Answer
How to Use Creatine 100 Powder
Creatine 100 is a high-purity powder suitable for use in skin and hair care products. It is mixed into the water phase of your formulation.
- Mixing Method: Dissolve the Creatine 100 powder in water. It can withstand heat up to 80°C for no more than 15 minutes during mixing.
- Usage Rate: The recommended usage rate is 1%, with a range of 0.5% to 1.4%. The solubility limit in water is also around 1.4%, so using 1% ensures it dissolves properly.
Calculating 1% Concentration
To achieve a 1% concentration, you need 1 gram of Creatine 100 powder for every 100 grams of your final product (water + Creatine). Since the density of water is close to 1 g/ml, you can approximate this as 1 gram per 100 ml of water for simple water-based solutions like a hair spray.
- Example: To make 100 grams of a 1% Creatine solution, you would mix 1 gram of Creatine 100 powder with 99 grams of water.
- Example: To make 50 grams of a 1% Creatine solution, you would mix 0.5 grams of Creatine 100 powder with 49.5 grams of water.
Always weigh your ingredients for accuracy, especially the Creatine powder.
Preservative for Water-Based Solutions
Yes, if you are mixing Creatine 100 powder with water to create a solution like a hair spray, you must include a preservative. Water-based formulations are highly susceptible to microbial contamination (bacteria, mold, yeast) over time. A preservative system is essential to prevent spoilage, maintain product safety, and ensure a longer shelf life, especially since a hair spray is typically stored and used repeatedly.
