Description

Capsulated cosmetics using the membrane composition for capsulating cosmetics}

The present invention relates to a cosmetics encapsulated using a film composition for cosmetic capsules. More specifically, the present invention relates to a cosmetic encapsulated using a film-like composition for the capsule to improve the preservation and usability by encapsulating the cosmetic.

Cosmetics are mainly used to apply moisturizing factors or nutrients to the skin to keep the skin healthy and clean, except for cosmetics that enable various color expressions, such as cleanser or rod cosmetics commonly referred to as 'lipsticks'. It is main function to do.

Cosmetics for moisturizing and nourishing the skin are mainly prepared by emulsifying the aqueous components in the oil based on the oil components, which is commonly referred to as W / O type (Water in oil type) cosmetics.

Such conventional W / O type cosmetics are emulsified with aqueous components in oily ingredients, and have excellent stability and high preservation, but have a disadvantage in that the feeling of use is poor due to the residual stickiness peculiar to oil components when used on the skin. Almost all commercially available cosmetics include color cosmetics such as Make-Up Base Cream or Foundation Cream.

Meanwhile, in order to protect bioactive substances such as vitamin C and retinol among the conventional cosmetics, collagen and gelatin were used alone as membranes for encapsulation, but general cosmetics, especially makeup base creams, were used alone. The encapsulation of emulsifiers such as or foundation creams has never been developed.

Therefore, in the present invention, a number of studies and experiments have been repeated to prepare and provide the optimum film composition to produce a film composition and completed the present invention.

An object of the present invention is to provide a cosmetics encapsulated using a film composition for cosmetic capsules for the production of cosmetics having excellent storage stability, without stickiness.

Cosmetics encapsulated using the film-like composition for cosmetic capsules according to the present invention, carrageenans (Carageenans) 1.5 to 3.0% by weight, algin 0.5 to 1.5% by weight, agar (agar) 0.1 to 0.2% by weight, alkaline earth metal silicate Cosmetic composition of W / O (water in oil) or W / S (water in silicon) formulation including makeup base cream or foundation cream as a film composition comprising 0.05 to 0.2% by weight of inorganic fillers and deionized water as the remaining amount Coating or vitamin C (Vitamin C), bioactive substances including retinol is formulated in the form of W / O or W / S and then coated and encapsulated.

Hereinafter, the present invention will be described in detail with reference to specific examples.

Cosmetics encapsulated using the film-like composition for cosmetic capsules according to the present invention, carrageenans (Carageenans) 1.5 to 3.0% by weight, algin 0.5 to 1.5% by weight, agar (agar) 0.1 to 0.2% by weight, alkaline earth metal silicate It is a membrane composition consisting of 0.05 to 0.2% by weight of inorganic fillers and deionized water as a residual amount, and is encapsulated by coating conventional cosmetics such as makeup base cream or foundation cream and bioactive substances such as vitamin C and retinol. Characterized in that made.

Carrageenan, algin, and agar are all known to the extent that they are commercially available to those of ordinary skill in the art as a raw material for general cosmetics well known in the art. In the present invention, the carrageenan, algin and agar are suitably blended to form a film-like composition for encapsulating the cosmetic.

The carrageenan, algin, and agar are all water swellables, which swell in water, shrink in dehydrated state, do not melt completely in water, and exhibit adequate expansion and contraction properties.

Inorganic fillers of alkaline earth metal silicates form part of the membrane together with the carrageenan, algin and agar, and are understood to play a role of improving the stability of the capsule by enhancing the mechanical properties of the obtained capsule.

The film-like composition comprising the above components may be in a swelled state or in a contracted state depending on whether moisture is impregnated, and may be suitably used to encapsulate the cosmetic.

The cosmetics to be encapsulated, such as the makeup base cream or foundation cream, may further include a preservative for long-term preservation and especially for inhibiting the growth of microorganisms. As the preservative, commercially available preservatives of parabens such as methyl paraben or phenyl paraben may be used.

The makeup base cream or foundation cream and the like can be used commercially available color cosmetics as cosmetics of the representative W / O or W / S formulations, bioactive substances including vitamin C (Vitamin C), retinol W / O or W / It is possible to double the stability of the bioactive substance by formulating it in S form.

For encapsulation, a method similar to or similar to that of a conventional cosmetic encapsulation may be used.

For example, the carrageenan 1.5 to 3.0% by weight, algin 0.5 to 1.5% by weight, agar 0.1 to 0.2% by weight, 0.05 to 0.2% by weight of inorganic fillers of alkaline earth metal silicates and the residual amount of deionized water to about 80 ℃ At the same time, the cosmetics to be encapsulated, that is, the makeup base cream or the foundation cream, are also mixed with the preservative at a temperature of about 80 ° C. and stirred until homogeneous. The agitated membrane composition and cosmetics can be achieved by injecting into a tank to which the nozzles are connected and dropping the mixture of membrane composition and cosmetics into the oil bath containing mineral oil at room temperature through the nozzle while continuing to stir.

The mineral oil is also known enough to be commercially available in the industry, it can be commercially available under the trade name 'LP (L / P)'. However, the present invention is not limited to the mineral oil itself, wherein the role of the mineral oil is to lower the water content of the membrane composition and to drop the temperature of the capsule into the oil tank to cure the membrane composition in the dropping capsule. Decreases the function. That is, the capsule dropped while heated to about 80 ℃ is cooled into the mineral oil of the room temperature state in the oil bath, and accordingly, carrageenan, algin and algin by the decrease in water content and cooling in the film composition constituting the capsule As the raw material of the swollen membrane such as agar is contracted to form a hard capsule membrane, the oily cosmetics are collected in the cured membrane composition while being cooled to obtain a capsule having excellent stability.

At this time, the carrageenan, algin, and agar constituting the capsule are all water-based ingredients, so that they do not appear sticky when applied to the skin.

The obtained product can be taken out of the mineral oil and added to a preservation solution to be preserved in the form of an intermediate product, and can also be added to an essence, which is one of ordinary cosmetics, and encapsulated in a container to complete the product.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.
