Description

Kluyveromyces/Saccharomyces/Olive Leaf Extract Ferment is a cosmetic ingredient obtained from the fermentation of olive leaf extract using Kluyveromyces and Saccharomyces yeasts. This ferment is valued for its potential skin benefits, providing moisturizing and nourishing properties due to the bioactive compounds produced during fermentation.

Chemical Composition and Structure

Components: The ferment contains metabolites and by-products from fermentation, including polysaccharides, proteins, and other bioactive compounds.
Chemical Formula: The exact composition can vary but includes polysaccharides, enzymes, and organic acids resulting from the fermentation process.
Structure: The ferment features a complex structure composed of a mix of polysaccharides and other metabolites.

Physical Properties

Appearance: Typically a clear or slightly opaque liquid, depending on the production process.
Odor: Mild, with hints of fermentation and olive.
Solubility: Water-soluble, making it easily incorporable into cosmetic formulations.

Production Process

Fermentation:
Olive leaf extract is fermented using Kluyveromyces and Saccharomyces yeasts under controlled conditions.
This process generates a range of bioactive compounds through the breakdown of the olive leaf extract.
Filtration and Purification:
After fermentation, the mixture is filtered to remove yeast cells and other impurities.
The filtrate is then purified to concentrate beneficial components and remove any unwanted by-products.
Standardization:
The ferment is standardized to ensure consistent quality and effectiveness in cosmetic applications.

Applications

Cosmetics:

Hydration: Helps to enhance skin hydration and maintain elasticity.
Soothing: Has soothing properties that can help reduce irritation and redness.
Anti-Aging: Contains compounds that may support skin in reducing the appearance of wrinkles and promoting a smoother, more even complexion.

Personal Care Products:

Skin Care: Used in moisturizers, serums, and masks for its nourishing and hydrating benefits.
Hair Care: May be included in shampoos and conditioners for its nourishing and strengthening properties.

Food Applications

Not commonly used in food applications and primarily focuses on cosmetic and personal care uses.

Environmental and Safety Considerations

Biodegradability: Generally biodegradable and has a low environmental impact when disposed of properly.
Safety Profile: Considered safe for topical use. However, individuals with sensitive skin or allergies should exercise caution and monitor for any reactions.
Regulations: Complies with cosmetic standards, ensuring it meets safety and efficacy requirements. It is important to ensure that the ferment is produced sustainably and free from contaminants.

INCI Functions:


Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

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.
