Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a fade-resistant surfactant composition containing a tar-based pigment.

BACKGROUND ART In liquid detergents and cosmetic compositions, it is widely practiced to improve the product image and match the tastes of users by coloring the compositions in various colors to give them a beautiful appearance.

However, such coloring compositions often discolor or fade due to heat or light during storage, and in particular, coloring compositions containing nitrogen-containing surfactants and using water-soluble tar pigments as colorants are susceptible to discoloration. The color faded easily, which was a major problem in terms of commercial value. An object of the present invention is to provide a surfactant composition containing a water-soluble tar pigment that is resistant to discoloration and fading.

That is, the present invention provides a colored surfactant composition containing a surfactant and a water-soluble tar dye, which contains 2-bromo-2-nitro-1,3-propanediol or 2-chloro-2-nitro-1,3-propanediol. 0.00
1 to 0.5% by weight and 0.0% sequestering agent.
1 to 1% by weight of a fade-resistant surfactant composition.

The present invention is most effective when applied to compositions containing nitrogen-containing surfactants that exhibit significant discoloration and fading.

Examples of such nitrogen-containing surfactants include amine oxides such as lauryl dimethylamine oxide, alkylolamides such as coconut fatty acid diethanolamide, quaternary ammonium salts such as tallow alkyltrimethylammonium chloride, sodium lauroyl sarcosine, etc. acylated amino acids, betaines such as lauryldimethylaminopropylsulfonic acid, aminodoamine-type amphoteric active agents such as 2-lauryl-N-carboxyethyl-N-hydroxyethylimidazolinium betaine, acylated polypeptides, and polymers such as cationized cellulose. There are many examples of this. Such surfactants are usually used in an amount of 1 to 2% by weight. In addition, water-soluble tar pigments include Red No. 2, No. 3, No. 1, No. 104, No. 105, No. 106, No. 201, No. 213, No. 214, No. 230, No. 231, No. 23? , No. 401, No. 502, No. 503,

Such water-soluble tar pigments are usually contained in an amount of 0.0001 to 0.05% by weight. The anti-fading surfactant composition of the present invention comprises 2-bromo-2-nitro-1,3-propanediol or 2-chloro-2-nitro-1,3-propanediol as a discoloration and fading inhibitor, and a metal ion. and a sequestering agent. 2-bromo-2-nitro-1,3-propanediol or 2-chloro-2-nitro-1,3-propanediol is used in an amount of 0.001 to 0.000% based on the total amount of the composition.
Contains 5% by weight.

Less than 0.001% by weight. Discoloration and fading are not sufficiently prevented, and when the amount exceeds 0.5% by weight, liquid stability deteriorates.

Preferred examples of sequestering agents used in the composition of this invention include citric acid, ethylenediaminetetraacetic acid ED
TAL tripolyphosphate, hexameta. Mention may be made of phosphoric acid, dihydroxyethylglycine tartaric acid, gluconic acid, 1-hydroxyethane-1,1-niphosphoric acid, nitrilotriacetic acid, and salts thereof. Among these, particularly preferred are citric acid, ethylenediaminetetraacetic acid, and salts thereof. These metal ion sequestering agents are contained in an amount of 0.01 to 1% by weight based on the total amount of the composition. 0.0
If it is less than 1% by weight, discoloration and fading will not be sufficiently prevented;
If it exceeds % by weight, the liquid stability will deteriorate.

When an ultraviolet absorber is added to the composition of the present invention described above,
The effect of preventing discoloration and fading is enhanced. Preferred ultraviolet absorbers include 2,4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone, and 2-hydroxybenzophenone.
-Hydroxy-4-n-octoxybenzophenone, 2
-(3″,5-di-t-butyl-2-hydroxyphenyl)-benztriazole, 2-(2″-hydroxy-3″,5″-di-t-butylphenyl)-5-chlorobenzunotriazole, 2- (2″-hydroxy-5″

Such UV absorbers are contained in an amount of 0.01 to 1% by weight based on the total amount of the composition. If it is less than 0.01% by weight, the effect of preventing discoloration and fading will not be enhanced, and if it exceeds 1% by weight, the liquid stability will deteriorate.

The surfactant composition of the present invention is used as a liquid detergent, a cosmetic, etc., and in addition to the above-mentioned ingredients, the surfactant composition may optionally contain hydrodope, inorganic salt, Organic acids, fragrances, colorants, antioxidants, preservatives,
Ultraviolet absorbers, bur agents, thickeners, foaming agents, humectants, oils, and the like can be added as necessary.

Next, Examples and Comparative Examples of the present invention will be shown to specifically explain the effects of the present invention.

The evaluation was performed after storage at 45°C in a polyvinyl chloride bottle containing 0.2% of 2-(2'-hydroxy-5'-methyl-phenyl)-benzotriazole, or after storage outdoors and irradiation with a UV dose of 600 ranks. After a few days (measured with Suga Test Instruments integrated illumination meter PH-11P-2UT), the degree of discoloration was visually observed and compared with the sample stored in the refrigerator.
Evaluation was made on a four-level scale. ◎...Almost no change 0...Slight change Δ...Change ×...Significant change Test example 1 A mark of 0 or higher is desirable in terms of commercial value C11-15 oxo method synthetic alcohol 3 mole ethoxy sulfate ester 5 parts by weight of sodium salt, 5 parts by weight of sodium Cl4 alpha olefin sulfonate, 5 parts by weight of lauryldimethylamine oxide, Red No. 106 0.000

, 3-propanediol and a sequestering agent were mixed in the amounts shown in Table 1, and the color changes after storage at 45°C and F for 3 months were examined.

The compositions in Table 1 are given in % by weight. From Table 1,
In Examples 1 to 7, in which both 2-bromo-2-nitro-1,3-propanediol and a sequestering agent were blended, the color change was small, whereas in Comparative Examples 1 to 7, in which either or both were not blended. It can be seen that 4 has a large color change.

Furthermore, it can be seen that disodium EDTA and citric acid exhibit particularly excellent effects as metal ion sequestering agents.
Test Example 2 A surfactant composition having the composition shown in Table 2 was prepared,
Changes in color were examined after storage at 45°C for 3 months.

The results are shown in the same table. In Table 2, the compositions are expressed in % by weight. In addition, in Examples 8 to 11 and Comparative Examples 5 to 8, PH

O) was prepared and the color change was examined after storage at 45°C for 6 months.

In addition, the same composition was stored outdoors and the color change after absorbing 600-Rankley ultraviolet rays was examined. The results are shown in the same table. In the table, the composition is shown in weight %. From Table 3, the effect of preventing discoloration due to outdoor sunlight irradiation can be further enhanced by using 4-methoxybenzophenone, an ultraviolet absorber, in combination with 2-bromo-2-nitro-1,3-propanediol and citric acid. I understand that.
