Description

Pheromone-containing lip cosmetic composition and manufacturing method thereof

The present invention relates to a lip cosmetic composition containing pheromone and a method for producing the same, and more specifically, to a lip cosmetic composition imparting an attractive fragrance and highly moisturizing properties by adding pheromone, and a method for producing the same.

The skin is a representative organ that performs an essential barrier function to retain body moisture and protect the interior from invasion by external factors, while also exhibiting an immune response.

As people age, their skin loses elasticity and wrinkles increase, and the lips undergo the same change process. However, skin care is usually focused on the facial skin and lip care is often neglected, and there is an urgent need for the development of lip care cosmetics to improve this.

It is known that the lips have a thinner keratin layer than normal skin and have very low natural moisturizing factors and moisture content, so moisture loss from the lip surface is several times faster than from the skin.

The above lip make-up corrects the shape of the lips to balance the upper and lower lips overall, makes the contours of the lips distinct, and uses various shades to make the complexion of the face stand out.

Lip products applied to the lips are divided into lip care products for lip protection and treatment purposes and products for makeup purposes. Products for makeup purposes generally include lip tint, lip gloss, lipstick, and lip liner.

Lipstick is made of a mixture of oily substances such as animal and vegetable waxes and oils, with various nutrients and organic and inorganic pigments evenly dispersed to moisturize and color the lips, making them look beautiful and healthy, and also protecting the skin.

In the past, when the purpose of lipstick was to increase moisturizing properties, petrolatum, lanolin wax, and lanolin derivatives were widely used. In more advanced technologies, various emulsifiers such as glycerin, propylene glycol, and water were added to lipstick to increase moisturizing properties, and products that have achieved partial success in terms of actually increasing moisturizing properties have been introduced.

However, there are some cases where the ingredients included for moisturizing purposes actually have a negative effect on the product. For example, the compatibility between lipstick ingredients is poor, causing oil to separate from the lipstick, the hardness of the stick is reduced due to the addition of water-soluble ingredients, and the risk of skin irritation due to the use of various emulsifiers.

Accordingly, the inventors of the present invention continued to conduct research to manufacture a lip cosmetic composition that can impart an attractive fragrance without irritating the skin and at the same time provide high moisturizing properties, and completed the present invention by adding pheromone to the lip cosmetic composition.

Therefore, the technical problem to be solved in the present invention is to provide a lip cosmetic composition that can impart an attractive fragrance without irritating the skin and at the same time provide high moisturizing properties.

In order to solve the above technical problem, the present invention provides a lip cosmetic composition characterized by containing pheromone as an effective ingredient.

Preferably, the pheromone is characterized by being at least one selected from the group consisting of androstenone, androstenol, androstadienone, and estratetraenol.

Preferably, the pheromone is characterized in that it is included in an amount of 0.1 to 1 part by weight based on 100 parts by weight of the total cosmetic composition.

Preferably, the lip cosmetic composition is characterized in that it is formulated in the form of a lipstick, lip balm, lip cream, lip pencil, liquid rouge or lip gloss.

In order to solve the other technical problems mentioned above, the present invention provides a method for producing a lip cosmetic composition, characterized by comprising the following steps:

(S1) A step of forming a first mixture by mixing and stirring vegetable oil, natural wax, pheromone, and additives at a temperature range of 80°C to 100°C;

(S2) A step of forming a second mixture by adding a mattifying agent to the first mixture and mixing and stirring at a temperature range of 50°C to 80°C;

(S3) a step of mixing and stirring by adding a colorant to the second mixture; and

(S4) A step of manufacturing a lip cosmetic composition by putting the second mixture containing the above colorant into a mold.

In this way, the lip cosmetic composition of the present invention imparts an alluring fragrance, and at the same time, has excellent skin adhesion, spreadability, and coloring power, so that it can be smoothly applied on the lips to exhibit excellent coloring, and exhibits excellent staying power, so that high-quality makeup can be maintained for a long time. In addition, the glossiness of the lips can be increased and an alluring fragrance can be imparted. Therefore, the lip cosmetic composition according to the present invention is expected to be very useful as a lip cosmetic composition because it not only has the effects of moisturizing the skin and increasing glossiness, but also has no cytotoxicity and no skin side effects.

The present invention is described in more detail below.

The present invention provides a lip cosmetic composition characterized by containing pheromone as an active ingredient.

According to the present invention, a lip cosmetic composition can be manufactured which imparts a captivating fragrance and at the same time has excellent skin adhesion, spreadability, and coloring power, so that it can be smoothly applied on the lips to show an excellent coloring color, and has excellent staying power to maintain high-quality makeup for a long period of time. The lip cosmetic composition according to the present invention has the advantage of being highly moisturizing without causing skin irritation.

