Humectant Comparison in Lotion, Sodium Lactate 6


Today is the second to last day of our humectant comparison tests. To review the testing process, I am using the Granny’s Lotion recipe as my testing recipe. Saturday, I will test all of the lotions to discover my favorite humectant!

Today we are making the test batch with Sodium Lactate. As a humectant, Sodium Lactate is derived from lactic acid and will help the skin feel soft and
moisturized for a long period of time.

I decided to test the humectant directly on my skin to add more notes about the feeling on my skin. Sodium Lactate is fluid and clear in appearance, sugar water-like in viscosity. Rubbing the Sodium Lactate into my skin, I felt a velvety and powder-like feel on the skin. I continued rubbing and the feeling changed to a barely-there tacky texture that was also partly silky.

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!
