Description

            Method for preparing amphipathic lipid-based multi-emulsion lipstick composition         

The present invention is the amphiphilicity of gelling amphoteric lipids and water in a stable state to impart excellent skin protection effect of lipid components and moisturizing function in the lips skin.                 The present invention relates to a method for preparing a lipid-based emulsion emulsion composition.

In general, the quality of lipstick is mostly determined by the prescription of a fat base, and the quality of the base is closely related to the rheology of the mixture. Thus improving the quality of the lipstick                 In order to have moderate thixotropy, it does not bleed and spread well under the influence of such thixotropy, and has moderate adhesion on the lips,                 There should be no persistence, expressiveness, stability, sweating, and proper gloss on the appearance.                 do.

Conventionally, a process for producing a lipophilic emulsion lipstick is known, in which an oil phase is formed with a lipophilic emulsifier of oils and waxes, an aqueous phase and an oil phase are mixed, heated, and emulsified.                 However, these products were inconvenient to manufacture and the moisturizing effect of the lipstick and the care function of the lips were not clear.

In particular, the lips are quite different from the skin of other parts of the human body, and there is no sebaceous gland and the stratum corneum is so thin that the superficial layer is not acute. Also in other areas                 NMF (Natural Moisture Factor) value in skin is 0.76μmol / mg, whereas NMF value in lips is low as 0.12μmol / mg,                 The rate of evaporation is 11-19 g / (m / hr) for the skin, whereas the lips tend to dry fairly quickly at 40-78 g / (m / hr). Moisture is normal skin                 30 ~ 39μΩ and lip skin is 16 ~ 25μΩ, much less moisture than normal skin. Due to these characteristics, when compared to normal skin,                 When the volatility of moisture reaches 6 times and proper moisturization is not achieved, the lips are gradually opened or rough due to environmental factors and internal and external factors of the lips.                 The condition is accelerated. It is difficult to expect a lip care effect by simply applying oil and wax to protect the lips, and it protects the lips by the oil seal.                 Expectations are low expectations. In addition, lipophilic lipstick compositions using lipophilic emulsifiers do not have functional aspects, particularly strong water repellency, and color.                 The long lasting effect is not satisfactory.

Conventional emulsion lipsticks have a cohesive phenomenon when water and an inorganic pigment come into contact with each other, resulting in a feeling of stickiness, roughness, and saturation with changes over time.                 When applied to the lips, a characteristic whitening (white color) phenomenon occurs as an emulsified product. In addition, as the moisture vaporizes from the surface of the lipstick,                 Lipsticks shrink irregularly with significant loss, and in extreme cases, the body of the lipstick bends irregularly.

As is well known, the lamellae structure of the stratum corneum refers to the association of lipids and water, the skin consists of several layers of layers, one third of the skin's moisture                 It is retained by the lamellar structure and the rest is by the binding water of keratin. Water molecules surrounded by the lamella structure will disappear unless the lamella structure is destroyed                 Do not.

Conventional emulsion lipstick products are easily broken down in the skin and are divided into water and oil. In this state, the thin oil film has a weak closing property and moisture is quickly lost.                 Throw it away. However, in the case of the lamellar structure, the same structure as the stratum corneum exists on the skin, thereby retaining moisture and at the same time exhibiting strong obstructive properties.

In recent years, intercellular lipids have been attracting attention because the water retention function of the stratum corneum, which is a moisture protection function of the skin, is not a water-soluble component but a lipid having a lamellar structure.                 70% of the human body is present in the water, but the moisture in the atmosphere is extremely small and it prevents the large water gap caused by the epidermis.                 As a fence layer, only 0.1 mm of thin leather prevents the evaporation of moisture. These epidermal repair functions in the stratum corneum by lamellar structure by intercellular lipids and binding water                 Because you are drunk.

Moisture in the skin is present as a binding water bound by intercellular lipids or keratin proteins and hydrogen bonds.                 The stratum corneum does not freeze at 0 ° C. This is the same principle that the mucous membranes swell in the water but the stratum corneum of the skin does not swell in a moist place such as a bathroom. this is                 The structure of the stratum corneum, ie lamellar structure, proves to be less susceptible to external changes.

Accordingly, the present inventors, after repeated studies to solve the above-described problems, by using amphiphilic lipids to form a multi-layer with water or water phase components                 Development of an amphiphilic lipid-based multi-emulsion lipstick composition with enhanced moisturizing function on the lips along with the enduring effect of color that is a unique function of lipstick                 It was completed. At the same time, the water phase component is maintained in the oil phase / water phase / oil phase stably so that the aggregation of the pigment does not occur and the loss of water in the multilayer structure is achieved.                 By inhibiting and prolonging the retention time on the lips, it has developed a long lasting microcapsule emulsion with a moisturizing effect on the lips.

Accordingly, an object of the present invention is to provide a method for preparing an amphipathic lipid-based multi-emulsion lipstick composition excellent in color sustainability and moisturizing function.

In order to achieve the above object, the amphipathic lipid-based lipstick composition which is a mixture of the nonionic surfactant and the amphiphilic lipid-based liposome of the present invention is pioi sterosterol                 0.1-40%, Cholesterol 0.1-40%, Citosterol 0.1-40%, Polyoxyethylenecetyl ether 0.1-40%, Diecetyl phosphate 0.1-15%,                 And an amphiphilic lamellar structure containing 0.1-20% glycerin, 0.1-20% water and 0.1-20% moisturizing component. The moisturizing component is                 40% by weight sodium hyaluronate, 30% by weight perfluoropolyether, 10% by weight sodium pyrrolidone carboxylate, 5% by weight honey extract, 5% by weight propylene glycol and                 It consists of 10% by weight of 1,3-butylene glycol.

The method for preparing the amphipathic lipid based multi-emulsion lipstick composition of the present invention will be described in detail below.

The lipid base used in the present invention is prepared by the composition ratio of each component shown in Table 1. First, the phase A is dissolved by heating at 80 ° C., and the phase B and the phase C are separated.                 Dissolve. Phase B is introduced into phase A, followed by a wetting process, and at an appropriate temperature. Then, a moisturizer (sodium hyaluronate and perfluoropolyether), which is phase C, is added, and then uniform.                 Pressurized through a high pressure mixer in a dispersed state and then cooled to 30 ° C. The lipid base is pioi cytosterol, the most similar to the structural components of human skin,                 It is resistant to the stratum corneum for lips skin without sweat glands and stratum corneum, which are based on cytosterol and cholesterol and contain a lot of water and moisturizing substances.                 There is a strong moisturizing function similar to the function of maintaining the moisturizing power.
