What molecules make up the vegetable oil of plum?

Its biochemical composition makes theplum oil a prime ally for protecting the skin and hair from photoaging related to free radical damage. Discover in this article its main constituents and their benefits.

What is the mass distribution of fatty acids in plum oil?

Like most vegetable oils, plum oil is primarily composed of fatty acids. Its composition includes:

  • The monounsaturated fatty acids such as oleic acid (also known as omega 9), present in a mass fraction ranging from 65 to 75%. Although synthesised by the body, external supply (topically) of omega 9 is necessary to strengthen the skin's protective barrier. Indeed, these fatty acids constitute the hydrolipidic film, the layer that protects the skin from aggressions and maintains its hydration level. These are lipids that are part of the composition of sebum, a substance naturally secreted by the body to counteract skin and hair dryness. To avoid brittle hair and dry skin, sufficient sebum production is necessary. Oleic acid thus stimulates the production of sebum by the sebaceous glands and fights against the dryness of the hair and skin.

  • The polyunsaturated fatty acids, including the linoleic acid or omega 6, are present in a mass fraction ranging between 15 and 25%. This category of fatty acids is referred to as essential, as they are not synthesised by the body. Omega 6 contributes to the process of cellular renewal. When applied topically, they help combat signs of ageing and promote healing. They also soothe inflammatory reactions and are beneficial for sensitive skin, suffering from tightness and irritation.

  • The saturated fatty acids, such as the palmitic acid, account for 4 to 6% of the total composition of plum oil. Palmitic acid has emollient properties, which means it promotes hydration of skin and hair cells. It thus provides suppleness and softness.

Note: Due to the chemical structure of these fatty acids, vegetable oils are sensitive to oxidation, it is recommended to store them away from light and moisture. Furthermore, close the bottle after each use.

The unsaponifiables of plum oil.

As the name suggests, the "unsaponifiable" fraction of a vegetable oil represents the elements that are not transformed into soap during a saponification reaction. These include sterols, hydrocarbons (squalene, etc...), fatty alcohols (waxes, etc...), liposoluble pigments, vitamins, polyphenols, minerals, etc... Generally, this unsaponifiable fraction only accounts for 0.5 to 2% of vegetable oils.

Plum oil contains a proportion > 600 mg/kg of vitamin E (tocopherol), a powerfulnatural antioxidant. It protects the skin and hair from the damage caused by free radicals, which arereactive oxygen speciesproduced naturally by the body but produced in excess when cells are exposed tostress. The sources of stress are numerous, the main ones being UV exposure, pollution, smoking, a diet too rich in fats and/or sugars. Free radicals are particularly unstable molecules due to theirsingle electron. They tend to react with other molecules to form apair of electrons, and then causedamage to cells, DNA, and the body's proteins. They are notably involved in lipid peroxidation, a degradation reaction of the constituents of cell membranes. This accelerates ageing and wrinkles appear on the skin's surface. Regarding hair, free radicals weaken hair fibres, hastening their fall and/or the appearance of white hair. Plum oil is therefore an excellent ally in preventing skin ageing, combating the appearance and/or accentuation of wrinkles, as well as the degradation of hair strength over time.

Discover Typology's Vegetable Prune Oil

Ourplum vegetable oilcomes from the cold pressing of plum kernels fromorganic farming, grown and harvested in theSouth-West of France. By replenishing the skin's lipid layer, this treatment nourishes, hydrates and improves skin elasticity. It also protects it from the harmful effects of pollution, including cellular oxidation.
