Product Insights
Cosmia's Instant Voluptueux is a 750 ml dual shower-and-bath gel marketed in French retailers such as Auchan, formulated primarily with water, sodium laureth sulfate surfactants and the humectant glycerin. The formulation delivers a rich lather and added moisturization thanks to glycerin and cocamidopropyl betaine, while also incorporating sodium chloride for viscosity, citric acid for pH balance, and a synthetic fragrance preserved with sodium benzoate. However, it contains potential irritants, including the strong surfactant sodium laureth sulfate, fragrance allergens like hexyl cinnamal, linalool and alpha-isomethyl ionone, and synthetic dyes (CI 60730, CI 17200, CI 28440), which may not be suitable for sensitive or allergy-prone skin.
Comparative Analysis
Targeting the mass-market segment, this affordable large-volume gel distinguishes itself with a luxurious scent and moisturizing glycerin, yet it relies on conventional surfactants and synthetic additives rather than natural or eco-certified ingredients.
