Is hyaluronic acid oil soluble?

Hyaluronic Acid (HA), known as an ideal natural moisturizing factor, can bind up to 1000 times its own weight in water molecules and is widely applied in the cosmetic industry.

1. Pain Points of Conventional Hyaluronic Acid: Water-soluble Limitations for Oil-based Formulations

Formulators have long been faced with a persistent technical challenge: conventional hyaluronic acid is a typical water-soluble moisturizing ingredient that can only dissolve and disperse stably in aqueous systems.

Many cosmetic products, especially color cosmetics, consist largely of oil-soluble components, and some are even anhydrous formulations. Such oil-based cosmetics tend to cause skin dryness, requiring suitable moisturizing factors to relieve discomfort. However, the high hydrophilicity of HA prevents it from being directly incorporated into oil phases. This represents a key industry bottleneck that has long restricted the addition of high-activity Sodium Hyaluronate to color cosmetics, oily serums, ointments and lipsticks.

When conventional Sodium Hyaluronate is introduced into oil-based systems, precipitation, phase separation and deactivation may occur. It fails to deliver moisturizing benefits and compromises overall formulation stability, resulting in poor product texture and shortened shelf-life. Consequently, its adoption in premium oil-based skincare and skincare-infused color cosmetics has been greatly limited.

Ⅱ. Core Process Advantages: Exclusive Technology Grants Hyaluronic Acid Brand-New Oil-Phase Compatibility

We apply a modification process using oligo sodium hyaluronate together with plant-sourced oils (castor seed oil, hydrogenated castor oil, tocopherol). While fully preserving the native moisturizing, repairing and anti‑aging activities of hyaluronic acid, this technology greatly enhances the affinity and binding capacity of the raw material with various oils.

Verified by multiple rounds of formulation compatibility tests, Oil Soluble Sodium Hyaluronate achieves high compatibility with mainstream cosmetic oils used in skincare and color cosmetics without incompatibility reactions. It can be directly incorporated into fully-oily anhydrous formulations, high-oil low-water emulsions, as well as wax-oil composite solid color-cosmetic systems. Throughout production stirring, high-temperature homogenization and long-term storage, issues such as caking, white precipitation, oil-water phase separation and whitening stratification will not occur. NewOilHA® Oil Soluble Sodium Hyaluronate fundamentally improves the stability of finished formulations, optimizes the spreading feel and fine texture of ointments, oil-based products and powder-type goods, and addresses common drawbacks of conventional oil-based formulas including dry feel, heavy texture and poor spreadability.

2.1 Product Morphology, Physicochemical Indicators and Core Performance

2.1.1 Basic Appearance and Content Parameters

NewOilHA® Oil-dispersible Sodium Hyaluronate appears as a uniform milky-white to pale-yellow paste or semi-solid at ambient temperature, with a smooth touch free of particles and grit. The content of active sodium hyaluronate is stably maintained within 25%-35%. Sufficient loading of active ingredients enables prominent moisturizing and repairing effects at low addition levels.

2.1.2 Three Key Physicochemical Performance Advantages

1) Excellent Skin Affinity and Transdermal Absorption

Ultra-low-molecular-weight sodium hyaluronate is selected as the core functional carrier. Thanks to its tiny molecular size, it quickly adheres to the stratum corneum upon application and penetrates through the superficial barrier into the superficial dermis. Different from high-molecular-weight HA that only stays on the skin surface, it delivers continuous hydration and repair from inside out and ameliorates dry and rough skin with long-term use.

2) Superior Long-term Storage Stability

Solid cosmetics based on waxes and oils commonly suffer from two defects: oil blooming and cracking after prolonged storage. This raw material evenly intersperses between wax and oil molecules to stabilize the spatial structure of the system. Finished products are resistant to oil exudation, swelling and cracking, greatly improving the appearance stability of color cosmetics over shelf life.

3) No Interference with Finished-Product Viscosity and High Formulation Flexibility

NewOilHA® Oil Soluble Sodium Hyaluronate’s addition will not significantly raise or reduce the overall viscosity of essential oils and cream foundations. Formulators are free to pair it with thickeners and rheology modifiers to develop diverse textures, ranging from light‑weight flowing oils and rich repairing balms to silky matte lipsticks, delivering extremely high formulation flexibility.

2.2 Core Skincare & Color-Cosmetic Benefits and Full-category Application Scenarios

2.2.1 Long-lasting Moisture Lock and Significant Reduction of Transepidermal Water Loss (TEWL)

The core skincare function of NewOilHA® Oil-dispersible Sodium Hyaluronate is to build a dual-layer moisture-locking protective system. Upon application, the oil carrier forms a thin, breathable hydrophobic film on the skin surface to block external dry air from depleting epidermal moisture. The internal ultra-low-molecular-weight HA penetrates into the dermis to capture and retain water molecules inside the skin, effectively lowering TEWL values. It solves tightness, flaking and dry-pull sensation caused by oil-only skincare and makeup products.

NewOilHA® Oil Dispersed Sodium Hyaluronate delivers remarkable improvements for dry skin in cold seasons, dehydration from prolonged makeup wear, chapped lips and dry fine lines around eyes. Long-term application strengthens the skin barrier’s inherent moisture-locking capacity and mitigates dryness damage induced by external environments.

2.2.2 Empower Skincare-infused Color Cosmetics and Expand Access of Moisturizing Actives into Oil-based Formulations

As a milestone innovation for the industry, NewOilHA® Oil Dispersed Sodium Hyaluronate enables high-activity natural hyaluronic acid to be fully deployed in anhydrous color cosmetics. It breaks the long-established perception that makeup only provides cosmetic coverage without skincare benefits. Lipsticks, foundations, cushion compacts, pressed powders and other decorative cosmetics can now incorporate moisturizing and repairing functions, supporting differentiated skincare-infused makeup launches and boosting product competitiveness.

2.2.3 Stabilize Wax-oil Formulations, Optimize Sensory Experience and Improve All-day Makeup Performance

For wax-based solid cosmetics such as lipsticks, lip balms, pressed powders and concealer sticks, oil dispersible sodium hyaluronate evenly balances the spatial distribution of waxes and liquid oils and inhibits oil migration and exudation.

Meanwhile, its mild film-forming capacity generates a soft, hydrating layer on skin. It fills fine dry lines and skin texture, enhances foundation and cushion adherence, and reduces caking, patchiness and floating makeup. The film features moderate water‑sweat resistance and resists makeup transfer upon minor exposure to sweat and mist, extending all-day wear and delivering long‑lasting makeup without dry-pull feeling.

Ⅲ. Conclusion: Is Hyaluronic Acid Oil Soluble?

The answer is yes, with qualification: specially processed oil soluble Sodium Hyaluronate enables stable incorporation within oil-phase and anhydrous formulations.

This technical breakthrough opens new creative possibilities for cosmetic formulators. Star moisturizing ingredient Oil Soluble Sodium Hyaluronate can now be added to lip balms, lip glosses, liquid foundations, pressed powders, mascaras, and other oily or anhydrous products, realizing the product concept of “makeup with skincare benefits”.

Looking ahead, with the launch of more hyaluronic acid derivatives and maturing technical routes, the application boundaries of hyaluronic acid/Sodium Hyaluronate within cosmetics will keep expanding.
