Description

  The present invention relates to a hair cosmetic.

  Examples of hairdressing cosmetics include mist-like hairdressing agents, foamy hairdressing agents, hair gels, hair creams, hair waxes and other hair cosmetics, and mascara and other eyelash cosmetics. In these hairdressing cosmetics, a film-forming resin is blended to impart hairstyling properties. There are various types of film-forming resins. Usually, film-forming resins are stably blended in hairdressing cosmetics by dissolving them in a solvent such as ethanol.

Recently, there is a demand for reducing the use of organic solvents such as ethanol for reasons such as environmental problems.
Patent Document 1 proposes the use of cyclodextrin in an aqueous hair styling composition in which the use of an organic solvent is reduced in order to improve the solubility of the hair styling polymer.

International Publication No. 2002/38113

  However, water-based hair cosmetics have a problem in that when water is applied to the hair, the water penetrates into the hair, which causes dripping (sagging of the hair) and the set is broken. Furthermore, after setting the hair, there is a problem that the setting force cannot be maintained for a long time under high humidity, and the setting force is reduced.

  An object of the present invention is to suppress hair sag after application in a water-based hair cosmetic composition and maintain a setting force for a long time even under high humidity.

The present invention provides a hair cosmetic containing the following components (A) to (D).
(A) Film-forming resin
(B) Cyclodextrin

<Hair sag suppression effect after application>
A hair bundle having a length of 25.5 cm and a weight of 3 g was wetted with water, wound around a rod (tube) having a diameter of 2.2 cm, and naturally dried (left at room temperature for 24 hours or more). After drying, the rod was removed and the apparent length (L) of the hair bundle was measured. Next, 0.6 g of each sample was uniformly applied to this hair bundle using a sprayer with a trigger (PT-200 nozzle diameter: φ0.3 mm) manufactured by Yoshino Kogyo, and then the hair bundle was suspended at room temperature and humidity. After 30 minutes, the apparent length (L ₀ ) of the hair bundle was measured again.
From these measured values, the hair sag suppression rate was determined by the following equation.
Hair sag inhibition rate (%) = [(25.5−L ₀ ) ÷ (25.5−L)] × 100
The closer this value is to 100, the higher the effect of suppressing hair sag.

<Set holding power (under high humidity)>

After drying, the rod was removed and the apparent length (L) of the hair bundle was measured. Next, the hair bundle was hung in a constant temperature and humidity chamber at a temperature of 25 ° C. and a humidity of 90%, taken out after 2 hours, and the apparent length (L ₀ ) of the hair bundle was measured again. From these measured values, the set holding force was obtained by the following equation.
Set holding force (%) = [(26−L ₀ ) ÷ (26−L)] × 100
The closer this value is to 100, the stronger the set holding power.
