Coty Inc. recently filed a patent for a new eye cream formulation that utilizes innovative ingredients to improve skin care results. This formulation is designed for targeted eye care and is guaranteed to deliver a range of benefits from anti-aging to moisturizing while addressing specific consumer demands for a clean, aesthetically pleasing product. The purpose is
This patent advancement is noteworthy for cosmetic and personal care manufacturers as it exemplifies a sophisticated approach to formulation development that combines functionality and sensory appeal.
Main components and their roles
The eye cream’s formula is a proprietary blend of two sodium polyacrylates in a specific 3:1 ratio, which the company claims balances to improve spread, texture, and ease of application. The patent application explains that this combination “acts as a gelling agent, providing substantial benefits to the overall formulation,” imparting qualities such as smooth application and a non-stick finish.
According to Coty, “the ratio and combination of the two polyacrylates provides excellent elongation and a beneficial blurring effect,” making it suitable for application to sensitive eye areas.
The formula contains additional texture enhancers such as boron nitride powder and pearlescent pigments, which contribute to the cream’s smooth application and subtle luminescence. Boron nitride powder is intended to improve adhesion and allow the formulation to glide easily on the skin without a sticky feeling. Meanwhile, pearlescent pigments impart reflective properties that create a “healthy-looking eye zone area” and support a glowing, hydrated look.
Advanced surfactant systems and clean beauty standards
Coty’s formulations incorporate carefully selected surfactant systems, including biodegradable branched surfactants and polyglyceryl fatty acid esters. As outlined in the patent, these surfactants are designed to stabilize the formulation and increase elongation without compromising skin compatibility.
The choice of surfactant is in line with Coty’s goal to create “virtually PEG-free” products that meet growing consumer demand for clean, environmentally friendly skin care. The patent lists additional surfactant options such as polyglyceryl-3 diisostearate, polyglyceryl-4 caprate, and other plant-based options, further increasing its appeal to environmentally conscious consumers.

Formulation process and stability testing
The formulation process of eye creams is also an important aspect. Coty’s patent describes the gradual combination of oil and water phases and precise temperature control essential for stable emulsions. The process involves heating the aqueous phase to 80°C, stirring, adding the powder in portions, then mixing with the oil phase, and cooling the formulation.
According to the patent, this controlled process ensures consistency in texture and stability, which is important for products targeting sensitive eye areas.
Coty’s eye cream testing protocol includes rigorous evaluation of texture and sensory properties. The tests cover aspects such as hardness, adhesion, gloss and elongation and are evaluated before, during and after application.
“Our samples perform well against these sensory markers,” the filing states, demonstrating that Coty’s formulation meets consumers’ expectations for high-quality, easy-to-apply products that leave a pleasant skin feel. This indicates that the company is expected to meet the requirements.
Impact on cosmetic manufacturers and suppliers
This patent provides valuable insight for cosmetic manufacturers and suppliers, as it shows a trend toward high-performance, clean, and multifunctional formulations. Coty’s focus on clean ingredients, biodegradability, and improved texture aligns with the market’s broader shift toward sustainable, luxurious, and sensory-pleasant products.
Branched surfactants and other plant-based ingredients could encourage suppliers to expand their portfolios with eco-friendly ingredients that can stabilize and enhance skin care formulations.
Additionally, Coty’s dedication to testing and refining the sensory aspects of eye creams highlights the importance of texture and feel in consumer products, especially in the premium skin care market. By employing advanced materials and precise testing protocols, Coty has created formulations that deliver visible skin care benefits and improve user experience, an important consideration in modern product development.
