Description

  The present invention relates to a hair cleansing composition having an excellent conditioning effect.

  Due to the influence of recent hair style trends, substances contained in various hair care cosmetics adhere to the hair surface, and various chemical treatments such as hair color, bleach, and perm are added, and the damage state also progresses considerably. It is out. Against this background, there is a growing interest in the function of hair cleaning compositions used daily. Specifically, a shampoo composition has been developed that can clean stains adhering to the hair and has a conditioning effect that does not damage the hair by washing the hair.

The main techniques proposed so far include 1) a method in which a silicone derivative is emulsified and coexisted in a surfactant system, and 2) a method in which a cationic polymer is coexisted in a surfactant system. The former feature is that it can impart excellent smoothness to the dry hair and skin after washing, but the rinsing properties (feeling of fingering and squeaking) during washing are insufficient, and the washing properties and foaming properties are reduced. There are challenges. On the other hand, according to the latter technique, although it is excellent in rinsing properties during washing, there are problems such as poor feeling of dry hair and skin after washing, and deterioration in washing and foaming properties. .
On the other hand, an external preparation composition (patent document 1) containing an acidic heteropolysaccharide obtained from a plant belonging to the genus polianthes L. and a detergent composition containing the acidic heteropolysaccharide and a surfactant (patent) Document 2) and hair cosmetics (Patent Document 3) are known. However, although the foaming property at the time of washing is good, the rinsing property is not as good as the above-mentioned method 2), and the hair that has been dried only by washing is well moisturized, but the conditioner for rinsing off after washing or It does not reveal the moisture retention of dry hair after treatment.

  The object of the present invention is excellent in foaming properties, good fingering during shampooing, no hair entanglement during shampooing and rinsing, and moderate moisturization after drying regardless of the presence or absence of a rinse-off conditioner or treatment treatment In particular, it is intended to provide a hair cleansing composition suitable for hair damaged by chemical treatment such as hair coloring.

  When the present inventors combined use of an acidic heteropolysaccharide obtained from a plant belonging to the polianthes L. group with a specific surfactant and a cationic polymer, rinsing properties during washing, feeling of dry hair after washing It has been found that a cleaning composition having excellent cleaning properties and foaming properties can be obtained.

As a carbon source, 3% saccharose was added. The medium was adjusted to pH 5.7 with 0.1N KOH and then sterilized by autoclaving at 120 ° C. and 12 atm for 15 minutes. Culture was performed at 25 ± 1 ° C. under illumination. Callus was induced from each explant after 30-60 days of culture.
(B) Passage of callus:
Each callus induced in (a) was cultured under the same conditions using the same medium as the induction medium and transplanted to a new medium every 30 days.
(C) Shaking culture:
The callus subcultured for 10 generations or more in (b) was subjected to shaking culture using a liquid medium composed of the same components as the callus culture medium. The amount of the medium was 80 mL per 200 mL Erlenmeyer flask. The callus was inoculated with 2 g of fresh weight, and cultured with shaking at 25 ± 1 ° C. and 120 rpm for 30 days.

Cells were removed from the culture solution of (c) by centrifugation or filtration, and the culture solution was concentrated using a rotary evaporator. About 3 times the amount of ethanol was added to the concentrated culture solution, and the mixture was allowed to stand at 5 ° C. for 24 hours to obtain a precipitate. The precipitate was collected by centrifugation, washed with 70% ethanol, and then water was removed by freeze drying.
By the above method, 1.91 g / L / 30-day extracellular polysaccharide was obtained from tuberose callus. This polysaccharide had the following physical properties.
