As people pay more and more attention to skin care, the cosmetics industry continues to pursue higher quality and more efficient ingredients. As a natural and versatile raw material, fatty acid powder has gradually emerged in the cosmetics field and plays an important role.
1.Emulsification
Among many cosmetics, products such as lotions and creams require the oil phase and the water phase to be evenly mixed to form a stable emulsified system. Fatty acid powder has excellent emulsification properties and can reduce the surface tension of the oil-water interface so that the two are closely combined. For example, in a moisturizing cream, fatty acid powder can help oil and water disperse evenly, making the cream texture more delicate, easy to spread when applied, and improving the feel of use. Moreover, a stable emulsification system helps to extend the shelf life of the product and ensure that the cream will not separate oil and water during storage.
2.Moisturizing
Retaining moisture in the skin is essential for maintaining skin health. The long-chain fatty acids in fatty acid powder can form a thin protective film on the surface of the skin, which can prevent the loss of moisture inside the skin and play a moisturizing role. At the same time, it can also increase the softness and smoothness of the skin, making the skin feel more delicate. For example, in some skin care products suitable for dry skin, fatty acid powder can work synergistically with other moisturizing ingredients to enhance the moisturizing effect and keep the skin moisturized for a long time.
3.Regulating the pH value of the skin
The surface of the skin has a natural weak acidic environment, and the pH value is usually between 4.5 and 6.5. This environment helps to maintain the barrier function and microbial balance of the skin. Fatty acid powder has a certain acid-base regulating ability, which can help cosmetics adjust to a range close to the pH value of the skin and reduce irritation to the skin. For example, adding fatty acid powder to cleansing products can enable the product to better protect the acid-base balance of the skin while cleaning the skin, and avoid damage to the skin barrier caused by excessive cleaning.
