A concentrate of innovation for your formulations
EstoLight, ready-to-use multifunctional ingredients for your formulations:
→ very easy to use, facilitates the work of formulators.
→ improves pigment dispersion for homogeneous textures.
→ increases solar protection
→ suitable for natural cosmetics with a naturalness index > 99%.
→ compatible with advanced applications such as sunscreens and eco-responsible skincare.
EstoLight are biosourced polymers derived from vegetable oils, patented by ITERG. These naturally-derived products effectively disperse mineral fillers (pigments, pearlescents, colorants, glitter, particles), while ensuring uniform blending and good sensoriality.
This makes them an excellent choice for high-performance, environmentally-friendly cosmetics.
Key performances and benefits
Easy to install
- EstoLight -1E is liquid and non-crystallizing (100% amorphous)
- Easy to use with simple pumping
- Soluble in vegetable oils and oily derivatives
Improved dispersion and homogeneity
- Enables efficient dispersion of concentrated pigment bases even under low shearing conditions
- 3 to 5% of additive in pigment bases (50% pigment, qsp caprilic/capric triglyceride).
- EstoLight -1E makes it possible to obtain more fluid formulations than market references.
Contributes to sun protection
- EstoLight -1E increases sun protection: > up to +75% in sunscreen formulations with organic filters: EHT, DHHB, BEMT
> up to +28% in sunscreen formulations with mineral filters - Maintains SPF after immersion
Improved stability and sensoriality
- Natural thickener for structuring and stabilizing oils and esters
- Promotes a pleasant, soft, easy-to-apply texture
A commitment to naturalness and eco-responsibility
- Biosourced polymer derived from castor oil
- Biodegradable
Technical assessments
Studies conducted: the proven performance of EstoLight-1E in terms of dispersion,
stability, and formulation quality
Studies conducted (microscopy, dispersion in fat phase, LUMiFuge tests, pigmented emulsions) clearly demonstrate that EstoLight-1E improves dispersion and slows pigment sedimentation, even under accelerated stress conditions.
1. Unmilled pigments: significantly improved dispersion
Observations show that:
-
without EstoLight-1E, large pigment aggregates are present,
-
With EstoLight-1E, unground pigments are much better dispersed.
-
Under centrifugation, the sedimentation rate decreases significantly.
👉 EstoLight-1E enables finer and more uniform dispersion, even on difficult pigments.
2. Fat phase: significantly slower sedimentation
Sedimentation rates measured at LUMiFuge consistently show:
-
a slower descent of pigments in the presence of EstoLight-1E,
-
dispersions that remain visually more homogeneous,
-
less aggregation observed after centrifugation.
👉 EstoLight-1E significantly improves pigment suspension stability.
3. Iron oxides: better particle retention in the fatty phase
Tests on red, yellow, and black oxides show:
-
slower sedimentation with EstoLight-1E,
-
more even dispersion and fewer clumps,
-
in some cases, more uniform crystallization of fats.
👉 EstoLight-1E optimizes the dispersion of mineral pigments and improves their behavior under stress.
4. Colorants: improved suspension and better hold
The results show:
-
slower sedimentation with EstoLight-1E,
-
a more uniform color,
-
emulsions that show enhanced stability according to tests.
👉 Even with very fine pigments, EstoLight-1E improves dispersion stability.
In summary, these studies demonstrate that:
The tests carried out clearly show that EstoLight-1E:
-
improves pigment dispersion (including unground pigments),
-
reduces aggregates,
-
slows down sedimentation in the fat phase,
-
promotes more homogeneous dispersions,
-
allows for better color and particle retention,
-
provides a recognized benefit on pigments, iron oxides, and dyes.
Studies show that EstoLight-1E provides an innovative solution to the challenges of pigment dispersion and stability, paving the way for more effective and controlled formulations.
