<p>A customer once asked a question that may sound quite technical:<br /> <br /> “If a cosmetic formula contains both water and oil, could an inconsistent water-oil ratio during dispensing mean that the pump is defective?”<br /> <br /> The answer is not simply yes or no.<br /> <br /> A pump dispenser does not normally cause a properly formulated product to separate into water and oil. However, the pump structure and dispensing conditions can affect the composition of each dose when the formula is already separated or does not remain uniform.<br /> <br /> To understand why, we need to look at the formula, the pump mechanism, and how the two work together.</p>
