Petroleum jelly plastics and minimize ventilation issues, isopropyl (rubbing) alcohol can be used to remove petroleum jelly from most surfaces. Isopropyl alcohol is inert to most household surfaces, including almost every plastic, and removes petroleum jelly efficiently. While alcohol causes fewer ventilation problems than petroleum solvents, ventilation is still recommended, especially if large surface areas are involved. Petroleum jelly is also soluble in lower-molecular-weight oils. Using an oil to dissolve the petroleum jelly first can render it more soluble to solvents and soaps that would not dissolve pure petroleum jelly. Vegetable oils such as canola and olive oil are commonly used to
Major royal jelly protein Major royal jelly protein Major royal jelly proteins (MRJPs) are a family of proteins secreted by honey bee. The family consists of nine proteins, of which MRJP1 (also called royalactin), MRJP2, MRJP3, MRJP4, and MRJP5 are present in the royal jelly secreted by worker bees. MRJP1 is the most abundant, and largest in volume. The five proteins constitute 82-90% of the total proteins in a royal jelly. Royal jelly is a nutrient-rich mixture of vitamins, sugars, fats, proteins and enzymes. It is used for feeding the larvae. Royal jelly has been used in traditional medicine since ancient times, and the
