Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pearlescent shampoo composition having excellent standing bur properties.

In general, by dispersing and suspending scale-like crystals having pearl-like luster in cosmetics and detergents as a pearl-like luster, the product is adapted to the preferences of users and its value is increased.

However, conventional cosmetics and detergents that have pearl-like luster lose their pearl-like luster over time. That is, the durability of the pearl-like luster is poor, and especially when stored stationary, the pearl-like luster deteriorates significantly. - Generally the visual phenomenon of compositions with pearlescent agents is different from that of the cream state.

In other words, in the cream state, the incident light is diffusely reflected, whereas the pearlescent luster consists of platelet-shaped or rod-shaped crystals.
Incident light is regularly reflected from the front and back surfaces of such crystals. In order for the nacreous agent to exhibit nacreous luster, the nacreous agent must be regularly dispersed in the medium. When left undisturbed for a long time, the pearlescent agent becomes irregularly dispersed in the medium. As a result, the pearlescent luster decreases and eventually disappears completely. Cosmetic cleansers in such a state will once again exhibit a pearl-like luster when shaken, but users tend to judge the appearance of the product in a static state. Therefore, there is a need for a cosmetic detergent that maintains its pearl-like luster even after being left standing for a long time without shaking. As a result of intensive research to solve these problems, the present inventors discovered that a specific anionic surfactant, an ethylene glycol fatty acid ester that is a pearlescent luster, and a specific compound that is a third component. It has been found that the above-mentioned problems can be solved by blending a predetermined amount of.

That is, the Jumpu composition of the present invention has the following general formula (1)
Anionic surfactant represented by 3.0 to 30. The amount of ethylene glycol fatty acid ester represented by the following general formula (■) is 0.1 to 10. % of slag and 0.1 to 10.0 of the compound represented by the following general formula (■)
% by weight.

General formula (1) (wherein, G represents an acid group of a linear olefin sulfonate having an average of 10 to 16 carbon atoms, and M represents an alkali metal or an alkaline earth metal.

) General formula (■): (wherein, X is H or an acyl group having 14 to 24 carbon atoms,
n is an integer of 1 to 3, and R represents an alkyl group having 13 to 23 carbon atoms).

General formula (■) (In the formula, X represents an organic amine residue.

) Hereinafter, each essential component of the present invention will be explained in more detail.

The anionic surfactant represented by the above general formula 0S-M, which is the first essential component of the Jumpu composition of the present invention, is α
- A substance belonging to olefin sulfonates (AOS salts), which is usually obtained by a wax cracking method, an ethylene polymerization method using a Ziegler catalyst, etc., and uses an α-olefin as a raw material having an average carbon number of 10 to 16, It is obtained by holding this in a thin film form and sulfonating it with gaseous anhydrous sulfuric acid diluted with an inert gas, neutralizing it with an alkali metal salt or alkaline earth metal salt such as sodium hydroxide, and hydrolyzing it. .

The obtained product contains 10 to 45% by weight of HOS (hydroxyalkanesulfonate) (however, 2H0S is 0.5 to 45% by weight).
8% by weight, usually 1-5% by weight, (3110S or higher is 5-5% by weight)
This is a mixture containing 55 to 8 weight percent of ANS (alkenyl sulfonate) (44.5 weight percent); and 3 to 15 weight percent of DS (disulfonate).

The amount of anionic surfactant in the Jumpu compositions of the present invention varies somewhat depending on the use of the composition, but generally ranges from 3.0 to 30.0% by weight of the composition, preferably 5.0% by weight. 0-20. Accounts for 1%

The second essential component of the Jumpu composition of the present invention is an ethylene glycol fatty acid ester represented by the above general formula (■), and specific examples thereof include ethylene glycol distearate, ethylene glycol dipalmitate,
and a 5/5 mixture of ethylene glycol monostearate and ethylene glycol distearate. The blending amount is 0.1 to 10% of the total composition. Call volume %, preferably 0.5-5. If the amount of ruts is less than 0.1% by weight, sufficient pearl-like luster and standing burl properties cannot be imparted to the composition, and if the amount of ruts exceeds 1% by weight, the composition tends to gel. Not only that, but also stable pearl-like luster cannot be obtained. As the third essential component of the Jumpu composition of the present invention, compounds represented by the following general formula are preferred.

Chemical name: 1-hydroxy-4-methyl-6-(2,
4,4-trimethylpentyl)- (1-hydro)
-Pyridonemonoethanolamine salt The blending amount of the third essential component is 0.1 to 1% of the total composition as described above.
0. It is slag weight%, preferably 0.3 to 5. Saliva volume%.

If it is less than 0.1% by weight, no improvement in static blistering properties or pearl-like luster is observed, and 10. If the amount exceeds %, the solubility of this substance itself is poor and the pearl-like luster is inhibited.

In addition to the above-mentioned essential components, the following compounds can be added as optional components to the Jumpu composition of the present invention.

That is, appropriate amounts of amphoteric surfactants, nonionic surfactants, fatty acid alkylolamides as foaming power enhancers, ethanol, ethylene glycol and propylene glycol as solubilizers, higher alcohols as performance improvers, chelating agents, These include ultraviolet absorbers, other fragrances, and pigments. The test methods adopted in the test examples shown below are as follows.

1. After placing a stationary bar sample in a glass pin and leaving it stationary (at 25°C) for one month, it was visually compared to a control sample produced under the same conditions as this sample under the light of a box-shaped solar lamp. Compare yo so vs.
Standing bur property was determined based on the following criteria.

Judgment criteria 0: Shows the same pearl-like luster as the control sample immediately after production.

Δ: Pearl-like luster is slightly inferior to that of the control sample immediately after production.
×: Pearl-like luster is considerably inferior to that of the control sample immediately after production. 2 Two syringes without pearlescent needles were fixed with the injection ports facing downward, one filled with 1 ml of the test sample and the other with 1 ml of the control sample, and placed 20 cwt below the injection ports using a black smooth syringe. Simultaneously inject onto the tile board at a speed of 1 m1/sec, 1
After Box 2, the gloss of both samples on the tile board was compared visually and judged according to the following criteria.

Judgment criteria 0: Shows clearly better gloss than the control sample.

Δ: Shows almost the same level of gloss as the control sample. ×: Shows clearly worse gloss than the control sample.

Test Examples Jumpu compositions obtained by blending various anionic surfactants and pearlescent agents with Compound A, which is the third essential component of the present invention, were tested for static blistering properties and pearlescent luster. evaluated.
