"Senka Cosmoat C, A Series" is a water-soluble polymer-type thickener (liquid product) composed of W/O (water-in-oil) emulsions using isoparaffin-based hydrocarbons in the oil phase. It is useful as a thickener for shampoos, conditioners, body soaps, hand creams, facial cleansers, hair dyes, and cosmetic perms. Being a liquid product, it is easy to handle and does not require special dissolution equipment that is typically needed for cellulose-based, starch-based, or guar-based thickeners. By selecting various products according to ionic properties and purposes, it can demonstrate thickening power across a wide range of pH levels, allowing for the creation of formulations with various viscosities and sensory experiences. 【Features】 - The target dissolution viscosity can be adjusted by the amount added. - Dissolution in water can be achieved with paddle stirring, without the need for special dissolution equipment. - It has lower stringiness (viscosity that pulls like a thread) compared to starch-based thickeners and shows high thixotropy. - It exhibits thickening power across various pH levels. - It can create formulations with various viscosities and sensory experiences. - There are products composed only of ingredients listed in the 2021 standards for quasi-drug raw materials. *For more details, please refer to the PDF document or feel free to contact us.*

Here is an introduction to our "Cosmetics Division." We handle the "Cosmoat Series," which includes "Polyquaternium-6," suitable for solid soaps, facial cleansers, and hair colors, as well as "Polyquaternium-7" and "Polyquaternium-22." By incorporating these agents into personal care products such as shampoos and body soaps, we provide viscosity adjustment, improved texture after use, and functionality. 【Product Lineup】 ■ Polyquaternium-6 ■ Polyquaternium-7 ■ Polyquaternium-22 ■ Polyquaternium-39 *For more details, please refer to the PDF document or feel free to contact us.

This document introduces the conditioning polymer "Senkacosmo V-22 Series," which excels in coacervate formation. It includes information on "coacervate formation ability during shampoo use," as well as "the feel of hair during and after drying," presented through tables and graphs. We invite you to read it.

Senka Cosmoat C-7S2" is an emulsion-type thickener that is liquid and dissolves quickly, allowing for direct addition to water-based products that require thickening. It exhibits high thixotropy without stringiness, enabling it to create viscosity and envelop hair without dripping. When incorporated into hair color treatments, it helps to reduce color fading after dyeing, improves combability, and results in a soft finish. [Features] - The desired dissolution viscosity can be adjusted by the amount added. - It does not clump when added to water, unlike starch or guar-based thickeners. - It has lower stringiness than starch-based thickeners and shows high thixotropy. - It demonstrates thickening effects in acidic to weak alkaline ranges. *For more details, please refer to the PDF document or feel free to contact us.
