosmetic penetrates into the skin or hair while maintaining the active state. For this reason, the skin or hair penetrates into the active state of the cosmetics to improve wrinkles, lift-up effect, transparency improvement effect, whitening effect, hair growth effect, anti-inflammatory effect, acne improvement effect, etc. Since these effects appear immediately, these effects can be remarkably confirmed.

In the method of using the cosmetic of the present invention, first, the cosmetic is pressure-treated at 50 to 190 MPa for 15 minutes or more.
In the present invention, the cosmetic does not include a semi-finished cosmetic product, but only a finished cosmetic product after production. That is, the cosmetic of the present invention is not related to the presence or absence of the pressure treatment during the production, and is intended for the pressure treatment of the finished cosmetic product after production.

Such cosmetics include, for example, skin care cosmetics that are applied directly to the skin of a human body (including the face and body) to give the skin a smooth, moist feeling.
Examples of skin care cosmetics include facial cleansing foams, lotions, creams, milky lotions, gels, massages, essences, lotions, packs, sunscreens, shaving lotions, and the like. The cosmetics of the present invention include, for example, hair cosmetics that are applied to hair such as tonics, shampoos, rinses, and hair creams, for example, hair growth agents that are mainly applied to the scalp for the purpose of preventing hair loss and promoting hair growth. Also included are hair growth and hair nourishing cosmetics such as hair nourishing agents, for example, hair coloring agents such as hair colors and hair manicures, and cosmetics containing powders such as liquid foundations and cream foundations.

  The cosmetic of the present invention is not particularly limited, and can be appropriately selected from various dosage forms such as liquid, cream, jelly, emulsion, sol and gel. In addition, the cosmetic of the present invention is an average before pressure treatment when the average particle size can be measured, such as powder, slurry, emulsion (including micelles), and dispersion. The particle diameter is preferably 0.1 to 10 μm, more preferably 1 to 5 μm, for example, as a median diameter. The median diameter can be measured by, for example, a laser diffraction / scattering particle size distribution measuring apparatus. The cosmetic of the present invention has a viscosity (26 ° C.) before pressure treatment of, for example, 0.1 to 50 Pa · s (26 ° C.), and further 0.5 to 30 Pa · s (26 ° C.). Preferably it is. The viscosity can be measured with a B-type viscometer (Brookfield viscometer) at 26 ° C.

  In addition, the cosmetic of the present invention preferably contains a high molecular compound capable of imparting elastic force, such as white jellyfish polysaccharide, carboxyvinyl polymer, agar, collagen, and the like. If such a polymer compound is contained, wrinkle improvement and lift-up effect can be further improved. In addition, the mixture ratio of such a high molecular compound is 0.001-1 weight% with respect to the total amount of cosmetics, for example.

  The pressurizing treatment of the cosmetic is not particularly limited, and a known press method such as a direct pressure press method or an isotropic pressure press method can be used according to the dosage form, the treatment amount, and the like. Preferably, an isotropic press method (CIP), more preferably an isostatic press method can be used. When pressure treatment is performed by a CIP method such as a hydrostatic pressure press method, for example, a cosmetic is first enclosed in a flexible bag (such as a heat seal bag), and then a flexible bag in which the cosmetic is enclosed. Is put into a pressure medium tank of a known isotropic press machine (for example, a water tank of an isostatic press machine) and then pressed.

  In the pressure treatment, the cosmetic is applied at 50 to 190 MPa, preferably 70 to 150 MPa, more preferably 85 to 125 MPa, 15 minutes or more, preferably 20 minutes or more, usually 60 minutes or less, for example, 15 to 15 MPa. The pressure is applied for 60 minutes, preferably 20 to 60 minutes, more preferably 25 to 50 minutes, and then returned to normal pressure. When the pressure is less than the lower limit or when the time is shorter than the lower limit, it is difficult to obtain sufficient effects of the present invention on the skin and hair because the average particle size of the cosmetic is too large. It becomes. On the other hand, when the pressure exceeds the above upper limit, the average particle size of the cosmetic (when the average particle size can be measured, the same applies hereinafter) becomes too small. It is difficult to obtain a good effect. Moreover, even if time passes for 60 minutes or more, since an effect is not recognized, 60 minutes is suitable for the upper limit of time from an economical viewpoint.

  In the pressurizing treatment, the cosmetic is preferably heated to 10 to 50 ° C, more preferably 30 to 50 ° C, and particularly preferably 30 to 40 ° C. In the pressure treatment, if the cosmetic is heated in the above temperature range, the immediate effect of the excellent effect of the present invention described later can be improved. In addition, when cosmetics are heated at the temperature exceeding the said upper limit, the state of cosmetics will change and it may become unsuitable for use.

