Vegetable Oil Glycereth Ester Foam Boosters

Tuesday, April 30, 2024
5:00 PM – 6:00 PM EDT
Abstract:

This study examines vegetables oil glycereth esters (VOEs) for synergies in foam boosting and foam stabilization when used with alcohol ethoxy sulfates (AES). VOEs can be used to lower the amount of AES in formation while maintaining performance and lowering 1,4-dioxane levels. They offer advantages over similar surfactants, such as cocoamidopropyl betaine (CAPB), by having more sustainable feed stocks and potentially less irritating impurities. The VOEs used in this studied were synthesized by transesterification of vegetable oils with ethoxylated glycerin and formulated at a ratio of 1:3 with AES. Foam volume and stability were evaluated by Waring blender and Sita Foam Tester while foam density was determined Hart deGeorge and Sita Foam Tester.  Formulations using VOES with an average of 10 moles of ethylene Oxide (EO) or greater produce higher levels of foam and denser lathers than those that did not contain foam boosters or CAPB.  Vegetable Oil glycereth esters can serve to replace CAPB as a foam booster and stabilizer e.g., in personal care and hand dish soap, while potentially reducing the amount of AES in a formulation.
