Cosmetic effect of coconut oil

In coconut oil, the saturated fat content was up to 90%, so coconut oil's melting point is higher than the melting point of common edible oils, it itself at room temperature is solid. Apart from the saturated fatty acid esters, coconut oil also contains small amounts of unsaturated fatty acid esters, free fatty acids such as lauric acid and other ingredients.

Most people use coconut oil on the skin to maintain moisture. We should know that, the less water content of the stratum corneum, the skin will more dry; if reduce water losing from the stratum corneum, the skin's dry condition can be improved. 85% or more components of coconut oil are a lot of saturated fatty acid esters, the closed skin effect is similar to petrolatum, mineral oil, can reduce transepidermal water losing, play a moisturizing effect. Coconut oil also can increase the skin surface lipids, soft skin. That is to say coconut oil is only a humectant. While substances which really have nutritional function to skin such as unsaturated fatty acids, vitamin E and the like are accounted for very small amounts in coconut oil, so coconut oil is not anti-aging, removing wrinkles and other skin care effects.

Directly applied the coconut oil, especially unrefined coconut oil to the face or hands may be risky. Free lactic acid contained in coconut oil may cause irritation to the skin. Studies have shown that lauric acid has small molecular weight, can easily be dissolved in the lipid phase and permeate the membrane, physical damage to the cells, and inhibit the production energy and transfer nutrients enzymes, resulting in reversible and irreversible changes, lead to cell death. Only the lauric acid reacted with diethanolamine to produce Coconutt Diethanol Amide can be used as cosmetic additives.

Coconut oil is important indirect materials in the cosmetics industry, such as for soap industry. Coconut oil's saponification value is higher than other common vegetable oils, freezing point in 21~25, made of soap would not too soft, and foaming well, very suitable for simple hand cold soap. Of course, this handmade soap is not healthier than ordinary soap.

Hair is divided into three kinds from outside to inside, namely, hair cuticle, hair cortex and medulla hair, whose main ingredient is keratin. Damaged hair mainly refers to the cuticle under physical and chemical action, generates friction, deformation, while the coconut oil conditioner role is reflected in its attentive care on keratin. For all kinds of hair types, coconut oil has prevented combing injury effect. It can form lubricating film on the surface of the hair, reduces the friction between the hair cuticle, even have the effect on damaged hair.

Used coconut oil before the washing hair, it can form a hydrophobic film on the keratin edge, prevent hair absorbing water; and it can penetrate into the hair, reducing the swelling extent of keratin. Hair absorbs less water, hair cuticle deformation and friction damaged will be reduced, the hair is protected. Lauric acid in coconut oil has a strong affinity to keratin, meanwhile it is amylose molecules of small molecular weight, which can permeate the hair fiber. Mineral oil and other vegetable oils cannot penetrate into the hair.

All in all, coconut oil is a good cosmetic raw material, but it should not be given too much expectations, it cannot anti-aging also can not remove wrinkles.
