| 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. |
