Skin Type Suitability/Concerns: Suitable for all skin types. However, individuals with sensitive skin or those prone to allergic reactions should patch test it first.

Target Audience: Individuals seeking natural moisturizing ingredients, those with dry skin or hair, and those interested in promoting hair health.

Chemical Composition: Mainly composed of fatty acids, the most abundant of which is ricinoleic acid.

Physical Aspect: It's a pale yellow, viscous liquid with a slight odor.

Compatibility: Compatible with most oils and cosmetic ingredients. It's often mixed with other carrier oils for application to skin or hair.

Concentration: Varies depending on the product and intended use. Hair products may contain higher concentrations.

Side Effects/Adverse Reactions: Generally safe for topical use. However, it may cause allergic reactions in some individuals. Should not be ingested due to potential toxicity.

Sustainability/Ethical Considerations: Castor oil is a renewable resource, and the Ricinus communis plant can be grown in many different climates and soils. However, ethical sourcing and production practices can vary among suppliers.

Castor Oil Variants:

1. Cold-Pressed Castor Oil: This is the most common type of castor oil. The seeds are cold-pressed to extract the oil, preserving its natural benefits.

2. Jamaican Black Castor Oil: This variant is processed differently. The seeds are roasted before pressing, which leads to a darker color and a slightly different composition.

3. Hydrogenated Castor Oil: Also known as castor wax, this oil has been hydrogenated to make it harder and raise its melting point. It's often used in cosmetics for its ability to stabilize and thicken formulations.

4. PEG Castor Oils: These are variants of castor oil that have been ethoxylated, a process that makes them more water-soluble. They are often used as surfactants or emulsifiers in cosmetic products.
