Gel Thickeners for Electrolyte-Rich Formulas

Regarding your question about using HEC in gel formulas with high electrolyte content, based on the product information:

• Hydroxyethyl Cellulose (HEC): Yes, HEC is suitable for use in formulas containing electrolytes. It creates a non-ionic gel texture that is not affected by electrolytes. It can also be used in formulas with a pH range of 3 to 9.

In addition to HEC, there are other thickeners that are highly tolerant to electrolytes and can be used in gel formulations:

• Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer: This thickener works without needing heat, can be used in a wide pH range (3-12), and can handle oil up to 20%.
• Carbomer Ultrez 30: This is an electrolyte-resistant gel maker that provides high clarity and does not require heat. It can be used in formulas with a pH range of 4-12.
• Sepimax Zen: This thickener is known for its high tolerance to salt and pH variations.
• Carbomer 2020, Carbomer 1342, Carbomer U20: These types of Carbomers are specifically developed for good electrolyte resistance. They require neutralization with an alkali (like Triethanolamine) to form a gel, typically at a pH of 6-7.

Choosing the best thickener depends on the specific requirements of your formula, such as desired texture, clarity, pH, and other ingredients present.
