What Is Citrus Aurantium Sinensis Fiber?

Citrus Aurantium Sinensis Fiber is derived from orange peel and functions primarily as an emulsion stabiliser in skincare formulations. It is a natural polysaccharide—specifically a form of pectin—that helps prevent the separation of oil and water phases in creams and lotions, maintaining product integrity over time.

As a stabilising agent, this ingredient works behind the scenes to improve the physical stability of formulations rather than providing direct skincare benefits. Its use supports product performance, ensuring that creams remain homogeneous and pleasant to use throughout their shelf life.

How It Works

Citrus Aurantium Sinensis Fiber is a polysaccharide that acts as a physical stabiliser in emulsions. It works by increasing the viscosity of the water phase and forming a network structure that slows the movement of oil droplets, reducing their tendency to coalesce and separate.

This mechanism helps maintain the fine dispersion of oil droplets within the aqueous base, which is essential for the texture, spreadability and shelf stability of emulsified products like creams and serums.

Clinical Evidence & References

Research suggests that orange peel-derived compounds, including pectin fibres, can support emulsion stability in skincare formulations. One study found that orange fibres, when combined with other thickening agents, created more stable emulsions with minimal particle growth during storage, though sensory acceptance varied depending on the formulation.

Beyond stabilisation, compounds found in orange peel—such as polymethoxyflavones—have shown potential photoprotective properties in laboratory studies, including suppression of UV-induced collagen breakdown. However, the concentration of these bioactive compounds in stabilising fibres is typically lower, and direct skin benefits would depend on the overall formulation and concentration used.

How to Use

This ingredient is incorporated by the manufacturer during formulation, so there are no specific application instructions for consumers. If you use a product containing this stabiliser, simply apply as directed. Its presence is most noticeable in its effect on product consistency and stability rather than in how you use the product.

Safety & Precautions

Citrus Aurantium Sinensis Fiber is generally well-tolerated and derived from food-grade orange peel, making it a low-risk ingredient for most skin types. Those with citrus sensitivities should check the full ingredient list, though stabilising fibres are unlikely to cause issues.
