CelluCap™ RL encapsulates pure retinol for stable formulation: 9% payload, 1-3% use level, and clinically reduced dark spots and improved skin homogeneity.
Encapsulated Pure Retinol: A Stable Way to Formulate with Retinol
Innovating Retinol Usage in Skincare Formulas
Pure retinol is considered the gold standard in skincare for anti-aging formulations. Renowned for its ability to reduce hyperpigmentation, revitalize skin, diminish wrinkles, and promote a youthful complexion, it is a go-to ingredient for cosmetic manufacturers worldwide. However, retinol's sensitivity to light, oxygen, and heat presents significant challenges for formulators. This inherent instability can compromise its efficacy, making it crucial to develop innovative solutions to protect and preserve its powerful benefits.
CelluCap™ RL utilizes Tagra's patented microencapsulation technology to protect retinol by isolating it from environmental factors. The microcapsules remain intact until they are applied to the user's skin, ensuring that the retinol stays stable and effective. This innovative technology preserves retinol's potency throughout the production process and the product's entire shelf life, keeping it active and ready to deliver maximum benefits upon use.
Formulating with CelluCap™ RL
CelluCap™ RL should be incorporated gradually during the final stage of formulation preparation using a simple paddle or anchor-type mixer set at 70–300 rpm. To maintain its integrity, avoid high-shear mixing (such as homogenizers) and temperatures above 50°C. Additionally, there is no need for a nitrogen blanket when formulating with CelluCap™ RL, simplifying the process while ensuring optimal performance.
The Powerful Effect of CelluCap™ RL
CelluCap™ RL underwent an 8-week clinical study involving 22 participants. The tested formulation contained a final retinol concentration of 0.1%. After 56 days (D56) of treatment, results demonstrated a significant reduction in both the number and area of hyperpigmented spots by 18.3% and 18.5%, respectively, compared to baseline values (D0). Additionally, skin homogeneity improved by an impressive 21.5%, highlighting the effectiveness of the formulation in enhancing overall skin appearance.
