FAQs:

Q1. What is the INCI name of LK-Q5?
A: The INCI name of LK-Q5 is Cyclopentasiloxane (and) Trimethylsiloxysilicate.

Q2. What is the primary functional role of LK-Q5 in cosmetic formulations?
A: LK-Q5 functions primarily as a film-forming agent. Upon evaporation of cyclopentasiloxane, the Trimethylsiloxysilicate resin forms a continuous, durable, and hydrophobic film on the skin or hair. This film enhances long wear, water resistance, transfer resistance, and overall formulation durability while maintaining a smooth, non-tacky finish

Q3. Is LK-Q5 compatible with pigments used in color cosmetics?
A: Yes. LK-Q5 is compatible with hydrophobic and surface-treated pigments commonly used in long-wear cosmetic systems.

Q4. How does LK-Q5 support long-lasting performance in formulations?
A: Upon evaporation of cyclopentasiloxane, the silicone resin forms a durable, adherent film on the skin, enhancing wear resistance and product longevity.

Q5. What is the film-forming mechanism of LK-Q5?
A: LK-Q5 deposits a high molecular weight silicone resin film after the volatile carrier evaporates, creating a continuous, flexible, and transfer-resistant layer.

Q6. Is LK-Q5 compatible with natural oils in formulations?
A: No. LK-Q5 shows limited compatibility with natural oils and is better suited for silicone-based systems.

Q7. Does LK-Q5 leave a tacky or sticky feel after application?
A: No. It forms a smooth, non-tacky film, contributing to a clean and comfortable after-feel.

Q8. Does LK-Q5 enhance wear in high-humidity or sweat-prone conditions?
A: Yes. Its hydrophobic film provides resistance to moisture, sweat, and humidity, making it suitable for long-wear and outdoor formulations.

Q9. How does LK-Q5 affect the sensory profile of formulations?
A: The cyclopentasiloxane carrier ensures easy spreadability during application, while the residual resin film delivers a lightweight, smooth finish without heaviness. This improves the overall sensory profile of product

Q10. How the LK-Q5 be used across different color cosmetic formulations?
A: Yes. It is suitable for use in lip products, eye cosmetics, and complexion products where long wear, water resistance, and film integrity are required.

Q11. Does LK-Q5 contribute to film flexibility or brittleness?
A: LK-Q5 forms a flexible film that maintains adhesion without cracking, supporting comfortable long wear.
