Its primary function stems from its amphiphilic nature, possessing both hydrophilic (water-attracting) PEG segments and lipophilic (oil-attracting) hydrocarbon chains, allowing it to act as an exceptional emulsifier and surfactant. This semi-solid ester is prized for its ability to modify the properties of other ingredients, primarily by reducing surface tension and stabilizing mixtures that would otherwise separate.
