When purchasing calcium stearate for sale, buyers should consider various factors to ensure they get the right products to suit their clients' needs. Here are the key factors:
Purity and quality
Buyers should settle for stearate with high levels of purity, especially if their clients intend to use the compound for food, cosmetic, or pharmaceutical purposes. Business owners should also look for stearates with pharmaceutical grades. These grades usually undergo intense testing to eliminate any potentially harmful substances. When considering cosmetic applications, buyers should ensure they get high-quality calcium stearate. This chemical typically acts as an emulsifier and a thickener in lotions and creams. For industrial uses, buyers can consider technical grade stearates. Usually, these compounds are efficient but may not have the same level of purity as food or pharma grades.
Particle size
Usually, stearate with fine particle sizes is ideal for certain applications, especially in pharmaceuticals and cosmetics, where texture is an important factor. Additionally, in plastic manufacturing, larger particle sizes can be more effective as they improve the chemical’s dispersion in the polymer matrices. When selecting, buyers should consider the application their clients intend to use the stearate in.
Source and sustainability
Business owners should get stearate produced from renewable resources such as vegetable oils. This is if they intend to market it for food and cosmetic uses. They should also ensure they get the stearate from suppliers who adhere to eco-friendly practices. This makes them more attractive to environmentally-conscious businesses. For clients with specific dietary requirements, calcium stearate suppliers who use palm oil alternatives, like rapeseed oil, can be more appealing. At times, palm oil can have a negative environmental effect and is linked to deforestation.
Consistency
In industrial applications, buyers should select stearate from the same batch to guarantee chemical consistency in their clients’ manufacturing processes.
