Modified silicone polyether emulsion, referred to as MPS, as a foaming stabilizer component used in foam products, followed by the market, can be used in a variety of anionic surfactant composition of the foam formula, in the field of new building materials, oil exploitation, foam fire extinguishing agent has been widely recognized. Since 2008, some domestic enterprises have produced this product successively, and the quality and performance of the product have reached the international level of the same product. After 2008, this product basically does not need to import. Due to the unknown safety parameters, further experiments are needed to determine whether they can be used in food.
Mechanism of action:
The action mechanism of silicone polyether emulsion: By changing the molecular internal order, make the surface active agent closely packed neatly between bubble and bubble, forming a layer of dense membrane, makes the compressive capacity particularly strong, able to control the bubble liquid membrane structure stability, the surfactant molecules in the liquid film orderly distribution of the bubble, gives bubble good elasticity and self-healing ability, so as to achieve ideal of bubble effect.
Application background:
Stabilizing foaming of straight chain anionic surfactants, such as K12, AOS, AES and some non-ionic surfactants, have shown excellent stabilizing effect, good performance and lasting stabilizing foaming. Anionic surfactant is the most commonly used foaming material at home and abroad, and although the amount of anionic surfactant foaming is large and rapid, but the foam instability is the fatal blow of many foaming agents. Therefore, many foaming agent manufacturers have experimentally explored again and again, the earliest use of coco acid diethyl alcohol amide (6501), but the domestic production of 6501 is generally synthesized by one-step method, the unreacted oil content is too high, with serious defoaming. Cellulose polyacrylamide, oxidized amine, protein foaming stabilizers generally have certain foaming stabilizing effect, but the foaming stabilizing effect is not ideal. The birth of silicone polyether products has promoted the new development of foam industry, solved many problems of foam instability, and has been gradually understood and recognized at home and abroad.
