- After three months at 60°C, there were no changes in particle size or viscosity, resolving issues that could cause "clumping" or "smudging" in products like eyeliners. We will solve the concerns of researchers and developers regarding dispersions as colorants. - While ensuring long-term stability, we reviewed all production processes from scratch to achieve a close color match, discovering the optimal timing and methods to balance both storage stability and deep black characteristics. We designed it to make it as easy as possible for customers who valued the color of previous products to consider alternatives. New customers will also be able to experience both color and stability. - Additionally, we have incorporated our uniquely developed dispersing polymer, which excels in "water resistance," "sebum resistance," and "abrasion resistance," so we have resolved only the issues of thickening and aggregation without compromising performance. - We have passed eye mucosa irritation tests, skin irritation tests, and patch tests, so you can use it with confidence. We would be grateful if you could consider it. We look forward to your request for samples.

The "Color Dispersion Series" is a color base that disperses various pigments in water. It can be considered for use in cosmetics such as eyeliners, mascaras, eyebrow products, and water-based nail polishes. By selecting the appropriate polymer, it is possible to improve dispersibility, stability, and re-dispersibility. Enhancing dispersibility and stability will slow down changes over time, such as thickening. 【Features】 ■ Achieves "high color development" through high dispersion and uniform dispersion ■ Contributes to "high water resistance" through soap-free dispersion design ■ Realizes "long-term storage stability" through optimal dispersion design *For more details, please refer to the PDF materials or feel free to contact us.

The "Sunscreen Dispersion Series" is a dispersion of microparticle titanium dioxide and microparticle zinc oxide for UV care cosmetics. Starting with sunscreen agents (sunscreens), it provides UV cut functionality to cosmetics such as UV primers, medicated emulsions, and BB creams. In the "Silicone Dispersion Series," we offer dispersions of titanium dioxide and zinc oxide using dimethicone and cyclopentasiloxane (D5). Additionally, in the "Non-Silicone Dispersion Series," we have dispersions using hydrocarbon oils and water as solvents, considering environmental impact. 【Features】 ■ Dispersed to an optimal particle size for UV scattering, enhancing "UV cut functionality" ■ Prevents scattering of visible light through microparticle dispersion, achieving "high transparency" ■ Achieves "long-term storage stability" through optimal dispersion design ■ Capable of achieving the highest level of UV cut effect even with "non-chemical formulations" *For more details, please refer to the PDF materials or feel free to contact us.

Using our processing technology, we have finely dispersed "titanium dioxide and zinc" with UV-cutting effects into particle sizes that scatter ultraviolet wavelengths while allowing visible light to pass through easily, achieving a high level of both UV-cutting effectiveness and transparency. It can also be used as a UV-cutting agent in sunscreens and makeup bases. *Skin irritation tests and patch tests have been conducted. <Features> 【High UV Scattering】 We control the particle size of titanium dioxide and zinc to be optimal for UV scattering. A non-chemical formulation can achieve "SPF50+ PA++++". 【High Transparency】 The particles are dispersed to scatter wavelengths of approximately 250-400nm in the ultraviolet range while allowing wavelengths of approximately 400-800nm in the visible light range to pass through easily, making it less likely to appear white when blended. 【Choice of Solvents】 We offer a variety of solvents, including D5, dimethicone, hydrocarbon-based, and water-based solvents, to accommodate diverse orders. You can choose based on various aspects such as feel and volatility. 【Commitment to SDGs】 It is possible to design formulations "without using UV absorbers," addressing concerns about environmental pollution and skin irritation. Please feel free to contact us if you would like more details or samples.

• Photocatalysts and various wall materials (exterior and interior walls, etc.)

Rice cookers, pens, inkjet inks, cosmetics, toys, and more are all around us, overflowing with various colors. Pigments are one of the materials (raw materials) used to color objects. Dispersing refers to the process of evenly distributing pigments (colors) in a solution and stabilizing them so that they do not clump together or separate. I will explain the unfamiliar keyword "dispersion" in an easy-to-understand manner, using real examples. This has been created as an introduction for those handling chemical products (especially coloring agents like inks, paints, and toners) from high school students to working professionals. Why do color inconsistencies occur? Why is there a lack of gloss? This document explains how these issues can be resolved through dispersion technology based on chemical and physical methods.
