Why is cream milky white?
No matter which brand of cream, their main ingredients are oil and water. No matter what kind of cream it is, the top ingredients in the ingredient list are water and oil, and they are all transparent. But why is the cream milky white? Because the emulsifier is added, one end of it is hydrophilic and the other end is lipophilic. Emulsifier molecules are closely arranged on the oil-water interface to form a protective film, which prevents droplets from automatically gathering and stabilizes the emulsion. Oil is dispersed into fine particles and becomes milky white under the refraction of light.
The main technology of cream
Water-in-oil and oil-in-water are introduced respectively:
1, the solid powder that is easily wetted by oil is beneficial to form W/O (water-in-oil) emulsion, that is, water-in-oil emulsion; Solid powder that is easily wetted by water is beneficial to the formation of O/W (oil-in-water) emulsion, that is, oil-in-water emulsion. Water-in-oil type contains more oil and less water. The oily ingredients cover the water-based ingredients, and the external phase is mostly oily cream, which feels thicker and more sealed when applied, and can lock the water from losing. The names of skin care products with the words "face cream" and "face cream" on the market are mostly places where water is in oil. Conducive to locking water and moisturizing, strengthening skin barrier and resisting external invasion. When sunscreen and foundation cream are used, manufacturers usually use water-in-oil carriers for fear of sweating.
2. The oil-in-water type usually has a relatively high water content and a relatively low oil content. Water-based components are coated with oily components, and the external phase is mostly water-phase liquid, which makes it feel refreshing to use. The names of skin care products with the words "milk", "dew" and "honey" on the market are mostly oil-in-water texture. The texture is light, refreshing and translucent, and the specific gravity of water is greater than that of oil. A drop of water, usually "oil-in-water", will float on the water surface, and it will slowly dissolve into milky white with a little stirring. On the contrary, most "water-in-oil" emulsions or creams will sink under the water surface and are not easily soluble in water.
How to choose water-in-oil and oil-in-water
Oil-in-water and water-in-oil are only different in the proportion of oil and water in skin care products, so the texture looks different. We should choose different types according to different skin needs:
1, dry skin has fine pores, and dry skin is prone to dry lines and wrinkles. Skin care products should use water-in-oil cold cream. After application, water will penetrate into the skin, making the skin moist and refreshing. Oily components can form an oil film on the skin surface, which has good moisturizing, softening and moisturizing effects on the skin. Neutral skin is smooth and delicate. Choosing oil-in-water cream skin care products can form an isolation film on the skin surface, which can isolate the skin from the outside air, control the excessive discharge of epidermal moisture, regulate and protect the stratum corneum, and make it contain appropriate moisture, which plays an important role in the softness, elasticity and health of the skin.
2. Oily skin has rough surface and obvious pores, and it is easy to produce closed mouth and acne. Choose refreshing and moisturizing skin care products or oil-in-water emulsion, which has a good moisturizing effect on the skin.
