Description

Lactobacillus/Salix Alba Bark Extract Ferment Filtrate is a filtrate derived from the fermentation of Salix alba bark extract with Lactobacillus bacteria. This product is used in skincare for its potential benefits, including soothing, anti-inflammatory, and antimicrobial properties.

Chemical Composition and Structure

Active Compounds: Contains a mix of lactic acid, salicylic acid, salicin, and other fermentation metabolites. Lactic acid is known for its exfoliating and hydrating properties, while salicylic acid has anti-inflammatory effects.
Salicin: The primary active component from willow bark that converts into salicylic acid.

Physical Properties

Appearance: Clear to slightly yellow liquid.
Odor: Mild, with a subtle vegetal and fermented scent.
Solubility: Soluble in water-based formulations.
Texture: Lightweight and easily absorbed by the skin.

Production Process

Fermentation: Salix alba bark extract is combined with Lactobacillus bacteria and fermented.
Filtration: The mixture is filtered to remove solids, resulting in a clear filtrate.
Concentration (if needed): The filtrate may be concentrated to enhance its efficacy.
Packaging: The final product is packaged under sterile conditions to maintain quality.

Applications

Cosmetic: Used in skincare products for its exfoliating, anti-inflammatory, and antimicrobial properties. Commonly found in serums, toners, and treatments for sensitive or acne-prone skin.
Pharmaceutical: May be used in topical treatments for its soothing and antimicrobial effects.
Food: Not typically used in food products.

Environmental and Safety Considerations

Biodegradability: Designed to be environmentally friendly and biodegradable.
Toxicity: Generally regarded as safe for topical use. Should be used according to established guidelines to avoid potential allergic reactions or skin irritations. People with sensitivities to salicylates or fermented products should exercise caution. Ensure the filtrate is sustainably sourced and free from harmful contaminants.
Disposal: Dispose of according to local environmental regulations to minimize 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.

Skin conditioning agent - Humectant. Humectants are hygroscopic substances 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 the 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: corneum, the most superficial, lucidum, granulosum, spinosum and basale. Humectants have the ability to retain in the stratum corneum the water they attract from the air and have the function of moisturising the skin. It is better to use them before emollients that are oil-based.
