Man labai reikia greipfrukto seklu ekstrakto!!!
Vaistinėje - "Citrosept"
'Natūralus' greit prarūgtų
Todėl išgaunant šį ekstraktą deda konservuojančias ir antimikrobines medžiagas - triklosaną, benzetonio ir benzalkonio chloridus, net metilparabeną pan.
Ženklinime nurodyti nebūtina
, ale 'sustiprina' antimikrobinį-antivirusinį sėklų ekstrakto poveikį (kuriuo realybėje šis ekstraktas kiek bebūtų tirtas - nepasižymi
Skaičiau kelis mokslinius straipsnius prieš kelis metus - buvau lengvai tariant šokiruota..

Įdomu kas jį išgauna

"
Recent studies have identified synthetic preservatives in commercial grapefruit seed extracts.[4][5][6]
When preservatives were not present in some of the extracts, laboratory tests found the natural extracts had no natural antimicrobial attributes of their own.[3]
Some manufacturers of GSE have stated that their extract has compounds nearly identical to benzethonium chloride but a 2001 study supervised by chemist G. Takeoka has documented that commercial GSE preparations contain the synthetic compound benzethonium chloride that couldn't have been made from GSE.[3]"