The pheromone used in the present invention refers to a chemical signal used for communication between animals of the same species, and is an exocrine substance, and there are various types of pheromones that regulate behavior and physiology, such as alarm pheromones, food transport pheromones, and sex pheromones. Some vertebrates and plants communicate using pheromones, and they are mainly detected in the endocrine glands of insects such as bees.

In particular, androstenol has been reported to affect sexual attraction (Wedekind et al., "MHC-dependent mate preferences in humans" (1995)), and estrateranol can affect social interactions. It has been found that smelling the estrateranol-containing odor increases feelings of trust and intimacy with others, and odor stimuli also affect women's responses to stressful situations (Francesca e al., "Olfactory cues from romantic partners and strangers influence women's responses to stress" (2017)).

According to one embodiment of the present invention, the pheromone is characterized in that it is at least one selected from the group consisting of androstenone, androstenol, androstadienone, and estratetraenol.

In the present invention, “skin moisturizing” means strengthening the skin barrier to prevent moisture from evaporating from the skin and blocking excessive penetration of external substances, thereby maintaining moisture in the stratum corneum of the skin and preventing the skin from drying out or having a rough surface, thereby allowing the skin to remain soft and moist.

In the present invention, the "active ingredient" means an ingredient that exhibits the desired activity alone or can exhibit the activity together with a carrier that is inactive itself.

In the present invention, the term "cosmetic composition" means a product used on the human body to cleanse and beautify the human body, add attractiveness, brighten the appearance, or maintain or improve the health of the skin and hair, and which has a mild effect on the human body.

According to one embodiment of the present invention, the pheromone is characterized in that it is included in an amount of 0.1 to 1 part by weight based on the total weight of the lip cosmetic composition. In this case, if the content is less than 0.1 part by weight, the intended effects of the present invention, such as skin moisturizing and gloss and fragrance enhancement, cannot be obtained, and if it exceeds 1 part by weight, the effect is not proportional to the increase in content, which may be ineffective.

Meanwhile, the present invention provides a method for producing a lip cosmetic composition, including: a step of forming a first mixture by mixing and stirring vegetable oil, natural wax, pheromone, and an additive at a temperature range of 80°C to 100°C; a step of forming a second mixture by adding a mattifying agent to the first mixture and mixing and stirring at a temperature range of 50°C to 80°C; a step of adding a colorant to the second mixture and mixing and stirring; and a step of producing a lip cosmetic composition by putting the second mixture with the colorant added into a mold.

Below, the method for manufacturing a lipstick composition is described in detail.

First, vegetable oil, natural wax, pheromone and additives are mixed and stirred at a temperature range of 80°C to 100°C to form a first mixture.

In one embodiment, the mixing and stirring may be performed at a temperature range of about 80° C. to about 100° C. If the mixing and stirring is performed at a temperature range of less than about 80° C., the components may not be sufficiently dissolved and may settle to the bottom, and if the mixing and stirring is performed at a temperature range of more than about 100° C., a change in the formulation may occur.

In addition to the effective ingredients, the lip cosmetic composition of the present invention may further contain components commonly added to cosmetic compositions, such as conventional auxiliary agents such as antioxidants, stabilizers, solubilizers, vitamins, pigments, and fragrances, and carriers.

The lip cosmetic composition of the present invention may further contain adjuvants commonly used in the fields of cosmetology or dermatology, such as fatty substances, organic solvents, solubilizers, thickening and gelling agents, emollients, antioxidants, suspending agents, stabilizers, foaming agents, fragrances, surfactants, film-forming agents, water, ionic or nonionic emulsifiers, fillers, metal ion sequestering and chelating agents, preservatives, vitamins, blocking agents, humectants, essential oils, dyes, pigments, hydrophilic or lipophilic active agents, lipid vesicles or any other ingredients commonly used in cosmetics. And, the above ingredients can be introduced in amounts commonly used in the field of dermatology.

The lip cosmetic composition of the present invention can be used alone or in multiple applications, or in multiple applications with other cosmetic compositions other than the present invention. In addition, the lip cosmetic composition according to the present invention can be used according to a conventional method of use, and the number of times it is used can vary depending on the skin condition or preference of the user.

In one embodiment, the mixing and stirring may be performed for about 1 minute to about 30 minutes. If the mixing and stirring is performed for less than about 1 minute, the components may not be uniformly mixed, and if the mixing and stirring is performed for more than about 30 minutes, a phase separation phenomenon may occur.

