Scent

Characteristically detergent-y

Active Surfactant Matter

51%

pH

11–12

Charge

Non-ionic

Solubility

Water

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.
