Description

Oily cleansing cosmetic composition

The present invention relates to an oily cleansing cosmetic composition for cleaning the skin and a method for cleaning the skin using such a composition.

Olive is an evergreen tree of ash family, about 5 to 10 m high, with numerous branches. The leaves of the olive are opposite, long oval, with flat edges, and have scaly white hairs on the back. Olive flower is yellowish white, blooms in late spring and has a fragrance. Corolla is divided into 4 pieces, spreads out horizontally, and stamens have 2 pistils. The fruit of the olive is a nucleus (核果), oval-shaped and ripe in purple black. The olive is native to Turkey and has been cultivated since 3000 BC and spread early on the Mediterranean coast. It is active in hot dry summers and warm, humid winters such as the Mediterranean coast. The main producers of olives are Italy, Spain, Greece, France and the United States.

Olive oil obtained by squeezing the fruits of olives or olive extracts obtained by extracting olives is used for various purposes. Compared with mineral oils, it has high moisturizing properties and contains ingredients such as vitamin E and ceramide, and has good affinity with skin. It is known to prevent aging of the skin and to absorb moisture, making the skin hydrated. It is often used as a cosmetic ingredient. As an example, a cosmetic agent having an antioxidant, anti-aging and whitening effect of the skin including olive oil or olive extract, sorbitan group, polyglycerin group, ethylene oxide group, etc. are introduced into the fatty acid derived from olive oil, and a surfactant and an emulsifier Various cosmetics used as stabilizers, etc. are presented in Korean Patent Application No. 10-2003-0071417. In addition, olive oil esters produced by esterifying fatty acids derived from olive oils have similar emulsifier properties as olive oils, but are lighter than olive oils, have better stability at high and low temperatures, and are compatible with hydrocarbon oils and silicone oils. It is used in cosmetics of formulations that are hard to be applied to olive oil because of its good properties.

Meanwhile, cleansing cosmetics for removing makeup can be classified into aqueous cleansing cosmetics and oily cleansing cosmetics. Recently, a lot of oily cleansing cosmetics can be quickly removed and washed with water by omitting the process of cream or gel. It is commercially available.

Since the oily cleansing cosmetics contain almost 100% of liquid oil components without containing an aqueous component, they have an excellent cleansing effect by easily cleaning skin contamination such as makeup, contamination from the external environment or human origin. However, since oil-based or ester-based oils are used as oil components of the oil-based cleansing cosmetics at 10 to 90% by weight or more relative to the total weight of the cosmetics, it is difficult to diversify the feel of the cleansing cosmetics, surfactants and mineral oils having cleaning power, There is a problem that the compatibility of oil components such as ester oil, silicone oil, etc. is separated into two layers at room temperature. In addition, since the oily cleansing cosmetics have a low viscosity, it is easy to flow, so there is inconvenience in use, and if the oil components remain on the skin after cleansing, the washability is poor, and the second wash after washing with water is troublesome. There have been attempts to change the type and ratio of nonionic surfactants used in oil-based cleansing cosmetics in order to solve the hassle of the second face wash, but no progress has been made.

Therefore, the problem to be solved by the present invention is an oil-based cleansing cosmetic composition that can provide a rich nutrients and massage feeling as well as having excellent cleaning power so that secondary cleaning is unnecessary, while removing the makeup and the contamination of the skin cleanly and It is to provide a method for cleaning the skin using a cosmetic composition.

In order to solve the above problems, the present invention provides a cleansing cosmetic composition comprising 0.5 to 80% by weight of PEG olive ester and 1 to 95% by weight of oil derived from olives relative to the total weight of the composition.

The oily cleansing cosmetic composition according to the present invention includes PEG olive ester, which is a water-soluble surfactant, which can easily remove makeup and skin contamination, as well as cleansed by water washing. Therefore, it is possible to improve the inconvenience of the secondary cleaning according to the oil component remaining on the skin after cleansing, which was a big problem of the conventional oily cleansing cosmetics. That is, the oily cleansing cosmetic composition of the present invention may exhibit an excellent cleaning ability compared to the conventional oily cleansing cosmetics due to the water-soluble properties.

In addition, the use of PEG olive ester derived from olive oil, which is widely used in cosmetics and food, etc., has the advantage of being safer to the human body and the environment and providing nutrition to the skin.

In addition, the conventional oil-based cleansing cosmetics have excellent compatibility between oils derived from olives and PEG olive esters, which are water-soluble surfactants of the present invention, in contrast to surfactants having a detergency and low oil compatibility. It has the advantage of superior phase stability even when stored at room temperature for a long time.

At the same time, the present invention can maintain a good coating feeling and cleansing power by using a large amount of oil derived from olives, while using a olive oil PEG as a nonionic surfactant, compared to the conventional oil-based cleansing cosmetics, there is less flow down Excellent feeling.

Accordingly, the present invention provides a cleansing cosmetic composition comprising a PEG olive ester and an oil derived from olive, which can be used to easily clean up the makeup and the contamination of the skin. That is, the present invention also provides a method for cleaning skin, characterized by using the cleansing cream cosmetic composition according to the present invention.

PEG olive esters according to the invention can be produced in a variety of ways using olive oil and polyethylene glycol (PEG), preferably by the transesterification of olive oil and polyethylene glycol (PEG), or fatty acids of olive oil Produced by esterification of polyethylene glycol (PEG) with polyethylene glycol (PEG).

The PEG olive ester includes PEG-7 olivate, olive oil PEG-7 ester, and the like, and the PEG olive ester has a form in which a polyethylene glycol (PEG) having a hydrophilic group is bound to the fatty acid of olive oil. As a result, the properties of olive oil which are not mixed with water are improved to have a property of being dispersed or dissolved in water. Preferably the fatty acid derived from the olive oil has 12 to 24 carbon atoms.

The PEG olive ester is preferably included in an amount of 0.5 to 80% by weight based on the total weight of the composition, when the content is less than 0.5% by weight, the cleaning power is insignificant, and when it exceeds 80% by weight, it may cause dry skin. It is not preferable because manufacturing cost can be raised.

In particular, very surprisingly, it has an average of 4 to 10 moles, preferably 6 to 8 moles of ethylene oxide group (-(OCH ₂ CH ₂ ) and has a hydrophile-lipophile balance (HLB) of 8 to 12 to characterize the hydrophilic emulsifier. The PEG olive ester of the present invention is particularly preferred because of its good compatibility with oils derived from olives and excellent phase stability without separation of the layers at room temperature.

As an oil derived from olives according to the present invention, an olive oil obtained by compressing and refining an olive fruit or its shell, an olive squalane produced by adding hydrogen to the olive oil, and a fatty acid derived from the olive oil are esterified. The resulting olive oil esters such as ethylhexyl oleate, ethyl oleate, hydrogenated ethyl hexyl oleate may be used alone or in combination of two or more, but are not limited to the above specific types, and are generally oils derived from olives. As long as it is used for a cosmetic composition, any can be used. Preferably the content of the oil derived from the olive is 1 to 95% by weight based on the total weight of the composition, preferably 50 to 90% by weight based on the embodiment, it can exhibit an excellent coating and massage feeling in the range of the content. .
