A glyceride is a combination of glycerol with fatty acids, a so-called ester.
It is not repellent, it is some form of lard or long chain poly-glyceride that one goops onto the skin.
The Goal: Chemically speaking, vegetable oil is a tri-glyceride.
Conventional oilseed crops, such as soybean, corn, olive, and peanut, produce glyceride oils, in which fatty acids are connected to a glycerol molecule.
KALICKOV, M. and HADZIJSKI, Cv. (1963) An investigation of Fructus anisi and its essential and glyceride oils.
Ordinary milling soap is used as a basis for this soap; the settled soap direct from the copper at 170° F. (77° C.) is carefully neutralised with bicarbonate of sodium, oleic or stearic acids, or boro-glyceride, perfumed and aerated.
It was formerly considered that the three acid radicles in any naturally occurring glyceride were identical, corresponding to the formula --
All oils and fats contain more or less free acidity; but excess of acidity, though it may be due to the decomposition of the glyceride, and does not always denote rancidity, is undesirable in soap-making material.
By this method, sulpho-compounds of the glyceride are first formed, which readily emulsify with water, and, on treatment with steam, liberate fatty acids, the glycerol remaining partly in the form of glycero-sulphuric acid.
The first mixed glyceride to be discovered was oleodistearin,
