Why do we use it in formulations? Decyl glucoside can be a good primary or secondary surfactant, contributing foaming/cleansing to an end product. It has a really rich, dense lather that is lovely in our formulations.
Do you need it? No
Refined or unrefined? Decyl Glucoside only exists as a refined product.
Strengths Decyl Glucoside is a relatively easy to source “natural” surfactant with lovely lather.
Weaknesses It has a fairly high pH and isn’t a great solubilizer; I tend to choose Caprylyl/Capryl Glucoside over the other glucosides.
Alternatives & Substitutions I tend to prefer Caprylyl/Capryl Glucoside in any recipe that calls for decyl glucoside, though the lather of Decyl Glucoside is richer + thicker, so I might blend Caprylyl/Capryl Glucoside and Decyl Glucoside to get some of the solubilizing powers of Caprylyl/Capryl Glucoside and the lather of Decyl Glucoside.
How to Work with It Include it in the water phase of your formulations; it can be hot or cold processed.
Storage & Shelf Life Stored somewhere cool, dark, and dry, Decyl Glucoside should last at least two years.
