Looking at the components constituting the composition of the present invention in more detail.

[Surfactants]

Essential surfactants among the components of the liquid detergent composition used in the present invention are classified into anionic surfactants, nonionic surfactants and amphoteric surfactants.

The anionic surfactants include alkyl sulfates, alkyl ether sulfates, and alpha olefin sulfonates, which may be used in an amount of 1 to 25 wt%.

Alkyl sulfates are made by reacting higher alcohols with concentrated or anhydrous sulfuric acid to form sulfuric acid esters and neutralizing the resulting sulfuric acid esters with alkalis. The structural formula of the alkyl sulfate thus produced is represented by (R.OSO 3 .M) .

At this time, in the structural formula R is an alkyl group having a carbon distribution of C ₁₂ ~ C ₂₀ , M is sodium, magnesium, ammonium, substituted ammonium and the like. The alkyl sulphate is widely used in dishwashing liquid detergents due to its good water resistance and biodegradability.

The alkyl ether sulfate can be obtained by adding a few moles of oxyethylene to a higher alcohol, making sulfuric acid ester with anhydrous sulfuric acid and neutralizing with alkali.

The structural formula of the alkyl ether sulfate is represented by (R · En · OSO 3 · M) , wherein R is an alkyl group having a carbon distribution of C ₁₂ to C ₂₀ , and E is ethylene oxide (CH ₂ CH ₂ O), where n is It is appropriate to use addition mole number and n having a distribution of about 0 to 5 mole. M is sodium, magnesium, ammonium, substituted ammonium and the like. Alkyl ether sulphate is more water-soluble than alkyl sulphate and has the best hard water resistance among surfactants, so it is most used in liquid detergents because the effect increases when used in combination with alpha olefin sulfonate.

In the alpha olefin sulfonate, a mixture of alkene sulfonic acid and sultone is obtained by sulfonating an alpha olefin synthesized in the petrochemical industry with sulfuric anhydride. When neutralized with alkali, the alkene sulfonic acid becomes sodium alkene sulfonate, part of the sultone is neutralized with sodium alkane disulfonic acid and the remainder becomes hydroxy alkane sulfonic acid sodium. Thus, in the final product, a mixture comprising 64 to 72% of alkene sulfonate, 21 to 26% of hydroxy alkane sulfonate, and 7 to 11% of alkane disulfonate and other byproducts is obtained, which is an alpha olefin sulfonate. . Of these, alkanesulfonate sulfonate is a poor cleaning material, and alkenesulfonic acid sodium salt has a slightly better cleaning power than hydroxy alkanesulfonate sodium, but a proper mixture of these two substances is better than when alone. . The alpha olefin sulfonate has a washing effect, hard water resistance, biodegradability, and less skin irritation than linear alkyl benzene sulfonate, and thus is widely used as an active ingredient of detergent. The structural formula of alpha olefin sulfonate is

It is represented by (R CH = CHCH ₂ SO ₃ Na + R CHOHCH ₂ CH ₂ SO ₃ Na) ,

R has C ₁₀ to C ₁₈ .

In addition to the anionic surfactant, a nonionic surfactant and an amphoteric surfactant may be used as the active ingredient of the detergent.

As the nonionic surfactant, 1 to 5% by weight of fatty acid alkanolamide may be used, and 1 to 5% by weight of alkyl dimethyl amine oxide may be used as the amphoteric surfactant.

Diethanol amide, which combines a higher fatty acid with diethanol amine 1: 1, is insoluble in water, but the 1: 2 combination of fatty acid and diethanol amine is 60-70% alkanolamide and 25-30% diethanolamine. It is used in combination with anionic surfactants in liquid detergents because it is a mixture of 3 to 5% of the amine salts of fatty acids, so it is well soluble in water and increases the foam stability, skin protection, and viscosity of liquid detergents with detergency. In general, the most commonly used fatty acid alkanol amides are coco fatty acid diethanol amides, and the structural formula is represented as follows.

Wherein R = C ₁₀ to C ₁₈ are rh and n = 1 to 3.

In addition, alkyl dimethyl amine oxide helps to maintain the durability and stability of the bubble with the role of alleviating the stimulation of the anion when used in combination with an anionic surfactant, the structural formula is expressed as follows.

R has C ₁₀ to C ₁₈ .
