AQUEOUS, STABLE, ABLE TO PUMPING SUSPENSION FOR DETERGENT PREPARING Russian patent published in 1996 - IPC

FIELD: detergents. SUBSTANCE: aqueous suspension has, wt.-%: silicate of the formula (I) (I) 0,5-80 0.5-80; (Kat 2/n O)_xMe₂O₃ (SiO₂)_y, where Kat - cation at valency - n; x = 0.7-1.5; Me - B or Al; y = 0.8-6, and dispersers based on the mixture of two polyesters of the formula (II) (II) R(OCH₂CH₂)_nOH, where R - C₁₀-C₁₅-alkyl, n = 3-5.25 moles of hydroxyethyl groups at the first polyester and n = 5.5-7.0 moles of hydroxyethyl group at the second polyester, and, additionally, 5-15 wt.-% polyethylene glycol at an average molecular mass 200-2000 0.5-6, and water - up to 100. Zeolite is used as silicate in suspension content. Disperser involves a mixture of two alcohol polyesters, preferable, one polyester containing 3-5.25 mole of hydroxyethyl groups showing cloud point 56-68.5 degrees and R - C₁₀-C₁₅-alkyl. The second polyester has preferably 5.75-6.5 moles of hydroxyethyl groups, cloud point is 70.6-80 degrees and R - C₁₀-C₁₅-alkyl. Preferably to use the first and the second alcohol polyesters in disperser at the mass ratio from (9:1) to (1:9). Suspension is used for production of detergents and cleansing agents. EFFECT: enhanced effectiveness of suspension. 4 cl, 4 tbl
