JPS6056121B2 - liquid hair conditioner composition - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel liquid hair styling composition, and an object thereof is to provide a liquid hair styling composition that has an excellent hair styling effect and is extremely less sticky when used. There is something to do.

Conventionally, liquid hair styling products have a molecular weight of 1000 to 3000.
Polyalkylene oxides, polyalkylene oxide alkyl ethers, or phosphoric acid esters thereof are used, and their adhesiveness is the source of their hair styling power.

These polyalkylene oxide derivatives can be obtained with various viscosities depending on the degree of polymerization or molecular structure, so by selecting them appropriately, it is possible to easily obtain products that meet the user's preferences. Liquid hair styling products that use hair styling products now account for the majority of current hair styling products for men. However, when using a polyalkylene oxide derivative as a hair styling agent component, if you expect strong hair styling power, you must use a highly sticky product, but if you use a highly adhesive product, the properties of the hair styling product may be affected. It has the disadvantage of increasing stickiness, which is the most disliked among them.

Therefore, the present inventors conducted extensive research in order to obtain a liquid hair styling composition that has excellent hair styling ability and is less sticky.

The present inventors conducted a detailed study on where in the hair styling process the stickiness of liquid hair styling products is felt, and found that during hair styling, the hair styling product is applied to the hair, and the hair styling product is spread out by massage or hands. It has been found that there is almost no perceived stickiness after the hair conditioner dries. Typical commercially available products A and B were tested for stickiness after the hair styling product was applied to the hair and until it dried, in relation to the moisture content in the residue. The resulting gate is as shown in Figure 1. In other words, after the ethyl alcohol in the hair conditioner evaporates, polyalkylene oxide derivatives, surfactants, etc. and water remain on the hair, but in the case of A, as the water evaporates afterwards, the hair becomes uniformly gel-like and sticky. do. On the other hand, in case B, when the amount of water relative to the polyalkylene oxide derivative is below a certain level, when mechanical force such as massage is applied, it becomes a W/0 emulsified state, which also increases stickiness. However, the main component is a polyalkylene oxide represented by the general formula (1) or its alkyl ether (component A), and a phosphate ester derivative (i.e., an ionic surfactant represented by the general formula (■)) (
The present invention was completed based on the discovery that a product containing component B) and a nonionic surfactant represented by the general formula (■) (component C) in a fixed ratio exhibits extremely little stickiness during the drying process.

1 component A: the following general formula (1), (wherein Rl and R2 are the same or different and represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms, n is an integer of 20 to 50, and m is 0 to (representing an integer of 10) or its alkyl ether.

Two components B: the following general formula (■), [wherein R3 is a hydrogen atom or an alkyl group having 1 to 18 carbon atoms, k is an integer of 0 to 50, e is an integer of 0 to 50, and M is a carbon alkanolamine, alkylamine, sodium or potassium of number 2 or 3, R4 is hydroxyl group, 0 (t)
A phosphoric acid ester derivative represented by M(+) or, differently, represents a hydrogen atom or a methyl group.

3 component C: the following general formula (■) (wherein, R represents a secondary alkyl group having 8 to 18 carbon atoms, j
is an integer from 5 to 30).

That is, the present invention provides a liquid hair styling composition containing 10 to 30% by weight of component A (hereinafter simply referred to as %), 1 to 30% of component B, and 1 to 30% of component C, by weight. It is something that provides something.

Among the components A of the present invention, preferable ones include R2 in the formula (1)
is represented by a hydrogen atom in the following general formula (■) (where Rl
, n, and m are the same as above), and particularly preferred are those where m is an integer of 0 to 5.

Preferred components of component B include the following general formula (■), (wherein R″3 is an alkyl group having 4 to 18 carbon atoms, R″,
is hydroxyl group, R:-0SakiCH2CH-σX7(a)H2C
H2O Masu Ashimata 410(-)M<+), k″ is 20~4
is an integer of 0, e'' is an integer of 2 to 5, and M is the same as above).

In addition, as component C, in the formula (■), R5 has 8 to 1 carbon atoms.
Those represented by a secondary alkyl group of 5 are preferred.

The amount of component B blended must be 1 to 30% of component A; if it is less than 1%, the O/W type emulsification state necessary to prevent stickiness cannot be obtained, and if it exceeds 30%. Due to solubilization, the entire product becomes gel-like, and stickiness cannot be prevented.

The blending amount of component C is preferably 1 to 30% of component A, and 1 to 30% of component A.
If it is less than 30%, a 0/W type emulsion cannot be obtained, and if it exceeds 30%, it tends to help solubilization and become a gel. Although the objective can be achieved by blending component B and component C within the above range, it is particularly preferable to blend both components in an amount of 3 to 10% of A.
The liquid hair styling composition of the present invention is produced by adding and dissolving the above three components in a base such as ethyl alcohol or water.
%.

Furthermore, in addition to the above three components, the composition may contain humectants such as propylene glycol, glycerin, and sorbitol, hair styling enhancers such as polyvinyl alcohol and polyvinylpyrrolidone, pigments, fragrances, and optional ingredients. solubilizer,
Known components such as other types of surfactants can be optionally blended. The liquid hair styling composition 5 of the present invention obtained as described above has extremely low stickiness, for example, Example J2.
The results of examining the stickiness of the product obtained using Formulation 1 are as shown by curve C in FIG. 1, and the stickiness behavior is completely different from that of products A and B. In other words, the feature of the liquid hair styling composition of the present invention is that even when the composition dries to a ratio of non-volatile components (particularly component A) to water of approximately 1:0.1, it has very low stickiness and no stickiness. I can hardly feel it.

In addition, during normal hair styling, the hands touch the hair at a ratio of approximately 1:0.2, so that there is virtually no stickiness during hair styling. Also, the ratio is 1:0.1
If it contains more water, it is in an O/W emulsion state, so
There is almost no greasy feeling. As described above, the liquid hair styling composition of the present invention is extremely advantageous since it does not leave greasiness or stickiness when hair is styled, so it can increase the tackiness when drying. Next, an example will be given and explained.

Example 1 A liquid hair styling composition containing various emulsifiers was produced according to the following formulation, and its stability and stickiness (stickiness) were evaluated.

As an evaluation method, various liquid hair styling compositions were tested at -5°C, 2
The stability of the blend by observing separation and turbidity at 0C and 40℃, the stability of the emulsified state of the hair styling agent when drying, and the confusion in the hands when drying to a non-volatile content: moisture ratio of 1:0.2. The tackiness to touch was observed.

The test results are shown in Tables 1 and 2. In Table 2, the nonionic surfactant is 1.5% and the ionic surfactant is 1.5%.
An emulsifier consisting of % was used. (Formulation) Monobutyl ether of polypropylene oxide (molecular weight = 2700) 20.0% propylene glycol 3.0 ethyl alcohol 50.0 emulsifier
3.0 Fragrance 1.0 Ion-exchanged water 23.0 (Production method) After weighing each component, stir at room temperature to uniformly dissolve.

As can be seen from Tables 1 and 2, only the combination of a phosphoric acid ester derivative and an ethylene oxide adduct of a secondary alcohol can provide a hair styling composition with excellent stability and adhesiveness.

Example 2 A liquid hair styling composition was produced in the same manner as in Example 1 using the following formulation.

No stickiness was observed in any of these during use.
