Gelatin Bloom and Percentage for Blackhead Peel-Off Mask

Based on your question about using gelatin for a blackhead peel-off mask, here is some information regarding gelatin bloom numbers, usage percentage, and your proposed formula.

Bloom number is a measure of the gelling strength of gelatin. A higher bloom number indicates a stronger gel. For a peel-off mask intended to remove blackheads, a stronger gel that forms a cohesive film is generally desired for effective peeling action.

While Gelatin 160 Bloom can form a gel, gelatin with higher bloom numbers such as Gelatin 200 Bloom, Gelatin 250 Bloom, or Gelatin 300 Bloom might provide a stronger, more effective film for peeling.

Regarding the percentage, 5% gelatin in your proposed formula is likely too low to create a strong enough film to effectively pull out blackheads. For peel-off masks using gelatin, a higher concentration is typically needed, often in the range of 10-20% or even higher, depending on the desired peel strength and the specific bloom number used. You would likely need to increase the gelatin percentage significantly from 5% to achieve a functional peel-off mask.

Looking at your formula:

• Water (93.2%) is the solvent, which is appropriate.
• Gelatin 160 Bloom (5%) - As mentioned, the percentage is likely too low for effective peeling. Consider increasing this.
• Titanium (1%) - Assuming this is Titanium Dioxide, it is typically used as a white pigment or opacifier. It is not usually included in a blackhead removal mask and may interfere with the film-forming properties of the gelatin or the mask's ability to adhere and peel effectively. It is likely unnecessary for this application.
• Phenoxyethanol (0.8%) is a common preservative and is appropriate for preventing microbial growth in the water-based formula.

In summary, to make a more effective blackhead peel-off mask using gelatin, you should consider using a gelatin with a higher bloom number for a stronger gel and significantly increase the percentage of gelatin in your formula. The inclusion of Titanium is likely not beneficial and could be omitted.
