In cosmetics, starch is a common ingredient with diverse functions, utilized in various types of products. Here are the primary roles of starch in cosmetics:
-
Oil Absorption and Control: Starch exhibits excellent oil-absorbing properties, making it a common addition to formulations aimed at controlling surface sebum. In products like face powders and loose powders, starch helps absorb excess oil, ensuring makeup durability and minimizing shine.
-
Texture Improvement and Spreadability: Starch serves as a diluent in cosmetics, enhancing product texture for easy application and spreadability. This is particularly important for products like foundations and eyeshadows that require even application.
-
Enhancing Transparency: The addition of starch can increase the transparency of cosmetic products, providing a natural and radiant appearance to the skin. This is often employed in products like setting powders to create a three-dimensional effect and a natural glow.
-
Humectant Properties: Starch possesses a degree of humectancy, aiding in maintaining skin hydration. Adding starch to products such as foundations and pressed powders helps prevent excessive dryness of the skin.
-
Reducing Friction and Adhesion: The silky texture of starch contributes to reducing friction between cosmetics and the skin, preventing product clumping. This is beneficial for products like lip balms and sunscreens, enhancing user experience.
-
Moisture Absorption: Starch's ability to absorb moisture is harnessed in cosmetics to maintain the balance of skin hydration. This is particularly useful in formulations like foundations and powder compacts.
-
Improving Concealing Effects: Incorporating starch into concealers, foundations, and other coverage products aids in even color distribution, enhancing concealing effects and achieving a more natural makeup look.
In conclusion, starch plays a pivotal and versatile role in cosmetics, offering functional benefits across a range of products. Its multifaceted properties contribute to the effectiveness, texture, and overall user experience in various cosmetic formulations
