LAURETH-10 CARBOXYLIC ACID.

Valuable CAS 27306-90-7 / CLEANSING, SURFACTANT - CLEANSING

Laureth-10 Carboxylic Acid is a versatile anionic surfactant that effectively cleanses the skin by reducing surface tension, facilitating the removal of dirt and impurities. It also functions as an oil-in-water emulsifier, enhancing product stability and texture.

surfactant emulsifying cleansing solubilizer foam boosting

Science

Mechanism of Action

This ingredient operates primarily as a surfactant, actively lowering the surface tension between oil and water phases, which allows them to mix and aids in the emulsification of substances like dirt and sebum for effective cleansing. It also stabilizes oil-in-water (O/W) emulsions, creating a harmonious blend of immiscible ingredients, thereby improving product consistency and longevity. Furthermore, it contributes to foam generation and can modify rheological properties to achieve desired product textures. A closely related compound, Laureth-11 carboxylic acid, is noted for its ability to improve the softness of formulations and reduce the irritating potential of other surfactants, suggesting similar benefits for related 'Laureth ingredients'.

Stability

Laureth-10 is observed to maintain stability at low pH levels. Related Laureth-11 carboxylic acid demonstrates stability across a broad pH spectrum, remaining effective in acidic, neutral, and dilute alkaline environments.

Synergies

  • When used as a co-surfactant, particularly drawing parallels from Laureth-11 carboxylic acid, it may contribute to milder formulations, enhance softness, and potentially mitigate the irritating effects of other surfactants.

Conflicts

  • As a carboxylic acid, it has the potential to alter the pH balance of a formulation, which could impact the efficacy or stability of other pH-sensitive ingredients.
  • Caution is advised when combining with cationic ingredients, as strong interactions can occur between anionic carboxylate-based surfactants and cationic species, potentially affecting product stability or performance.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel deems Laureth ingredients, including Laureth-10, safe for cosmetic use when formulations are developed to be non-irritating. Improper formulation can lead to skin irritation. Manufacturers must ensure purification steps are taken to control the presence of 1,4-dioxane, a potential ethoxylation by-product. Laureth-10 Carboxylic Acid is listed in the FDA Global Substance Registration System (GSRS).
