Do your products change the colour of a finished product?

Our ingredients are packaged in a variety of types and sizes. For smaller quantities on our anhydrous ingredients, liquids come in 18 kg pails, and solids in 12 and 16 kg pails, 25 kg boxes or 95 kg drums. For larger quantities, drums come in 188 or 190 kg. Our cleansing additives are only available in 200 kg drums; however, 20 kg pails can be made available on a minimum quantity basis.
Do your products need to be temperature controlled?
Generally, no, but we do strongly recommend following the storage guidelines found on the SDS. For our anhydrous products this would be a cool dry place. Our cleansing additives, because they contain water, these should always be stored above 15 ºC, and prevented from freezing.
What do you mean by T.I.F.™ Concept?
