KIN Saline Solution

KIN Saline Solution (Suero Fisiológico) is a preservative-free sterile solution produced by Laboratorios KIN. Founded in 1964 in Barcelona, Spain, the company has grown from a local dental care firm into an international leader in oral health and hygiene.

The product is primarily manufactured in Spain, where Laboratorios KIN operates its main production facilities and research centers. The brand remains privately held by the founding family (Balasch family) through Laboratorios KIN S.A., maintaining its headquarters in Barcelona. While the company has expanded its commercial reach to over 60 countries and established several international subsidiaries across Brazil and Central America, its core manufacturing and research operations continue to be centered in Spain.
