A process for producing high active detergent particles including reacting the acid form of anionic surfactant with an alkali metal hydroxide solution in a continuous neutralization system, and adding to the system an .alpha.-aminodicarboxylic acid selected from the group consisting of glutamic acid, aspartic acid, aminomalonic acid, aminoadipic acid, and 2-amino-2-methylpentanediotic acid, or their salts. Mono- and disodium glutamate are preferred. |

DETAILED DESCRIPTION What is claimed is: 1.
A process for producing high active detergent particles, comprising the steps of: (a) reacting in a continuous high active neutralization loop, the acid form of an anionic surfactant with an alkali metal hydroxide solution, which is about 30 to 75% by weight of the hydroxide and is present in stoichiometric amount to slight stoichiometric excess, to produce a neutralized product; (b) adding to said continuous high active neutralization loop, during formation of said neutralized product, an .
alpha.
-aminodicarboxylic acid selected from the group consisting of glutamic acid, aspartic acid, aminomalonic acid, aminoadipic acid and 2-amino-2-methyl-pentanedioic acid, or their alkali metal salts; and (c) forming detergent particles from the molten neutralized product of step (b) by cooling and sequentially or concurrently prilling, extruding, granulating or flaking, said particles comprising from about 50 to 90 weight % of the anionic surfactant and from about 0.
2 to 15 weight % of the .
alpha.
-aminodicarboxylic acid salt.
2.
A process according to claim 1, wherein an alkali metal salt of glutamic acid or aspartic acid is added to the neutralization loop.
3.
A process according to claim 3, wherein the alkali metal hydroxide solution is about 62 to 73% by weight of the hydroxide.
4.
A process according to claim 4, wherein rom about 1 to 10 weight % mono- or disodium glutamate is added to the neutralization loop.
5.
A process according to claim 4, wherein the acid form of C.
sub.
12-18 alkyl sulfate is used.
6.
A process according to claim 5, wherein the alkali metal hydroxide solution is sodium hydroxide.
7.
A process according to claim 6, wherein a mixture of the acid form of C.
sub.
12-18 alkyl sulfate and C.
sub.
10-16 linear alkyl benzene sulfate are reacted with the sodium hydroxide so that the final ratio of C.
sub.
12-18 sodium alkyl sulfate to C.
sub.
10-16 sodium linear alkyl benzene sulfonate is between about 75:25 and 96:4.
8.
A process according to claim 7, wherein said mixture is of the acid form of C
