Description

Self-heating non-aqueous cosmetic composition

The present invention relates to a non-aqueous exothermic cosmetic composition that improves the insufficient calorific value and persistence, which is a disadvantage of the conventional exothermic cosmetic, and gives an improved emollient feeling after a washoff.

Around the nose, the ball and the jaw of the skin, a lot of wastes such as sebum and keratin are piled up. In particular, the blackhead in which sebum in the pore is shrunken can be easily seen. It is effective to remove the sebum in the pores by hydrophobic substance as an oil-soluble substance. In order to remove the sebum deeply in the pores, it is effective to open the pores by removing the pores by giving a thermal sensation. In the case of pores, the amount of sebum secretion is large, or as it ages, its size increases, and waste products tend to accumulate. In order to make your skin beautiful and make your pores inconspicuous, your skin needs to be clean.

 To date, conventional exothermic cosmetics that give the skin a warm feeling to remove waste products are largely made of synthetic zeolite, a kind of allimonosilicate mineral, as a pyrogenic material, or glycerin, butylene glycol, polyethylene glycol. And the like using polyols as heat generating raw materials.

For example, Korean Patent Publication No. 2004-0056159 discloses a non-emulsifying pyrogenic cosmetic composition including zeolite as a pyrogenic material. However, in the case of using zeolite, the reaction with water causes heat to be generated within a short period of time, so that it is difficult to expect continuous and high heat effect.

In addition, the Republic of Korea Patent Registration No. 0140292 polyol 5 ~ 80 parts by weight, water-soluble polymer 0.01 ~ 2.0 parts by weight, inorganic powder 0.5 ~ 50 parts by weight, hydrophilic emulsifier 0.01 ~ 7.0 parts by weight, alkali 0.01 ~ 2.5 parts by weight, gypsum 0.01 ~ Disclosed is a exothermic massage pack cosmetic composition consisting of 20.0 parts by weight, 0.01 to 5.0 parts by weight of bamboo salt. However, in the case of using a polyol, when the friction is given by a steady massage or the like, it gives a slight thermal effect.

 As described above, the exothermic cosmetic fever and lasting effect is not enough to provide a continuous sense of heat to the skin, thereby insufficient to remove the waste, such as sebum, keratin.

Korean Patent Publication No. 2006-0059854 is an inorganic chloride, for example, a heating element that adheres to the skin in the form of a sheet containing inorganic chlorides such as sodium chloride, potassium chloride, magnesium chloride, calcium chloride, potassium sulfate, magnesium sulfate, sodium sulfate as a heating material, etc. It is starting. However, when such an inorganic chloride is applied directly to the skin as a form of cosmetic composition, magnesium chloride may cause skin irritation and the reaction with water or oxygen may cause instantaneous exothermic reaction. .

In order to compensate for these disadvantages, it is necessary to develop a exothermic cosmetic composition comprising a new heating element capable of increasing the exothermic and lasting effects.

Republic of Korea Patent Publication No. 2004-0056159 Republic of Korea Patent Registration No. 0140292 Republic of Korea Patent Publication No. 2006-0059854

Thus, the present inventors earnestly researched to improve the insufficient heat and sustainability of the conventional exothermic cosmetics, the anhydrous magnesium sulfate particles that generate heat through the moisture absorption process as a heating material, it is exothermic when coated with silicon oil and silica It was confirmed that the effect and sustainability can be improved, and based on this, the present invention was completed.

Accordingly, the problem to be solved by the present invention is to provide a cosmetic composition that gives an excellent emollient feeling when applied to the skin while having an exothermic effect and its sustainability.

To this end,

Anhydrous magnesium sulfate particle core;

A silica coating layer formed surrounding the core; And

Silicon oil coating layer formed surrounding the silica coating layer

It provides a nonaqueous exothermic cosmetic composition containing exothermic particles comprising a.

In addition, the present invention is an anhydrous magnesium sulfate particle core; A silica coating layer formed surrounding the core; And 20 to 50 wt% of exothermic particles comprising a silicon oil coating layer formed surrounding the silica coating layer. 20 to 60% by weight of emollient; It provides a nonaqueous exothermic cosmetic composition comprising 0.5 to 20% by weight wax and 0.5 to 10% by weight surfactant.

According to the present invention, the feeling of fever and duration can be improved to increase the temperature of the skin for a certain time, thereby eliminating skin wastes such as skin sebum and keratin due to the continuous heating, blood circulation, skin penetration of active ingredients, etc. The effect can be increased.

1 is a cross-sectional view schematically showing a cross section of the exothermic particles according to the present invention.

Hereinafter, the present invention will be described in more detail.

Magnesium sulfate has a property of deliquescent property, which is a property of absorbing the surrounding water. In other words, if there is any water vapor or a little water in the atmosphere, there is a feature that is decomposed while absorbing, heat is generated through this process. In particular, anhydrous magnesium sulfate has good hygroscopicity, so it absorbs the surrounding water well to generate heat, the exothermic reaction is instantaneously terminated during use, so the exothermic duration is very short.

Accordingly, in the present invention, the anhydrous magnesium sulfate was granulated to form a core, and a silicone oil and silica were formed as a coating layer on the surface thereof, thereby delaying contact between the moisture and the anhydrous magnesium sulfate particle to impart continuous warmth to the skin.

1 is a cross-sectional view schematically showing a cross section of the exothermic particles according to the present invention.

