Sodium Laureth Sulphate 26.5% and Electrolytes
Hi,we currently use Sodium Laureth Sulphate 26.5% in our hand wash products and thicken with salt to around 4000 - 5000cP. Recently we have had some problems with high viscosities (about 2,000cP over spec). Looking at the product specification for SLES, there is < 0.5% Sodium Sulphate by mass in there.If we receive a delivery of SLES that contains 0.1% Sodium Sulphate, then receive a delivery that contains 0.5% Sodium Sulphate that equates to a variable between 1Kg to 5Kg Sodium Sulphate between deliveries once scaled up into a batch of product.So could this variable be causing the viscosity problems with Sodium Sulphate being an electrolyte? Has anyone ever had this problem before?Thanks.
