ISOSTEARETH-11 CARBOXYLIC ACID.

Insufficient Data / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

ISOSTEARETH-11 CARBOXYLIC ACID functions primarily as a cleansing and emulsifying surfactant, adept at reducing surface tension to facilitate the mixing of oil and water in cosmetic formulations. Its amphiphilic nature contributes to its versatility across various skincare and personal care products.

Summary

Cleansing Emulsifying Surfactant

Science

Mechanism of Action

This ingredient acts as a surfactant by significantly lowering the surface tension of liquids, which enables immiscible substances like oil and water to combine effectively. Chemically, as a carboxylic acid, it forms electrostatic interactions and hydrogen bonds, enhancing its solubility in water. Its action is comparable to its sodium salt counterpart, Sodium Isosteareth-11 Carboxylate.

Stability

Carboxylic acids generally exhibit good water solubility. While specific pH data for ISOSTEARETH-11 CARBOXYLIC ACID is not available, related compounds like Laureth-11 Carboxylic Acid are noted for their stability across a broad pH spectrum, performing well in acidic, neutral, and dilute alkaline conditions. Its surfactant properties indicate an ability to interact with both aqueous and oil phases.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated ISOSTEARETH-11 CARBOXYLIC ACID. Although CIR reviews broader ingredient groups, detailed safety data for this particular compound, and even its related sodium salt, remains unavailable. Over-the-counter cosmetic ingredients are regulated by the FDA as cosmetics, which typically defers safety assessments to industry bodies like CIR.

Verdict

Insufficient Data

Due to the absence of specific safety assessments by regulatory bodies and a lack of clinical studies on its efficacy and skin compatibility, there is insufficient data to confidently assess ISOSTEARETH-11 CARBOXYLIC ACID for precision skincare formulations.
