Which component is often included in massage oil or cream?

The inclusion of perfume in massage oil or cream serves multiple functions. Primarily, it enhances the sensory experience and overall enjoyment of the massage. A pleasant fragrance can help create a calming and relaxing atmosphere, which is essential for therapeutic practices. Additionally, fragrance can stimulate positive emotional responses and improve mood, aiding the overall effectiveness of the treatment.

In contrast, acetone is commonly used as a solvent in nail polish removers and is not suitable for skin application due to its drying and irritating properties. Formaldehyde, often found in certain cosmetic products, is recognized for its strong odor and potential health risks, making it inappropriate for massage oils. Sodium chloride, or table salt, may be used in some skin treatments but is not a typical component in massage oils or creams, as it can be abrasive and drying to the skin rather than hydrating. Thus, perfume stands out as the most relevant and beneficial component among the choices provided for massage products.
