摘要：

MQ硅树脂是四烷氧基硅烷（Q单元）和三甲基乙氧基硅烷（M单元）的共聚产物，出色的防水与持妆能力，致使其在化妆品领域作为成膜材料运用广泛，因此评估和筛选适宜的MQ类成膜剂对提升配方开发效率十分重要。通过凝胶渗透色谱、接触角测量仪、透气性分析仪等探究了21款市售MQ硅树脂的成膜性、成膜时间、疏水疏汗疏油性、透气性与分子量及分布状态等性能间的内在联系。结果表明，MQ硅树脂的性质与其分子量的大小和分布状态有一定关系，对于分子量较高、分布较窄的MQ硅树脂类成膜剂，其成膜脆性高、疏水疏汗性强、透气率低、成膜时间快。而在分子量减小，聚合物分散性指数几乎不变或者拓宽，即分布较宽的情况下，MQ硅树脂表现出较柔软、疏油性较好、疏水疏汗性一般、成膜时间较长、透气率较高的特征。

Abstract:

MQ silicone resin is the copolymerization product of tetraalkoxysilane （Q unit） and trimethylethoxysilane （M unit）. It has a special double-layer tightly cross-linked spherical network structure, which not only has excellent water resistance, thermal stability and compatibility, but also is long-lasting, safe and non-irritating. So it has become one of the indispensable film-forming ingredients in cosmetic formulations. Therefore, it is vital to evaluate and screen the MQ silicone resin for improving the efficiency of formulation development. The molecular structure and film morphology of 21 MQ silicone resins were analyzed by GPC, microscopy and air permeability analyzer. According to the results, the relationship between the molecular structure of MQ and its application properties, such as film forming time, film brittleness, air permeability, water resistance, sweat resistance and oil resistance, were explored. The results show that the properties or performance of MQ silicone resin are depended on the size and distribution of its molecular weight. For the MQ-type silicone resin filmogen with higher molecular weight and narrower distribution, its film properties of hardness, water resistance and sweat resistance are enhanced with the increase of molecular weight, but its air permeability is subsequently weakened and film forming time is shorter. When the molecular weight decreases and the polymer dispersity index is almost unchanged or broadened, the MQ silicone resin show softer film, better oil resistance, longer film-forming time and higher air permeability.

Key words: MQ silicone resin, film-former, molecular weight
