Additionally, its surfactant-cleansing capabilities make it a popular choice in formulations aimed at providing a refreshing and clean feel.

GLYCERYL STEARATE is a versatile ingredient commonly used in cosmetic formulations for its properties as a skin-conditioning emollient and surfactant-emulsifying agent. It helps to improve the texture and feel of products by providing a smooth, moisturizing effect on the skin, making it an ideal choice for creams and lotions. Additionally, it aids in the emulsification process, allowing oil and water components to blend effectively, which enhances the stability and performance of the formulation. Formulators may add GLYCERYL STEARATE to achieve a desirable consistency and to enhance the overall sensory experience of the product.

KAOLIN is a versatile cosmetic ingredient with several functions. As an abrasive, it can provide a scrubbing action in formulations, which may be useful for exfoliation. Its absorbent properties allow it to take up moisture or oils, making it beneficial in products designed to manage excess sebum. Additionally, KAOLIN serves as an anticaking agent, helping to prevent clumping in powdered formulations. It can also act as a bulking agent, contributing to the texture and volume of products. Furthermore, KAOLIN can function as a colorant, adding visual appeal, and as an opacifying agent, which can enhance the opacity of formulations, making them less transparent.

Phenoxyethanol is a widely used cosmetic ingredient recognized for its role as a preservative. It helps to prevent the growth of bacteria, mold, and yeast in cosmetic formulations, thereby extending the shelf life of products and ensuring their safety for consumers. Formulators may add Phenoxyethanol to protect the integrity of the product and maintain its effectiveness over time, especially in water-based formulations where microbial growth is a concern.

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.

TETRASODIUM EDTA is a chelating agent commonly used in cosmetic formulations. Its primary function is to bind metal ions, which can help to prevent these ions from interacting with other ingredients in the formulation. This is particularly important in products where metal ions might cause instability or undesirable reactions, thereby enhancing the overall efficacy and stability of the product. Formulators may add TETRASODIUM EDTA to improve the longevity and performance of their formulations by minimizing the effects of hard water and other impurities that could compromise the product's integrity.

PEG-14M is a cosmetic ingredient that serves multiple functions, including binding, emulsion-stabilising, and viscosity-controlling.
