HYDROGENATED VEGETABLE GLYCERIDES CITRATE.

Valuable CAS 97593-31-2 / LIGHT STABILIZER, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Hydrogenated Vegetable Glycerides Citrate is a multifunctional ingredient derived from vegetable oils, recognized for its role in enhancing skin hydration and product stability. It primarily serves as an emollient, creating a protective barrier to smooth skin texture and reduce moisture loss, while also functioning as an effective emulsifier to maintain stable formulations.

Science

Mechanism of Action

This ingredient operates on multiple levels to benefit both skin and product integrity. As an emollient, it forms a fine, protective layer on the skin's surface, effectively locking in moisture, softening the complexion, and improving overall skin feel by preventing transepidermal water loss. Its emulsifying properties stem from its amphiphilic structure, possessing both lipophilic (oil-loving) and hydrophilic (water-loving) components. This allows it to significantly lower the interfacial tension between immiscible liquids, such as oil and water, thereby facilitating the creation and stabilization of emulsions common in creams and lotions. Furthermore, it acts as a skin conditioning agent, helping to maintain skin health, and contributes to formulation stability, extending the shelf life of cosmetic products.

Stability

While a specific optimal pH range for Hydrogenated Vegetable Glycerides Citrate is not identified, cosmetic formulations generally target a slightly acidic pH, typically around 5.5, to support skin barrier health and product stability. The ingredient exhibits broad compatibility, integrating well with nonionic, cationic, and anionic components. It is noted to form stable colloidal associations with cationic polymers, and even at low concentrations, it can effectively maintain stable colloidal suspensions. Additionally, it helps to mitigate the whitening effect that can occur in some formulations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific review for Hydrogenated Vegetable Glycerides Citrate. However, related compounds like glycerin and hydrogenated cottonseed glycerides have been evaluated and deemed safe under current usage practices, provided impurity levels are controlled. The ingredient is broadly considered non-irritating, with a low concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity, as indicated by EWG's Skin Deep database. It is also recognized by the FDA as a food additive (under 'Citric and Fatty Acid Esters of Glycerol') with functional uses as an emulsifier and stabilizer. While generally well-tolerated, the potential for irritation may increase when formulated with other known problematic ingredients.
