Hair cleansing composition with microemulsion phase

The present invention relates to a hair cleanser composition comprising a microemulsion phase, and more particularly, to easily micronize a large amount of oily potent ingredients, to provide a proper cleaning effect on hair and to conditioning and viscosity formation when wet, and to temperature. It relates to a clear or opaque phase detergent composition having good phase stability.

Recently, hair has been damaged by wind, heat, sun, pollution, and many other causes, and much attention has been paid to protecting hair from these causes. As hair is damaged by physical, chemical, and environmental factors such as frequent perm and dyeing, roughness increases, and luster loses softness and softening effect frequently. Accordingly, the friction force increases, making it difficult to clean the hair by combing and the like, such that the hair is cut off or the tip is cracked.

In order to solve this problem, the constant research on cleaning agents or cosmetics to improve the softness of the hair at the time of cleaning or after cleaning and to restore damaged hair has been continued. In particular, in order to protect hair, prevent damage, and give conditioning effects to shampoos that have conventionally emphasized cleaning functions, so-called conditioning shampoos have been developed and put into practical use in addition to the cleaning surfactant as a main ingredient. Usage is on the rise.

Generally, the hair cleaner composition uses an anionic surfactant having excellent cleaning power and bubble generation power as a main component. In particular, it is an anionic surfactant having good foaming ability and excellent detergency. Alkyl sulfonate having about 12 (lauryl) to 14 (myristyl) or sulfonate added with 2 to 5 polyoxy ether groups is mainly applied. have. Various oily ingredients such as oil and silicone may be included to protect the hair, but when the amount of these oily ingredients increases, the appearance of the composition cannot be kept transparent, the foaming power decreases, and the stability deteriorates over time, resulting in phase separation. There is a disadvantage that appears. In order to solve these problems, Korean Patent Publication No. 1983-0001400 uses a method of stabilizing excess oil by heating a high temperature to make a microemulsion base separately, but this heating premix process is complicated in manufacturing process, There is a disadvantage that a lot of energy is consumed.

Korean Patent Publication No. 10-2006-0120175 introduces a method of stabilizing oily components using hydrophilic and lipophilic nonionic surfactants, but the composition of the nonionic surfactant has a weaker foaming ability and detergency than the anionic surfactant. There are disadvantages.

Therefore, the technical problem to be achieved by the present invention is to include a large amount of oily hair protection ingredients, there is no tangling or jamming of the hair during wetting and rinsing during the cleaning process, excellent in the conditioning effect, easy manufacturing process, stability over time at low temperature and high temperature It is to provide this excellent hair cleaning composition.

The present invention to achieve the above technical problem (a) anionic surfactants; (b) glyceryl ester derivatives; And (c) a hair protecting oily component, by appropriately adjusting the ratio of each component and water to provide a microemulsion-containing hair cleanser composition which is easy to manufacture and excellent in stability.

More preferably, the microemulsion of the present invention further comprises (d) nonionic and / or amphoteric surfactants.

Hereinafter, the hair cleaning composition of the present invention will be described in more detail.

The present invention provides hair cleanser compositions using microemulsion techniques through certain ingredients.

Microemulsion is a technique for providing a more uniform and stable composition by emulsifying the oily part and the aqueous part which cannot be uniformly mixed with each other through the specific composition of each component, or by emulsifying the oily part as fine particulate oil in the aqueous phase. As a method for producing such a particulate emulsion, when hydrocarbon oil is added to a non-ionic surfactant solution of high HLB, the solubilization amount of hydrocarbon oil is rapidly increased in front of the cloud point of the non-ionic surfactant (Goshino Shinzo, " Solution and solubility ", Maruzen, 1991, p. 209-225), a combination of anionic and auxiliary surfactants to balance the hydrophilic-lipophilic, using a range of rapidly increasing solubilization of hydrocarbon oil in its very narrow range. And adding electrolytes to lipophilic nonionic surfactants and certain ionic surfactants, or lipophilic nonionic surfactants and ionic surfactants, to rapidly increase solubilization in a narrow proportion of hydrophilic-lipophilic balances. Method (Goda Shinoda, Hiroyuki Saizo, Yu Chemical, 35, 1986, p.308-314), silicone oil and silicone surfactant, hydrophilic A combination of a hydrophilic surfactant - how to adjust the balance chinyu there are known methods such as (Japanese Kokai Publication Hei-10-120524).

However, the conventional techniques are very limited, such as can achieve the purpose only in a specific composition, the manufacturing method and the raw material selection is complicated, long-term stability over time is not easy to maintain.
