What is the recommended pH target for DIY Intense Moisturising Cream for Mature Skin (CoQ10 + Niacinamide + Hyaluronic Acid)?

For stable cosmetic performance, the ideal pH is between 5.0 and 5.5 for barrier and brightening serums, or 5.5 to 6.5 for hair vitality and rinse-off washes. Always test and adjust using a calibrated digital pH meter or high-accuracy test strips.

Which broad-spectrum preservative is recommended for this water-containing recipe?

Any aqueous cosmetic formulation requires broad-spectrum preservation against bacteria, yeast, and mold. We recommend 0.5%–1.0% Phenoxyethanol + Ethylhexylglycerin (Ases Preserve PHEHG) or Liquid Germall Plus, incorporated during the cool-down phase below 45°C.

What is the expected shelf life of this finished formulation?

When prepared under sanitized studio conditions with distilled water and an approved broad-spectrum preservative at proper pH, the typical shelf life is 12 to 18 months stored in airtight pump bottles below 25°C.

Can this formulation recipe be scaled up for commercial batch manufacturing?

Yes. All formulation percentages are calibrated to 100% batch weight. To scale from a 100g test sample to a 10kg or 50kg production run, multiply each ingredient weight proportionally while maintaining temperature controls and high-shear blending.

How to Make Intense Moisturising Cream for Mature Skin (Step-by-Step)

1. Prepare Phase A

Add Grapeseed Oil, CoQ10, Olivem 1000, and Cetyl Alcohol into a beaker.

2. Prepare Phase C (Hyaluronic Acid Mixture)

Mix Hyaluronic Acid into glycerin to prevent clumping.
Slowly add distilled water while stirring until fully dissolved.

3. Heat Phase A and Phase C

Heat both beakers in a double boiler to ~40°C.
Do not exceed 45°C as CoQ10 and HA are temperature-sensitive.

4. Combine Oil & Water Phases

Add Rosehip Oil (Phase B) into the melted oil phase.
Pour the hot water phase into the oil phase.
Blend until a creamy emulsion forms.

5. Cool Down

Once the cream reaches room temperature, add:

Niacinamide
Green Tea Extract
Geogard ECT
Fragrance (optional)

Stir well.

6. Adjust pH to 5.5

This pH ensures:

Niacinamide remains stable
Geogard ECT works effectively
Skin-friendly, gentle formulation

7. Transfer to Jar

Pour your finished cream into a sterilised cream jar. Let it set for a few hours for best texture.

Ideal pH, Shelf Life & Storage
