SK Chemicals Strengthens Position in Cosmetics Packaging with Circular Materials at China Beauty Expo SK chemicals is strengthening its foothold in the cosmetics container market with circular recycling materials optimized for packaging. On May 14, SK chemicals (CEO Ahn Jae-hyun) announced its participation in China Beauty Expo 2025, held from May 12 to 14 at the Shanghai New International Expo Center (SNIEC). Now in its 29th year, China Beauty Expo is the largest beauty trade show in Asia, drawing more than 400,000 visitors from over 80 countries. The event brings together global cosmetics brands and supply chain players--from R&D and manufacturing to packaging and logistics--to showcase cutting-edge trends, technologies, and products. This year's expo featured over 3,200 exhibitors and more than 10,000 brands. Holding the leading market share in China's copolyester sector, SK chemicals presented under the slogan "On-Hand Solution for a Sustainable Future," focusing on commercially available circular materials for cosmetics packaging. SK chemicals exhibited a range of premium skincare product containers developed and commercialized in collaboration with global cosmetic brands. The lineup, which received positive feedback from visitors, included products made from recycled materials and materials designed to enhance recyclability after use. Among the items on display were skin and lotion bottles, cream jars, compact cases, and various cosmetic caps manufactured with ECOTRIA CLARO, a copolyester that can be sorted and recycled within the PET (polyethylene terephthalate) stream. Also showcased were skin and lotion bottles and lotion bottles, fragrance caps, and cushion compact lids made with ECOTRIA CLarO-CR70, a "recycled and recyclable" material that incorporates post-consumer recycled (PCR) content designed to remain recyclable after use. These materials are not only compatible with a variety of container formats but also deliver the mechanical strength and aesthetic quality required for premium cosmetic packaging, which can be attributed to their high-performance copolyester base. Compared to conventional plastics such as PET, copolyester offers superior transparency, even in thick-walled containers, making it ideal for high-end applications where crystal-clear presentation is essential. CLARO-CR70, the aforementioned high-performance circular copolyester material introduced last year, contains up to 70% PCR content. CLARO CR70 uses recycled plastic as a raw material and can be recycled after use, making it an ideal material for establishing a closed-loop plastic recycling system. In addition, the company featured other sustainable materials tailored for beauty applications, including SKYPET CR, a circular PET suited for large-volume body care packaging, and ECOTRION, a 100% bio-based polyol derived from plants, used in cushion puffs and synthetic leather accessories.

SK Chemicals Co.,Ltd, Annual General Meeting, Mar 26, 2025 SK Chemicals Co.,Ltd, Annual General Meeting, Mar 26, 2025, at 13:00 Tokyo Standard Time. Location: g.rium hall, 310, pangyo-ro, bundang-gu, gyeonggi-do, seongnam South Korea Announcement • Oct 16
SK Chemicals Launches ECOTRIA CLARO 300 with Improved Recyclability SK chemicals announced on the 16th the launch of 'ECOTRIA CLARO 300', a copolyester that expands recyclability and molding/processing versatility. The newly introduced material ECOTRIA CLARO 300 possesses the inherent properties of copolyester such as transparency and chemical resistance, while also being recyclable and suitable for Extrusion Blow Molding (EBM). The company explains that this material has a higher viscosity than existing copolyester products even under high-temperature molding conditions, making it suitable for EBM molding. The EBM method is suitable for molding large-sized containers. It creates desired container shapes by heating extruded plastic tubes and inflating them with air, similar to blowing a bubble with bubble gum. Therefore, it requires a high-viscosity material that maintains its shape without melting during the high-temperature molding process in manufacturing. Typical transparent materials like PET and copolyester lack the heat resistance and viscosity required for high-temperature EBM molding conditions, so opaque materials such as PP (polypropylene) and PE (polyethylene) have been mainly used for large-capacity container materials. The company anticipates that ECOTRIA CLARO 300, which can be processed with EBM molding and easily recycled as it's classified as PET, will quickly replace the large-capacity container market where transparency is required. SK chemicals' strategy is to actively target the large-capacity container market requiring transparency, such as large water bottles, juice, and beverages, aiming to expand copolyester sales in the EBM application market to about 30,000 tons.

