Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to hair care compositions, and more particularly to hair care compositions such as shampoos, hair rinses, hair conditioners, hair treatments and the like, which contain an alpha-hydroxymonocarboxylic acid or a salt thereof and a specified aromatic alcohol, and which impart long-lasting softness to the hair. 
     2. Discussion of the Background 
     Conventionally, hair care compositions contain cationic surfactants such as mono- or di- linear long chain alkyl quaternary ammonium salts or mono- or di- branched long chain alkyl quaternary ammonium salts in an attempt to improve the feel of the hair. 
     Such conventional hair care compositions, however, have a drawback in that they impart only insufficient softness to the hair, even though they may provide excellent touch to the hair, or they impart excellent moistness and smoothness to the hair due to their conditioning effects. That is, even though the user may feel softness of the hair when it is wet, such effect is mostly lost when the hair is dried. In order to overcome this drawback, use of oils and fats such as higher alcohols, glycerides and liquid paraffins in combination with cationic surfactants has been practiced. This approach is intended to impart softness to the hair by depositing hydrophobic molecules on the surface of hair fibers to lower the surface tension so that the user feels the hair as softened. Such substances deposited on the surface of hair fibers, however, are removed through contact of the fibers in the everyday life or by physical force such as shampooing, and therefore, a prolonged effect of softness is hardly obtained. Moreover, in the case of solid or stiff hair fibers, it often happens that the hair is difficult to manage in obtaining a desired hairdo, and the conventional approach has not met the users&#39; needs. 
     Recently, in order to enhance the softness of the hair, hair conditioning compositions have been proposed which incorporate a 2-hydroxy aliphatic acid having 6 or more carbon atoms therein as a conditioning component (See, for example, Japanese patent application laid-open (kokai) Nos. 3-48607 and 3-48609). They, however, are not successful in maintaining the softness for a prolonged period. 
     Accordingly, hair care compositions which are capable of imparting moistness and smoothness to the hair and, at the same time, an excellent long-lasting softness even with solid or stiff hair, while providing easy manageability of the hair for a desired hair care still desired. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is one abject of the present invention to provide novel hair care compositions. 
     It is another object of the present invention to provide hair care compositions which impart moistness and smoothness to the hair. 
     It is another object of the present invention to provide hair care composition which impart long-lasting softness to the hair, including solid or stiff hair. 
     It is another object of the present invention to provide hair care compositions which impart good manageability or handling to the hair for obtaining a desired hairdo. 
     These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors&#39; discovery that the use of an alpha-hydroxymonocarboxylic acid or a salt thereof and a specified aromatic alcohol in combination is effective in maintaining softness of the hair for a prolonged period, in particular, is capable of maintaining softness of the hair even in the case of solid or stiff hair, and provides excellent manageability or handling the hair for obtaining a desired hairdo. 
     Accordingly, the present invention provides a hair care composition comprising the following ingredients (a) and (b): 
     (a) an alpha-hydroxymonocarboxylic acid represented by the formula (1): ##STR3## wherein R 1  is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, or a salt thereof; 
     (b) an aromatic alcohol represented by the formula (2): ##STR4## wherein R 2  is a hydrogen atom, a methyl or a methoxy group, X represents a single bond or a linear or branched alkylene or alkenylene group having 1 go 3 carbon atoms, Y is a hydrogen atom or a hydroxyl group, and p and q respectively represent a number from 0 to 5. 
     The present invention also provides a hair care composition comprising the mentioned ingredients (a) and (b), and a surfactant as ingredient (c). 
     The present invention furthermore provides a hair care composition comprising the mentioned ingredients (a) and (b), and an oil or fat as ingredient (d).

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The alpha-hydroxymonocarboxylic acid, which is referred to as ingredient (a), of the present invention is represented by the formula (1). Specific examples of the acid include glycolic acid, lactic acid and alpha-hydroxybutyric acid. Examples of salts of the acid include sodium salts, potassium salts, calcium salts, ammonium salts, triethanolamine salts and organic quaternary ammonium salts. 
     The alpha-hydroxymonocarboxylic acids or salts thereof, which are ingredient (a) may be used singly or in combination of two or more. They are preferably incorporated in amounts from 1 to 20% by weight, particularly, from 1 to 15% by weight (hereinafter may be referred to simply as %) based on the total weight of the composition. 
     The aromatic alcohols, which are referred to as ingredient (b), of the present invention are represented by the formula (2). Preferred aromatic alcohols are those of formula (2) in which q is a number from 0 to 2 and p is a number from 0 to 5. Specific: examples of ingredient (b) include benzyl alcohol, cinnamyl alcohol, phenethyl alcohol, p-anisyl alcohol, p-methylbenzyl alcohol, phenoxyethanol and 2-benzyloxyethanol.

Amounts less than 0.1% will hardly achieve the effect of the invention, whereas, amounts exceeding 30% are not favorable, because the stability of the composition is liable to be lowered.
