What Is Polyglyceryl-6 Tristearate?
Polyglyceryl-6 Tristearate, also known by its chemical name 1,2,3-Propanetriol, homopolymer, octadecanoates (1:3) (6 mol glycerol average molar ratio), is a versatile emulsifying agent commonly used in cosmetic formulations. This ingredient is derived from glycerol and stearic acid, both of which are naturally occurring substances. Glycerol, or glycerin, is a simple polyol compound, while stearic acid is a saturated fatty acid typically found in animal and plant fats.
The use of Polyglyceryl-6 Tristearate in cosmetics has a relatively recent history, emerging as a response to the growing demand for more natural and skin-friendly emulsifiers. Traditional emulsifiers often relied on synthetic chemicals that could be harsh on the skin. Polyglyceryl-6 Tristearate, on the other hand, offers a more gentle alternative, making it a popular choice for modern skincare and beauty products.
The production of Polyglyceryl-6 Tristearate involves a process called esterification, where glycerol is polymerized to form polyglycerol, which is then reacted with stearic acid. This results in a compound that can effectively stabilize mixtures of oil and water, ensuring that the ingredients in your favorite lotions, creams, and serums remain well-blended and effective.
The Benefits/Uses of Polyglyceryl-6 Tristearate
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polyglyceryl-6 Tristearate:
Emulsifying Agent
Polyglyceryl-6 Tristearate is primarily known for its role as an emulsifying agent. In simple terms, this means it helps to blend ingredients that typically don’t mix well together, like oil and water. This is crucial in many cosmetic formulations, ensuring that products like creams, lotions, and serums have a smooth, uniform texture. Without emulsifiers, these products would separate, leading to an inconsistent application and reduced effectiveness.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Potential Side Effects & Other Considerations
Polyglyceryl-6 Tristearate is generally considered to be a safe ingredient in cosmetic formulations. It is known for its emulsifying properties, which help to blend oil and water-based components in a product. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
- Skin irritation: Some individuals may experience mild irritation, especially if they have sensitive skin.
- Allergic reactions: Although rare, allergic reactions such as redness, itching, or swelling can occur.
- Contact dermatitis: In very rare cases, prolonged use may lead to contact dermatitis.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Polyglyceryl-6 Tristearate during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to Polyglyceryl-6 Tristearate are uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
In terms of comedogenicity, Polyglyceryl-6 Tristearate has a rating of 1 on a scale of 0 to 5, where 0 is totally non-comedogenic and 5 is highly comedogenic. This low rating indicates that it is unlikely to clog pores and cause acne or breakouts, making it suitable for individuals prone to blemishes.
