Questions about Activated Resorcinol S, Full & Lift™, and Pentylene Glycol in Formulations

Asked by: last_psychedelic On: December 30, 2015 Product Type: Cosmetics

Question

I have questions about several ingredients for my formulations:

  • Can Activated Resorcinol S (water-soluble version) be used with PE-1 Aqua?
  • When dissolved in a gel formula, should Activated Resorcinol S result in a clear product?
  • Does Full & Lift™ dissolve in water, oil, or the formula base (gel/cream) directly? Is there a risk of precipitation if the formula base isn't sufficiently thick?
  • Can Full & Lift™ be used with PE-1 Aqua? If not, what is an alternative ingredient for enhanced penetration?
  • What is the difference in results between Full & Lift™ and Lift-Now™ (permanent vs. temporary)?
  • Can Pentylene Glycol help carry oil-soluble ingredients into the skin?
  • How does Pentylene Glycol affect sunscreen performance?
  • Will Pentylene Glycol feel sticky on oily skin?
  • Can Pentylene Glycol be used in a sunscreen formula that uses chemical UV filters?
  • Also, is it generally advisable to add nourishing ingredients like Aloe Vera Extract to sunscreen formulations?

Answer

Formulation Questions Answered

Here are the answers to your questions regarding specific ingredients:

Activated Resorcinol S and PE-1 Aqua

The new water-soluble Activated Resorcinol S, which is the standard Activated Resorcinol that has undergone encapsulation to become water-soluble, cannot be used with PE-1 Aqua. This is because PE-1 Aqua is designed to enhance the penetration of only water-soluble ingredients, and while Activated Resorcinol S is water-soluble due to encapsulation, its core is still oil-soluble.

When dissolved in a gel formula, Activated Resorcinol S should result in a clear product.

Full & Lift™

Full & Lift™ is described as dissolving within the formula base (gel or cream) rather than directly in water or oil. This indicates that it disperses within the formula. If the formula base is not sufficiently thick, it is possible that the ingredient could precipitate.

Full & Lift™ cannot be used with PE-1 Aqua because it does not dissolve in water. For enhanced penetration, using Pentylene Glycol at 4-5% is recommended instead.

The mechanism of action for Full & Lift™ is significantly different from Lift-Now™. Full & Lift™ provides permanent results, although they take longer to become visible. In contrast, Lift-Now™ provides temporary results that are seen quickly.

Pentylene Glycol

Yes, Pentylene Glycol can help carry oil-soluble ingredients into the skin.

Pentylene Glycol enhances sunscreen performance by helping to disperse the sunscreen ingredients more evenly across the skin's surface and improving their adhesion to the skin.

When used at a low concentration (not exceeding 5%), Pentylene Glycol should not feel sticky on oily skin.

Important Note: If your sunscreen formula uses chemical UV filters, it is best to avoid using Pentylene Glycol. This is because Pentylene Glycol's penetration-enhancing properties could potentially cause the chemical UV filters, which are intended to remain on the skin's surface to absorb UV radiation, to be absorbed into the skin instead.
