2. Description of the Related Art
Detergent such as shampoo, soap, body shampoo, kitchen detergent and laundry detergent is required to be higher foam than high detergency.
Conventionally, A foaming surfactant in these detergents anionic surfactants, nonionic surfactants, amphoteric surfactants, dipolar-ionic surfactants, semipolar surfactants and cationic surfactants are used in the main component.
If used alone as a main component of these surfactants, in general, the speed of lathering, foam volume is not sufficient.
In recent years, such as fatty acid monoethanolamides (Japanese unexamined Patent Publication No11-080785(JP-11-080785-A)), mixture of polyoxypropylene fatty acid alkanolamides (Japanese unexamined Patent Publication No09-020740(JP-09-020740-A)), hydroxyalkylated polyhydric alcohol ether compound (Japanese unexamined Patent Publication No2003-096435(JP-2003-096435-A)) and glycerylether (Japanese unexamined Patent Publication No2001-107097 (JP-2001-107097-A)) in addition to the fatty acid diethanolamide and the alkylamine oxide which has been widely used.
However, even if these detergent composition, detergency, foam volume and foam quality is imploved, the speed of lathering is not satisfactory.
The object of the present invention is to provide foam booster which the speed of lathering is excellent by using together with foaming surfactant such as anionic surfactants, nonionic surfactants, amphoteric surfactants, dipolar-ionic surfactants, semipolar surfactants and cationic surfactants, a detergent composition containing the same.
The inventors of the present invention have made extensive research to develop a new foam booster comparable to the conventional fatty acid alkanolamide compounds, and as a result, found that aliphatic amine alkylene oxide adduct can be used as a foam booster having the ability to improve the speed of lathering.
This is, the present invention is a foam booster comprises an aliphatic amine alkylene oxide adduct represented by the general formula (I):
[whrein R1 is an alkyl group having 6 to 10 carbon atoms, A1O and A2O represent an oxyethylene group and/or an oxypropylene group and independently from each other, m and n are each independently a whole number more than 0, with 1≦m+n≦2.]
And it also includes matters relating to the production method of aliphatic amine alkylene oxide adduct.
For more information, a method for producing the foam booster is characterized by additional reacted in 1≦(A2+A3)≦2, wherein A2 and A3 represent respectively molar of A2 component and molar of A3 component as to 1 molar A1 component. In addition, A1, A2, A3 are shown below.
(A1) An aliphatic primary amine which linear or divergent having 6 to 10 carbon atoms
(A2)ethylene oxide
(A3)propylene oxide
The foam booster of the present invention can achieve the speed of lathering unprecedented, by mixing with the surfactant.
The foam booster of the present invention, is composed of an aliphatic amine alkylene oxide adduct represented by the general formula (I).
Further, the compounds is obtained by reacting in the range of 1 mol to 2 moles of ethylene oxide and propylene oxide to an aliphatic primary amine which linear or divergent having 6 to 10 carbon atoms.
If when the aliphatic primary amine is longer than 10 carbon atoms, it is undesirable because the speed of lathering and foamability effect do not appear.
And when the aliphatic primary amine is shorter than 6 carbon atoms, it is undesirable because foamability effect do not appear.
The foam booster of the present invention can be obtained by condensation of (A2) mol and/or (A3) mol of ethylene oxide and/or propylene oxide per 1 mol of an aliphatic primary amine used as a raw material.
At this time, the additional number of moles of alkylene oxide, it is important to react in the range of 1≦(A2+A3)≦2 for primary aliphatic amine as a raw material.
Furthermore, addition reacting in the range of 1≦(A2+A3)≦1.9 is more preferable.
If when the sum of A2+A3 is less than 1, it colored with time derived from raw materials, and amine odor occurred.
And when the sum of A2+A3 is more than 2, the product is colored, that is a problem with the quality of product. In addition, undesirable effects of the invention is reduced the speed of foaming significantly.
