Subject: URGENT Product development help request


Sumptuous Skin Care Ltd scientists need to make sure that our new bubble bath mixture is the right thickness.

We have a serious problem because the main bubble-making ingredient is too runny at the moment. We think we need to add other ingredients to make it thicker, but do not know which one to use.

Could you please find out which thickener to add? We have a choice of three, and are sending samples to you.

When you've finished, come and compare your findings with ours
