Comparison: Astaxanthin Liquid (Stabilized, Crystal Clear) vs. Astaxanthin Powder

Choosing between Astaxanthin Liquid (Stabilized, Crystal Clear) and Astaxanthin Powder (Water Dispersed) depends on your specific formulation goals, particularly the desired appearance and the level of stability required.

1. Astaxanthin Liquid (Stabilized, Crystal Clear)

This version is specifically engineered for high-end cosmetic formulations where aesthetics and stability are priorities.

• Appearance: Provides a crystal-clear, bright red result. It is ideal for clear serums, toners, or gels.
• Stability: Highly stabilized. It is resistant to heat (tested at 40°C for over a month without color change) and oxidation.
• Ease of Use: Being water-soluble and pre-stabilized, it is easier to incorporate into water-based formulas.
• Requirement: To maintain its 2-year shelf life, the final formula's pH must be adjusted to 4.0–4.5.
• Usage Rate: 0.1–5%.

2. Astaxanthin Powder (Water Dispersed)

This is a more traditional form of Astaxanthin, often used when clarity is not the primary concern.

• Appearance: It is water-dispersible, not water-soluble. This means it will result in a cloudy or opaque (semi-liquid) appearance in the formula.
• Stability: It is more sensitive to light and heat. It is highly recommended to add additional stabilizers like ActiveProtec™ OX and ActiveProtec™ UV to prevent the color from fading or the active ingredient from degrading.
• Concentration: Available in 2.0% and 2.5% concentrations.
• Usage Rate: 0.1–1%.

Summary Comparison

Recommendation:

• Choose the Liquid (Stabilized, Crystal Clear) if you want a professional, clear product with long-term color stability and ease of formulation.
• Choose the Powder if you are making an opaque cream or lotion and are prepared to add extra stabilizers to protect the formula.