SK chemicals Unveils Blueprint for Circular Recycle™ and Solutions SK chemicals unveiled a new concept of a complete resource circulation system encompassing its entire business, from materials and production infrastructure based on Circular Recycle™ technology, which chemically decomposes discarded plastics into molecules and converts them back into raw materials, to solutions for recycling waste resources. The complete resource circulation system involves classifying, collecting, and reprocessing discarded post-consumer plastics, turning them back into plastic raw materials, which are converted into materials and products. Once these materialized products are discarded, they can be continuously recycled without generating waste by repeating the same process. The complete resource circulation system pursued by SK chemicals is based on the company's core competencies in Circular Recycle™1) technology and infrastructure. SK chemicals has previously secured the world's first commercial production capability for chemically recycled copolyester products. In March of last year, SK chemicals invested approximately 130 billion won to acquire the chemical recycling business division of "Shuye," a Chinese company specializing in green materials, and established the "SK Shantou" corporation. SK Shantou is a company that produces 70,000 tons of recycled raw material r-BHET and 50,000 tons of chemically recycled PET annually. SK chemicals is not stopping there but is pushing forward with new businesses to provide comprehensive solutions necessary for the process of turning discarded waste resources into products. Establishing a comprehensive recycling system requires the securing of waste plastics for use as raw materials and the development of an efficient waste resource management system. To this end, SK chemicals has signed an MOU with "Shanghai Yuekun Environmental Protection Technology," a Chinese company specializing in waste resources, for the joint development of a waste plastic recycling business. SK chemicals is expected to build a specialized complete resource circulation structure that takes into account the unique characteristics of each industry, going beyond the existing general collection systems for PET bottles and other items. SK chemicals, which holds the No. 1 position in the Chinese copolyester market, showcased a wide range of sustainable copolyester and polyester (PET) products that are already commercialized and used by various global owners worldwide. SK chemicals also presented a range of recycled materials, including the Circular Recycle™ copolyester "ECOTRIA CR" produced using chemical recycling technology, the copolyester "Claro" that can be classified and recycled after use, and the Circular Recycle™ PET "SKYPET CR." SK chemicals exhibited not only materials but also products that have already been commercialized using these materials. Cosmetics, home appliances, and household goods from various global brands that use ECOTRIA CR, Final products such as tire cords and Samdasu Reborn that use SKYPET CR, which have been successfully commercialized using actual Circular Recycle™ materials, attracted great interest among exhibition visitors. In the exhibition hall's designated Circular Recycle™ experience zone, materials made from petroleum and physically recycled materials were displayed alongside those applied with Circular Recycle™ technology, allowing industry officials to directly compare the color and texture of the materials, increasing visitor participation. A wall within the exhibition hall presented an interactive display illustrating the entire Value Chain process for visitors. The process began with the collection of plastic waste in the city, followed by categorization according to plastic type, and then proceeded through depolymerization, culminating in the transformation into a product. Through these complete circulation systems and materials that apply Circular Recycle™ technology, SK chemicals plans to establish itself as a company that provides total solutions covering the entire process to customers seeking to achieve zero waste.

SK Chemicals, Dongsung Chemical, and Black Yak Collaborate on Commercializing Sustainable Footwear SK chemicals (CEO Ahn Jae-hyun), Dongsung Chemical (Co-CEOs Baek Jin-woo and Lee Man-woo), and BYN Black Yak announced on the 18th that they've developed sustainable footwear materials using the naturally-derived material "ECOTRION" and applied them to Black Yak's "Trekking Shoes 343 MAX." Consumers are attracted to the trekking shoes, launched as a new product this spring, because they satisfy both the high functionality required for outdoor activities and the value consumption trend for eco-friendly materials that reduce greenhouse gases. The three companies introduced this product after a year of collaboration. SK chemicals is the supplier of 100% bio-based polyol "ECOTRION," while Dongsung Chemical develops the bio-polyurethane resin "NEOPAN®?" for footwear using this as a raw material. Utilizing this material, Black Yak produced the "Foot Pillow Cushioning Foam," which is applied to the heel support layer of the midsole to minimize loading on the ankle and knee joints. The midsole of trekking shoes is a key component that determines the footwear's weight and acts like a car's suspension to provide the level of function. Cushioning is important because the midsole must absorb the impact on the body and ensure safe strides, even on rough terrain. Dongsung Chemical's bio- polyurethane resin 'NEOPAN' for footwear maintains the high elasticity and flexibility of existing polyurethane resins while using bio-based raw materials, providing the shock absorption function of the " Foot Pillow CushioningFam." EOTRION, utilized in NEOPAN, is an eco-friendly material that uses raw materials that reduce greenhouse gas emissions by approximately 40% in comparison to conventional petrochemical raw materials. It is utilized in the production of spandex, artificial leather, and urethane elastic materials that are challenging to recycle. EOTRION has one less carbon atom in its chemical structure compared to petrochemical materials, which gives it a helical-shaped polymer structure that enables the production of products with high elastic resilience, similar to a spring.