In one embodiment, the vegetable oil may include at least one selected from the group consisting of apricot kernel oil, avocado oil, rosehip oil, camellia seed oil, macadamia seed oil, and combinations thereof. The vegetable oil may not only enable the lipstick composition to exhibit smooth spreadability, but also provide a pharmacological effect and an excellent fragrance, thereby enhancing user satisfaction.

In one embodiment, the natural wax is added to provide moisturizing and long-lasting properties to the lipstick composition, and may include, for example, one or more selected from the group consisting of beeswax, carnauba wax, paraffin wax, and combinations thereof.

Natural waxes include carnauba wax, beeswax, candelilla wax, and Japan wax, while mineral waxes include solid paraffin, microcrystalline wax, ceresin, and hydrocarbon waxes.

Oil is a liquid type that melts at human body temperature and is divided into natural oil and synthetic oil.

In one embodiment, when forming the first mixture, at least one solvent selected from the group consisting of triglyceride, butylene glycol, hexylene glycol, ethoxydiglycol, and combinations thereof may be additionally included.

In one embodiment, the additive may include one or more selected from the group consisting of preservatives, flavoring agents, stabilizers, humectants, and combinations thereof.

For example, the preservative may include a natural preservative or a synthetic preservative, and may include one or more selected from the group consisting of, but not limited to, methyl paraben, ethyl paraben, propyl paraben, butyl paraben, quaternium-15, imidazolidinyl urea, phenoxyethanol, and combinations thereof.

For example, the stabilizer may include, but is not limited to, one or more selected from the group consisting of polyglyceryl-10 oleate, polyglyceryl-10 stearate, sorbitan oleate, and combinations thereof.

For example, the moisturizer may include, but is not limited to, one or more selected from the group consisting of glycerin, sorbitol, propylene glycol, sodium hyaluronate, and combinations thereof.

Next, a mattifying agent is added to the first mixture, and a second mixture is formed by mixing and stirring at a temperature range lower than the temperature at which the first mixture is formed.

In one embodiment, the temperature for forming the second mixture may be performed at a lower temperature than the temperature for forming the first mixture, for example, may be performed at a temperature range of about 50° C. to about 80° C. If the temperature for forming the second mixture is lower than about 50° C., the mattifying agent may not be evenly dispersed, and if it exceeds about 80° C., deformation of the formulation may occur. Therefore, it is preferable that the temperature for forming the second mixture be performed at a temperature range of about 50° C. to about 80° C.

Next, a colorant is added to the second mixture and mixed and stirred.

In one embodiment, after the step of forming the first mixture or the second mixture, a step of cooling may be additionally included, respectively. By additionally including the step of cooling, a phase separation phenomenon occurring during the formation of the first mixture or the second mixture may be prevented, but is not limited thereto.

In one embodiment, the cooling step may be performed at a temperature range of about 10° C. to about 20° C. for about 1 hour to about 6 hours, but is not limited thereto.

In one embodiment, the above components can be used in appropriate combinations as needed.

Finally, the second mixture containing the colorant can be placed into a mold to produce a lip cosmetic composition.

In one embodiment, in addition to the aforementioned components, additive components contained in a typical lip makeup cosmetic composition, such as polyol, conditioning agent, thickener, nutritional ingredient, etc., may be further included within a range that does not impair the effects of the present invention. The additives may be used without limitation as long as they are natural ingredients, but are not limited thereto.

According to one embodiment of the present invention, the lip cosmetic composition is characterized in that it is formulated in the form of a lipstick, lip balm, lip cream, lip pencil, liquid rouge or lip gloss.

As such, the lip cosmetic composition of the present invention has excellent skin adhesion, spreadability, and coloring power, so that it can be smoothly applied on the lips to exhibit excellent coloring, and it exhibits excellent durability to maintain high-quality makeup for a long time. In addition, the lip cosmetic composition according to the present invention has the advantage of being provided with high moisturizing properties without skin irritation. In addition, the glossiness of the lips can be increased and an attractive fragrance can be provided. Therefore, the lip cosmetic composition according to the present invention is expected to be very useful as a lip cosmetic composition not only having the effects of moisturizing the skin and increasing glossiness, but also having no cytotoxicity and skin side effects.

Hereinafter, in order to help understand the present invention, examples and the like will be described in detail. However, the examples according to the present invention may be modified in various different forms, and the scope of the present invention should not be construed as being limited to the following examples. The examples of the present invention are provided to more completely explain the present invention to a person having average knowledge in the art.
