Rosa Moschata Oil, also known as Musk Rose Oil, is extracted from the seeds of the Rosa moschata plant, commonly referred to as musk rose. This oil is highly regarded in the cosmetic and skincare industries for its nourishing, moisturizing, and regenerative properties. It is prized for its potential to improve skin health, reduce the appearance of scars and wrinkles, and provide overall hydration and rejuvenation.

Chemical Composition and Structure:
Rosa Moschata Oil is rich in various bioactive compounds, including:

Essential Fatty Acids: Such as linoleic acid (omega-6) and alpha-linolenic acid (omega-3), which are crucial for maintaining the skin’s barrier function and hydration.
Vitamin E: An antioxidant that helps protect the skin from oxidative stress and supports overall skin health.
Phenolic Compounds: Including ellagic acid, which offers additional antioxidant benefits and helps reduce inflammation.
Squalene: A natural emollient that helps to moisturize and protect the skin.

These components feature complex molecular structures, with long hydrocarbon chains for fatty acids, aromatic rings for phenolic compounds, and cyclic structures for squalene.

Physical Properties:

Appearance: The oil is typically a light yellow to golden liquid, with variations depending on the extraction method and purity.
Odor: It has a subtle, earthy, and slightly nutty aroma characteristic of musk rose oil.
Solubility: Soluble in other oils and lipid-based solvents; generally insoluble in water.

Production Process:

Harvesting: Seeds of Rosa moschata are collected, usually when the fruits are fully mature, to ensure the highest concentration of beneficial compounds.
Extraction: The seeds are processed to extract the oil, typically using methods such as cold pressing or solvent extraction. Cold pressing is preferred to maintain the oil's natural properties.
Purification: The oil is purified to remove impurities and concentrate beneficial components, typically through filtration and refining processes.
Formulation: The purified oil is incorporated into various cosmetic and skincare products, including moisturizers, serums, and creams.

Applications:

Cosmetics: Used in products such as facial oils, moisturizers, and serums for its hydrating, nourishing, and regenerative properties.
Skincare: Beneficial for improving skin texture, reducing the appearance of scars and wrinkles, and providing deep hydration.
Haircare: Can be added to hair products to enhance conditioning and support scalp health.

Environmental and Safety Considerations:

Environmental Impact: The production of Rosa Moschata Oil is generally sustainable if the seeds are harvested responsibly and extraction processes are managed in an environmentally friendly manner.
Safety: The oil is generally safe for topical use and is well-tolerated by most skin types. It is advisable to perform a patch test before extensive use to ensure no adverse reactions occur.

Cosmetic safety

Restricted cosmetic ingredient as III/366 a Relevant Item in the Annexes of the European Cosmetics Regulation 1223/2009.

INCI:


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.

Fragrance. It plays a very important role in the formulation of cosmetic products as it provides the possibility of enhancing, masking or adding fragrance to the final product, increasing its marketability. It is able to create a perceptible pleasant odour, masking a bad smell. The consumer always expects to find a pleasant or distinctive scent in a cosmetic product.

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.
