Description

How to prevent tangles of hair or fibers

The invention relates to a method for preventing tangles of hair or fibers.

Hair is damaged due to the living environment (ultraviolet rays or heat caused by sunlight), daily hair care actions (friction caused by shampooing or combing), and chemical treatment (coloring, perming, etc.). If the damaged hair rubs against each other, a large frictional force is generated on the surface, causing tangles. "Tangle of hair" becomes the cause of all stress in hair care operations. "Tangle of hair" is felt due to the poor combability during the operation of foaming the shampoo and other hair detergents, and the poor combability during washing of the hair after shampooing. When using hair cosmetics such as conditioner or conditioner as a method to remove the tangles of hair after shampooing, apply the hair cosmetics to the hair on one side and extend the finger to the side of the tangled part Let it adapt, and on the one hand, let the lubricating ingredients spread all over the surface of the hair and remove the tangles of the hair. In the prior art, for the purpose of improving the combability or combability of hair, cationic surfactants, higher alcohols, polysiloxanes, etc. are blended in hair cosmetics such as conditioners or conditioners.

[How to prevent hair or fiber tangles] The method for preventing tangles of hair or fibers of the present invention (hereinafter, also simply referred to as "the method of the present invention") is characterized by having a treatment in which hair or fibers are contained or blended with the following components (A) and (B) Steps of agent contact. (A) Amine polyether modified polysiloxane containing polyoxyalkylene structure satisfying the following formula (I) 0.005 mass% or more and 5 mass% or less 0.01≦Si/AO≦1.6 (I) [In formula (I), Si represents the mole number of silicon atoms in component (A), and AO represents the average addition mole number of oxyalkylene groups in component (A)] (B) Aqueous medium By having the above steps, the method of the present invention can suppress the occurrence of tangles in hairs or fibers that are prone to tangles. In the case of tangles, the hair can be spontaneously released without performing operations such as passing hands. Tangled. In addition, "contains component (A) and component (B)" also means "made up of component (A) and component (B)".

Patent Documents 1 and 2 do not disclose the suppression and elimination of tangles of hair, and in particular, the entanglement of hair is spontaneously released without performing operations such as passing a hand. The present invention relates to a method for preventing tangles of hair or fibers, which is included in hair or fibers that are prone to tangles and can suppress the occurrence of tangles. In the case of tangles, it is not necessary to pass the hand and other operations And spontaneously release the tangle.

The present inventors discovered that by contacting hair or fibers with a treatment agent containing or blending a specific amount of polyoxyalkylene-containing amine-based polyether-modified polysiloxane containing a specific amount that meets specific requirements, and an aqueous solvent Steps to solve the above problems. According to the method of the present invention, the occurrence of entanglement can be suppressed in hairs or fibers that are prone to entanglement, and in the case of entanglement, the entanglement can be released spontaneously without passing through the hands or the like. For example, if the method of the present invention is applied to hair, it can prevent the tangles of the hair after washing and drying with a towel, so the hair can be dried in a short time, and the beatability after drying becomes good.

The reason why the above-mentioned effect is exerted by the method of the present invention is not clear, but it is presumed as follows. It is generally considered that in order to suppress the occurrence of entanglement of hair or fibers, it is also spontaneously released when entanglement occurs, and it is important to reduce the friction force acting on the hair or fibers. The present inventors found that in order to reduce the frictional force acting on hair or fibers, it is effective to use a treatment agent containing a specific amount of the water-soluble polysiloxane component (A) that satisfies specific requirements.

For example, by applying the method of the present invention to hair and drying the towel with the hair tangled, the contact area between the hair and the towel is increased and the moisture of the hair is quickly absorbed by the towel. In addition, it is generally believed that when the hair dryer is dried or naturally dried, the contact area between the hair and the air increases and the moisture in the hair evaporates quickly, so the drying speed of the hair is increased.

