Description

Lactobacillus/Brassica Oleracea Acephala Leaf Ferment Filtrate is a fermented filtrate that combines the benefits of the probiotic Lactobacillus with those of kale leaves (Brassica oleracea var. acephala). This fermented extract is known for its skin-supporting properties and potential benefits in skincare.

Chemical Composition and Structure

The filtrate contains:

Probiotics: Derived from Lactobacillus, which supports skin barrier function and promotes a healthy skin environment.
Fermentation Metabolites: Compounds from the fermentation of kale leaves, including vitamins, minerals, and antioxidants.
Antioxidants: Substances that help protect the skin from oxidative stress and improve skin health.
Organic Acids: Products of fermentation that may contribute to skin pH regulation and hydration.
The chemical structure of the filtrate includes a mix of fermentation metabolites and probiotic compounds.

Physical Properties

Appearance: Clear to slightly cloudy liquid, light yellow in color.
Odor: Light, characteristic of fermentation, with a fermented and slightly acidic scent.
Solubility: Soluble in water; can be easily incorporated into aqueous formulations.
Texture: Liquid and lightweight.

Production Process

Preparation: Kale leaves are harvested and prepared for fermentation.
Fermentation: The leaves are fermented with Lactobacillus for a specific period, during which beneficial metabolites are produced.
Filtration: The fermented liquid is filtered to remove solid particles, resulting in a clear filtrate.
Packaging: The filtrate is packaged in airtight containers to maintain quality and freshness.

Applications

Cosmetic: Used in skincare products such as serums, toners, and masks for its hydrating, nourishing, and antioxidant properties. Helps improve skin texture and maintain a balanced skin environment.
Pharmaceutical: May be included in dietary supplements for its skin-supporting and immune system benefits.
Food: Not typically used in food products but may have applications in supplements for skin health.

Environmental and Safety Considerations

Biodegradability: The filtrate is biodegradable and environmentally friendly.
Toxicity: Generally regarded as safe for topical use. However, it should be used according to established guidelines to avoid potential allergic reactions or sensitivities. People with allergies or sensitive skin should exercise caution. It is important to ensure the filtrate is sustainably sourced and free from contaminants.
Disposal: Should be disposed of according to local environmental regulations. Proper disposal methods should be followed to prevent environmental impact.

INCI Functions:


Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.

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.
