INGREDIENT OVERVIEW

PEG-40 Hydrogenated Castor Oil

PEG-40 hydrogenated castor oil is a solubiliser used in cosmetic formulations to disperse oils and fragrance into water-based systems. It is widely used in toners, mists, cleansers, and serums where clarity and improved sensory are required.

Our PEG-40 hydrogenated castor oil is supplied as a cosmetic-grade liquid with high active content (92.12%) and controlled acid and hydroxyl values, supporting consistent formulation performance.

In formulation, it provides effective solubilisation with a smoother sensory profile compared to traditional polysorbates.

Troubleshooting

Cloudiness → adjust ratio vs oil
Separation → insufficient solubiliser
Too heavy feel → reduce level
Foam suppression → adjust surfactants

COMPARISON & ALTERNATIVES

Polysorbate 20 → lighter, more basic
Polysorbate 80 → heavier, higher oil load
Full emulsifier → glyceryl stearate citrate

SENSORY PROFILE

PEG-40 hydrogenated castor oil provides a smoother, more refined sensory profile compared to polysorbates. It helps reduce heaviness and improves overall formulation feel. Sensory outcome is
formulation-dependent; bench testing is recommended.

STORAGE & HANDLING

Store in a cool, dry place, protected from heat, moisture, and direct light.
Keep container tightly sealed when not in use.
Shelf life: 2 years when properly stored

PRODUCT SAFETY

Low irritation potential when used within recommended levels.
Suitable for leave-on and rinse-off systems.
Keep out of reach of children.
Avoid inhalation of dust. Use appropriate PPE during handling and formulation.
Refer to Safety Data Sheet (SDS) contained within documents tab.
