What is Glyceryl Tristearate?

Glyceryl tristearate is a type of stearic acid, and also glyceryl tristearate is a nonionic surfactant.It has both hydrophilic as well as lipophilic genetics, and also has numerous functions such as wetting, emulsifying, and also frothing. Glyceryl tristearate is an emulsifier and also additive for food; it is taken advantage of as an emulsifier in cosmetics as well as pharmaceutical lotions to make the lotion delicate as well as also smooth; it is made use of as an emulsifier for industrial silk oils and also a lubricating substance for fabrics; in plastic films Made use of as a dripping agent along with anti-fogging agent;as a lube and antistatic representative in plastic processing, and as a defoamer, dispersant, thickener, moistening agent, etc in other facets. It is generally used as a safe stabilizer for polyvinyl chloride, a lubricant for cosmetics, a styrene resin, a launch agent for bakelite items, a flatting representative for paint, as well as a conditioner and release representative for rubber compounds in the rubber industry. It is widely utilized. With the advancement of markets such as plastics, coverings as well as petrochemicals, the need for glyceryl tristearate in the domestic market is enhancing year by year.

Application of Glyceryl Tristearate

Preparation of Glyceryl Tristearate
S1: Take tristearin, stir while feeding, keep the temperature at 100°C, add catalyst A, antioxidant and water after the tristearin is completely melted, at a temperature of 135°C and a pressure of 0.7MPa Carry out hydrolysis reaction under the condition of condition, hydrolyzate stands still 45min, oil and water are separated, and oil phase pressure filtration reclaims catalyst and promptly obtains stearic acid;

Wherein, in terms of mass ratio, in catalyst A, zinc oxide: Al2O3-MgO is 1: 6, and its consumption is 4% of the quality of glyceryl tristearate, and Al2O3-MgO is prepared by precipitation method, and in molar ratio, Al2O3:MgO is 2.5:1;

In terms of mass ratio, in antioxidants, antioxidant 1076: antioxidant DLTDP: antioxidant T501 is 0.12: 0.38: 1, and its consumption is 0.5% of tristearin quality;

By mass ratio, glyceryl tristearate: water is 1: 0.45;

S2: Add the stearic acid in S1 into the zinc stearate reaction kettle, keep the temperature at 110°C, add zinc oxide with 9% mass of tristearin while stirring, after feeding, the temperature of the material rises to 120°C , add catalyst B with 3% glyceryl tristearate mass, and stir for 30 minutes;

Wherein, catalyst B is the mixture of hydrogen peroxide and zinc peroxide, by mass ratio, hydrogen peroxide: zinc peroxide is 4: 1;

S3: Add zinc oxide with 3.8% tristearin mass and catalyst B with 2% tristearin mass, react at a temperature of 130°C, stop stirring, and the foam of the material drops to the equilibrium point , add catalyst B with 0.5% tristearin mass, and react at a temperature of 150° C. for 20 minutes;

S4: Add sodium hydroxide of 0.25% by mass of glyceryl tristearate while stirring, and react at constant temperature for 30 minutes;

S5: Turn on the vacuum pump, adjust the vacuum degree to -0.08MPa, dehydrate, and react stably for 60 minutes under constant temperature and constant pressure conditions, the reaction is terminated, sampling and testing, spraying powder after passing the test, packaging and storage, to obtain zinc stearate, the yield is 94.87%.

Antistatic agent and its preparation
Formula: 30kg of glyceryl tristearate, 10kg of pentaerythritol monostearate.

Preparation method: put pentaerythritol stearate and glyceryl tristearate into the reaction kettle, fill with nitrogen to control the negative pressure at 0.01MPa, raise the temperature to 120°C, react with stirring for 30min, then cool down to 110°C to obtain anti- Static agent.

Preparation of Glyceryl Tristearate

1) Treat the hydrogenated oil: suck the hydrogenated oil into the decolorization pot with a vacuum pump, start stirring, heat up the steam to 90°C, vacuum dehydrate for about 15 minutes, suck the prepared activated clay into the decolorization pot, stir and raise the temperature to 100°C, Use compressed air to filter the material in the decolorization pot through a plate and frame filter press, put the decolorized and filtered hydrogenated oil into the middle tank, and transport it to the hydrogenated oil metering tank;

2) Pre-mixing: Use a gear pump to pump 200kg of hydrogenated oil in the hydrogenated oil metering tank and 40kg of glycerin in the glycerin pool into the mixing tank through a mass flow meter, start stirring and pre-mixing, wait until the liquid level reaches the discharge position, start mixing Kettle discharge pump, put the mixed material into the esterification kettle, and the discharge pump controls the speed through the liquid level automatic control pump;

3) Transesterification reaction: In a vacuum state, put 12 kg of sodium stearate into the esterification kettle through a flow meter with a gear pump, and use heat conduction oil to heat up the temperature. Stir continuously during heating, and raise the temperature to 220 ° C. During the reaction, Fill with nitrogen, wait until the liquid level of the esterification tank reaches the discharge position, start the discharge pump of the mixing tank, the discharge pump automatically controls the speed of the pump through the liquid level, put the material in the esterification tank into the esterification tank, and continue heating and stirring Heating reaction, the temperature is raised to 240° C., nitrogen is filled during the reaction, and the nitrogen pressure is 0.08 Mpa. When the reaction becomes a transparent solution, the transesterification reaction is completed.

4) When the liquid level of the esterification kettle reaches the discharge position, start the discharge pump of the esterification kettle. The discharge pump automatically controls the pump speed through the liquid level, and the reacted materials are quenched through the cooler, and then enter the Finished high slot;

5) Continue to cool the material to below 100°C in the high-level tank of the finished product, and then carry out pouring or cold roller scraping molding, and finally obtain glyceryl tristearate.

Features of Glyceryl Tristearate

Glyceryl tristearate has excellent low temperature performance and good oxidation stability. It has high solubility, low odor, low foam, and has good compatibility with various complex formulations such as ester oils, silicone resin emulsifiers and color cosmetics. Its sensory experience, comparable to that of isopropyl myristate, gives a refreshing sensation. Easy spread and fast penetration make it suitable as emollient, emulsifier and dispersant.
