Need advice on improving stability and moisturizing performance of my lip care f

Posted by AnnDong on November 2, 2025 at 8:06 pm
Hi everyone,

I’m currently developing a lip care formula with a rich, glossy texture inspired by high-end products like La Mer Lip Balm. I’d love to get your feedback on two main aspects:
1. Improving the <strong data-start=”583″ data-end=”596″>stability of the system (preventing phase separation or graininess).
2. Enhancing the <strong data-start=”675″ data-end=”698″>moisturizing effect and overall comfort on lips (soft, plump, smooth finish).
Here’s my current formula and processing details:

<strong data-start=”813″ data-end=”859″>Phase A – Oil base & silicone phase (80°C)

<ul data-start=”862″ data-end=”1153″>
Caprylic/Capric Triglyceride
Dimer Dilinoleyl Dimer Dilinoleate
Ethylhexyl Polyhydroxystearate
Phenyl Trimethicone
Ethylhexyl Palmitate
Hydrogenated Polyisobutene
Squalane
Polyglyceryl-2 Diisostearate
Helianthus Annuus (Sunflower) Seed Oil Unsaponifiables

<strong data-start=”1155″ data-end=”1173″>Phase B (80°C)

<ul data-start=”1176″ data-end=”1348″>

Silica Dimethyl Silylate: 1%
Shea Butter: 4%
Plandool H
Candelilla Wax: 4.5%
Behenyl Alcohol: 2.7%
Polyglyceryl-3 Diisostearate
Glyceryl Caprylate
Jojoba Esters

<strong data-start=”1350″ data-end=”1368″>Phase C (40°C)

<ul data-start=”1371″ data-end=”1447″>

Tocopheryl Acetate
Tetrahexyldecyl Ascorbate
Ceramide
SWT-7L

<strong data-start=”1449″ data-end=”1467″>Phase D (40°C)

<ul data-start=”1470″ data-end=”1548″>

Nano Resveratrol
Nano Omega-3
Butylene Glycol
Pentylene Glycol

I’m looking for insights on:

<ul data-start=”1581″ data-end=”1956″>

How to <strong data-start=”1590″ data-end=”1612″>optimize the ratio or structure to improve stability (especially with the mix of natural oils, silicones, and butters).
Ways to <strong data-start=”1726″ data-end=”1756″>enhance moisture retention — should I adjust the emollient balance or introduce an occlusive/humectant alternative?
Whether adding a small amount of <strong data-start=”1883″ data-end=”1914″>ester or film-forming agent could improve payoff and lip adherence.

Any suggestions or experiences would be really appreciated!

Thanks in advance 🙏
