Description

Polyglyceryl-6 Citrullus Lanatus Seedate is a compound derived from the esterification of polyglycerin-6 with the fatty acids obtained from the seeds of the watermelon (Citrullus lanatus). This ingredient combines the hydrating and emulsifying properties of polyglycerin-6 with the nutrient-rich profile of watermelon seed oil, making it beneficial for use in various cosmetic and personal care products.

Chemical Composition and Structure

Polyglyceryl-6 Citrullus Lanatus Seedate consists of:

Polyglycerin-6: A polymer of glycerin with six glycerol units, known for its excellent moisturizing and emulsifying properties.
Watermelon Seed Oil Fatty Acids: Predominantly linoleic acid (omega-6) and oleic acid (omega-9), along with other minor fatty acids that provide nutritional and protective benefits to the skin and hair.

Physical Properties

Polyglyceryl-6 Citrullus Lanatus Seedate is typically a viscous liquid or semi-solid with a mild, neutral aroma. It is both water-dispersible and oil-soluble, making it a versatile ingredient in emulsions and formulations.

Production Process

Extraction of Watermelon Seed Oil: Seeds are collected from mature watermelons, cleaned, dried, and cold-pressed or solvent-extracted to obtain the oil.
Esterification: The fatty acids from watermelon seed oil are reacted with polyglycerin-6 under controlled conditions to form the ester compound.
Purification: The resulting product is purified to remove any unreacted materials or impurities.
Quality Control: Rigorous quality tests are conducted to evaluate the purity, stability, and composition of the final product, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, serums, and emulsions for its emulsifying, moisturizing, and nourishing properties.
Skin Care: Ideal for formulations aimed at hydrating, protecting, and revitalizing the skin due to its combined benefits of polyglycerin-6 and watermelon seed oil.
Hair Care: Incorporated into shampoos, conditioners, and treatments for its ability to nourish and strengthen hair while improving product texture and spreadability.
Personal Care Products: Used in body washes, soaps, and other personal care items for its emulsifying and hydrating effects.

Environmental and Safety Considerations

Polyglyceryl-6 Citrullus Lanatus Seedate is generally considered safe for use in cosmetic and personal care products. It is non-toxic and non-irritating to the skin. Sustainable farming practices for watermelon cultivation are important to ensure the continued availability of watermelon seeds and to protect the biodiversity of the regions where they are grown.

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.

Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.
