Description

Rosa Chinensis Callus Lysate is a bioactive ingredient derived from the lysed cells of Rosa chinensis, commonly known as the China Rose. This extract is used in the cosmetic and skincare industries for its powerful rejuvenating, moisturizing, and anti-aging properties. It is valued for its ability to enhance skin hydration, improve skin elasticity, and support overall skin regeneration.

Chemical Composition and Structure:
Rosa Chinensis Callus Lysate contains a range of bioactive compounds, including:

Growth Factors: These include various peptides and proteins that stimulate cell regeneration and repair processes in the skin.
Flavonoids: Such as quercetin and kaempferol, which provide antioxidant protection and help reduce oxidative stress.
Phenolic Compounds: Including phenolic acids and tannins, which contribute to the extract’s anti-inflammatory and astringent properties.
Polysaccharides: These help retain moisture and enhance the skin’s hydration levels.

These components feature complex molecular structures, including peptide chains for growth factors, aromatic rings for flavonoids, and polysaccharide chains for moisturizing effects.

Physical Properties:

Appearance: The lysate is typically a liquid, with a color ranging from pale yellow to light brown, depending on concentration and processing method.
Odor: It has a subtle, fresh aroma characteristic of the Rosa chinensis plant.
Solubility: Soluble in water and alcohol; generally insoluble in oil.

Production Process:

Cell Culture: Rosa chinensis cells are cultured under controlled conditions to produce a callus culture rich in bioactive compounds.
Lysis: The cells are lysed (broken down) to release their internal contents, including growth factors and other beneficial compounds.
Extraction and Purification: The lysate is then extracted and purified to remove impurities and concentrate the beneficial components.
Formulation: The purified lysate is incorporated into various cosmetic and skincare products, including serums, creams, and masks.

Applications:

Cosmetics: Used in facial creams, serums, and masks for its rejuvenating, anti-aging, and moisturizing properties.
Skincare: Beneficial for enhancing skin hydration, improving skin elasticity, and supporting skin regeneration.
Haircare: May be included in hair products to promote scalp health and provide conditioning benefits.

Environmental and Safety Considerations:

Environmental Impact: The production of Rosa Chinensis Callus Lysate is generally sustainable if the cell cultures are maintained responsibly and the extraction processes are managed in an environmentally friendly manner.
Safety: This ingredient is generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals with allergies to Rosaceae family plants should be cautious.

INCI:


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.
