Abstract: A mixer includes a shaft and an agitator coupled to the shaft. The shaft and the agitator are configured to rotate together to mix a liquid composition. The mixer also includes a sleeve positioned around the shaft. The sleeve forms a gap between the shaft and the sleeve. The sleeve is positioned in the liquid composition such that the liquid composition fills the gap up to the surface of the liquid composition in the gap to form a liquid seal between the shaft and the sleeve that minimizes an amount of air that penetrates into the liquid composition outside the gap during rotation of the shaft and the agitator.
