Abstract

The invention discloses a defoaming agent for a liquid detergent. The defoaming agent comprises a component A1, a component A2, a component B, a component C and a component D, wherein the component A1 is modified organopolysiloxane obtained by reacting hydrogen-containing organopolysiloxane, unsaturated polyether and alpha-olefin; the component A2 is modified organopolysiloxane obtained by reacting hydrogen-containing organopolysiloxane, unsaturated polyether and bivinyl-terminated organopolysiloxane; the component B is an organic silicon composition composed of a polymer, silicon dioxide and organic silicon resin, wherein the polymer is composed of hydrogen-containing organopolysiloxane, acrylic ester and alpha-olefin; the component C is a thickening agent; and the component D is water. Due to the excellent compatibility between modified organopolysiloxane A1 and A2, the defoaming agent has excellent defoaming performance, stability and clarity in the liquid detergent.

Description

technical field

[0001] The discovery provides a defoamer for liquid detergents, which has a strong foam control effect and can ensure the clarity of detergents, and belongs to the technical field of fine chemicals. Background technique

[0002] Liquid detergents are people's daily necessities. They have the advantages of simple equipment and technology, convenient use, rapid dissolution, and milder to fabrics and skin. They have become the mainstream of washing products. Due to the high content of surfactants, there are many foams, and it is difficult to rinse clean, which not only wastes water resources, increases the cost of laundry, but also causes large-scale water pollution, which is not conducive to energy saving, emission reduction and environmental protection.

[0003] Due to the low surface tension of the defoamer, it can quickly penetrate into the foam system and cause the foam to burst. Adding defoaming agents to liquid detergents can effectively solve the proble...
