Have you seen that latest DOVE TV commerical where two women were standing side by side showered, one with Dove while the other with an unbranded soap. Then under some heated light they show the woman who showered with ordinary soap having residue all over her body. The Dove woman is perfectly clean. You will find some critics that think that the Dove ad is quite misleading.
The question is can your soap be leaving something behind? And if does leave anything, so what? It doesn’t seem to be a big deal to have some soapy residue left behind until I attended a Dove event that simulates the Dove commercial. There is a scientific explanation to soap residue and the effects on our skin.
Media was provided with two sets of soap. The Blue dot indicates the Dove Brand while the white dot is just any commercial brand of soap. I did the test myself.
We were told to mix the grated soap to the beaker and mix it thoroughly for 2 minutes .
The plastic is supposed to simulate the skin and show how residue is still retained in the water. The unbranded soap showed residue on the plastic while the blue dotted plastic was clear.
An independent study was conducted and published to shed light on different surfactant-induced skin irritations. The analysis found that there is a significant interaction between surfactants (or cleansing agents) in soap, the minerals in water, and our skin. The authors of the study were able to statistically substantiate that soap rinsed off with hard water leaves residue on the skin that may cause irritations and inflammations.
Using the Infrared Spectroscopy Technique (IR), the study showed that residue is formed when soap molecules interact with the calcium in hard water. This calcium-soap mixture forms a gummy, insoluble deposit known as soap scum, which contains dirt and other materials identical to that left on bath tubs. This residue, though invisible to the naked eye, stays on the skin and tends to build up over time. As the residue accumulates, it becomes a major cause of itching and other skin irritations.
Unilever, the manufacturers of Dove â€“ conducted its own study using both the Infrared Spectroscopy Technique and a controlled forearm wash study using litmus paper. A change in the color of the litmus paper indicated the presence of residue. This study confirmed earlier findings that soap-based cleansers indeed deposit residue on the skin because the areas applied with it turned green, while the areas applied with Dove showed no significant color change.
Just how much residue is deposited on the skin after a bath? The latest Dove television ad visually depicts the actual amount through an artistic dramatization of what soap residue would look like on the skin, if we could see it. The commercial shows us a scientifically-corroborated visualization of how much residue is left on our skin by soap-based cleansers.
No Residue Means a Completely Clean Bath
Because Dove is a non-soap formulation, this cleanser is not sensitive to calcium and does not bind with calcium ions to produce residue. With its neutral pH, Dove has no affinity to calcium, and does not form any chemical bonds with it. This means a truly clean bath, with almost no residue of any kind left on the skin, a major reason why Dove causes almost no skin irritations.
Aside from this patented cleansing technology, another reason for Doveâ€™s skin-friendly wash is its strong moisturizing properties. It has been well-established that 25% of the Dove bar consists of a spreadable moisturizer that leaves skin smooth – the way clean skin should feel.
Because Dove leaves skin feeling soft and moisturized – as opposed to the dry, tight skin feel left by soap – more consumers felt cleaner and better after washing with Dove.
Qualibetâ€™s Pinky Tobiano: Putting Dove to the test
To further strengthen its claim, Dove partnered with an authority that has built a reputation on her advocacy, which is to ensure quality standards on food, water, and the basic aspects of life. Pinky Tobiano, CEO and founder of Qualibet Testing Services, was invited to validate the Unilever test. â€œWe did our own testing of Dove versus ordinary soap at the Qualibet laboratories, and came up with the same results,â€ says Pinky. â€œThat compared to ordinary soaps, Dove leaves your skin feeling softer and smoother. And more importantly, Dove does not leave any unnecessary residue on the skin.â€
So itâ€™s not just empty claims: scientific evidence supports the fact that Dove is indeed better than soap because it gives a better clean and promotes overall skin health.