Referring to FIG. 1, the nonaqueous exothermic cosmetic composition according to the present invention includes an anhydrous magnesium sulfate particle core 1, a silica coating layer 3 formed thereon, and a silicone oil coating layer 5 formed thereon. Exothermic particles 10.

Since the silicone oil forming the outermost silicone oil coating layer 5 of the exothermic particles 10 exhibits hydrophobicity, it prevents instantaneous contact of moisture with the anhydrous magnesium sulfate particle core at the beginning of cosmetic use, but does not cause an exothermic reaction. As a result, the exothermic duration is delayed by contacting the anhydrous magnesium sulfate particle core 1 in the coating layer with water to generate an exothermic reaction.

As the silicone oil, dimethicone, cyclomethicone, polydimethylsiloxane, methylphenyl polysiloxane, methylcyclopolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, tetradecamethylhexahexasiloxane, octamethyltri One kind selected from the group consisting of siloxanes, and mixtures thereof is used.

In addition, the silica coating layer (3) is used to improve the dispersibility and usability in the application of the exothermic particles 10 to the cosmetic formulation.

Thus, anhydrous magnesium sulfate particles are sequentially formed with a silica and a silicone oil to prevent an instant deliquescent property of the anhydrous magnesium sulfate particle core 1, and in addition to the heating feeling of the exothermic particles, the exothermic excellence in use and durability is excellent. To provide particles.

The method of forming a coating layer on the anhydrous magnesium sulfate particles may be used a wet method and a dry method, which is a general surface treatment method. The wet method can stably perform the surface treatment, but since it uses a liquid state, there is a problem in the surface treatment of the exothermic particles reacting with water, and preferably a dry method is used.

In forming the coating layer, silica and silicone oil are used in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of anhydrous magnesium sulfate. If the amount is less than the above range, the effect of forming the coating layer is insignificant. On the contrary, if the amount exceeds the above range, permeation of moisture is difficult and the heat generation time is delayed.

In the exothermic particles of the present invention, the average particle diameter is preferably adjusted to 0.001 to 1,000 µm, more preferably 10 to 1,000 µm. If the particle diameter is less than the above range, the warmth is instantaneously, whereas if the particle size exceeds the above range, it is difficult to formulate into a cosmetic and there is a problem that the feeling of use decreases.

At this time, the thickness of the silica coating layer and the silicone oil coating layer is preferably 0.0001 to 1,500㎛. If the thickness is less than the above range, it is difficult to obtain the exothermic retardation effect according to the coating. On the contrary, if the thickness is exceeded, the exothermic time is excessively delayed due to difficulty in permeation of moisture.

The exothermic particles may be applied to cosmetics of various formulations, for example, a non-aqueous cosmetic composition, a mask pack, and the like.

Non-aqueous cosmetic composition of the present invention is the above-described exothermic particles; Emollient agents; Waxes and surfactants.

The content of the exothermic particles is preferably used in 20 to 50% by weight. If the content is less than the lower limit, the heat generation is insignificant and the skin temperature rise is less effective. Irritation may occur.

The emollient is added as an oily base and uses a volatile oil and a nonvolatile oil together. Specific examples of such volatile oils include isododecane, C 7-8 isoparaffin, C 8-9 isoparaffin, C 10-11 isoparaffin, C 11-12 isoparaffin, C 11-13 isoparaffin, C 12- 20 isoparaffins, C 13-14 isoparaffins, cyclomethicone, cyclotetrasiloxane, cyclopentasiloxane can be selected from one species.

Non-volatile oils include isononyl isonononate, ethylhexyl isonononate, polyisobutene, lanolin oil, squalane, liquid paraffin, caprylic / capric triglylide, butylene glycol dicaprylate, hexyllau 1 type chosen from the rate, isocetyl myristate, isopropyl myristate, and isopropyl palmitate can be used.

At this time, the amount of the emulsifier is preferably 20 to 60% by weight in the cosmetic composition, if less than the lower limit, there is a problem that the flexible feeling of use falls, there is a disadvantage that the stability of the cosmetic formulation exceeds the upper limit.

The wax is used to impart a solidity to the non-aqueous cosmetic composition. Suitable waxes include plant waxes such as candelilla wax, renuba wax and rice wax, animal waxes such as beeswax and lanolin, mineral wax such as ozokerite and ceresin wax, paraffin wax, microcrystalline wax and polyethylene Petroleum waxes such as waxes, ester waxes that are solid at 25 ° C., and the like, and polyetherine wax is preferred.

It is preferable that 0.5 to 20% by weight of such a wax is used in the cosmetic composition. If the content of the wax is less than the above range, the effect of addition is insignificant, and on the contrary, if the wax exceeds the above range, the applicability is not soft and stiff. Feeling of the back is reduced.

The cosmetic composition of the present invention includes a surfactant to clean the oily component from the skin upon wash-off after use. Such a surfactant is not particularly limited in the present invention, but is typically represented by hydrogenicity lecithin, Sodium Cocoyl Isethionate, Sodium Stearate or Potassium Stearate This is possible.

At this time, the content of the surfactant is preferably in the range of 0.5 to 10% by weight of the total resin composition. If the content of the surfactant is less than the above range, the wash off is not made sufficiently, on the contrary there is a problem that can cause skin irritation if the above range is exceeded.

As described so far, according to the nonaqueous exothermic cosmetic composition of the present invention, the exothermic feeling and duration are improved to continuously give warmth to the skin, thereby removing skin wastes such as skin sebum and keratin, and circulating blood Effects such as skin penetration of the components can be increased.

In addition, by providing an enhanced emollient feeling, the skin can be kept smooth and soft.
