Cosmetic Composition for Reducing Stickiness and Improving Transparency of Emulsion Formulation

The present invention is for reducing stickiness and improving transparency of an emulsified formulation comprising a mixture of polyglyceryl-10 eicosanedioate/tetradecanedioate, panthenol and malachite extract It relates to a cosmetic composition, and more particularly, polyglyceryl-10 eicosandioate/tetradecanedioate, which improves transparency by lowering blue color due to malachite extract while reducing stickiness due to panthenol contained in an emulsion formulation. , to a cosmetic composition comprising a mixture of panthenol and malachite extract as an active ingredient.

Cosmetics are used directly on the skin to make the skin clean, healthy and beautiful, and are manufactured by mixing water-soluble substances, fat-soluble substances, and powders. The water-soluble and oil-soluble substances of cosmetics do not mix with each other, so a layer separation occurs during mixing. To prevent this, a surfactant is used, and it serves to mix the immiscible aqueous phase, oil phase, and other ingredients in a stable micro-mixed form.

Surfactants used in cosmetics include stabilizers such as emulsifiers, solubilizers, and dispersants, as well as detergents, transdermal absorption accelerators, skin efficacy enhancers, antistatic agents, and the like. liquid)).

The dictionary meaning of emulsion is a colloidal system in which droplets or liquid crystals are dispersed in a liquid, and any one of the non-miscible or partially mixed phases is dispersed in another liquid serving as a dispersed phase and is in a droplet state. is defined

The surfactant in the emulsion is adsorbed on the surface of the droplet to reduce the interfacial tension of the aqueous phase and the oil phase, thereby preventing aggregation or coalescence of the prepared emulsion. technique) emulsification method, D-phase (detergent phase) emulsification method, low temperature emulsification method, liquid crystal phase emulsification method, high pressure emulsification method, etc. Recently, as interest in nanoemulsion increases, research on high pressure emulsification method is actively conducted is becoming

The most common type of emulsion is an oil-in-water (O/W) emulsion, in which oil particles with a size of 0.5 to 5.0 μm are dispersed in an aqueous phase. accounts for more than 90% of

A Water in Oil (W/O) emulsion is a form in which aqueous phase particles of 0.2 to 1.0 μm in size are dispersed in an oil phase. being used in products.

These emulsions are used to solubilize poorly soluble substances and are used as carriers for external skin preparations and target-oriented active ingredients (drugs, etc.) The interfacial tension between the two phases increases, resulting in an increase in the interfacial tension between the two phases, which makes them thermodynamically unstable.

In addition, most of the active ingredients of water-soluble and oil-soluble cosmetics are easily oxidized by external factors such as air, heat, light, oxygen, etc. in aqueous solution or atmosphere, and thus there is a problem in that the potency decreases and discoloration occurs over time.

Therefore, one of the important tasks of the industry using the emulsion is to prepare an emulsion with improved storage stability by preventing phase separation for a desired period and suppressing the decrease in titer and the occurrence of discoloration.

As such, the emulsified cosmetic composition is largely classified into oil-in-water (O/W emulsion) and water-in-oil (W/O emulsion). Water-based creams have very good makeup durability and water resistance because the outer part is oil, but they give a heavy and stuffy feeling due to oil, and have problems with low long-term stability of the emulsion.

The skin is an important organ that protects the human body from the external environment, and is responsible for various physiological functions, such as a barrier function that prevents internal moisture and useful components from leaking out, and body temperature regulation and excretion. However, due to skin stress caused by various environmental pollution, deterioration of cell function due to aging, and photoaging by ultraviolet rays, the skin's nutrition and moisture are insufficient, and the metabolism is not smooth, and aging is accelerated.

In order to delay skin aging as described above, cosmetic compositions of various formulations having excellent moisturizing power are being developed. As the ingredients used to increase the moisturizing power, polyols such as glycerin, butylene glycol, propylene glycol, polyethylene glycol, and sorbitol are used as moisturizing agents. Polyols have the ability to contain water. It is good, but it has shortcomings in terms of moisture retention, and when it is applied to the skin, it is sticky or has a dull, damp feeling. On the other hand, oils that form a closure film generally have high moisture retention, but have disadvantages such as stickiness, slow absorption, and shine. In order to solve the shortcomings of these ingredients and to highlight the advantages, cosmetic compositions and formulation technologies using various ingredients have been developed, and research has been conducted to give cosmetics a new function, appearance, and texture. In particular, the anhydrous formulation is a formulation stabilized using a polyol with excellent water holding ability and oil with excellent moisture retention. However, it still has problems such as instability over time and a feeling of heavy and stuffy use (refer to Korean Patent Registration 10-1404969).

Polyglyceryl-10 eicosanedioate / tetradecanedioate (polyglyceryl-10 eicosanedioate / tetradecanedioate) is a monoglyceride (monoglyceride), diglyceride of eicosanedioic acid and tetradecanedioic acid (tetradecanedioic acid) As a mixture of (diglyceride) and triglyceride (triglyceride), it is generally used as an emollient (emollients) of a cosmetic composition for improving the moisturizing function of skin and hair.

Panthenol is an alcohol derivative of pantothenic acid (vitamin B ₅ ), also called provitamin B5, D-panthenol, Dexpanthenol, L-panthenol, and a mixture thereof, D ,L-panthenol (D,L-panthenol). Pantothenic acid is a substance present in living cells and tissues of the body, and is known as an essential element for normal cell metabolism and hormone production. In terms of formulation, D-panthenol is a viscous oil, and D,L-panthenol is in the form of a creamy white crystalline powder. Both D-panthenol and L-panthenol act as humectants, emollients, and moisturizers, and improve skin and hair moisture retention. In particular, D-panthenol has biological activity, so it is converted into pantothenic acid when it penetrates the skin, resulting in cell division and proliferation. It is effective for skin regeneration, normalization of the keratinized shape of the skin, wound healing, moisture supply, and anti-inflammation.

Malachite is derived from the Greek word "Mala'Khe" meaning "the color of mallow" and is an ore formed by the weathering of copper deposits, also called malachite. In ancient Egypt, it was also considered a sacred stone. Malachite contains hydrated copper carbonate (Cu ₂ (OH) ₂ CO ₃ ) as its main component, and contains manganese, silicon, and zinc as other components, so it is effective for body detoxification, tissue treatment, and smooth energy flow. It is effective, and has been used to balance and harmonize body tissues and organs, and has also been used for eye and face treatment and makeup.

Trace elements are chemical elements found in the human body in concentrations of 0.01% or less, and are divided into essential trace elements and non-essential trace elements. In general, if one or more function changes are caused during element deficiency and the function is restored through proper intake, this trace element can be called an essential trace element. is responsible for 15 essential trace elements: fluoride, iodine, selenium, silicon, chromium, cobalt, iron, lithium, manganese ), molybdenum, nickel, copper, tin, vanadium, and zinc among the four elements copper, manganese, silicon and zinc play a major physiological role in the skin. contribute

Malachite contains all four components of copper, manganese, silicon and zinc, and can be utilized as a new mineral source for stressed skin. In particular, copper, the main component, promotes keratin synthesis in keratinocytes, has antioxidant effects, increases collagen and elastin synthesis by activating lysyl oxidase, and protects skin from light by synthesizing melanin precursors also plays a role.
