KISCO’s flagship range of Synozol Dyes have long been known to be the industry standard for Right-First-Time Dyeing (RFT). This means that every time you use our dyes, you achieve the result that you are expecting. No waste, no re-dyeing. Our RFT expertise has been applied across many of KISCO’s products. Our Synozol K dyes are specifically optimised for RFT. This ensures that the same colors can be achieved every time, delivering benefits with respect to quality, reliability, and sustainability.

Parachloroanilines (pCAs) are a class of chemicals that can be found in some dyes. They are hazardous due to their potential carcinogenicity, environmental persistence and ability to bioaccumulate. They pose significant health risks, including liver, kidney and thyroid damage. In 2018 KISCO launched our Synozol Nature dyes. These dyes are highly pure and completely PCA-free, meeting the requirements of leading brands that are focused on product safety.

KISCO is a partner in this sustainability alliance of the world’s leading chemical companies.

Sustainable Chemistry for the Textile Industry (SCTI) is a not-for-profit organization founded in 2020. Our six founding members – Archroma, CHT Group, Kyung-In Synthetic Corporation (KISCO), Pulcra Chemicals, Rudolf Group and Tanatex Chemicals – are market leaders who are committed to drive collaboration to achieve sustainable and safe practices for workers, communities, environment and consumers.

In 2022, SCTI teamed up with bluesign® to create the Sustainable Chemistry Index (SCI), a first-of-its-kind index that enables stakeholders to assess the sustainability of textile chemical products.

KISCO is accredited under the world’s leading textile industry compliance schemes including bluesign®, ZDHC, GOTS, and The List by INDITEX. We scored very highly in our most recent bluesign® audit. Our facilities are regularly audited by our partners and we comply with or exceed all of Korea’s world-class environmental, labor, and safety regulations. We have products that comply with CSCL, K-REACH, EU REACH, TSCA, China REACH, KKDK, and other regulatory frameworks.

KISCO’s ESG strategy and performance is outlined in our annual report and on our website. We comply with a large number of supplier code of conduct agreements and require similar commitments from our own suppliers. Our policies cover our environmental and safety performance, our social achievements, and our governance compliance measures.

Recent initiatives include investing in more efficient waste disposal technologies and the adoption of waste to energy processes. We are constantly improving the sustainability of our products to help our customers to save water, time, and energy.

KISCO’s targets and performance with respect to a wide range of environmental parameters, including Greenhouse Gas Emissions, are reported to a range of initiatives and in our annual Sustainability Report.

Certification and compliance

KISCO has over 200 different products registered in the bluesign® bluefinder and a total of over 400 products listed on the ZDHC gateway. In addition, we also have around 150 products registered with GOTS and around 30 registered with ECOPASSPORT. Finally, KISCO’s data in “The List by INDITEX” covers around 800 different products.

Each of these certifications demonstrate the safety of our products against published standards that are designed to eliminate harmful substances. In addition, the bluesign® audit certifies that our facilities and product stewardship processes protect our staff and the environment.

KISCO’s commitment to sustainability in our development and supply of fine chemicals for electronics and other application is also strong. We are in the process of aligning our operations with standards set by the Responsible Business Alliance (RBA). Our commitment extends to our food products, which are certified for their purity and compliance with social and religious standards. Lastly, our processes adhere to various International Standards.

KISCO has the following certifications:
World Class 300
ISO 9001 (Quality Management System)
ISO 14001 (Environment Management System)
OHSAS 18001 (Health & Safety Management System)
FSSC 22000 (Food Safety System Certification)

We have certified a number of our key products under the ECOPASSPORT scheme. However, the vast majority of our products are listed on the ZDHC Gateway and/or in the bluesign® bluefinder. These schemes provide similar certification of products to ECOPASSPORT. One of the key aims of KISCO’s membership of SCTI is to help reduce duplicated certifications across our industry. If you need help understanding how certifications overlap and confirm similar attributes, please contact your distributor.
