Long-Lasting, Non-Transfer Gloss Top Coat Formulation

To create a long-lasting, non-transfer, shiny lip gloss top coat, the key is to utilize film-forming ingredients that create a durable layer on the lips.

One suitable ingredient for this purpose is Ethylcellulose.

Ethylcellulose acts as a film former in oil-based cosmetic formulas. When combined with volatile oils (oils that evaporate quickly), it dissolves and forms a solution. Upon application to the lips, the volatile oils evaporate, leaving behind a thin, flexible film of Ethylcellulose. This film provides the desired long-lasting and non-transfer properties, helping the gloss adhere to the lips and resist smudging or transferring onto surfaces like masks.

To maintain a shiny finish, the formulation should also include non-volatile emollients or oils that remain on the lips after the volatile carriers have evaporated.

Therefore, a typical formulation approach for a product like this would include:

• Film Former: Such as Ethylcellulose, to build the durable layer.
• Volatile Carrier: Oils like Isododecane or Isoparaffin, which dissolve the film former and evaporate after application.
• Non-Volatile Emollients/Oils: To provide lasting shine and a comfortable feel.
• Other Additives: Such as colorants (if desired), fragrances, and antioxidants.

By carefully formulating with these components, you can achieve a gloss that dries to a transfer-resistant film while retaining a high-gloss look.
