| Catalog Number | CI-SC-0254 |
| Product Name | Polyglyceryl-6 Laurate |
| CAS | 51033-38-6 |
| Description | Polyglyceryl-6 Laurate is a type of emulsifier that is commonly used in many personal care and cosmetic products such as creams, lotions, sunscreens, and hair care products. It is made from a mixture of glycerin and lauric acid, and has the ability to create stable emulsions by reducing the surface tension between two immiscible liquids. This means that polyglyceryl-6 laurate helps to combine water-based and oil-based ingredients in a product to create a smooth and uniform texture. Polyglyceryl-6 Laurate is often preferred over other types of emulsifiers due to its mildness and gentle nature. Additionally, it is considered to be a safer and more sustainable alternative compared to traditional emulsifiers such as sodium lauryl sulfate (SLS) which can irritate the skin and harm the environment. |
| Appearance | clear, colorless, and odorless liquid |
| Application | 1. Polyglyceryl-6 Laurate is used as an emulsifier and a surfactant in personal care and cosmetic products. 2. It helps to stabilize oil-water mixtures in lotions, creams, and other cosmetic formulations. 3. It can also be used in hair care products as a conditioning agent. 4. Polyglyceryl-6 Laurate has a natural origin and is considered safe for use in personal care products. |
| Features And Benefits | 1. Improves skin hydration 2. Enhances skin barrier function 3. Offers emulsifying properties 4. Increases viscosity of formulations 5. Reduces the irritation potential of other surfactants. |

There were 22 relatively simple oil-in-water emulsions that were made by a time/energy-saving emulsification. A natural blend of emulsifiers (Lauryl Glucoside/Myristyl Glucoside/Polyglyceryl-6 Laurate) and two emollients (INCI names both C15-19 Alkanes) are used. Furthermore, response surface methodology (RSM) optimal experimental design studies showed that the tested formulation factors (emulsifier concentration and emollient concentration and type) individually and interactively have a significant impact on the physicochemical properties, especially the rheological properties.
Preparation of emulsion samples
· All emulsions, both in type and concentration of emollient and in concentration of emulsifier, were cold emulsified at room temperature.
· Nonionic O/W emulsifier (2% or 3% w/w lauryl glucoside/myristyl glucoside/polyglyceryl-6 laurate mixture) was added to the aqueous phase, and then homogenised at 6000 rpm for 40 seconds.
· The oil phase (10%, 20%, or 30% w/w of single emollient (light liquid paraffin, Emogreen L15, Emogreen L19) was added slowly to the aqueous phase and homogenized at 4400 rpm.
· The resulting emulsion was further homogenized for 5 minutes at 8000 rpm. In the final minute of homogenization, 1% w/w preservative was added. The emulsion was then transferred to a laboratory stirrer equipped with a propeller mixing tool, where xanthan gum dispersed in glycerin was incorporated at 650 rpm for 6 minutes.
What is Polyglyceryl-6 Laurate, and what is its primary function in cosmetic formulations?
Polyglyceryl-6 Laurate is an emulsifier used in skin care and cosmetic formulations. Its primary function is to help mix oil- and water-based ingredients, ensuring they stay blended in the formula. This results in products with a smooth, uniform texture, preventing the separation of oil and water phases.
How is Polyglyceryl-6 Laurate created, and what are its sources?
Polyglyceryl-6 Laurate is created through the esterification of polyglycerol-6 and lauric acid. Lauric acid is a fatty acid commonly found in coconut oil and other natural fats. The process results in a compound that is both plant-derived and synthetic.
Is Polyglyceryl-6 Laurate safe for use in cosmetics?
Yes, the Cosmetic Ingredient Review Expert Panel has found polyglyceryl-6 laurate to be safe for use in cosmetics, provided it is used in accordance with current practices for polyglyceryl fatty acid esters.
Can Polyglyceryl-6 Laurate be used alone, or is it typically combined with other ingredients?
Polyglyceryl-6 Laurate can be used alone, typically at usage levels ranging from 1-5%. However, it is often used in blends with other emulsifiers or to help solubilize specific antioxidants, such as resveratrol and glutathione.
Why is the use of emulsifiers like Polyglyceryl-6 Laurate important in skin care products?
Emulsifiers like Polyglyceryl-6 Laurate are crucial in skin care products because they create a stable mixture of oil and water-based ingredients. Without emulsifiers, products would have irregular textures and could separate, leading to an inconsistent and less effective product experience.
