Description

Oily cleansing cosmetic composition < RTI ID = 0.0 >

More particularly, the present invention relates to a cosmetic cleansing composition comprising 3 to 30 wt% of a nonionic surfactant derived from a natural cosmetic composition, 5 to 30 wt% of an oily gelling agent, and 40 to 92 wt% To a cleansing and massaging agent.

Cleansing and cleansing are an early stage of the beauty system and are very important cosmetic actions. Removing excessive sebum or make-up cosmetics and proceeding to the next treatment step is a necessary condition to prevent skin troubles and protect healthy skin condition. There are endogenous and exogenous dirt on the target skin. Excessive sebum, exfoliated keratin, metabolic materials such as stratum corneum, foreign dust and dirt, make - up cosmetics, etc. It is important to keep your skin clean because sebum and make-up cosmetics are left to oxidize and cause inflammation, edema, pigmentation or microbial propagation and cause acne.

As a cleansing cosmetic for cleansing the skin, there are various products, and it is known that it is in the form of cream, oil, liquid, and powder. If this is classified as a prescription composition, an aqueous cleansing cosmetic composition containing an aqueous component as a main component and optionally containing a surfactant, an emulsifying cleansing cosmetic composition containing an aqueous component, an oily component and a surfactant, and an oily component as a main component, An oil-based cleansing cosmetic compounded with a surfactant, and a powder-based cleansing cosmetic compounded with an enzyme mixed with a hydrophilic surfactant powder. Further, it can be classified into emulsion type, oil type or aqueous type.

Emulsion types are exemplified by cleansing lotions and creams, which are known to have excellent cleansing effect on cosmetics and excellent softness and massage effect when using oily ingredients in an amount of 20 wt% to 70 wt%. However, these emulsion types have to be wiped off with a tissue off because they can not be completely rinsed out with water due to the use of a large amount of oil after use, which may cause skin irritation due to physical stimulation. Even after wiping with a tissue, And it is inconvenient to use water cleansing using foam cleansing or soap.

The aqueous-type cleansing gel can be divided into a microemulsion gel type using a large amount of nonionic surfactant and a large amount of oil, and a cleansing gel type using anionic surfactant. The content of the surfactant is 10 wt% to 40 wt. < / RTI > The microemulsion gel type using a large amount of oil has a good cleansing power because it contains a large amount of oil and a surfactant. However, there is a feeling of use that is stiff and the oil remains on the skin after use, so it is difficult to wash it completely with water. On the other hand, a cleansing gel type using an anionic surfactant uses an anionic surfactant without using oil, so it can be easily washed with water and is neat when used. However, the cleansing effect for removing makeup is poor and skin irritation due to anionic surfactant There is a problem that is worried.

On the other hand, oily type cleansing oil uses almost 100% oil, so it has excellent make-up cleansing effect and excellent washability. However, despite the excellent cleansing power, the cleansing oil has a disadvantage that it flows down from the hand when used, and there are consumers who do not prefer this type of cleansing. In order to improve the disadvantages of the usability which flows down from the hand, an oil-based gelling agent such as organic bentonite, silicic acid hydrate, silicic acid anhydride, and dextrin fatty acid ester is mixed (Japanese Patent Application Laid-Open No. 62-108806) or an aerosol mixed with dextrin fatty acid ester (Japanese Patent Application Laid-Open No. 7-277954), waxes such as polyethylene, and oil-based solid cleansing agents (Japanese Patent Laid-Open No. 2001-213726, Korean Patent Application No. 10-2005-0090201, Korea Patent Application No. 10-2007-0080644).

However, since the wax or oily gelling agent described above is excellent in adhesion to the skin, it is difficult to obtain a refreshing feeling because it leaves a stickiness and an oily feeling when wiped off or washed after use. In addition, because it is a petroleum-derived synthetic raw material, there is a possibility that a skin trouble may occur when it is left on the skin, which does not fit the current well-being trend favoring natural products. The present surfactant used in the present oil cleansing cosmetic uses a surfactant made by adding polyethylene glycol, which has the effect of washing off the water well, but it has excellent emulsifying power, Has a disadvantage of causing irritation to the skin and excessively removing sebum, thereby causing skin dryness.

Accordingly, it is an object of the present invention to provide a cleansing cosmetic composition containing a novel naturally occurring surfactant which is improved in disadvantage of cleansing oil's flowing feeling while enhancing cleansing and massage effect and is free from stickiness and greasy feeling at the time of use and washing Development is needed.

Accordingly, the inventors of the present invention have conducted research on oily cleansing cosmetic compositions containing a naturally occurring surfactant, and have found that when 3 wt% to 30 wt% of a naturally occurring nonionic surfactant, 5 wt% to 30 wt% of an oily gelling agent, And a cleansing cosmetic composition containing oil-based oil components of 40 wt% to 92 wt% did not flow down and at the same time had an excellent washing power, thereby completing the present invention.

An object of the present invention is to provide an oily cleansing cosmetic composition containing a naturally occurring nonionic surfactant and having an excellent detergency and a feeling of use that does not flow down.

In order to solve the above problems, the present invention provides a cosmetic composition comprising 3 wt% to 30 wt% of a nonionic surfactant, 5 wt% to 30 wt% of an oily gelling agent, and 40 wt% to 92 wt% Wherein the cosmetic composition is an oil-based cleansing cosmetic composition.
