Aureobasidium Pullulans/Olive Oil Ferment Filtrate is a cosmetic ingredient derived from the fermentation of olive oil by the yeast Aureobasidium pullulans. This filtrate is known for its potential benefits in skin care, including its ability to enhance skin hydration and provide a range of bioactive compounds.
Chemical Composition and Structure
Components: The filtrate contains metabolites and byproducts of the fermentation process, including polysaccharides, enzymes, and other bioactive compounds.
Chemical Formula: The exact composition varies depending on the fermentation conditions, but it generally includes polysaccharides such as pullulan and various fatty acids.
Structure: The structure of the filtrate is complex, including a mix of polysaccharides and other fermentation-derived compounds.
Physical Properties
Appearance: Typically a clear to slightly opaque liquid.
Odor: Mild, often with a slight fermentation or olive oil note.
Solubility: Soluble in water and some organic solvents, making it versatile for different cosmetic formulations.
Production Process
Fermentation:
Olive oil is subjected to fermentation by Aureobasidium pullulans in controlled conditions.
The yeast breaks down the olive oil, producing a range of bioactive compounds, including polysaccharides and organic acids.
Filtration and Purification:
The fermentation mixture is filtered to remove solid yeast cells and other impurities.
The resulting filtrate is purified to concentrate the beneficial components and remove unwanted byproducts.
Standardization:
The filtrate is standardized to ensure consistent quality and effectiveness in cosmetic applications.
Applications
Cosmetics:
Hydration: Enhances skin moisture retention and improves skin texture.
Soothing: Provides soothing benefits and can reduce irritation.
Anti-Aging: Contains bioactive compounds that may help reduce the appearance of fine lines and wrinkles.
Personal Care Products:
Skin Care: Used in moisturizers, serums, and masks for its hydrating and soothing properties.
Hair Care: Included in conditioners and treatments to nourish and strengthen hair.
Food Applications
Not typically used in food applications. Primarily intended for cosmetic and personal care use.
Environmental and Safety Considerations
Biodegradability: Generally biodegradable and has a low environmental impact when properly disposed of.
Safety Profile: Generally regarded as safe for topical use. Individuals with allergies or sensitive skin should use with caution to avoid potential reactions.
Regulations: Compliant with cosmetic regulations, ensuring it meets safety and efficacy standards. It is important to ensure the filtrate is sustainably sourced and free from contaminants.
INCI Functions:
Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
Skin protectant. It creates a protective barrier on the skin to defend it from harmful substances, irritants, allergens, pathogens that can cause various inflammatory conditions. These products can also improve the natural skin barrier and in most cases more than one is needed to achieve an effective result.
