Key Features & Benefits
pH Balancing: These washes are typically formulated with a pH of 4.5 to 5 to match and help maintain the natural pH balance of the external intimate area, which can be disrupted by regular alkaline soaps.
Odor Elimination: Natural ingredients and essential oils (like rose, lavender, or pineapple) are included to help remove odors, leaving a fresh scent.
Soothing & Moisturizing: They are designed to ease discomfort, irritation, and itchiness, and keep the skin moisturized and hydrated.
Natural/Organic Ingredients: Many of these products are made from natural, plant-based, and organic ingredients, such as aloe vera extract, coconut oil derivatives, chamomile extract, and various essential oils, often free from harsh chemicals, sulfates, dyes, and parabens. 
Ingredients
Ingredients vary by specific brand, but common components may include: 
Water/Aqua
Aloe Vera Juice: Often a primary ingredient, known for its hydrating and calming properties.
Chamomile Extract: Included for its soothing properties to reduce itchiness and irritation.
Lactic Acid: Helps maintain a balanced pH level.
Natural Oils/Extracts: Rose oil/petals, peppermint oil, safflower oil, and jojoba oil are common additions for scent and skin benefits.
Gentle Cleansing Agents: Ingredients like cocamidopropyl betaine or hydrolyzed oat protein are used as mild cleansers instead of harsh sulfates found in many standard soaps. 
Usage
For best results, use a small amount on damp skin in the shower or bath, gently massage the external area (the vulva), and rinse thoroughly with clean water. The washes are gentle enough for daily use, particularly after workouts or during the menstrual cycle. 
Expert Opinion on Safety
While these products are marketed as natural and safe, medical experts often recommend using only clean water to cleanse the vulva, as even mild products can potentially disrupt the natural bacterial balance and pH levels. Some studies have found a correlation between the use of intimate washes and a higher risk of certain infections, though this may be due to women using the products to address pre-existing symptoms. It is advisable to consult a doctor before adding any new product to your intimate care routine.
