Uses
Used in Skin Care Industry:
Calamine is used as a topical treatment for minor skin irritations such as insect bites, poison ivy, poison oak, and sunburn. The zinc oxide in calamine possesses anti-inflammatory and soothing properties, while the ferric oxide provides a pink color. When applied to the skin, it forms a protective barrier, reducing inflammation, itching, and irritation, and promoting the healing of the affected area.
Used in Pharmaceutical Industry:
Calamine is used as an ingredient in various over-the-counter medications and home remedies for skin conditions. Its anti-inflammatory and soothing properties make it an effective treatment for relieving discomfort and promoting healing in minor skin irritations.
Used in Cosmetic Industry:
Calamine is used as an ingredient in some cosmetic products, such as makeup and skincare products, due to its soothing and anti-inflammatory properties. It can help to calm irritated skin and provide a protective barrier, making it suitable for sensitive skin types.
Check Digit Verification of cas no
The CAS Registry Mumber 12196-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,9 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12196-21:
(7*1)+(6*2)+(5*1)+(4*9)+(3*6)+(2*2)+(1*1)=83
83 % 10 = 3
So 12196-21-3 is a valid CAS Registry Number.

Comparison of thermal property and dissolution behavior of synthetic compound and natural hemimorphite
Ding, Zhiying,Yin, Zhoulan,Hu, Huiping,Chen, Qiyuan
, p. 168 - 173 (2010)
A comparison of the thermodynamic properties, crystal structure, thermal characterization and dissolution behavior of the synthetic compound and the natural hemimorphite was made. It was found that the synthetic compound shows the same crystal structure but is poorly crystallized compared with the natural hemimorphite. Both the synthetic compound and natural hemimorphite display the similar characteristics of phase formation during calcination, except that the poor crystallization of synthetic compound leads to the structural reorganization with an intense exothermic peak at 700 °C to form a stable phase after losing structural water at 633 °C. The natural hemimorphite exhibits an endothermic peak at 700 °C for the removal of structural water during TGA/DTA analysis. Although, synthetic compound shows a more rapid dissolution rate than the natural hemimorphite in ammoniacal solution, the final states exhibit the same when they are completely dissolved.
