Its chelating function allows it to bind metal ions, which can enhance the overall performance and longevity of the formulation by preventing the degradation of other ingredients. Additionally, CITRIC ACID can contribute to the fragrance profile of a product, adding to the sensory experience of the user. Formulators may include CITRIC ACID to improve product stability and enhance the overall user experience.

PSEUDOALTEROMONAS FERMENT EXTRACT is a biotechnologically derived ingredient obtained from the fermentation of the marine bacterium Pseudoalteromonas. It is primarily used as a humectant in cosmetic formulations, meaning it helps to attract and retain moisture in the skin. This characteristic makes it beneficial for enhancing skin hydration and maintaining a healthy skin barrier. Formulators may add PSEUDOALTEROMONAS FERMENT EXTRACT to products to improve their moisturizing properties and to provide a more supple feel to the skin, leveraging its natural origin and biocompatibility.

Sodium Hyaluronate is the sodium salt of hyaluronic acid, a naturally occurring substance in the body known for its remarkable ability to retain moisture. As a humectant, it attracts and binds water to the skin, helping to maintain hydration and improve the skin's overall texture and appearance. Formulators often include Sodium Hyaluronate in cosmetic products to enhance moisture levels, promote a plump and youthful look, and provide a smooth application experience. Its lightweight nature allows for easy absorption, making it a popular choice in various skincare formulations.

Caprylyl Glycol is a multifunctional ingredient commonly used in cosmetics for its preservative and humectant properties. As a preservative, it helps to inhibit the growth of microorganisms, thereby extending the shelf life of cosmetic products. Its humectant function allows it to attract and retain moisture in the skin, contributing to hydration and a smoother appearance. Formulators may add Caprylyl Glycol to enhance product stability and improve the overall sensory experience of the formulation.

CARBOMER is a synthetic polymer commonly used in cosmetic formulations for its ability to stabilize emulsions, form gels, and control viscosity. It helps to create a desirable texture in products, making them easier to apply and enhancing their overall feel on the skin. Formulators may add CARBOMER to achieve specific consistencies and stability in creams, lotions, and gels, ensuring that the ingredients remain evenly distributed and effective throughout the product's shelf life.