The heating is performed by, for example, installing a heater such as a jacket or a heater on a known press machine (such as the hydrostatic press machine described above) so that the temperature of the cosmetic is in the above temperature range. Set the heating temperature at.
By the pressure treatment as described above, the cosmetic of the present invention has the above-described various effects such as wrinkle improvement, lift-up effect, transparency improvement effect, whitening effect, hair growth effect, anti-inflammatory effect, and acne improvement effect. It will be in the active state which can provide. The active state is a state in which a cluster of water molecules and component particles that have been changed by the pressure treatment can express a self-restoring force to restore the state before the pressure treatment.

  That is, the average particle size and viscosity of the cosmetic after the pressure treatment are reduced with respect to the cosmetic before the pressure treatment. For example, the cosmetic of the present invention can measure the average particle size. In the case of the form, it is a state in which the average particle diameter (median diameter) before the pressure treatment is, for example, 1 to 80% smaller, preferably 10 to 50% smaller. The median diameter is, for example, 0.01 to 10 μm, and further 0.05 to 5 μm. Further, the viscosity (26 ° C.) of the cosmetic after the pressure treatment is, for example, 5 to 50% lower, preferably 10 to 30% lower, and more specifically, for example, 0 5 to 5 Pa · s (26 ° C.), and further 1 to 3 Pa · s (26 ° C.).

  In such a state, the cosmetic of the present invention is gradually restored to the average particle diameter (median diameter) or viscosity before pressure treatment (or its viscosity) immediately after application to the skin and hair by self-restoring force. The state changes as described above) and gives firmness (tension and elasticity) to the skin and hair, thereby improving wrinkles, lift-up effect, transparency improvement effect, whitening effect, hair growth effect, anti-inflammatory effect Various effects described above, such as an acne improvement effect, can be imparted.

Next, in the method for using the cosmetic of the present invention, the cosmetic after pressure treatment is applied to the skin or hair within 8 hours, preferably within 3 hours, more preferably within 1 hour after the pressure treatment. Apply.
If it is not applied within the above time, the active state of the cosmetic of the present invention disappears. In other words, before the cosmetic of the present invention is applied to the skin or hair, the state before the pressure treatment ( Or the active state disappears more than that), and it becomes difficult to obtain the excellent effect of the present invention.

The skin to which the cosmetic is applied is not particularly limited and may be any part of the human skin.
In order to apply the cosmetic of the present invention to the skin, the cosmetic after the pressure treatment may be applied to the skin by a method of normally applying the cosmetic. For example, the cosmetic after the pressure treatment is applied to the skin. Apply directly to. The application amount is not particularly limited, and is about 0.1 to 2 g, for example, although it depends on the size of the face as long as it is for one face.

The hair to which the cosmetic is applied is not particularly limited, but is mainly hair, and in order to apply the cosmetic of the present invention to the hair, the cosmetic after the pressure treatment is usually applied by a method of applying the cosmetic. What is necessary is just to apply | coat to hair, for example, the cosmetics after a pressurizing process are applied directly to hair.
Thus, when the cosmetic is applied to the skin or hair within the above time after the pressure treatment, the cosmetic penetrates into the skin or hair while maintaining the activated state described above, Attempts to restore (or change the state of) the state before the pressure treatment inside the hair. For example, an emulsion in an activated state is in a state where the average particle diameter and viscosity gradually increase. Then, the skin or hair swells due to the self-restoring power of the cosmetic and is given elasticity, and as a result, the effect of improving wrinkles such as stretching of wrinkles, the effect of improving the elasticity of the skin (raising the skin), For example, from lift-up effect, transparency improvement effect that improves skin transparency by improving moisture retention, hair growth effect that promotes hair growth while giving gloss to hair, troubles of rough skin (redness, itching, etc.) after shaving Anti-inflammatory effect that protects skin is expressed.

  Such an effect is expressed immediately after the cosmetic is applied to the skin or hair, and after the cosmetic is maintained for a certain period of time in the active state described above, the active state of the cosmetic disappears. The above effects also disappear. More specifically, the above-described effect is manifested, for example, within 3 hours immediately after the cosmetic is applied to the skin or hair, and the duration of the effect is, for example, about 2 weeks at the longest.

Hereinafter, although a formulation example, an evaluation test example, etc. are shown and this invention is demonstrated more concretely, this invention is not limited to these description at all.
