Innovation: SEPPIC’s driving force
In the 1990s, two major innovations accelerated SEPPIC's international development. SEPIGEL 305, the first ready-to-use liquid polymeric thickener, effective across a wide pH range, quickly became a leading product in cosmetic formulation. At the same time, SEPPIC created MONTANOV, the first product line of green emulsifiers.
