At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on providing ingredients that are backed by solid science. Cinnamic Acid Powder is a prime example, demonstrating remarkable efficacy as a UV absorber, a crucial function for modern sunscreen formulations. Understanding the science behind its action reveals why it is such a valued cosmetic raw material.

The efficacy of Cinnamic Acid as a UV absorber lies in its molecular structure, specifically its conjugated pi system. This structure allows the molecule to absorb energy from ultraviolet radiation. When UV photons strike the Cinnamic Acid molecule, the energy excites electrons within the molecule, typically from a ground state to a higher energy state. As the molecule returns to its ground state, it dissipates this energy harmlessly, often as heat, thereby preventing the UV radiation from reaching and damaging the skin cells. This process effectively filters out harmful UV rays, acting as a protective shield.

Research has shown that Cinnamic Acid and its derivatives are particularly effective at absorbing UVB radiation, which is a primary cause of sunburn. Some derivatives also offer protection against UVA radiation, which contributes to premature skin aging and deeper skin damage. This broad-spectrum absorption capability makes Cinnamic Acid a highly versatile ingredient for sun care products. Its photochemical stability, though sometimes enhanced with stabilizers, ensures that it continues to provide protection over time.

The development of advanced sunscreens relies on ingredients like Cinnamic Acid that offer robust UV protection. Its ability to absorb harmful UV light, coupled with its other beneficial properties like fragrance and antioxidant effects, solidifies its position as an essential component in cosmetic formulations. We are dedicated to supplying high-purity Cinnamic Acid Powder to manufacturers who seek scientifically proven ingredients to create effective and reliable sun protection products.

By leveraging the chemical properties of Cinnamic Acid, formulators can create sunscreens that offer superior protection against the damaging effects of the sun. Its role as a UV absorber is a testament to its scientific utility and its contribution to public health by reducing the incidence of sun-related skin damage.
