Description
Technical Field
The present invention relates to a method of preventing entanglement of hair or fibers.
Background
Hair is damaged by living environment (ultraviolet rays or heat generated by sunlight), daily hair care behavior (friction caused by hair washing or combing), and chemical treatment (dyeing, permanent waving, etc.). If the damaged hairs rub against each other, a large friction force is generated on the surface and entanglement occurs. "tangles of hair" are the cause of all stresses in hair care behavior. The hair cleansing agent such as shampoo is inferior in combing property in an operation of foaming the hair cleansing agent during hair washing, and the hair cleansing agent after hair washing is inferior in combing property during rinsing, and the like, and "hair tangles" are felt.
When a hair cosmetic such as a conditioner or a hair conditioner is used as a method for disentangling hair after shampooing, the hair cosmetic is applied to hair and fused while passing fingers through the tangled portions, thereby disentangling the hair while spreading the lubricating component over the hair surface. In the prior art, cationic surfactants, higher alcohols, silicones, and the like are blended in hair cosmetics such as conditioners, hair conditioners, and the like in order to improve the combing properties or the combing through properties of hair.
Patent document 1 discloses a hair cosmetic composition using a polyether amino group-modified silicone and a cationic surfactant, which can prevent hair from being damaged by entanglement of hair during rinsing by suppressing the dry feeling of hair in a water stream during rinsing and improving softness or smoothness.
Patent document 2 discloses that a hair cosmetic composition comprising an amino-modified silicone, an aminopolyether-modified silicone, a dimethylpolysiloxane having a specific kinematic viscosity range, a specific alkyl cation, and a specific higher alcohol in combination can improve the water retention of hair, improve the combing properties during use, provide a soft and moist finish, and provide a dry and moist feel under low humidity.

Detailed Description
[ method of preventing entanglement of hairs or fibers ]
The method for preventing the entanglement of hair or fiber of the present invention (hereinafter, also simply referred to as "the method of the present invention") is characterized by comprising a step of bringing the hair or fiber into contact with a treatment agent containing or containing the following component (a) and component (B).
(A) An aminopolyether-modified silicone having a polyoxyalkylene structure, which satisfies the following formula (I), and which is contained in an amount of 0.005 to 5 mass%;
0.01≤Si/AO≤1.6(I)
[ in the formula (I), Si represents the number of moles of silicon atoms in the component (A), and AO represents the average number of moles of alkylene oxide added in the component (A). ]
(B) An aqueous medium.
The method of the present invention, by having the above steps, can suppress the occurrence of entanglement in hair or fiber that is likely to cause entanglement, and can spontaneously release entanglement without performing an operation such as passing a hand when entanglement occurs. The phrase "containing the component (A) and the component (B)" also means "comprising the component (A) and the component (B) in combination".
Patent documents 1 and 2 do not disclose suppression and elimination of hair tangles, and particularly do not disclose spontaneous disentanglement of hair by an operation such as passing a hand.
The present invention relates to a method for preventing entanglement of hair or fibers, which can suppress the occurrence of entanglement in hair or fibers that are likely to cause entanglement, and which can spontaneously release entanglement without performing an operation such as passing a hand when entanglement has occurred.
The present inventors have found that: the above problems can be solved by performing a step of bringing hair or fiber into contact with a treatment agent containing or containing a predetermined amount of an aminopolyether-modified silicone having a polyoxyalkylene structure and an aqueous solvent, the treatment agent satisfying predetermined conditions.
According to the method of the present invention, in the hair or fiber in which entanglement is likely to occur, the occurrence of entanglement can be suppressed, and when entanglement occurs, the entanglement can be spontaneously disentangled without performing an operation such as passing a hand. For example, if the method of the present invention is applied to hair, the hair can be dried in a short time because the hair can be prevented from being tangled after being washed and towel-dried, and the finish after drying is also good.
The reason why the above-described effects are produced by the method of the present invention is not clear, but is presumed as follows.
It is considered that, for example, in order to suppress the occurrence of entanglement of hair or fibers, it is important to reduce the frictional force acting between the hair or fibers in a state of spontaneously disentangling even when the entanglement occurs. The present inventors have found that: in order to reduce the frictional force acting on the hair or fibers, it is effective to use a treatment agent containing a specific amount of component (a) which is a water-soluble silicone satisfying predetermined conditions.
For example, when the method of the present invention is applied to hair, the hair is towel-dried in a state where the entanglement of the hair is disentangled, so that the contact area between the hair and the towel is increased, and the moisture of the hair is rapidly absorbed by the towel. In addition, it is considered that, when the hair dryer is dried or naturally dried, the moisture in the hair is rapidly evaporated due to the increase in the contact area of the hair with the air, and therefore, the drying speed of the hair is increased.
The subject to which the method of the present invention is applied is preferably hair from the viewpoint of effectively obtaining the effects of the invention. That is, the treatment agent used in the method of the present invention is preferably a hair treatment agent.
The form of the treatment agent is not particularly limited, and any form such as liquid, foam, paste, cream, solid, powder, etc. may be used depending on the method of bringing the hair or fiber into contact with the treatment agent. When the hair or the fiber is contacted by immersing it in the treatment agent, it is preferably in a liquid state.

