Problems solved by technology

[0003] However, amino-modified siloxanes have the following problems: high hydrophobicity and difficulty in emulsification, large particle size during emulsification, and decreased emulsion stability
[0007] However, although the conventional amino-modified silicone emulsion composition has a high adsorption force to fibers, if the fiber is treated with this emulsion composition, there is a problem that the surface of the fiber becomes water-repellent.

Description

technical field [0001] The present invention relates to emulsion compositions comprising aminoalkyl and polyoxyalkylene containing silicones. Background technique [0002] Amino-modified silicones are used in various fields such as fiber treatment agents, mold release agents, polishing agents, cosmetics, especially hair cosmetics. As a form when amino-modified siloxane is used, it has conventionally been used after being diluted with a solvent. However, in recent years, concerns about adverse effects on the environment and health have grown, and it has been increasingly used as an emulsion. [0003] However, amino-modified siloxanes have problems in that emulsification is difficult due to their high hydrophobicity, the particle diameter during emulsification is large, and emulsion stability decreases. Therefore, an emulsion composition of an amino-modified silicone having a small particle size and improved stability is desired. [0004] In addition, an emulsion compositio...
