Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hair cosmetics, and more specifically to birch and/or hair cosmetics.
Or it relates to a hair cosmetic containing a specific extract of rosemary and collagen.

Hair style is one of the most important points in beauty, and various beauty treatments are performed.

For example, methods for giving hair a suitable wave using hair cosmetics include a permanent treatment method using the permanent wave method and a temporary treatment method using setting lotions, hair sprays, etc. However, permanent waving may cause significant damage to the hair, making it impossible to recover, and treatments with setting lotions, hair sprays, etc. may temporarily damage the hair. Since the set is only fixed to the surface, it has the disadvantage that the set easily collapses due to moisture, etc., and neither of these sets were completely satisfactory. Furthermore, these methods tend to make the hair stiff and are not yet satisfactory in terms of the feel of the hair.

In addition, shampoos are used to remove dirt from the hair, but currently commercially available products wash away even the oils necessary for the hair, resulting in dry hair after shampooing and twigs when brushing. There was a drawback that phenomena such as hair loss and hair breakage occurred. Hair rinses, pre-shampoos, and the like have been used to overcome this drawback, but some of these contain oils and fats, which also has the disadvantage of making the hair sticky.

The present inventors conducted various studies on the ingredients of hair cosmetics with excellent properties, and found that specific extracts of birch and/or rosemary and collagen were used in shampoos, conditioners, setting lotions, hair sprays, etc. It has been found that when incorporated into a hair softening sugar such as the following, it is possible to obtain a hair cosmetic that provides an excellent style formation and retention effect and a suitable texture to the hair, and also has good combability.

The present invention provides a hair cosmetic containing a birch and/or rosemary polar solvent extract and collagen.

The birch and/or rosemary extract used in the present invention is obtained by extracting birch and rosemary with a solvent at room temperature or under heat according to a known extraction method. . Examples of the extracting solvent include polar solvents such as lower alcohols such as methanol and ethanol, polar organic solvents such as fluoropylene glycol, 11-butylene glycol, and hydaglycerin, and water, which may be used alone or in combination of two or more. It is used as T.

Each part or all of birch and rosemary can be used as the material to be extracted, but it is preferable to use the bark of birch and the whole plant of rosemary.For extracts of birch and rosemary, commercially available products such as the following are available. can be mentioned.
