Mechanism of Dry Shampoo in Synergistic Oil Removal

In addition to surfactants as the primary agents, the adsorbent powders in dry shampoo formulations, such as corn starch, rice starch, or silica, also play a crucial role. These porous powders possess a large specific surface area, functioning like sponges to physically absorb oils and moisture. Combined with the chemical adsorption of surfactants, they provide a dual mechanism to quickly eliminate greasiness from the hair.

Propellant (e.g.,LPGIn aerosol dry shampoo, it is responsible for delivering the contents in a uniform and fine spray, ensuring that active ingredients fully cover the hair roots and scalp area. Meanwhile, conditioning components (such as silicone oil or plant extracts) work to smooth the hair cuticles, reduce static electricity, and enhance the smoothness of the hair strands while removing oil. This prevents dryness and frizz after cleansing, thereby improving the user experience.

From"Recipe—Mechanism of action—Experience"From a product perspective, this is a typical synergistic process: surfactants and adsorbent powders are responsible for precisely capturing and locking in oil (mechanism of action), propellants ensure effective delivery (formulation design), and conditioning agents work to repair and enhance texture (final experience). Users simply need to spray and gently massage, and within minutes, their hair regains its fresh, voluminous bounce—all thanks to the coordinated efforts of each component working in harmony.
