Description

Additive for high concentration anionic surfactants {ADDITIVES FOR HIGH-CONCENTRATION ANIONIC SURFACTANTS}

The present invention relates to an additive for high concentration anionic surfactant and an anionic surfactant composition containing the same.

Alkyl ether sulfates obtained by the sulfation of alkylene oxide adducts (oxyalkylene alkyl ethers) of higher alcohols have less irritation to the skin and are used as liquid detergents such as anionic surfactants for shampoos, medicines and cosmetics. It is widely used.

Alkylethersulfates are usually prepared as a paste or liquid composition containing water, the active ingredient concentration of which is as high as possible in consideration of handling, efficiency of manufacturing apparatus, cost of product transport, fluidity, and the like. It is preferable to set. The fluidity of the alkyl ether sulfate composition is affected by the chemical structure of the raw material higher alcohol, the number of repetitions of oxyalkylene units, the amount of unreacted oxyalkylene alkyl ether, the content of by-product alkylene ether glycol and inorganic salts, and the like. Also in the active ingredient concentration, the fluidity is remarkably different. For example, it is also known that fluidity | liquidity may fall to such an extent that extraction of the alkyl ether sulfate composition from a drum can become difficult. Therefore, if the fluidity of a composition containing a high concentration thereof can be improved without lowering the concentration of the alkyl ether sulfate, the production efficiency is improved and the transportation cost is reduced, which is industrially advantageous.

As means for improving the fluidity of the alkyl ether sulfate composition, for example, (1) a composition containing an alkyl ether sulfate and a salt of an alkylene ether glycol sulfate ester obtained from polyalkylene ether glycol as a viscosity modifier (example For example, JP-A-56-36596) and (2) 0.1-25 mass% of polyethyleneglycol with an average molecular weight of 300-6000 with respect to the sulfur oxide at the time of neutralization process of oxyalkylene alkyl ether sulfate ester, or after neutralization. Low viscosity surfactants (for example, Unexamined-Japanese-Patent No. 50-116383) etc. which are obtained by adding in the ratio of are disclosed.

However, in the composition of (1) and the low-viscosity surfactant of (2), although an effect of improving fluidity to some extent is seen, it is not satisfactory enough, and the alkyl ether sulfate composition and such alkyl ether exhibiting higher fluidity. There has been a desire to develop a glidant capable of providing sulfate compositions.
