## Questions & Answers

**Q: Does this stain/mark the bath?**
A: We have had no problems with marks or stains

**Q: What age is this from as I have a 14 month old son**
A: Can’t remember to be honest and I have thrown the bottle away now !

**Q: "sles and paraben free" but the main ingredient is sodium laureth sulphate, please explain**
A: SLES is short for Sodium laureth sulfate which is similar to Sodium lauryl sulfate (SLS) but which has been through an additional process called ethoxylation. This process involves treating the detergent with ethylene oxide which makes the molecule more readily water-soluble and potentially less irritating to the skin. 
SLS is sodium lauryl sulfate, a foaming agent - what makes it bubbly and frothy.
If you need to query this more then you will need to contact the manufacturer.
Hope this helps

**Q: Is the liquid red and as you pour the bath water turns blue? Or does the bath water turn red then gradually turn blue?**
A: The liquid is red and turns blue as it hits the water and is swished around. So the bath water just turns blue.
