Ever wonder the science behind your cleanser? Well, wait no longer! Our team has some major insight to how your cleanser works and even recommended cleansers for each skin type! Don’t miss out and keep on reading!
Why use a cleanser?
Cleansers are essential for removing all that dirt, oil, sweat and bacteria building up on your skin. Cleansers can clean by interacting with proteins and lipids of your skin and skin barrier. They can do this thanks to a primary active ingredient- surfactants!
What are they?
We’ve talked about these interesting active agents before. Surfactants are surface active agents with two parts: A water-loving head and an oil-loving tail. Also known as amphiphilic molecules! These agents are quite strong with removing impurities, dirt and oil from your skin.
Surfactants can determine the degree of cleanliness (and harshness) in a cleanser. And their ability to clean depends on the size and charge, along with its micelle formation. When the concentration of the formula reaches a high enough level, known as the critical micelle concentration, the mild surfactants form micelles.
Surfactant and the skin barrier
If you’re not careful, surfactants could cause your skin barrier some damage. This is because surfactants can interact with the protein and lipids in your skin barrier and mess with your skin’s natural function. Ultimately, causing transepidermal water loss, dryness, irritation and inflammation!
Types of surfactants
Based on how charged and big surfactants are, they can fit into one of these four categories! We’re listing them from the most to least harsh on your skin.
1.Most harsh– Anionic surfactants: They tend to foam well, but at the cost of a high pH level which can irritate your skin. Some examples include sodium lauryl sulfate and alkyl ether sulfate.
2.Cationic surfactants: These guys are antimicrobial -a plus- but foam rather poorly. This kind can be heavily irritating for the skin. Some examples of this type are chlorhexidine and benzalkonium chlorid.
3.Amphoteric surfactants: Much less irritating, but not great for foaming. Sodium lauroyl isthionate, cocoamidopropyl betain and cocamphoacetate are a few examples.
4.Least harsh- Non-ionic surfactants: This category is the least irritating and commonly used in makeup remover. On the downside they can be a bit pricy. Alkyl polyglucosides and lauryl glucoside are part of this group!
Types of cleansers
Cleansing is all about removing impurities and restoring a natural pH balance. Many traditional cleansers have a stronger formula of surfactants and therefore higher pH! Luckily with today’s technology, there are many new synthetic detergent, meaning non-soap cleansers, that are gentle and have a lower pH. Just to remind everyone, a healthy pH level sits between 5 and 5.5. Let’s take a look at some different types of cleansers:
