Minimizing harmful ingredients...Vegan-certified products too

"Beyond kitchen and laundry detergents, there are countless other cleaning products. There are degreasers, bathroom cleaners, as well as detergents for commercial and industrial use, but until now it has been difficult to find information on how to use them correctly. Through the Sejemol YouTube channel, I want to teach proper usage methods and lead an eco-friendly detergent culture."

"Sejemol" is a D2C (Direct to Consumer) brand that specializes in a wide range of detergents, including those for household, commercial, industrial, and pet use. Born in 1994, CEO Yeon Eungjun is a young entrepreneur and expert who has devoted more than eight years to detergent R&D and distribution, following in the footsteps of his father, who has run a detergent manufacturing company for 23 years. Five years ago, he founded Sejemol and has been directly operating it in order to focus on distribution and branding.

The biggest differentiator of the Sejemol brand is product quality. CEO Yeon said, "Our degreaser 'Cocoz 5-Minute Cleaner' boasts the No. 1 cleaning power in Korea," adding, "It received test results from a domestic institution showing more than 90% cleaning power compared with other products in the same industry. It can remove stubborn grease on burners and hoods in fried-chicken restaurants or barbecue restaurants 20 to 30 minutes faster than the usual commercial standard."

In particular, minimizing harmful ingredients is another key distinction. Harmful and toxic substances are either not used at all or used only in the minimum amounts when absolutely necessary. The company applies its own internal standards that are far stricter than legal requirements when manufacturing products. In fact, the dishwasher detergent "Pposonghouse All-in-One Powder" has obtained vegan certification and is attracting attention from consumers who value the environment and ethics. Sejemol has also introduced the "Pposonghouse" pet deodorizer, designed with ingredient safety and usage environment in mind so that it can be used safely in spaces shared by pets and their owners.

CEO Yeon said, "We have focused our R&D on gentle plant-based and naturally based detergents," and added, "I founded Sejemol to break away from the traditional wholesale-centered distribution structure, build our own brand, and increase touchpoints by communicating closely with consumers."

Sejemol also runs a YouTube channel called "Detergent Lab Sejemol." The channel was launched after CEO Yeon attended the "1 Million Creator Commerce Success Strategy" public seminar hosted in December 2021 by the global e-commerce platform "Cafe24." Realizing that operating a YouTube channel is essential to effectively scaling up a business on a D2C shopping mall, he began filming and editing videos himself to share a wide range of knowledge about detergents and cleaning.

Based on CEO Yeon's expertise, the channel delivers professional knowledge on various detergents for household, commercial, industrial, and pet use, and has successfully attracted more than about 13,800 subscribers. During the COVID-19 pandemic, when interest in disinfection using natural detergents surged, the channel posted content on "how to use sodium percarbonate," which recorded more than 270,000 views. In addition, by releasing numerous practical "tips" that can be applied immediately in daily life, such as how to unclog drains and how to mix baking soda and citric acid, the channel has surpassed a cumulative 7.67 million content views. Recently, as it has started introducing how to use commercial and industrial detergents, many self-employed viewers have joined the audience.

Sejemol is leveraging Cafe24's "YouTube Shopping" function to naturally showcase its products via the "Store" tab within the channel and through each piece of content, thereby boosting purchase conversion rates and business efficiency. Since introducing the YouTube channel, sales on its D2C shopping mall have grown by a total of 5 to 6 times, and are increasing by 50% every year. The membership sign-up conversion rate and repurchase rate have also nearly tripled.

Sejemol is also proactive in entering overseas markets and has already been exporting for four consecutive years. It generated sales of approximately 70,000 dollars in 2024 and 100,000 dollars in 2025, expanding its market from the United States and Vietnam into Central Asia. In recognition of its contribution to exports, the company received a commendation from the Governor of Gyeongsangbuk-do and a ministerial award from the Ministry of SMEs and Startups.

CEO Yeon said, "When we participate in overseas exhibitions or trade missions and showcase our products, there is tremendous interest in 'K-Detergents.' The technological prowess of Korean detergents and the level of safety regulations are world-class, but brand power is still weak. Through the Sejemol brand, I want to actively pioneer new markets and widely promote the excellence of Korean detergents." He added, "Recently, we have been receiving a great response by sharing correct detergent knowledge in 30-second short-form videos, and going forward, we hope to establish ourselves as both a YouTube channel and a company that leads knowledge about household chemicals and an eco-friendly detergent culture."
