JPH04279513A - Shampoo composition - Google Patents

Abstract

PURPOSE:To provide a shampoo composition giving excellent feeling in use, having excellent storage stability, exhibiting excellent frothing power in shampooing to give quickly defoamable bubbles and facilitate the rinsing of the hair, and capable of imparting conditioning effect simultaneous to shampooing to give treated hair having beautiful appearance. CONSTITUTION:The objective shampoo composition containing a silicone substance in a state separated from the detergent of the shampoo can be produced by encapsulating a silicone substance, preferably a silicone derivative of formula I or II in a capsule of 1-3mmphi and dispersing the capsules in a shampoo agent. Since the silicone substance is separated from the detergent of the shampoo, the composition has excellent storage stability. The capsule is broken by friction in shampooing to release the silicone and, accordingly, the composition gives high foaming tendency until the capsule is broken and, after the breakage of the capsule, the bubble is quickly eliminated by the defoaming action of the silicone to facilitate the rinsing of the hair. Furthermore, the silicone imparts the hair with conditioning effect (softness, combing smoothness, flexibility, etc.) to improve the feeling in use and suppress the loosening of hair after drying.

Description

[Detailed description of the invention]

0001

FIELD OF THE INVENTION The present invention relates to the stability of silicone oils in shampoos, as well as to shampoo compositions with antifoaming and good conditioning properties.

0002

[Prior Art] Traditionally, hair has been generally washed with shampoo and conditioned with a rinse.
While there are many consumer requests for shampoo, in recent years women have entered the workforce and both women and men have placed importance on cleanliness, and washing their hair before going out in the morning has become popular, and shampoo is one way to shorten the hair washing time. -A shampoo with a rinse that can be used for rinsing and rinsing at the same time has been developed and is commercially available. However, the current situation is that shampoos containing conditioners have weak cleaning effects and insufficient conditioning effects. Conditioning effects are an essential condition when hair is washed, as hair is subjected to abuse due to external conditions such as ultraviolet rays and perms. Furthermore, in Japanese customs, there is a misconception that the better the lather, the higher the cleaning effect. Due to this excessive lathering, many shampoos have difficulty in lathering afterwards. This causes hair washing to take longer and more water to be used. In addition, commercially available shampoo products are uniform in appearance and are only differentiated by color, container, and scent, making them more interesting.

0003

SUMMARY OF THE INVENTION An object of the present invention is to provide a shampoo containing capsules in order to overcome the drawbacks seen in the prior art. Without degrading the effervescence of time,
Improves foam removal during rinsing. (2) It has good hair conditioning, giving the hair flexibility, ease of combing, suppleness, etc., and also prevents split ends. (3)
To arouse consumers' desire to purchase and wash their hair with an interesting appearance.

0004

[Means for Solving the Problems] As a result of repeated research to achieve the above object, the present inventor has discovered that silicone oil can be
By enclosing the silicone substance in a ~3 mm diameter capsule and dispersing it in the shampoo agent, the silicone substance is isolated from the shampoo agent, resulting in excellent storage stability, a beautiful appearance, and the retention of the silicone when washing hair. A shampoo containing a capsule-type antifoaming agent was obtained which sufficiently exhibited an antifoaming effect and a good conditioning effect.

[0005] Raw materials used for the capsule film include, for example, gelatin, sodium alginate, agar, carrageenan, etc., and the color can be adjusted as desired. The manufacturing method may be a known method such as the rotary method or JP-A-1-193216.
or the alginic acid method described in JP-A No. 55-39710 and JP-B No. 62-5583. There are no particular restrictions on the type of silicone, but in particular the silicones (1) and (2) shown below.
Preferred are derivatives.

(1) Methylpolysiloxane

[Chemical formula 1] Specifically, the compound of (1) is Torray silicone (
There is one commercially available from Co., Ltd. under the trade name SH200.

(2) Methylphenylpolysiloxane

[Chemical formula 2] Specifically, the compound of (2) is Torray silicone (
There are products commercially available under the trade names SH510, SH550, and SH710 from
-60°C to 250°C), SH550 is for medium and high temperatures (-40°C
℃~240℃), SH710 is for high temperature use (-18℃~26℃)
0°C) and the physical properties are somewhat different.

In the shampoo composition of the present invention, the capsules are destroyed by friction during hair washing and the silicone is released, so the shampoo composition foams well until the capsules are destroyed, and after the capsules are destroyed, the silicone is released.
The anti-foaming action of the water bottle removes bubbles quickly and makes rinsing easy. In addition, silicone imparts conditioning effects to the hair (softness, ease of combing, suppleness, etc.), making the shampoo in capsules comfortable to use and preventing dry hair from becoming dry. I found out what I can get.

EXAMPLES Next, the present invention will be explained in more detail with reference to examples. Example 1. Silicone-encapsulated capsules were dispersed in a commercially available transparent shampoo, placed in a glass container, and stored in a constant temperature bath at 40° C. for 16 weeks to confirm stability. Further, three cycles of -20°C for 1 day and then 40°C for 1 day were performed and similarly confirmed, and both were found to be stable with no change in appearance. Example 2. 100 milligrams of silicone-encapsulated capsules were dispersed in 8 grams of shampoo, which was used as the amount for one use, and 10 women with long hair (A to J) used it every other day for a week and evaluated it. . As a control, the shampoo used above alone and a commercially available shampoo with rinse were similarly used for comparison. The results of the sensory evaluation are shown in Table 1 below. In Table 1, ++ means very good, + means good, ± means average, - means bad, and -- means very bad.

0010

[Table 1]

As is clear from the results in Table 1, the capsule shampoo of the present invention was superior to other control products in all aspects such as foaming, foam breakage, and suppleness.

0012

[Effects of the Invention] As explained above, the capsule shampoo of the present invention has excellent storage stability by encapsulating silicone, foams well when washing hair, and quickly runs out of foam and is easy to rinse. Easy to do. Moreover, it has a conditioning effect at the same time as washing the hair, has a beautiful appearance, and has an excellent feeling of use that attracts the interest of consumers.
