What are mechanisms of action of Triclosan and Povidone?

NNADVOKAT [17]

Answer:

Povidone: its action is produced by oxidation and inactivation of cellular components.

Triclosan: is absorbed by intact skin which determines its persistence and its speed of action is intermediate.

Explanation:

Povidona:

- It presents the same mechanism of action and spectrum of iodine.

- It is a water-soluble compound that results from the combination of iodine and polyvinylpyrrolidone, which improves the solubility of iodine and allows its gradual release into tissues. This effect determines less skin irritation and greater product availability over time.

- The term "available iodine" refers to the amount of iodine available as a reservoir and that of free iodine to the percentage in solution in working condition, that is, a 10% povidone iodine solution, contains 1% of available iodine and the iodine concentration Free is 1 to 2 parts of a million that remains until the available iodine is depleted. This product advantage is lost when diluted in water, since in these circumstances it behaves as an aqueous solution of iodine.

- Its activity can be diminished by the presence of blood or other organic matter.

- The concentrations commonly used as a surgical scrubber are 7.5% and 8% and in the one used for cures it is 10%.

- In relation to tincture of iodine or lugol, it presents less dermal irritation. They should be used with caution in newborns and burned

- Its antiseptic action is classified between high level and intermediate level. They are lethal in minutes for bacteria, fungi, viruses, protozoa, amoeba cysts and spores. However, in front of dry spores it requires a longer exposure time (hours).

- Iodized antiseptics have the advantage of being cheap.

Triclosan:

- It is a relatively new phenolic derivative that acts causing damage to the cell wall of microorganisms. It is broad-spectrum bacterial, better for Gram + and there is little information about its activity in viruses.

- <em>It is absorbed by intact skin which determines its persistence and its speed of action is intermediate. </em>

- No allergenic or mutagenic effect has been demonstrated in short periods of use.

- Its activity is minimally affected by organic matter.

- The concentrations of usual use are between 0.3% and 2%.

- It is mainly indicated for clinical handwashing where it is used in 1% breads and in 0.5% liquid preparations.

What is the your groundbreaking idea for a razor or hair removal product that awakens your senses?

Hatshy [7]

Answer:

hope it helps you

Explanation:

Traditionally, shaving and hair removal brands provide mainly functional benefits: they get the job done, but they don’t deliver an enriching, self-care experience. Their products aren’t going to uplift you or make you feel calm and relaxed. Instead, they offer mundane experiences and boring designs and scents.

As a leading personal care brand, we are looking for razor and shave preparation ideas that will make shaving enjoyable, that are experiential, and that stimulate the senses (olfactory, tactile, vision, etc.). We are looking for creative solutions that will appeal to those who love variety, who enjoy exploring new things, and who value enriching experiences. Personal care should give us a chance to reground ourselves, awaken our senses, and feel better in our day-to-day.

We are interested in groundbreaking ideas for wet-shave devices (e.g. razors) and/or packaging that will awaken your senses without compromising the effectiveness or durability of the products.

Your idea could improve the sensory shaving experience at any level. Primarily, we are looking for ideas that relate to razors, but we are also open to shave preparation (pre, during, post shaving) as well as packaging. In proposing your idea(s), please consider the following:

Be creative! Feel free to go beyond scents / olfactory experience.

Bring ideas for razors, shave preparation, pre-shaving and post-shaving.

Women should be the target demographic for your product idea. Please be sure your idea has feminine appeal.

Your idea should be feasible for high-volume production (think about processing conditions and high speed manufacturing).

Your product idea should be able to survive in the typical “bathroom” / usage environment of a razor. Think of the shower, where there is high humidity, exposure to chemicals from other products, etc.

Please include any references or background information related to your proposed material sources. We want to understand what inspired your idea and review any relevant sources that support it!
