Last week, in the laboratory of Yeser Chemicals’ UAE branch, our chemist team made a great demo of a Luxurious Pearlescent Handwash Liquid formula. We also posted a detailed video on YouTube demonstrating the detailed process.
In the video, our chemist Grace explained all the ingredients used and the procedures meticulously to make this Luxurious Pearlescent Handwash Liquid with Moisturizing properties.

Procedures
Creating a luxurious handwash with a pearlescent effect involves careful preparation and precise handling of ingredients. Below is a step-by-step guide to help you achieve a lustrous handwash formulation.
Phase A: Surfactant Mixture Preparation
- Prepare the Beaker:
- Take a clean beaker suitable for heating.
- Add Surfactants:
- Add Sodium Lauryl Ether Sulfate (SLES) 70% to the beaker.
- Follow with the addition of Cocamide DEA (CDEA).
- Next, add Cocamidopropyl Betaine (CAB-35).
- Then, add Cocamide MEA (CMEA).
- Finally, add Ethylene Glycol Distearate (EGDS).
- Heat the Mixture:
- Place the beaker in a water bath set to 75°C.
- Continuously stir the mixture to ensure all surfactants melt and blend uniformly.
- Cool the Mixture:
- Once the surfactants have melted and formed a homogeneous mixture, remove the beaker from the water bath.
- Allow the mixture to cool slightly before proceeding to the next phase.
Phase B: Aqueous Solution Preparation
- Prepare the Aqueous Phase:
- Take another clean beaker and add deionized water.
- Add EDTA-2Na (Ethylene Diamine Tetraacetic Disodium) to the water.
- Add Glycerine to the solution for its moisturizing effect.
- Mix Thoroughly:
- Mix the aqueous solution well to ensure all components are fully dissolved.
Combining Phase
- Homogenize the Mixture:
- Combine the cooled surfactant mixture (Phase A) with the aqueous solution (Phase B).
- Use an overhead mixer to ensure thorough mixing and homogenization.
pH Adjustment
Measure the pH of the formulation. If the pH is not within the desired range of 5.0-6.0, adjust it by adding small amounts of citric acid.
Final Additions:
- After pH adjustment, add DMDMH (Dimethylol Dimethyl Hydantoin) preservative to the mixture.
- Add Sodium Chloride (NaCl) to achieve the desired thickness. Mix carefully to avoid over-thickening.
Final Touches
- Divide the Formulation:
- Divide the formulation into three equal parts.
- Add Fragrance and Color:
- Add different fragrances and colors to each part to create variety.
- Mix each part thoroughly to ensure uniform distribution of fragrance and color.
- Bottling:
- Transfer each colored and fragranced formulation into handwash bottles.
Observation
You will notice a lustrous texture in the handwash, thanks to the inclusion of EGDS. This pearlescent effect enhances the visual appeal, making the handwash look luxurious and attractive.
Ethylene Glycol Distearate: the spotlight ingredient
What is EGDS?
Ethylene Glycol Distearate, or EGDS for short, is the crucial ingredient in pearlescent-looking personal care products and cosmetics. EGDS dissolves and emulsifies upon heating(65℃~ 75℃) in the surfactant complex and precipitates out lens-like crystals during cooling, thus producing a pearlescent luster. It plays a 3-in-1 role in the formula, i.e., Surfactant, Opacifier, and Pearlizing agent.
Yeser® EGDS is gentle on the skin with low irritation. It features superior opacifying performance and a bright white appearance, making the final product more substantial and demonstrating a soft, velvety feel. It also can easily dissolve in water and is highly compatible with many other surfactants.
Role of EGDS in formulations
Pearlescent Agent:
- Function: EGDS is primarily used to impart a pearlescent or shimmering appearance to liquid formulations.
- Benefit: This visual appeal enhances the attractiveness of the product, making it more appealing to consumers. The pearlescent effect can give the product a luxurious and high-quality look.
Thickening Agent:
- Function: EGDS can act as a thickening agent, helping to increase the viscosity of the formulation.
- Benefit: Improved viscosity can enhance the user experience by providing a richer and more luxurious feel during application. It also ensures that the product dispenses properly from the container and spreads evenly on the skin.
Emollient:
- Function: As an emollient, EGDS helps to soften and smooth the skin.
- Benefit: This can improve the skin’s texture and feel, leaving it feeling moisturized and conditioned after use. It’s particularly beneficial in handwash formulations where repeated washing can lead to dry skin.
Stabilizing Agent:
- Function: EGDS can help stabilize emulsions, ensuring that the formulation remains homogenous and stable over time.
- Benefit: Stability is crucial for maintaining the efficacy and appearance of the product throughout its shelf life. It prevents separation and ensures consistent performance with each use.
EGDS’ Versatility in Formulations:
EGDS can be used in a variety of personal care products beyond handwashes, including shampoos, shower gels, and creams, making it a versatile ingredient for formulators.
The General Safety and Regulatory Status
Ethylene Glycol Distearate (EGDS) is generally considered safe for use in cosmetic and detergent formulations. It is non-toxic and non-irritating at typical use concentrations.
Although the skin sensitivity is rare with the use of EGDS but the patch testing is a must to be done in our laboratory to avoid some mild allergic reactions.
EGDS is permitted for use in cosmetic products by the U.S. Food and Drug Administration (FDA). It is listed in the FDA’s Voluntary Cosmetic Registration Program (VCRP). In the European Union, EGDS is approved for use in cosmetic and personal care products under the Cosmetics Regulation (EC) No 1223/2009. It is also listed in the CosIng database, which provides information on cosmetic substances and ingredients.
An Optimum Usage or Dosage of EDGS
- EGDS should be melted and incorporated into the formulation at a temperature above its melting point (65°C to 75°C) to ensure proper dispersion.
- EGDS is typically added to the oil phase or the surfactant phase of an emulsion. It can also be added to the aqueous phase if pre-dispersed.
- After addition, the formulation should be cooled with continuous stirring to ensure uniform distribution and to achieve the desired pearlescent effect.
Common Dosing Amounts
EGDS is typically used at concentrations ranging from 0.5% to 5% in personal care products and cosmetics depending on the desired effect (e.g., pearlescence, thickening).
