Fragrance Testing at MMS 2

Have you ever wondered how we choose the fragrances that go into our catalog? There are several tests each prospective fragrance goes through to be possibly added to the catalog.

The cold process soap test is the hardest test and one that most fragrances fail for one reason or another. A fragrance could seize a batch, fade quickly after curing, or alter and not smell appealing anymore. We start with a basic soap recipe that we keep the same for the testing purposes. Each batch has 1 pound of fats. We usually make between 8 and 16 batches in a testing session. We start with a basic soap recipe that we keep the same for the testing purposes.

Our test recipe is:

4 oz Coconut Oil or Palm Kernel Oil. We use either one of these oils since they have similar saponification values. We will just use what we have available in the lab at the time.

4 oz Olive Oil

8 oz Hydrogenated Soybean Oil

2.2 oz Sodium Hydroxide

6 fl oz water

We test under extreme risks and follow our noses to the end. Extreme risks include high temperatures, speed of mixing, length of mixing time and more.

As you can see from these photos, some soaps look great, others look bad. Several failed, and some with no obvious reasons. 12 soaps of the 35 here failed and that equals a failure rate of 34%. Some of the failed fragrances we reformulate and retest, but some don’t move us enough to reformulate.

About Andee

Director of Happiness. I'm a thirty-something soap snob. I've grown up with handmade soaps, and I love them! I really like making lotions, soaps, and perfumes. I adore mixing scents to come up with something new. My favorite scent is either Wicked or Cotton Candy. I tend to hoard fragrances, I even have an Earl Grey Tea from the MMS catalog. I won't tell you how old it is, but it sure is good!

    hi – well, the coffee soap has set up fine I think. it has been 24 hours and I just cut it. it was still rather soft but I was afraid to leave it over night and get too firm to cut. still looking forward to tomorrow and the cold press soap week. thanks. Emily
