In March 2026, a senior industry formulator released a professional selection guide for emulsifiers, revealing the core reason for the texture gap between high-end and ordinary products with the same oil and water phases caused by different emulsifiers. Emulsifiers are not just simple tools for mixing oil and water, but the backbone of skin care formulations. They can not only reduce the oil-water interfacial tension, but also form biomimetic liquid crystal structures, build gel networks, control the release rate of active ingredients, and directly determine the skin feel and efficacy of products. The guide sorts out the applicable scenarios of five categories of emulsifiers and classic combinations according to the product texture from light to heavy. From the refreshing gel texture of Seppic Sepiplus 400 to the light water-in-oil texture of Croda Cithrol DPHS, each emulsifier has its own focus on skin feel, oil phase upper limit and applicable products. Among them, the liquid crystal emulsification system has far better moisturizing and barrier repair effects than the ordinary emulsification system due to its skin stratum corneum-mimicking structure, becoming the core technology of high-end skin care products. The guide also points out that the matching of emulsifiers and oil phases, process control and cost differences are all key factors affecting the final texture of products.
