Underwear is a type of clothing that comes into direct contact with sensitive skin, which is prone to irritation and infection if not washed properly. However, many people still use the same washing powder or regular detergent for all types of clothing, including underwear. This seems convenient but poses many health risks.
So, should you use a separate underwear detergent? And what kind of detergent is really good and safe for users? This article will help you clarify the importance of washing underwear specifically and suggest reliable products.
Using specialized underwear detergent is a way to protect your health and take care of yourself scientifically. Here are the main reasons:

Prevent bacteria and fungi that cause disease: Underwear is in direct contact with the humid environment of the private area, easily accumulating bacteria and yeast (such as Candida, E.coli) causing inflammation, itching, and unpleasant odors. Specialized underwear detergents often have stronger antibacterial and antifungal formulas than regular detergents, helping to completely destroy these pathogens.
Avoid irritating sensitive skin: The intimate area is an extremely sensitive area. Regular laundry detergents can contain harsh chemicals, synthetic fragrances, or bleach that can easily cause irritation, rashes, and even contact dermatitis. The product is designed with a gentle formula and suitable pH level to minimize the risk of irritation.
Underwear often has typical stains such as body fluids, menstrual blood, sweat. Detergents for sensitive skin are formulated to easily and effectively remove these stains without too much rubbing, keeping underwear always clean and fresh.
Lingerie is often made from soft, delicate materials such as lace, silk, cotton, and synthetic fibers. Regular laundry detergent with strong detergents can damage the fabric structure, causing the lingerie to stretch, fluff, fade, or stiffen. Special laundry detergent products have a gentle formula, helping to maintain the shape, elasticity, and color of lingerie for longer.
Washing underwear with other types of clothing (especially outerwear, work clothes, children’s clothes) can accidentally transfer bacteria from these fabrics to underwear and vice versa. Washing separately and using detergent specifically for underwear helps to minimize the risk of cross-contamination.
Outstanding antibacterial and antifungal properties
This is the most important factor. The product must be able to kill bacteria and yeast that cause common gynecological diseases such as Candida, E.coli, Staphylococcus aureus… Look for products that are certified by reputable medical and testing organizations (e.g. Pasteur Institute, Quatest).
Safe, gentle ingredients
Harsh Chemical Free: Stay away from Chlorine, parabens, colorants, fluorescents, phosphors, harsh bleaches.
Balanced pH: You should choose a type with a pH that matches the physiological pH of the vaginal area (usually neutral or slightly acidic pH) to avoid causing an imbalance in the vaginal environment.
Prioritize natural extracts: Aloe vera, green tea, tea tree oil… both help clean and have natural antibacterial properties.
Mild or no fragrance
Synthetic fragrances are common irritants. It’s best to choose unscented or very mild, natural-scented lingerie detergents to avoid irritation or allergic reactions in sensitive areas.
Rinses easily, leaving no residue
The product must be easily soluble in water and not leave soap residue on underwear after washing, avoiding itching and allergies.
Suitable for both hand and machine washing
Many people have the habit of washing underwear by hand to ensure cleanliness and keep the shape. Therefore, the product should have a moderate foaming formula, easy to handle when washing by hand.
