Octisalate (2-Ethylhexyl salicylate) is a cosmetic ingredient used primarily as a UV filter and stabilizer in sunscreens and other personal care products. It helps to enhance the efficacy of sunscreen formulations by stabilizing other UV filters and protecting the skin from harmful UV radiation.

Chemical Composition and Structure:

Components:
Octisalate (also known as Octyl Salicylate): A salicylic acid derivative that is used to stabilize and enhance the effectiveness of sunscreens.

Structure:
Octisalate: Chemically known as Octyl Salicylate, it is an ester formed from salicylic acid and octyl alcohol. Its chemical formula is C15H22O3.

Physical Properties:

Appearance: Colorless to pale yellow liquid.
Odor: Typically odorless or has a very mild scent.
Solubility: Soluble in oil and some organic solvents, but not in water.
pH: Does not significantly affect the pH of cosmetic formulations.

Production Process:

Synthesis: Octisalate is synthesized through the esterification of salicylic acid with octyl alcohol. This chemical reaction creates a stable compound used in various cosmetic applications.
Formulation: Once synthesized, Octisalate is blended into cosmetic formulations, especially sunscreens, where it helps stabilize other UV filters and enhance overall sun protection.

Applications:

Sunscreens: Used as a UV filter to provide additional protection against UVB radiation. It helps to stabilize other UV filters and prevent the breakdown of sunscreen formulations.
Moisturizers and Lotions: Added to enhance the UV protection capabilities of the product and improve overall product stability.
Cosmetic Products: Included in various beauty and skincare products to ensure that UV filters maintain their effectiveness and stability.

Environmental and Safety Considerations:

Environmental Impact: Generally considered to have a low environmental impact. It is biodegradable, but as with all chemicals, should be used in moderation.
Safety: Octisalate is considered safe for use in cosmetics and personal care products when used as directed. However, individuals with sensitive skin or allergies should exercise caution.

Cosmetic safety

Restricted cosmetic ingredient as VI/20 a Relevant Item in the Annexes of the European Cosmetics Regulation 1223/2009. Substance or ingredient reported: 2-Ethylhexyl salicylate / Octisalate). Maximum concentration in ready for use preparation 5%.

INCI:


Light stabilizer. It prevents light from degrading light-sensitive components and slows down degradation reactions that have already begun. The mechanism is, in a way, similar to antioxidants and the effectiveness depends on the.complexity of the formulation and the density of the 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.
