PEG-114 POLYLACTIC ACID.

Valuable CAS - / EMULSION STABILISING, FILM FORMING, SURFACTANT - EMULSIFYING

PEG-114 POLYLACTIC ACID is a sophisticated copolymer engineered to improve skin texture and cellular vitality. It functions as a mild exfoliant, promoting skin renewal and refining overall smoothness, while also acting as a film-forming agent to enhance moisture retention. This ingredient further contributes to the stability of emulsions and can facilitate the optimized delivery of other active compounds.

Emulsion Stabilizing Film Forming Surfactant - Emulsifying Exfoliating Cell Renewal Promoting Collagen Stimulating Moisture Retention Ingredient Delivery Enhancer

Science

Mechanism of Action

This ingredient operates through a dual mechanism, harnessing the distinct properties of its polylactic acid (PLA) and polyethylene glycol (PEG) components. The polylactic acid segment gently removes dead skin cells, stimulating cellular turnover to improve skin smoothness, texture, and tone. Specific forms, such as Poly-L-Lactic Acid (PLLA), are known to activate fibroblasts, leading to enhanced collagen production for skin filling and tightening effects, and improved dermal collagen synthesis via M2 macrophage polarization modulation in aging skin. Additionally, PLA forms a protective film to bolster moisture retention. The polyethylene glycol component primarily acts as an emulsion stabilizer, film-former, and emulsifying agent, contributing to formulation integrity. As a copolymer, PEG-PLA is also capable of enhancing the penetration and delivery of other active ingredients into the skin.

Stability

Poly(lactic acid) polymers demonstrate tunable hydrolytic stability and biodegradability. The degradation of related copolymers, such as mPEG-PDLLA, is observed to release lactic acid, which subsequently lowers the local pH. This pH reduction is implicated in fostering fibroblast proliferation and sustained collagen synthesis, suggesting a degree of pH sensitivity for its degradation. The PEG component inherently contributes to the stability of emulsions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

Polylactic Acid (PLA) is generally regarded as safe for cosmetic use due to its biocompatibility and minimal potential for irritation. Polyethylene Glycols (PEGs) and their derivatives are also considered safe for cosmetic application; previous concerns regarding use on damaged skin have been addressed. Manufacturers of PEG compounds are encouraged to maintain vigilance in minimizing impurities such as ethylene oxide and 1,4-dioxane. No specific SCCS or FDA regulatory status was identified for PEG-114 POLYLACTIC ACID in the provided research data.
