Palm stearin derived from the palm oil by processing the oil at controlled temperature with the partial crystallization method, then the solid fraction of the palm oil is derived called palm stearin.
What are stearin candles made of?
Stearin candles are a sustainable alternative to conventional paraffin candles. Stearin is obtained from vegetable or animal fats and oils. In terms of quality stearin candles are considered to be of higher quality, which is also noticeable in their weight – they are considerably heavier.
What is the difference between oil and olein?
The palm olein has different characteristics than the palm oil, most notably that it remains completely liquid at room temperature. It is highly heat resistant, similar to palm oil, and it also resists the formation of breakdown products during frying and increases the shelf life of many products.
What are the three methods of olein and stearin?
The three methods—dry , detergent, and the wet fractionation process —produce both olein and stearin fractions that are distinct from each other. Even the slow versus rapid chilling under dry fractionation produces distinct products.
What is palmkernel stearin?
Palmkernel stearin is a material of choice in the manufacture of compounds for moulding and coatings. Quality is generally assessed in terms of high SCF levels at 20 and 25 °C and low levels at 35 °C, in order to ensure a good ‘snap’, good fingerprint resistance and good melting down. Hydrogenation of palmkernel stearin affects its melting point and SFC at 35 °C: 18:1 and 18:2 contents are lowered while the content of 18:0 is increased. The crystal structure of substitute chocolate manufactured with hydrogenated palmkernel stearin is finer than if it is made with the nonhydrogenated fraction. Chocolate products made with hydrogenated palmkernel stearin melt rapidly at mouth temperature and do not melt at finger temperature.
What is the melting point of palm stearin?
There are three types of palm stearins—soft, hard, and very hard—available on the market. Soft palm stearins (melting point of 40–46 °C) are obtained through single fractionation of palm oil or double fractionation of palm olein (Rashid et al., 2011 ). These fractions are commonly used as the main components in shortenings ...

What is stearin used for?
Strearin (glyceryl tristearate) is a triglyceride, which is a derivative of stearic acid (Triglycerides are typically taken from a minimum of two fatty acids combined) used most commonly in the production of candle wax and bars of soap. Since it was first discovered in 1811, stearic acid has been used in a variety of industrial purposes, such as: skin care products, make-up and cosmetics, shaving lotions and even in the production of multivitamins. Stearin is also commonly used in the production of paraffin wax candles as a component to help solidify the wax and allow it to stand up right without the need for a jar or other container.

Can you use stearin in candles?
If you are making your own candles, and you wish to use stearin to help your candles hold tight , make sure to buy stearin flakes rather than blocks. This allows an ease of production, as you will not have to melt down a huge chunk of stearin (or worse have to cut it down to size) in order to add it into your wax mixture.
