Glyceryl Caprylate (Liquid) is a multifunctional co‑emulsifier and emollient used to improve emulsion stability, support solubilization of lipophilic ingredients, and boost preservative systems in leave‑on formulas.
It is commonly used as a “preservative booster” (not a stand‑alone preservative) and can also help improve skin feel by reducing greasiness and supporting a lighter after‑feel.
This liquid grade is convenient for processing and dosing; it is typically used at low percentages and is generally compatible across common cosmetic pH ranges.
Product Description: Glyceryl Caprylate is a lipophilic glyceride (C8) widely used in cosmetic formulations as a co‑emulsifier and functional additive. In emulsions, it can support interfacial stability and help keep oils, fragrances, and other hydrophobic components better dispersed. In preservative systems, it is often paired with other approved preservatives to help broaden performance, particularly in leave‑on products.
Usage: Creams and lotions, serums, leave‑on skin care, lip products, and other emulsions where improved stability and preservation support are desired.
Mixing method:
- Emulsions: add to the oil phase (warm if needed) and emulsify as usual; it can also be pre‑dissolved in oils/esters and added in cool‑down if the system allows.
- Solubilization: pre‑blend with the oil/fragrance phase and compatible solubilizers before introducing into the main batch.
- Preservative systems: use together with other preservatives; do not rely on this material alone for preservation.
Usage rate: 0.1–1.0%
Product characteristics: Very pale yellow liquid; mild characteristic odor.
Solubility: Oil‑soluble; not directly water‑soluble. Pre‑dissolve in oils/esters or use suitable solubilizers for clear systems.
Notes: Not suitable as a single preservative. Not recommended as the preservative system for cleansing/surfactant formulas.
