Description

Hair conditioning composition

The present invention relates to a hair conditioning composition, and more particularly to a polymer containing a polydimethyl methoxyalkanol and a linear siloxane compound as an active ingredient, and improving the gloss and suppleness of the hair and A smoothing, long-lasting hair conditioning composition, preferably a conditioning composition involving damaged hair.

In general, products that impart hair conditioning (improving hair condition) can be classified into products requiring a cleaning type (rinsing products) and products requiring no cleaning type (a disposable product). Products that need to be cleaned can be divided into hair conditioners, oil eliminants, hair packs, hair masks, hair serums, etc., mainly by containing a quaternary cationic surfactant and a small amount in the emulsifier type. The oyster sauce or synthetic oil, natural oils and other conditioning ingredients impart gloss and smoothness to the hair.

The disposable products can be divided into hair spray, radiance, hair care essence, hair oil, etc., and the hair conditioning effect is imparted by various dosage forms.

The eucalyptus oil used in the disposable hair conditioning composition has various functions depending on its kind or molecular weight, and thus, even if it has the same chemical structure, eucalyptus oil exhibits various use sensibility characteristics. Depending on the molecular weight and viscosity, 矽 shows a variety of forms, from the molecular weight and the lowest viscosity of the volatile form to the molecular weight and the order of increasing viscosity is shown as liquid, viscous liquid, glue (Gum), gel, elastomer and The form of the resin. That is, when the molecular weight of cerium increases, the viscosity also increases.

In the disposable product, in particular, the hair care essence is an excessive amount of the eucalyptus oil dispersed type, and when used on the hair, the gloss and smoothness can be immediately imparted, but there is a stickiness due to excessive eucalyptus oil. The problem of shortcomings such as greasy feeling and sticky feeling of hair.

Further, the conventional hair conditioning composition (dosage form) can impart a glossiness and smoothness to the hair immediately, but has a short lasting force and a feeling of greasy (Oily) on the hands and hair. In order to improve the above-mentioned problems, an excessive amount of eucalyptus oil, a volatile eucalyptus oil, a lubricant for refreshing use, and the like are used, but the effect cannot be sustained for a long time, and causes a problem of stickiness in use and heavy sagging of the hair ( Reference is made to Patent Documents 1 and 2).
