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.

Abstract

One of the purposes of the present invention is to provide an emulsion composition of animo-modified siloxane, the composition having a small initial diameter and good stability with time and dilutionstability. Further, another purpose of the present invention is to provide an emulsion composition which has high adsorption ability to fibers and provides a hydrophilic surface of the fibers. Thus,the present invention is an emulsion composition comprising water and an aminoalkyl group and polyoxyalkylene group-containing siloxane represented by the following general formula (1): (R13SiO1 / 2)k(R12SiO2 / 2)p(R11SiO3 / 2)q(SiO4 / 2)r (1) wherein R1 is, independently of each other, a hydroxyl group, an alkoxyl group, a substituted or unsubstituted monovalent hydrocarbon group having 1 to 20 carbon atoms, or a group represented by the following formula (2), (3) or (6): -(CR2H)a-(NHCH2CH2)b-NH2 (2), -(CR2H)c-O-(C2H4O)d-(C3H6O)e-R3 (3), -(CR2H)f-(R52SiO)s-SiR53 (6); provided that at least one of R1is the group represented by the formula (2) and at least one of R1 is a group represented by the formula (3).

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...
