Description

DETAILED DESCRIPTION OF THE INVENTION      Low foaming liquid detergent composition containing silicone foam inhibitor and fatty acid ester                                 Technical field   The present invention relates to detergent compositions having controlled foaming properties. More specifically, The present invention relates to a foam control system, which comprises a silicone foam control agent and a specific fatty acid ester. ).                                 Background art   Effective and uniform control of the amount of foam formed during the washing operation is a requirement for additional improvements. Year in terms of well-known product formulas. Excessive foaming, especially drum cleaning When carried out in a washing machine, the whole cloth chest often awarded by modern detergent compositions And may affect the benefits on fabrics and fabrics. Too much in the washing machine Foaming not only interferes with and reduces the action of the washing liquid on the fabric, but also This may be caused by residual foam in the rinse cycle. Not only increase the amount of foam in (the inherent difficulty of foam suppression), but also the active agent to the rinsing process Agents, such as fabric softeners], which is undesirable.   This problem often arises when formulating foam control systems into conventional surfactant detergent mixture compositions. In the prior art. As the foam control system, for example, silicone Foam suppressants are mentioned. However, foam control systems such as silicones are not May be difficult to maintain as a dispersion in the material and difficult to process. It is difficult. In addition, silicone suds suppressors are expensive.   In this context, European Patent Application No. 949220, filed June 28, 1993 No. 23.0 describes conventional anionic dyes in combination with α-branched anionic surfactants.
