Wanhua Chemical Unveils Groundbreaking Bio-Based 1,3-Butylene Glycol to Transform Skincare Industry

On February 19, Wanhua Chemical made waves at the PCHi exhibition with the launch of its innovative bio-based 1,3-butylene glycol designed for use in moisturizers and solvents across various cosmetic applications, including serums, cleansers, and sunscreens.

Why is bio-based 1,3-butylene glycol attracting so much attention? As early as June 2022, Wanhua announced plans for a 30,000-ton annual capacity skin conditioning agent project, which includes building a 7,000-ton/year industrial-grade and a 23,000-ton/year cosmetic-grade 1,3-butylene glycol facility. This new product marks a significant milestone as the world's first bio-based version, aligning perfectly with the beauty industry's growing demand for low-carbon, sustainable, and innovative raw materials.

Currently, 1,3-butylene glycol is widely used in cosmetics for its moisturizing properties and effective antibacterial action. It is less irritating and allergenic compared to glycerin and propylene glycol. Beyond cosmetics, it is also essential in synthesizing various resins, coatings, adhesives, and key intermediates for pharmaceuticals.

Global production of 1,3-butylene glycol exceeds 60,000 tons annually, with major players concentrated in the U.S. and Japan. Oman OQ stands as the largest producer with an annual capacity of 30,000 tons. Other notable companies include Kao Corporation, Daicel Chemical, Hecar Energy, Wanhua Chemical, and Jiangsu Huachang Chemical.

As the beauty market continues to expand rapidly, demand for 1,3-butylene glycol is projected to grow at over 5%, with consumption in China expected to exceed 10%. As the largest potential consumer market, China's promising future is a key reason for Wanhua's focus on developing this product.

How is the bio-based 1,3-butylene glycol technology achieved? The synthesis methods include acetaldehyde condensation, propylene glycol methods, and biosynthesis. Among these, biosynthesis using microbial fermentation of sugars is the most environmentally friendly process, although current yields and efficiencies are limited by microbial strain and enzyme technologies.

Wanhua's bio-based 1,3-butylene glycol, branded as Carfil® 1,3BG, is developed using non-staple raw materials, avoiding competition with food resources. The production process employs green electricity and low-carbon techniques, ensuring 100% natural sourcing and a complete carbon cycle. This significantly reduces carbon emissions compared to traditional petrochemical routes, providing a new pathway for sustainable industry development.

Additionally, Wanhua Chemical is exploring innovative and sustainable solutions, such as rhamnolipids, carbomers, diols, and silicone emulsifiers, to further enhance its product offerings.
