Science
Mechanism of Action
This multifunctional ingredient acts by effectively stabilizing emulsions, ensuring uniform distribution of oil and water components within a formula. Its polyglycerin-3 component provides hydrating qualities, while capric and caprylic acids contribute to a light skin feel and rapid absorption. Succinic acid offers buffering and chelating capabilities. As an emollient, it reinforces the skin's natural barrier by providing exogenous lipids, thereby enhancing hydration and preventing transepidermal water loss. It also functions as a surfactant, reducing surface tension for effective cleansing, and can serve as a solvent. Additionally, it has been noted to improve the penetration of active ingredients and exhibits mild antimicrobial and deodorizing characteristics.

Key findings
- 01 Research on Polyglyceryl-3 Caprate, a core component, indicates that at concentrations between 1.0% and 3.0% in hair and skin cleansing products, it significantly enhances viscosity and delivers a softer skin feel, coupled with mild antimicrobial and deodorizing benefits.
- 02 Further studies on Polyglyceryl-3 Caprate demonstrated an improvement in skin barrier function, evidenced by reduced Trans Epidermal Water Loss (TEWL). It also provided benefits in skin feel enhancement, smoothing, thickening, foam boosting, and mitigating properties within formulations.

Stability
This ingredient exhibits solubility in oils and partial solubility in water, making it well-suited for stable oil-in-water emulsions. Precise pH control is necessary during its manufacturing process. Polyglyceryl-3 Caprate, a related compound, is noted to have a pH of 7.0 and contributes to increased viscosity in formulations like shampoos and shower gels.
Safety
Safety Profile
The CIR Expert Panel has concluded that polyglyceryl fatty acid esters, including Polyglyceryl-3 Caprate, are safe for cosmetic use under current practices and concentrations when formulated to be non-irritating. Polyglyceryl-3 Caprate/Caprylate/Succinate itself is generally well-tolerated, presenting a low risk for irritation or allergic reactions.
