DOWSIL(TM) HMW 2220 Non-Ionic Emulsion

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.

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.

Resistance to Breakage on Heat-Damaged Hair

Hair strength/resistance to breakage is measured by the number of broken fibers after 10,000 strokes.

Using Leave-in Conditioners (CPF 02196)

• Treatment: 2% active silicone level, 0.1 g/g hair.
• Hair Type: Slightly bleached.
• At 80% weight loss, tresses are visually dry

All products are statistically different from the control at ≥95% confidence level.

Results: Up to 25% faster drying was achieved using silicones from Dow.

This high-foaming facial cleanser cleans the face, absorbs sebum and continues to significantly reduce sebum for up to two hours. In sensory testing, this cleanser shows improved foam quality and quantity, ease of rinse and smoothness compared with a commercial benchmark.
