Why do we use it in recipes? It provides fantastic gel-like thickening without the snottiness of gums like xanthan and guar. It also boosts surfactant performance noticeably.
Do you need it? It’s easily my favourite plant-derived thickening gum; I’d recommend it over xanthan and guar.
Strengths Creates beautiful, clear, carbomer-like gels and noticeably boosts surfactant performance. Has a much better leave-on skin feel than gums like xanthan and guar.
Weaknesses Harder to find than gums like xanthan and guar.
Alternatives & Substitutions I haven’t come across anything that works quite like HEC does. Xanthan gum will offer similar thickening, but gives a far less pleasant end consistency and does not boost lather the way HEC does.
How to Work with It Whisk the hydroxyethylcellulose into some glycerin to break up any lumps before adding the rest of the water phase. It will thicken over the course of several hours without heating; the thickening process can be sped up by gently heating the mixture in a water bath.
Storage & Shelf Life Stored somewhere cool, dark, and dry, hydroxyethylcellulose should last at least three years.
Tips, Tricks, and Quirks Make sure it has time to fully hydrate before continuing with your formulation to ensure a uniform end product.
