W/O Emulsifiers: Professional Solutions for Restoring Moisturising Texture

W/O (water-in-oil) emulsifiers, with their ‘high barrier properties and strong moisturising power,’ serve as the core ingredient for creating moisturising creams and repair products. This system, which encapsulates water droplets within a continuous oil phase, forms a long-lasting moisture-locking film on the skin's surface, making it particularly suitable for dry skin care and product development during autumn and winter seasons.

Technological Innovation and Performance Advantages

Our W/O emulsifiers utilise novel polyglycerol fatty acid esters as core components, employing a unique emulsification process to uniformly disperse water phase droplets with particle sizes controlled between 2-5μm, forming a thixotropic gel structure. The product offers three core advantages:

4. Exceptional moisture-locking capability: The continuous oil phase film reduces transepidermal water loss (TEWL) by up to 60%. After applying a cream containing this emulsifier, skin moisture levels remain stable for up to 8 hours;

5. High oil phase loading capacity: It can accommodate 40%-70% oil phase components (such as shea butter or petroleum jelly), enhancing product moisturisation and barrier properties;

6. Low-temperature stability: After -15°C freezing tests, the emulsion structure remains intact upon thawing with no emulsion breakdown or phase separation, making it suitable for extreme environments.

Scenario-based application solutions

- Anti-dryness care: Adding 2%-4% to repair creams, combined with ceramides and squalane, can quickly alleviate dryness and flaking in desert-like skin. Clinical tests show a 45% increase in moisturising efficiency within 24 hours;

- Lip care: When used in lip balms or lip masks, it forms a long-lasting moisturising barrier to reduce moisture evaporation from the lips, improving dryness and peeling, with a satisfaction rate of 91%;

- Body care: When combined with natural plant oils to formulate body lotions, it enhances product moisturisation and spreadability, reducing skin dryness scores by 62% during autumn and winter seasons.
