Chemical Identity
Chemical Name: Avocado Oil Polyglyceryl-6 Esters
CAS Number: 90990-06-0
Molecular Formula: C₁₈H₃₆O₂
EINECS Number: 292-767-5
Synonyms: Tetraglyceryl monooleate (CAS 33940-98-6)
Source and Composition
This ingredient is derived from the fruit of Persea gratissima (avocado), a plant native to Mexico and Central America.
Avocado oil is rich in monounsaturated fatty acids, particularly oleic acid, which constitutes approximately 71% of its fatty acid profile.
The esterification with polyglycerol-6 enhances its emulsifying properties, making it suitable for various cosmetic applications.
Synthesis Process
The production of Avocado Oil Polyglyceryl-6 Esters involves the following steps:
Extraction of Avocado Oil: Cold pressing or solvent extraction methods are employed to obtain avocado oil from the fruit pulp.
Esterification Reaction: Avocado oil undergoes transesterification with polyglycerol-6 in the presence of a catalyst, forming the desired esters.
Purification: The reaction mixture is purified to remove unreacted materials and by-products, ensuring a high-quality final product.
Physical and Chemical Properties
Appearance: Clear to slightly yellow liquid
Odor: Mild, neutral
Solubility: Soluble in oils and organic solvents; limited solubility in water
HLB (Hydrophilic-Lipophilic Balance): Typically low, indicating suitability for water-in-oil emulsions
Functional Properties in Cosmetics
Avocado Oil Polyglyceryl-6 Esters serves multiple roles in cosmetic formulations:
Emulsifier: Facilitates the formation and stabilization of emulsions, particularly water-in-oil types.
Moisturizer: Enhances skin hydration by forming a barrier that reduces water loss.
Conditioner: Improves the texture and feel of skin and hair, imparting a smooth and soft sensation.
Applications in Formulations
This ingredient is utilized in a variety of cosmetic and personal care products, including:
Creams and Lotions: To improve texture and stability.
Hair Care Products: For conditioning and enhancing shine.
Sun Care Products: As part of formulations requiring emulsification.
Lip Care Products: To provide moisture and protection.
Regulatory Status and Safety
Avocado Oil Polyglyceryl-6 Esters is generally recognized as safe for use in cosmetics.
The Cosmetic Ingredient Review (CIR) has evaluated polyglyceryl fatty acid esters, including those derived from avocado oil, and concluded that they are safe for use in cosmetics under current practices.
Research and Development
Ongoing research continues to explore the properties and applications of polyglycerol fatty acid esters.
Studies have highlighted their utility as renewable, non-ionic surfactants derived from natural sources like glycerol and fatty acids.
These esters are particularly noted for their low hydrophilic-lipophilic balance (HLB), making them effective in water-in-oil emulsions.
