Description

Ribes Nigrum Fruit Extract is derived from the blackcurrant fruit (Ribes nigrum). This extract is highly valued in cosmetics for its rich content of vitamins, antioxidants, and other bioactive compounds, which contribute to its beneficial effects on the skin.

Chemical Composition and Structure:

Ribes Nigrum Fruit Extract contains a variety of bioactive compounds, including anthocyanins, flavonoids, Vitamin C, and essential fatty acids. Anthocyanins, responsible for the dark color of the extract, provide strong antioxidant properties. The chemical structure of these compounds includes hydroxyl groups and flavonoid structures, which contribute to their biological activity and protective effects.

Physical Properties:

The extract typically appears as a dark purple or black liquid with a fruity aroma. It has a slightly viscous consistency and is soluble in water. The extract generally has a slightly acidic pH.

Production Process:

The production of Ribes Nigrum Fruit Extract involves the following steps:

Harvesting: Blackcurrant fruits are collected at maturity.
Extraction: The fruits are processed using methods such as solvent extraction or cold pressing to obtain the soluble components.
Filtration: The extract is filtered to remove solids and impurities.
Standardization: The extract may be standardized to ensure consistent quality and concentration of active ingredients.

Applications:

Ribes Nigrum Fruit Extract is used in cosmetic formulations for its antioxidant, anti-inflammatory, and skin-conditioning benefits. It can be found in:

Anti-aging creams
Facial serums
Moisturizers
Face masks
It is also used in hair care products for its conditioning properties and to provide a natural fruity fragrance.

Environmental and Safety Considerations:

The environmental impact of producing Ribes Nigrum Fruit Extract is relatively low, particularly with sustainable harvesting practices. The extract is generally considered safe for topical use and has a low risk of irritation or sensitization. As with any cosmetic ingredient, proper formulation and safety testing are important, especially for products intended for sensitive skin.

INCI Functions:


Cosmetic astringent. This ingredient exerts a direct effect on the skin by tightening dilated pores by contracting stratum corneum cells and removing superfluous oil.

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. 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.

Perfuming. Unlike fragrance, which can also contain slightly less pleasant or characteristic odours, the term perfume indicates only very pleasant fragrances. Used for perfumes and aromatic raw materials.
