Review of Gel Formulation for Dry Skin

Hello,

I have reviewed your gel formulation for dry, sensitive skin, targeting moisturization, whitening, and anti-aging.

Ingredient Compatibility

Based on the feedback received, most ingredients are compatible. However, there is a potential issue with the combination of Ammonium Lactate (which has high electrolyte content) and Pro Polymer (Acrylate Crosspolymer) as the gelling agent. The high electrolyte can interfere with Pro Polymer's ability to thicken and form a stable gel. It is recommended to use AnyGel (Dehydroxanthan Gum) as the gelling agent instead, as it is more tolerant to electrolytes.

Regarding the oil phase (5% Coconut Oil and 5% Shea Butter Water), AnyGel has limited capacity to emulsify large amounts of oil. The feedback indicates that 5% Coconut Oil should be fine. You may need to test if 5% Shea Butter Water can be successfully incorporated with AnyGel, or consider adding a small amount of an additional emulsifier if separation occurs.

Recommended pH and Adjustment

The expected pH of this formulation is in the range of 5-7, which is suitable for the skin. Therefore, pH adjustment is not necessary.

Mixing Procedure

Here is a general mixing procedure for this gel formulation, incorporating the recommendation to use AnyGel:

1. Prepare the Water Phase: Combine Water, GlucoBright, Vitamin B3, Panthenol, Lemon Peel Bioferment, Centella Asiatica Extract, Ammonium Lactate, Glycerin, and 1,2 Hexanediol in a container. Stir or mix until all ingredients are dissolved.
2. Add the Gelling Agent: Slowly add AnyGel to the water phase while stirring or mixing continuously until the mixture thickens into a gel.
3. Prepare the Oil Phase: In a separate container, combine Coconut Oil and Shea Butter Water. Gently warm if needed to melt Shea Butter (if it's solid), but avoid excessive heat.
4. Combine Oil Phase with Gel: Gradually pour the oil mixture into the gel phase from step 2 while stirring or mixing continuously until the oil phase is evenly dispersed and incorporated into the gel.
5. Add Extracts and Preservative: Add Aloe Vera Extract and Phenonip P4 to the gel. Stir or mix until well combined.
6. Check Consistency and pH: Check the consistency of the gel and measure the pH (which is expected to be 5-7 and should not require adjustment).

• Note:* If you choose to use Pro Polymer, be aware that the gel may not thicken properly or may become thin due to the presence of Ammonium Lactate.

Additional Note

This formula contains a variety of beneficial ingredients, which might result in a slightly sticky feel for some skin types. However, for dry skin, this texture might be comfortable and appropriate. Stickiness is subjective and depends on personal preference.
