Usage rate 0.5–5%
Texture Smooth, slick liquid
Scent Nothing much
Charge Non-ionic

Why do we use it in formulations? PEG-6 Caprylic/Capric Triglycerides are pretty versatile! I primarily use this ingredient as the active cleansing ingredient in micellar water formulations; I’ve experimented with every liquid surfactant/solubilizer I own and only PEG-6 Caprylic/Capric Triglycerides  produce good results.

PEG-6 Caprylic/Capric Triglycerides can also be included in body washes and other surfactant products to make them gentler and more emollient, and as a solubilizer.

Do you need it? If you want to make micellar water I consider it to be essential. Otherwise, no.
Refined or unrefined? PEG-6 Caprylic/Capric Triglycerides only exists as a refined product.
Strengths Excellent skin feel, even in leave-on applications. Versatile, gentle ingredient.
Weaknesses Not considered natural, can be harder to find than other surfactants.
Alternatives & Substitutions In micellar water I have not found any suitable alternatives to PEG-6 Caprylic/Capric Triglycerides. In other projects other water soluble “oils” like Olivem 300 will work well.

DO NOT use Caprylyl/Capryl Glucoside or Caprylic/Capric Triglycerides instead of PEG-6 Caprylic/Capric Triglycerides. Make sure you look at the INCI of what you are purchasing and ensure it matches. PEG-6 Caprylic/Capric Triglycerides are sometimes sold as PEG-6 Caprylic/Capric glycerides, but will always have the “PEG-6” part and will never include the word “glucoside”.

How to Work with It Include it in the water phase of your products; PEG-6 Caprylic/Capric Triglycerides can be hot or cold processed.
Storage & Shelf Life Stored somewhere cool, dark, and dry, PEG-6 Caprylic/Capric Triglycerides should last at least 2–3 years.
Tips, Tricks, and Quirks PEG-6 Caprylic/Capric Triglycerides are in no way interchangeable with Caprylic/Capric Triglycerides or Caprylyl/Capryl Glucoside.
Recommended starter amount If you’re primarily using PEG-6 Caprylic/Capric Triglycerides for micellar water 30mL (1fl oz) will go a very long way. If you also wish to use it as a water soluble emollient I’d purchase at least 100mL (3.3fl oz).
Where to Buy it  Buy it from an online DIY ingredient supplier.

Check the INCI to be certain you are not purchasing Caprylyl/Capryl Glucoside or Caprylic/Capric Triglycerides by accident!
