Pearlescent agent, also called pearlescent flakes. It can produce obvious pearlescent effect when used in the preparation of shampoo, bath gel, lotion and high-end liquid detergent.
The main ingredients are stearic acid ethylene glycol diester and stearic acid ethylene glycol monoester. They are introduced as follows:
 |
Stearic acid ethylene glycol diester, ethylene glycol distearate. English name: Ethylene Glycol Distearate (Glycol Distearate). Abbreviation: EGDS. CAS NO.: 627-83-8. Trade name: Pearlescent agent, pearlescent sheet, pearlescent sheet diester. Structural formula: CH3(CH2)16COOCH2 CH2OOC(CH2)16 CH3. Molecular weight: 594.97. Stearic acid ethylene glycol monoester, ethylene glycol monostearate. English name: Glycol Mono Stearate (Glycol Stearate). Abbreviation: EGMS. CAS NO.: 111-60-4. Trade name: Pearlescent agent, pearlescent sheet, pearlescent sheet monoester. Structural formula: CH3(CH2)16COOCH2 CH2OH Molecular weight: 328.52 |
Benifit and Application:
Ethylene glycol stearate is dissolved or emulsified after heating in a surfactant complex, and lens-shaped crystals will precipitate during the cooling process, thus producing a pearlescent luster. When used in liquid detergent products, it can produce a significant pearlescent effect, increase the viscosity of the product, and also has the effects of moisturizing the skin, nourishing hair and antistatic. It has good compatibility with other types of surfactants and can reflect its stable pearlescent effect and thickening and conditioning function. It is non-irritating to the skin and does not damage the hair. In contrast, the pearlescent effect produced by ethylene glycol distearate is stronger, and the pearlescent effect produced by ethylene glycol monostearate is more delicate.

Used in shampoo, bath gel, lotion and high-end liquid detergent. It can also be used as a pearlescent dispersant, solubilizer, lubricant, metal processing detergent and fiber processing in pharmaceutical production. When the product is cold-mixed, the pearlescent flakes need to be prepared into pearlescent slurry in advance. |
Experiment:
Abstract: It mainly introduces several common preparation methods of pearlescent slurry and their wide applications. Pearlescent agents are generally used by hot mixing. Another method is to use pearlescent agents and other ingredients to form pearlescent slurry. It is widely used in various pearlescent detergents.

Introduction: This experiment is mainly to study and verify the hot mixing method for preparing pearlescent slurry and its application. The pearlescent agent involved in this experiment is prepared by uniformly distributing ethylene glycol monostearate in an emulsion. Ethylene glycol monostearate is a white solid, and industrial products are usually made into flakes,called pearlescent flakes. For ease of use, some manufacturers make it into pearlescent slurry for sale.
Preparation process: Pearlescent agents are generally used by hot mixing. That is, the pearlescent agent is first melted, then added to the liquid product that has been preheated to about 75°C, and then slowly cooled until the pearlescent agent flakes are precipitated to produce pearlescent. The pearlescent effect produced by this method is not easy to control, and the operation is also more troublesome. It causes inconvenience when using pearlescent agents. Pearlescent slurry compounded with pearlescent agent and other ingredients is easy to use, stable in performance, and has good pearlescent effect, so it is very popular.

Ethylene glycol stearate is a non-ionic surfactant. It is the most widely used pearlescent agent with the best optical effect and performance. Under normal conditions, it is a white waxy or flaky body with a melting point of about 60°C. It is insoluble in water at room temperature. It is used as an oil phase component and the principle of phase inversion emulsification method is applied. Surfactants and pearlescent agents are used as raw materials, and mother fatty alcohol is used as a pearlescent enhancer. Emulsification is carried out near the phase inversion temperature of the pearlescent agent. At this temperature, the oily components are dispersed and dissolved by other surfactants. The system changes from W/O type to 0/W type, and a very stable emulsion product can be obtained. |

The specific process of this method is to mix a certain amount of pearlescent slurry with a compatible emulsion to make it dispersed evenly, and then a pearlescent product is obtained. The aqueous solution of AES, AE09, and IX-10 is heated and emulsified with pearlescent flakes and alcohol glue (cleaner 6501) under certain conditions, and the pearlescent slurry can be obtained after cooling.
