Solution for Thick Niacinamide Essence

You are experiencing a common issue when formulating with gelling agents like Carbomer – they can easily create a thick gel texture. To achieve a lighter, essence-like texture similar to Hada Labo, as discussed in the previous replies, you can indeed replace or adjust the gelling agent.

Based on the information and product descriptions, Hyaluronic Acid (Standard Molecule) is a suitable ingredient to use instead of Carbomer to get that desired texture. Hyaluronic Acid (Standard Molecule) forms a light gel and provides hydration to the outer layer of the skin, which is characteristic of an essence or light serum.

To make a 2000g batch with a texture similar to Hada Labo, a concentration of Hyaluronic Acid (Standard Molecule) between 0.25% and 0.5% is recommended. Let's calculate the amount needed for a 2000g batch at a starting concentration of 0.3%:

Amount of Hyaluronic Acid (Standard Molecule) = 2000 g * (0.3 / 100) = 6 grams

You can adjust the percentage slightly within the 0.25% - 0.5% range to find the exact texture you prefer. Formulation often requires testing and minor adjustments.

Remember to properly dissolve the Hyaluronic Acid (Standard Molecule) powder in the water phase. The product description suggests adding the powder to water and either shaking vigorously and refrigerating for several hours until dissolved, or using a high-speed blender.

Also, ensure you include a suitable preservative in your formula, as solutions containing water and active ingredients like Niacinamide (such as Safe-B3 or Extreme-B3) and Hyaluronic Acid are susceptible to microbial growth.

By replacing Carbomer with Hyaluronic Acid (Standard Molecule) at an appropriate concentration, you should be able to achieve the lighter essence texture you are looking for.
