Overview of the Composition of Cosmetic Preparations for Intimate Hygiene

A number of products for maintaining intimate hygiene are available on the market. They consist of a blend of components intended to cleanse, care for and protect the area of application, and support its microbiological balance. The present study reviews the compositions of international intimate hygiene product brands currently available in Poland (within the European Union) and the frequency of their components: their surfactants, plant extracts, prebiotics, postbiotics and skin care agents. The most popular surfactants in rinse-off products for women were Cocamidopropyl Betaine, present in 72% of products, followed by Coco-Glucoside (58%) and Sodium Laureth Sulfate (24%). Similarly, in the products for girls, the most common were Cocamidopropyl Betaine (55%), Lauryl Glucoside (45%), Coco-Glucoside (40%) and Sodium Laureth Sulfate (20%). The intimate wipes contained mainly nonionic surfactants: PEG-40 Hydrogenated Castor Oil (28%), Coco-Glucoside and Polysorbate 20 (20% each). Many components with protective and caring properties were identified: plant extracts (e.g., Aloe Barbadensis Leaf Juice, Chamomilla Recutita Flower Extract), prebiotics (Inulin, Alpha-Glucan Oligosaccharide) and postbiotics (Lactobacillus Ferment, Leuconostoc/Radish Root Ferment Filtrate), as well as Lactic Acid, Glycerin, Citric Acid, Panthenol and Allantoin.
