Description

Rosa Multiflora Leaf/Stem Extract is derived from the leaves and stems of the Rosa multiflora plant. This extract is known for its antioxidant, anti-inflammatory, and skin-conditioning properties and is used in various cosmetic and skincare products.

Composition and Chemical Structure:

Tannins: Provide astringent properties and help to tone and tighten the skin.
Flavonoids: Offer antioxidant benefits, helping to neutralize free radicals and reduce oxidative stress.
Phenolic Compounds: Contribute to anti-inflammatory effects and overall skin health.

Physical Properties:

Appearance: Usually a dark green or brown liquid, depending on the concentration and extraction process.
Odor: A mild, earthy, or herbal scent, characteristic of plant extracts.
Texture: Generally smooth and somewhat viscous, with good spreadability on the skin.

Production Process:

Harvesting: Leaves and stems of the Rosa multiflora plant are collected, typically during the plant's growth phase to ensure optimal extraction.
Extraction: The plant material is processed through methods such as solvent extraction or steam distillation to obtain the active compounds.
Purification: The extract is purified to concentrate the beneficial components and remove impurities.
Formulation: The purified extract is integrated into skincare and cosmetic products.

Applications:

Skincare Products: Included in creams, serums, and lotions for its soothing, anti-inflammatory, and antioxidant properties.
Anti-Aging Products: Used in formulations aimed at reducing visible signs of aging, such as fine lines and skin sagging.
Toners and Astringents: Applied in products designed to tighten and tone the skin.

Environmental and Safety Considerations:

Environmental Impact: Cultivation of Rosa multiflora is typically managed with sustainable practices.
Safety: Generally considered safe for topical use. It is always advisable to check for any allergic reactions or individual sensitivities.

INCI:


Antioxidant agent. Ingredient that counteracts oxidative stress and prevents cell damage. Free radicals, pathological inflammatory processes, reactive nitrogen species and reactive oxygen species are responsible for the ageing process and many diseases caused by oxidation.

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.
