Description

Hair care composition

The present invention relates to a hair care composition. More specifically, the present invention relates to a hair care composition suitable for use in various hair products including hair conditioners, hair rinses, shampoos and the like.

Korean Patent Application No. 10-2015-0006005, No. 10-2015-0006006, and No. 10-2015-0006007, both of which are filed on January 13, 2015, and all of which are on December 8, 2015 Japanese Patent Application No. 10-2015-0174301, No. 10-2015-0174305, and No. 10-2015-0174316, the entire contents of which are incorporated herein by reference. Used for all purposes of this case.

Hair is similar in importance to a person's face. It is an important factor in determining a person's overall appearance and is a key way for a person to express his or her vitality and image. Therefore, people have been developing a hair care composition which can not only clean the hair but also achieve a care function of keeping the hair shiny and elastic. One of the most basic themes in these studies is based on different situations, such as when the hair is kept moist after shampooing (before the hair dryer), and after the hair is dry, by moisturizing the hair. Good state. To this end, new ingredients and compositions have been developed and formulated into shampoos, conditioners and care products.

In particular, the development of cationic surfactants, higher alcohols, and higher natural oils which allow the user to feel sufficient moisturization, gloss, smoothness and softness of the hair has been attracting attention. Korean Patent No. 1,351,473 discloses a novel ammonium compound which is used together with a cationic surfactant to broaden the feeling of hair massage, the feel of shampooing, and the smoothness of wet or dry hair. However, the degree of enhancement did not reach the desired value, and the stimulation of the scalp could not be significantly reduced due to the nature of the quaternary ammonium. Further, the use of a silicone resin such as dimethylpolyoxyalkylene reduces the foaming ability (the ability to form a foam).

Polymers of Chemical Formulas 1 to 3 are commercially available or can be synthesized.

For the latter (polymers of Chemical Formula 1 to Chemical Formula 3 can be synthesized), the polymers of Chemical Formulas 1 to 3 can be obtained by using a polar polymer (polyethylene glycol, polypropylene glycol, poloxamer, etc.) The saturated fatty acid is reacted and then esterified (between OH and COOH) to synthesize.

The unsaturated fatty acid can be obtained by subjecting the vegetable oil to antifreeze treatment to remove saturated fatty acids and then obtaining by distillation, for example, from soybean, camellia, green tea seed, ginseng, olive, avocado, sesame, safflower, and vegetables. Vegetable oils such as seeds, peach kernels, palm kernels, ramie, sunflower seeds, cottonseed, coconut, apricots, etc. For example, soybean oil (100 grams) contains 16 grams of saturated fatty acids, 23 grams of monounsaturated fatty acids, and 58 grams of polyunsaturated fatty acids. Among the saturated fatty acids, 4% stearic acid and 10% palmitic acid are present. Among the unsaturated fatty acids, α-linolenic acid accounts for 7 to 10%, linolenic acid accounts for 51%, and oleic acid accounts for 23%.

Camellia oil consists of 1.4% stearic acid, 8.8% palmitic acid, 8.4% linoleic acid and 80.4% oleic acid, while green tea seed oil consists of 3.0% stearic acid and 17.8% palm. Acid, 18.0% linoleic acid and 59.9% oleic acid. Ginseng oil contains 81.09% oleic acid and 15.77% linoleic acid. However, it should be noted that the content of the fatty acid may vary depending on the selected raw materials of soybean, camellia, green tea, ginseng, and the like, and the extraction process used. Undecylenic acid can be obtained by thermal decomposition of castor oil, which can be derived from seed oil, such as grape seed oil, mustard seed oil, and the like.

In order to simultaneously improve the foaming ability and hair smoothness, the content of at least one of the polymers represented by Chemical Formula 1 to Chemical Formula 3 may specifically be 0.01 to 9% by weight based on the total weight of the polymer.

Additionally, cationic surfactants can be used in combination with neutralizing acids. Examples of the neutralizing acid include L-glutamic acid, lactic acid, hydrochloric acid, malic acid, succinic acid, acetic acid, citric acid, EDTA, EDTA-2Na, EDTA-3Na, EDTA-4Na, and combinations thereof, preferably Lactic acid, citric acid and L-glutamic acid.

Preferably, the higher fatty alcohol is present in an amount of from 1 to 15% by weight based on the total weight of the polymer. When the higher fatty alcohol is used in excess, the composition may provide insufficient hair smoothness. On the other hand, too low a level of higher fatty alcohol will make the hair appear sticky and heavy when dry, resulting in hair not being bulky.
