N O T E S

The substance is usually sold as a 50% concentrate. The linear alkyl chain has typically 10 to 13 carbon atoms, approximately in the following mole ratio (percentage of alkyl chain lenght relative to the total component) C10:C11:C12:C13=13:30:33:24. The formulations of linear alkylbenzene sulfonates available in US contain also 0-5% C14 component
