Peroxydation et réaction intra-moléculaire Les huiles d’olive deviennent rance au cours du temps. Le rancissement est une modification chimique des structures moléculaire des huiles végétales. Les mêmes mécanismes chimiques opèrent aussi sur les huiles essentielles. La présence d’oxygène naturellement dissous dans les huiles, initie ces réactions chimiques. Elles s’accélèrent en présence de lumière, d’air, de sauts de température ou de diverses impuretés. Le mécanisme réactionnel de ce « vieillissement » se divise en deux étapes: la peroxydation et les réactions intramoléculaires (ou phase de propagation). La littérature scientifique décrit plusieurs exemples de peroxydation. Voici celui du linalol abondemment présent dans les huiles essentielles. (Exemple: lavande, lavandin, thym à linalol, bois de rose, sauge sclarée, etc). Dans ce shéma, le linalol subit en premier une peroxydation. Elle produit un nouveau composé: le 7-dydroperoxy-3,7-dimethyl-octa-1,5-diene-3-ol.

is a sodium salt of the lactic acid. Sodium lactate belongs to the group of hydrating substances for the skin, that keeps the skin-own moisture and contributes to a slightly acidic pH value. The substances (glycerine, urea and organic acid) form together the Natural Moisturing Factor(NMF). In the EU sodium lactate is known as food additive E 325. The salt is easily soluble in water. The fluid is almost colourless and almost without scent or taste. Sodium lactate is also available in various concentrations (50 % / 60 %), on demand with adjusted pH value.

Hydroquinone is produced as an inhibitor, an antioxidant, and an intermediate in the synthesis of dyes, motor fuels, and oils; in photographic processing; and naturally in certain plant species, Hydroquinone is a phenol derivative with antioxidant properties that can cause toxicity in several organs, notably the kidney. Used as a topical treatment for skin hyperpigmentation and in various cosmetic products, it is metabolized mainly to glutathione conjugates and forms mutagenic DNA adducts in in-vitro systems. (NCI04)
