Among the diverse range of fatty alcohol raw materials, cetearyl alcohol (C16 alcohol + C18 alcohol) has emerged as a "favorite" in the beauty industry due to its excellent performance. Its unique compounding advantages and stable characteristics continue to lead the innovation trend of skincare product formulations. The rise of cetearyl alcohol is no coincidence. From a scientific perspective, it perfectly complies with the "C6 Principle"—with a carbon chain length difference of only 2 carbon atoms, it can form a stable α-gel structure and avoid phase separation. In terms of raw materials, it is mainly derived from common natural fat sources such as palm oil and beef tallow, offering much higher cost-effectiveness than scarce long-chain fatty alcohols. Meanwhile, the C16-C18 carbon chain length perfectly matches mainstream non-ionic emulsifiers, significantly improving the thermal stability of products. In formulation practice, the ratio of cetearyl alcohol is particularly crucial. The industry mainly adopts C16:C18 ratios of 30:70 or 50:50—the former enhances product hardness and heat resistance, while the latter offers moderate consistency and wide applicability. Stable emulsions can be achieved when stearyl alcohol content is within the range of 10%-70%. Additionally, when the molar ratio of emulsifier to fatty alcohol is controlled between 1:3 and 1:4, the most stable lamellar liquid crystal structure is formed, balancing product texture and stability. As a "backbone" ingredient in skincare formulations, cetearyl alcohol effectively addresses industry pain points such as cream delamination and coarsening through scientific compounding, providing ideal texture support for products like face creams and lotions. Its balance between safety and efficacy has made it a core raw material in the R&D of beauty enterprises. For more information, you can click: https://www.tiktok.com/@mia_iot