From the viewpoint of effectively obtaining the effects of the invention, the object to which the method of the present invention is applied is preferably hair. That is, the treatment agent used in the method of the present invention is preferably a hair treatment agent. The dosage form of the treatment agent is not particularly limited, and depending on the method of contacting the hair or fiber with the treatment agent, for example, any dosage form such as liquid, foam, paste, milk, solid, powder, etc. can be used.

[Example]

Hereinafter, the present invention will be described by examples, but the present invention is not limited to the scope of the examples. In addition, in this example, various measurements and evaluations were performed by the following methods.

(pH measurement) Using a pH meter (F-51, manufactured by Horiba Manufacturing Co., Ltd.), the pH at 25°C was measured.

(Determination of Si/AO in component (A)) Weigh 10 mg of component (A) (amino polyether modified polysiloxane 1) used in each example into No. 3 screw-top bottle under nitrogen Dry overnight in the atmosphere. 1 ml of deuterated chloroform (Wako Pure Chemical Industries, Ltd.: Chloroform-d, 99.8%) was added to the obtained dried product and dissolved, by ¹ H-NMR (BRUKER JAPAN, JH074504 AV400) ，According to the integral value of dimethylsilyl (6H:δ-0.3～0.3 ppm) bonded to silicon, and the integral value of oxyethylene (EO) chain (4H:δ3.3～3.9 ppm), use the following Formula to calculate the Si/AO unit ratio. [Number 1]

(Making of hair bundle for evaluation) Apply 20 g of the following bleach to hair bundles of Chinese untreated hair with a mass of 20 g and a length of 20 cm. After standing for 30 minutes, rinse thoroughly in warm water at 35 to 40°C. This operation was repeated 4 times, and the hair bundle for evaluation used for the hair treatment of each example was produced. [Composition of bleach]ingredient ( quality %) Monoethanolamine 1.5 28% by mass ammonia water 4.0 Ammonium bicarbonate 1.0 35% by mass hydrogen peroxide water 8.2purified water The remaining amount Total 100.0

(Measurement of combing load) After the treated hair bundles obtained in the respective examples were sufficiently rinsed in warm water at 35 to 40°C, they were installed in a combing force measuring device (“KOT-0303” manufactured by Utsunomiya Seiki Co., Ltd.) to make the comb (will The needles with a diameter of 2 mm are arranged linearly at intervals of 4 mm at a distance of 9) and penetrated to the uppermost part of the hair bundle, and the load (gf) applied when passing the comb to the tip of the hair was measured. The load is calculated as 200 points for the hair bundle of 20 cm in length, and the total value of 200 points is set as "comb load". It means that if the combing load is less than 15000 gf, the effect of untangling the hair is very high, and if it is less than 10000 gf, the tangling disappears.

(Ease of combing hair after drying with a towel) After the treated hair bundle obtained in each case was sufficiently rinsed in warm water at 35 to 40°C, it was placed on a towel and wiped dry with a towel so as to cover both sides and rub against each other. Attach the above-mentioned hair bundle to the combing force measuring device ("KOT-0303" manufactured by Utsunomiya Seiki Co., Ltd.), use two brushes to clamp the hair roots of the hair bundle from left and right, and simultaneously brush the brush toward the ends of the hair, repeating this action Do it 10 times. The maximum load in one stroke was measured, and the number of strokes required until 400 gf or less was evaluated. The smaller the number of strokes shown in the table, the less hair tangles after drying with a towel and the easier it is to comb your hair.

(Quick-drying evaluation) After rinsing the treated hair bundles obtained in each example in warm water at 35 to 40°C for 30 seconds, apply a hair dryer (manufactured by Can Co., Ltd.) at a distance of 5 to 15 cm from the hair bundles while manually combing the hair. "Sobis TYPE315", the air volume setting: High) hot air is dried, and the time until the wet hair returns to the dry weight is measured. The shorter the drying time, the higher the quick-drying property.