By performing this step, the effect of preventing the entanglement of the hair or fiber can be exhibited, and the effect of improving the quick-drying property and the manageability after drying of the treated hair or fiber can be obtained.
In the method of the present invention, at least a part of the hair or fiber may be contacted with the treatment agent. For example, in the case of contacting hair with a treatment agent, at least a part of the hair may be contacted with the treatment agent.
Examples of the method of contacting the hair or fiber with the treatment agent include: a method of applying or spraying a treatment agent to hair or fibers; a method of immersing hair or fiber in a treatment agent, and the like.
In the present invention, it is preferable to contact the hair or the fiber by immersing the hair or the fiber in the treatment agent from the viewpoint of spontaneously disentangling without performing an operation such as passing a hand when the entanglement occurs and the viewpoint of performing the treatment in a short time.
For example, when disentangling the hair, the hair is treated by immersing the hair in the treatment agent and then pulling the hair out of the treatment agent, and the disentangling can be performed without any operation such as passing the hand through the treated hair.
The hair or fiber that comes into contact with the treatment agent may be in a dry state or in a wet state, and the wet state is preferred from the viewpoint of performing the treatment in a short time.

For example, a step of contacting the hair or the fiber with a treatment agent after the hair or the fiber is washed may be performed. Since entanglement is likely to occur in the process of cleaning hair or fibers, the process of contacting the hair or fibers with the treatment agent after cleaning can effectively disentangle the hair or fibers. The hair or fiber can be washed by a known method using a hair detergent or a fiber detergent.
Further, the hair or fiber may be treated with a conditioning agent and then brought into contact with the treatment agent. After the hair or fiber is washed, the hair or fiber may be further treated with a conditioning agent and then brought into contact with the treating agent.
The treatment with the conditioning agent may be carried out by a known method such as applying the conditioning agent to hair or fibers. After treatment with the care agent, the composition may be further rinsed as necessary.
Specific examples of the method of the present invention include the following.
(1) A method of performing a step of washing hair or fibers and then bringing the hair or fibers into contact with a treatment agent;
(2) a method of performing a step of applying a conditioning agent after cleaning hair or fibers and bringing the conditioning agent into contact with a treatment agent without rinsing;

Examples
The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples. In the present example, various measurements and evaluations were performed by the following methods.
(measurement of pH value)
The pH value was measured at 25 ℃ using a pH meter (F-51, manufactured by horiba, Ltd.).
(measurement of Si/AO in component (A))
10mg of the component (A) (aminopolyether-modified silicone 1) used in each example was weighed in a No.3 screw bottle and dried overnight under a nitrogen atmosphere. To the obtained dried product, 1ml of deuterated chloroform (manufactured by Wako pure chemical industries, Ltd.; chloroform-d, 99.8%) was added and dissolved1H-NMR (JH 074504AV400, manufactured by BRUKER JAPAN) calculates the unit ratio of Si/AO from the integrated value of dimethylsilyl groups (6H: δ -0.3 to 0.3ppm) bonded to silicon and the integrated value of Ethylene Oxide (EO) chains (4H: δ 3.3 to 3.9ppm) by the following formula.
(preparation of evaluation Hair Strand)
The hair bundle of untreated Chinese hair having a mass of 20g and a length of 20cm was applied with 20g of the following bleaching agent, left to stand for 30 minutes, and then thoroughly rinsed with warm water at 35 to 40 ℃. This operation was repeated 4 times to produce evaluation hair strands for hair treatment of each example.
[ composition of bleaching agent ]
(measurement of comb load)
The treated tresses obtained in each example were sufficiently rinsed with warm water at 35 to 40 ℃, and then placed in a combing force measuring device ("KOT-0303" manufactured by yudou sperm cell co., ltd.) so that a comb (9 needles each having a diameter of 2mm were linearly arranged at 4mm intervals) penetrated through the uppermost portion of the tresses, and the load (gf) applied when the comb was passed through the hair ends was measured. The load was 200 points calculated for a hair bundle having a length of 20cm, and the total value of the 200 points was defined as "comb load".
If the comb load is less than 15000gf, it means that the effect of disentangling the hair is very high, and if it is 10000gf or less, it means that the entanglement disappears.
(easiness of comb after drying with towel)
The treated hair tresses obtained in each example were thoroughly washed with warm water at 35 to 40 ℃, placed on a towel, and towel-dried so as to cover both sides and rub against each other.
The hair bundle was placed in a combing force measuring device ("KOT-0303" manufactured by Yudu sperm cell Co., Ltd.), the root of the hair bundle was inserted from the left and right sides using 2 brushes, and the brushes were brushed toward the tip of the hair simultaneously, and this operation was repeated 10 times. The maximum load in one stroke was measured, and the number of strokes required until the load became 400gf or less was evaluated. The smaller the number of strokes shown in the table means that the entanglement of hair after towel drying is also smaller, and the hair is combed more easily.
(evaluation of quick drying)
The treated hair tresses obtained in each example were rinsed with warm water at 35 to 40 ℃ for 30 seconds, then dried with hot air from a hair tress (Sobis TYPE315 manufactured by Can Co., Ltd., air volume setting: High) at a distance of 5 to 15cm from the hair tresses while being combed by hand, and the time until the wet hair returned to the dry weight was measured. The shorter the drying time, the higher the quick drying property.
