Lavender pillow sprays typically use lavender essential oil (Lavandula angustifolia) often blended with other calming botanicals such as chamomile or ylang ylang. Ingredient lists commonly include a carrier (for example alcohol denat. or glycerin) and preservatives like phenoxyethanol.
Scent longevity varies by product and usage. Many users report the aroma lasting around 24 hours, with some products noted to linger up to about 48 hours.
Beyond fragrance, some lavender sprays also disinfect or sanitize soft surfaces, neutralize fabric odors, or neutralize allergens on contact, depending on the product formulation.
