Calcium phosphate, 100 g

Calcium Phosphate: A Versatile Ingredient for Cosmetic Formulations

Calcium phosphate, encompassing various calcium salts of phosphoric acid, is a widely used ingredient in diverse industries, including cosmetics. While the provided information mentions dicalcium phosphate as the most popular form, the product being sold is specified as tricalcium phosphate (Tricalcium Phosphate or TCP). This description will focus on the cosmetic applications of tricalcium phosphate. This white or slightly grayish powder offers several benefits in cosmetic formulations, primarily as an abrasive, filler, and stabilizer.

Why Choose Tricalcium Phosphate for Cosmetics?

• Gentle Abrasion (in Toothpastes): Tricalcium phosphate provides effective yet gentle cleaning action in toothpastes, helping to remove plaque and surface stains without causing excessive abrasion to tooth enamel.
• Filler and Texturizer: In decorative cosmetics, it acts as a filler, improving the texture and application of powders, eyeshadows, and other similar products. It creates a smoother, more even application.
• Formula Stabilization: Tricalcium phosphate can contribute to the stability of cosmetic formulations, helping to prevent separation and maintain a consistent texture over time.

Applications of Tricalcium Phosphate in Cosmetics:

Tricalcium phosphate finds its primary cosmetic applications in:

• Oral Care (Toothpastes and Tooth Powders): This is where it is most widely used in concentrations from 20% to 50%.
• Decorative Cosmetics (Powders, Eyeshadows, Blushes): Here, it is used in much lower concentrations, typically ranging from 1% to 10%.

Detailed Breakdown of Cosmetic Applications:

• Toothpastes and Tooth Powders: Tricalcium phosphate functions as a mild abrasive, aiding in the mechanical removal of plaque, food debris, and surface stains from teeth. It is crucial that the abrasivity is controlled to prevent damage to the enamel. The particle size of the tricalcium phosphate used in toothpastes is carefully controlled to achieve this balance between cleaning efficacy and gentleness.
• Face and Body Powders: In loose and pressed powders, tricalcium phosphate acts as a filler and texturizer. It improves the flow and spreadability of the powder, creating a smoother, more even application on the skin. It also contributes to the opacity and coverage of the powder.
• Eyeshadows and Blushes: Similar to its use in face powders, tricalcium phosphate in eyeshadows and blushes helps to create a smooth, blendable texture and improves color payoff. It can also contribute to the adherence of the product to the skin.

Cosmetic Recipe: Homemade Tooth Powder

• Ingredients:

  • 30g Tricalcium Phosphate
  • 10g Baking Soda (Sodium Bicarbonate)
  • 5g Xylitol (natural sweetener and anti-caries agent)
  • A few drops of Peppermint Essential Oil (for flavor and breath freshening – use with caution and dilute well)

• Instructions:

  1. Thoroughly mix all dry ingredients in a clean, dry container.
  2. Add the essential oil drop by drop, mixing well after each addition to ensure even distribution.
  3. Store in an airtight container.

Recommendations for Use (Tricalcium Phosphate in Cosmetics):

• Particle Size: The effectiveness and safety of tricalcium phosphate in toothpastes are highly dependent on the particle size. Using excessively large particles can lead to enamel abrasion.
• Concentration: Adhere to the recommended usage levels (20-50% in toothpastes, 1-10% in decorative cosmetics). Exceeding these levels could potentially lead to issues such as excessive abrasion in oral care products or a dry, cakey texture in powders.
• Patch Test (for Decorative Cosmetics): Although generally considered safe, it is always recommended to perform a patch test when using a new cosmetic product, especially if you have sensitive skin.
• Solubility: Due to its poor solubility in water, tricalcium phosphate is typically used in anhydrous (water-free) formulations like powders or in suspensions within toothpastes.
• Testing for Sensitivity: As mentioned in the original product information, testing for individual sensitivity is recommended before widespread use.
