INGREDIENT OVERVIEW

Glycerin (USP)

Vegetable glycerin (USP) supplied as a high-purity, vegetable-derived grade selected for clarity, consistency, and predictable performance in cosmetic formulation.

Each batch is supported by a Certificate of Analysis (COA) verifying identity, purity, and compliance with USP standards — supporting reproducible results from small-scale development through to production.

Solubility: Water soluble
Typical use level:
- Leave-on: 2–6%
- Rinse-off: 2-10%
- Above ~5–7%, increased tack may be noticeable depending on the overall formula design.
Starter: 1-10%

FORMULATION NOTES

Processing notes

Add to the water phase with mixing until fully uniform. Suitable for both cold-process and heated systems. Compatible with a wide range of formulation types, including gels, emulsions, and surfactant-based systems.

At higher use levels, glycerine may influence viscosity and overall sensory feel; adjust rheology modifiers and emollient balance as needed.

Compatibility notes

Generally compatible with most cosmetic ingredients and preservative systems.
High glycerine levels may increase tack in leave-on products; balance with lower-tack humectants (e.g. pentylene glycol, propanediol) and suitable emollients.
In surfactant systems, glycerine can improve post-rinse skin feel but may affect viscosity.

pH notes

Stable across typical cosmetic pH ranges (approx. 3–10).

Formulation examples

Hydrating toner (2–5%)
Humectant gel serum (3–8%)
Lotion humectant phase (2–6%)

Troubleshooting

Too Tack/stickiness → lower % glycerin/ add a secondary humectant with lower tack (pentylene glycol /propanediol)/ or rebalance emollients/rheology.
Viscosity changes → adjust polymer/rheology
Surfactant thinning/thickening → salt curve / adjust surfactant ratios

COMPARISON & ALTERNATIVES

Less tack: propanediol / pentylene glycol
More “cushion”: sodium PCA
For preservation boost: pentylene glycol (dual role)

SENSORY PROFILE

Glycerine contributes a smooth, hydrated skin feel at low to moderate use levels.
At higher concentrations (typically above ~7–10%), tackiness may become noticeable, particularly in leave-on formulations with minimal emollient content.
Perceived tack can be reduced by:
• pairing glycerine with lower-tack humectants (e.g. propanediol or pentylene glycol)
• incorporating suitable emollients or light esters
• optimising polymer or emulsifier selection
Sensory performance is formulation-dependent; bench testing is recommended to determine the optimal balance for the intended product type.

STORAGE & HANDLING

Store tightly closed in a cool, dry place away from direct sunlight.
Glycerin is hygroscopic (draws moisture from the air); keep containers sealed between uses to maintain consistency and minimise water uptake.
Warm slightly (in a warm water bath) if needed to improve pourability in cooler conditions.

PRODUCT SAFETY

Low irritation potential. Suitable for leave-on and rinse-off systems when used within recommended levels.
