In today’s program we cover product testing and how you can become an expert evaluator of the personal care products you create.

In this episode you’ll learn:

• Why you should test your own products
• How personal evaluations can direct your revisions
• What product use can teach you about raw materials
• 8 step process for evaluating cosmetic prototypes

Today’s challenge

Run a blinded test on two different products. For example, go get a sample of a low-cost shampoo or body wash and another sample of a similar smelling higher priced product. Or you can use your own formulas and compare them to a market leader. First use the product and write down scores for the characteristics we talked about earlier in this show. If you are testing a hair product make notes about the different aspects of the foam and how well your hair feels and combs after your done. Give your prototype and the benchmark scores for each characteristic. Then see if you can tell any differences. See if you can reduce the cost of one of your formulas by 10%.

When you’ve completed the challenge come over to the show notes and leave a comment about your experience.
