Sensory Data
DOWSIL™ HMW 2220 Non-Ionic Emulsion generates foam faster than the control and gives a more creamy foam. Wet skin is more slippery and after drying, skin is smoother and more supple.Test Results
Shower Gel Deposition
- Spectrum of neat skin of volar forearm is taken
- The test zone is washed with the shower gel
- A spectrum is taken and the relative quantity of silicone is measured
Sensory Profile for Shower Gel Containing DOWSIL™ HMW 2220 Non-Ionic Emulsion Versus Control
Deposition Data
The presence of silicone can be detected on the skin after the use of the shower gel.
Deposition of DOWSIL™ HMW 2220 Non-Ionic Emulsion on Skin
Water in Silicone Creams
A water-in-silicone cream containing 2.3% of DOWSIL™ HMW 2220 Non-Ionic Emulsion has been found to have a significantly different feel (99% confidence level) from the same cream without the silicone. In addition, the sensory threshold has been found to be very low to provide expected benefits.

- Sun Care Applications
- Recommended Applications
DOWSIL™ HMW 2220 Non-Ionic Emulsion has been designed as a unique way of incorporating high viscosity polymer (> 120 x 106 mm²/s) into water-based systems.
This product can be used in skin care and body wash applications including:
- Skin creams
- Facial cleansers
- Shower gels
This product can be used in hair care applications including:
- Shampoos
- Rinse-off and leave-in conditioners
- Styling products
- Usage
DOWSIL™ HMW 2220 Non-Ionic Emulsion is best added at temperatures below 50°C (122°F) to minimize risk of emulsion separation. The recommended addition level is 2 to 5% silicone active.
How to Apply
- Shower Gels - DOWSIL™ HMW 2220 Non-Ionic Emulsion should be added at the end of the process after the final water addition.
- Skin Creams - DOWSIL™ HMW 2220 Non-Ionic Emulsion should be added at the end after the preparation of the cream base. Avoiding high shear mixing is important to prevent the emulsion breaking.

Technical Details & Test Data
- Skin Tightening with Comfort
A sensory panel evaluated DOWSIL(TM) MQ-1640 Flake Resin and DOWSIL(TM) FA 4002 ID Silicone Acrylate at 3% use levels in hydrogel formulations. A paired comparison test was used to assess each silicone. In both cases, the control offered instant tightening, but no lasting tightening sensation. In their respective formulations, the silicone materials provided instant as well as lasting tightening. Panelists also noted low tackiness and residue for silicone acrylate solution, along with an invisible film on the skin.
The addition of a small amount of DOWSIL(TM) HMW 2220 NonIonic Emulsion significantly improved the sensory profile with no impact on the skin tightening performance in combination with both silicone acrylates and resin film-formers.(Figure 1)
The tightening effect noted in sensory evaluations was confirmed with a Cutometer.
In Figure 2, the combination of silicone acrylate or silicone flake resin with the high molecular weight non-ionic emulsion shows a decrease in R0, which reflects an increase in skin firmness, then a tightening benefit.
As a complement to the series of laboratory tests, an in-use test was carried out with the help of 57 Dow employees who served as panelists. The female and male participants ranged in age from 20 to 70 and had typical Caucasian skin types. Two hydrogels were tested: one containing DOWSIL(TM) MQ-1640 Flake Resin (3%) and DOWSIL(TM) EP-9801 Hydro Cosmetic Powder (3%), and the second containing DOWSIL(TM) FA 4002 ID Silicone Acrylate (3%) and DOWSIL(TM) HMW 2220 Non-Ionic Emulsion (0.3%).
For both hydrogels, panelists confirmed the following findings of
the earlier evaluations:- They provided instant and lasting tightening.
- The formulations were comfortable to wear, with a tightening sensation on skin.
- There was a positive impact on wrinkle attenuation.
- The products left an invisible film on skin.

- Age-Defying Hair Repair
Erase the Signs of Damage and Protect Hair Color
Heat-Damaged Hair Colored Hair
Restore the Surface of Heat-damaged Hair to a Healthy State
Healthy Hair - Water droplet on healthy hair remains intact, indicating hydrophobic nature and natural protection.
Heat-damaged Hair – No Repair - Damaged hair becomes hydrophilic, indicating loss of protection. After shampoo and rinse-off conditioner without silicone, water droplet spreads instantaneously, showing no repair.
Heat-damaged Hair - Repaired - Shampoo + rinse-off conditioner containing a DOWSIL™ silicone helps restore the hair’s hydrophobicity and natural protection capability
Shine/Luster on Color-treated Hair
Hair shine is measured using a light-scattering image analysis system.
