Virgin olive oil is a type of edible oil derived from the fruit of the olive tree (Olea europaea). It is one of the most commonly used cooking oils and is known for its health benefits. Virgin olive oil is obtained through mechanical pressing or centrifugation of olives, without the use of heat or chemicals. It is categorised into different grades, with extra virgin olive oil being the highest quality and most prized for its flavour and health benefits.
The use of products derived from Almond originated with the ancient Hindus, who used crushed Almond paste as a cleanser. Today, wide varieties of Almond derivatives are used in cosmetics and personal care products.
Virgin olive oil primarily consists of various fatty acids, with oleic acid being the predominant one. Oleic acid is a monounsaturated fat and is considered to be heart-healthy. Other fatty acids present in smaller amounts include linoleic acid (a polyunsaturated fat) and saturated fats like palmitic acid and stearic acid.
Virgin olive oil contains a variety of antioxidants, including tocopherols (vitamin E), phenolic compounds (such as hydroxytyrosol and oleuropein), and carotenoids (including beta-carotene). These antioxidants help protect the oil from oxidative damage and provide potential health benefits.
Almond oil is a valuable addition for both soap-makers and cosmetic chemists and can be useful in many formulations, including creams, facial oils, massage oils, soap, salves, balms and lotions.
Almond oil can help prevent trans-epidermal water loss and assists in retaining water on the skin. Topical use creates an occlusive barrier in the skin, which can still be visible 2-3 days after application. Given its high percentages of Oleic (70%) and Linoleic (20%) acids, almond oil can penetrates the skin at a moderate rate, and can be beneficial as a skin lubricant and emoillient.
In general, nuts, seeds, and legumes are excellent sources of phytosterols, both for the body and for skin. Phytosterols can help replenish and restore ageing skin, keeping it pliant and supple.
Almond oil is insoluble in water and alchohol, but soluble in other oils. It should be added to the formula as is, in the fat phase of the formulation, and can be used at 1-100%, as it can be used neat in massage oils.
