Additionally, water can help to hydrate the skin, making it a vital component in many moisturizing formulations.

Cocamidopropyl Betaine is an ingredient classified as a surfactant. Surfactants are compounds that can reduce surface tension between two substances, which can enhance the mixing and dispersing of ingredients in a formulation.

Its primary function is to enhance the sensory experience of a product, making it more appealing to consumers. Formulators may add Fragrance to mask the natural odors of other ingredients or to create a signature scent that differentiates a product in the market. However, it's important to note that Fragrance can be a potential irritant for some individuals, which is a consideration for formulators when developing products.

SODIUM CHLORIDE, commonly known as table salt, is a versatile ingredient used in cosmetics for various functions. It acts as a bulking agent, helping to increase the volume of formulations without significantly altering their properties. Additionally, it can serve as a viscosity-controlling agent, allowing formulators to adjust the thickness of products to achieve desired textures. In some cases, it may also enhance fragrance stability or contribute to oral-care formulations. Due to its multifaceted roles, SODIUM CHLORIDE is a valuable component in the development of a wide range of cosmetic products.

Citric Acid is an organic acid commonly found in citrus fruits and is widely used in cosmetic formulations for its multifunctional properties.

Formulators may add Citric Acid to enhance the overall efficacy of a product and to improve its stability.

Its effectiveness and low toxicity make it a popular choice in various cosmetic applications.

Limonene is a naturally occurring compound found in the peels of citrus fruits, and it is commonly used in cosmetics primarily for its pleasant fragrance. As a fragrance-allergen, it can enhance the sensory experience of a product, making it more appealing to consumers.

However, it is important to note that Limonene can also act as a potential irritant for some individuals, which is why its use is often accompanied by caution in formulations.

LINALOOL is a naturally occurring terpene alcohol found in many flowers and spice plants. It is primarily used in cosmetics for its deodorant and perfuming properties, providing a pleasant fragrance and enhancing the overall sensory experience of a product.
