Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to pearlescent agents, particularly pearlescent agents suitable for being incorporated into cationic surfactant systems such as hair rinses, hair treatment agents, and fabric softeners.

Traditionally, pearlescent agents have been used primarily in anionic surfactant formulations such as shampoos, but not in cationic surfactant systems such as hair rinses, hair treatment agents, and clothing softeners. The reason for this is that it has been difficult to obtain stable pearlescent luster in formulations such as hair rinses.

The present inventor has conducted repeated research to develop a substance that is stable and easily imparts pearlescent luster regardless of the type and concentration of the cationic activator in a system containing the cationic activator. By crystallizing an alkanediol diester in a cationic surfactant, a composition that provides a stable pearlescent luster has been discovered, and the present invention has been completed.

That is, the pearl luster imparting agent of the present invention has the formula (1)% formula% (wherein R and R' each represent an alkyl group having 12 to 24 carbon atoms, and n is an integer of 1 to 10.) 3 to 40% by weight of alkanediol diester represented by formula 2 (
2) (In the formula, - of R to R4 represents an alkyl group or hydroxyalkyl group having 8 to 24 carbon atoms in the double alkyl group, and the remainder is an alkyl group with 1 to 24 carbon atoms in the alkyl group.
-3 represents an alkyl group, a hydroxyalkyl group, or a benzine group.

X represents a halogen atom, an alkyl sulfate group having 1 to 2 carbon atoms, or an organic acid group. ), and 3 to 15% of quaternary ammonium salts represented by formula (3)% (31 (wherein, R is an alkyl group having 8 to 24 carbon atoms, n is 0 to 2

．． It is a pearlescent agent containing 1 to 5% by weight.

In the pearl luster imparting agent of the present invention, the amount of the first component represented by formula (1) % formula % (1) (where R, R' and n are the same as above) is The amount is 5 to 40% by weight, preferably 10 to 30% by weight based on the total brightness imparting agent.

If it is less than 3% by weight, it will not crystallize and therefore will not have pearlescent luster. On the other hand, if it exceeds 40% by weight, the viscosity is too high, making it difficult to mix and disperse into a cationic surfactant system such as a rinse, which is not preferable.

Representative examples of the first component include the following compounds, which can be used alone or in combination: monoethylene glycol distearate,
Monoethylene glycol cyhalmitate, mixed acid diester of stearic acid and palmitic acid of monoethylene glycol, triethylene glycol distearate.

Mixed acid diesters of stearic acid and palmitic acid of ethylene glycol, etc.

In the pearlescent agent of the present invention, formula 12) (wherein R1
-)'4 + 'lj- and X are the same as above. The amount of the second component represented by ) is 3 to 15% by weight, preferably 3 to 10% by weight, based on the total pearlescent agent.

If it is less than 3% by weight, crystallization of the first component does not proceed or is slow, while if it exceeds 15% by weight, it results in a gel state,
It is not preferred because it has poor dispersibility in cationic surfactant systems.

Typical examples of the second component include the following compounds, which can be used alone or in combination: cetyltrimethylammonium chloride, cetyltrimethylammonium bromide, stearyltrimethylammonium chloride. , behenyltrimethylammonium chloride, stearyldimethylbenzylammonium chlorite, behenyldimethylbenzylammonium chlorite.

Stearylpentaethoxyammonium chloride, distearyldimethylammonium methylsulfonate, stearylpentaethoxyammonium lactate, etc.

In the pearlescent agent of the present invention, the amount of the third component represented by formula (3)% formula % (3) (wherein R and n are as described above) is determined based on the total pearlescent agent. Against 01~
5% by weight, preferably a3-3% by weight.

This is because if it is less than 0.1% by weight, the emulsifying power of the second essential component is insufficient, while if it exceeds 5% by weight, it may have an adverse effect on the final preparation such as a hair rinse.

Representative examples of this third component include the following compounds, which may be used alone or in combination: nilauryl alcohol, polyoxyethylene lauryl ether, myristyl alcohol, polyoxy Ethylene myristyl ether, palmityl alcohol.

Pholoxyethylene pal ξ tyl ether, stearyl alcohol, polyoxyethylene stearyl ether, oleyl alcohol, holyl oxyethylene oleyl ether.

The pearl luster imparting agent of the present invention contains the above-mentioned first, second and third components, and prevents the gelation of the pearl luster imparting agent, and also allows the pearl luster imparting agent to be used in hair rinses, etc. In order to improve the dispersibility upon addition of the formula (4) (% formula%) (4) (where R is a polyhydric alcohol having 2 to 4 hydroxyl groups from which hydroxyl groups have been removed), a fourth component is added. a polyhydric alcohol condensate represented by (representing a residue, a represents an integer of 1 to 3) and a carbon number of 8 to 22
It is preferable to contain 0 to 11% of esters with fatty acids. Examples of this fourth component include the following compounds, which can be used alone or in combination: di-glyceryl monooleate, diglyceryl sesquioleate, diglyceryl dioleate. ,
Diglyceryl instearate, diglyceryl sesquiisostearate.

Diglyceryl diinstearate etc.

The pearl luster imparting agent of the present invention may contain 0 to 6% by weight of inorganic salts as a fifth component in addition to the above-mentioned first, second, and third components (or even the fourth component) K. preferable.

The inorganic salts are effective for controlling the viscosity of the pearlescent agent. As inorganic salts, mention may be made, for example, of the following compounds, which can be used alone or in mixtures: sodium chloride.

Potassium chloride, ammonium chloride, sodium sulfate, etc.

The pearl luster imparting agent contains water in the pond of each of the above ingredients, and the total amount is 1
00% by weight. In addition, if necessary, the pearlescent agent of the present invention may contain conventional additives such as fragrances, coloring agents, medicinal ingredients, etc., to the extent that they do not interfere with imparting pearlescent luster.

The pearlescent agent of the present invention is a hair rinse.

Hair treatment agents, clothing softeners, etc.

It is particularly suitable for adding to cationic surfactant systems to impart pearlescent luster. However, they can also be used in anionic surfactant systems, such as hair shampoos containing cationic surfactants. In addition, the pearl luster imparting agent of the present invention has a content of the first component in the entire surfactant system to which pearl luster is imparted by adding it.
Preferably, it is added in an amount of 5% by weight.

Hereinafter, the present invention will be explained in more detail with reference to Examples. Percentage values in each example refer to percentages by weight.

Examples 1 to 13 A mixture consisting of the first to fifth components shown in the table below and the remainder water was heated until each component was dissolved, and then slowly cooled while stirring. The presence or absence of pearlescent luster in the mixture after cooling was determined visually. Further, the dispersibility in water was determined by adding 5f of each of the completed mixtures to 100 cc of water at 25°C, stirring, and visually determining the dispersibility.

Temperature stability was determined by repeatedly cooling and heating the mixture at -5°C and +45°C every 24 hours for 30 days, and visually observing the stability of the mixture.
