Cien Collagen & Biotin ShampooIngredients explained
Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product.
It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water.
Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.
One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time.
A versatile and biodegradable cleansing agent with high cleaning power and strong foaming properties. Unfortunately, these two properties for a surfactant usually mean that it is harsh on the skin, which is the case here as well.
Sodium chloride is the fancy name of salt. Normal, everyday table salt.
If (similar to us) you are in the weird habit of reading the label on your shower gel while taking a shower, you might have noticed that sodium chloride is almost always on the ingredient list. The reason for this is that salt acts as a fantastic thickener in cleansing formulas created with ionic cleansing agents (aka surfactants) such as Sodium Laureth Sulfate. A couple of percents (typically 1-3%) turns a runny surfactant solution into a nice gel texture.
If you are into chemistry (if not, we understand, just skip this paragraph), the reason is that electrolytes (you know, the Na+ and Cl- ions) screen the electrostatic repulsion between the head groups of ionic surfactants and thus support the formation of long shaped micelles (instead of spherical ones) that entangle like spaghetti, and viola, a gel is formed. However, too much of it causes the phenomenon called "salting out", and the surfactant solution goes runny again.
Other than that, salt also works as an emulsion stabilizer in water-in-oil emulsions, that is when water droplets are dispersed in the outer oil (or silicone) phase. And last but not least, when salt is right at the first spot of the ingredient list (and is not dissolved), the product is usually a body scrub where salt is the physical exfoliating agent.
A thickening and foam-boasting co-surfactant with amphoteric structure meaning that its head contains both a positively and a negatively charged part (surfactants are most commonly anionic meaning their head has a negative charge). It's very mild and gentle, comes from coconut oil and is readily biodegradable.
A cleansing agent that's claimed to be so gentle on the skin that it hardly impacts the skin barrier. It also gives a rich, creamy foam, it's based on vegetable fatty acids and is readily biodegradable.
It's an especially important and popular ingredient in "syndet bars" (or soapless soaps). Dr. Leslie Baumann says in her great Cosmetic Dermatology book that thanks to the unique molecular characteristic of Sodium Cocoyl Isethionate, it "has defined a new dimension in the mildness of cleansing bars".
Super common ingredient in all kinds of cleansing products: face and body washes, shampoos and foam baths.
Number one reason for its popularity has to do with bubbles. Everyone loves bubbles. And cocamidopropyl betaine is great at stabilizing them.
The other reason is that it’s mild and works very well combined with other cleansing agents and surfactants. The art of cleansing is usually to balance between properly cleansing but not over-cleansing and cocamidopropyl betaine is helpful in pulling off this balance right.
Oh, and one more nice thing: even though it’s synthetic it’s highly biodegradable.

Probably the most common silicone of all. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thick liquid.
As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Also, works well to fill in fine lines and wrinkles and give skin a plump look (of course that is only temporary, but still, it's nice). There are also scar treatment gels out there using dimethicone as their base ingredient. It helps to soften scars and increase their elasticity.
As for hair care, it is a non-volatile silicone meaning that it stays on the hair rather than evaporates from it and smoothes the hair like no other thing. Depending on your hair type, it can be a bit difficult to wash out and might cause some build-up (btw, this is not true to all silicones, only the non-volatile types).
Exactly what it sounds: nice smelling stuff put into cosmetic products so that the end product also smells nice. Fragrance in the US and parfum in the EU is a generic term on the ingredient list that is made up of 30 to 50 chemicals on average (but it can have as much as 200 components!).
If you are someone who likes to know what you put on your face then fragrance is not your best friend - there's no way to know what’s really in it.
Also, if your skin is sensitive, fragrance is again not your best friend. It’s the number one cause of contact allergy to cosmetics. It’s definitely a smart thing to avoid with sensitive skin (and fragrance of any type - natural is just as allergic as synthetic, if not worse!).
A cellulose derived polymer (a big molecule that consists of many parts) that can help to thicken up products, form a nice film on the skin or hair and is considered to be an excellent hair conditioner.
Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA.
So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.
There is also some research showing that citric acid with regular use (think three months and 20% concentration) can help sun-damaged skin, increase skin thickness and some nice hydrating things called glycosaminoglycans in the skin.
But according to a comparative study done in 1995, citric acid has less skin improving magic properties than glycolic or lactic acid. Probably that’s why citric acid is usually not used as an exfoliant but more as a helper ingredient in small amounts to adjust the pH of a formulation.

It's one of those things that help your cosmetics not to go wrong too soon, aka a preservative. Its strong point is being effective against yeasts and molds, and as a nice bonus seems to be non-comedogenic as well.
It is safe in concentrations of less than 0.1% but is acutely toxic when inhaled, so it's not the proper preservative choice for aerosol formulas like hairsprays. Used at 0.1%, Iodopropynyl Butylcarbamate has an extremely low rate of skin-irritation when applied directly for 24 hours (around 0.1% of 4,883 participants) and after 48 hours that figure was 0.5%, so it counts as mild and safe unless your skin is super-duper sensitive.
- It's a helper ingredient that improves the freeze-thaw stability of products
- It's also a solvent, humectant and to some extent a penetration enhancer
- It has a bad reputation among natural cosmetics advocates but cosmetic scientists and toxicology experts do not agree (read more in the geeky details section)

A white waxy solid that helps water and oil to mix nicely together (emulsifier). It is derived from the fatty alcohol lauryl alcohol by ethoxylating it and thus making the molecule a lot more water-soluble. In fact, Laureth-23 is mostly water-soluble acting as a solubilizer for dissolving small amounts of oily things into water-based formulas.
The chemically chopped up version of the big protein molecule, collagen. It is often derived from fish or bovine sources and works as a nice moisturizer and humectant that helps the skin to hold onto water.
To understand a bit more what Hydrolyzed Collagen is, you have to know that proteins are large chains of amino acids connected with so-called peptide bonds. These bonds can be broken up when a water molecule is added and the resulting thing is a mix of shorter length amino acids, also called peptides. So Hydrolyzed Collagen is not really collagen, it is rather an undefined and varying mix of largish peptides. Based on a manufacturer's data, the whole, soluble collagen has an average molecular weight of 300 000 Da, while this chopped up mixture has an average MW of 12 000 Da (still pretty big).
The main thing of these largish peptides is to act as water-binding agents, and to make the skin nice and smooth (aka emollient). Hydrolyzed Collagen is also often used in cleansers as it can make harsh surfactants milder and in hair conditioners as it improves the flexibility and manageability of hair.

As you may guess, if something is only recommended in products that you rinse off (cleansers and shampoos), then it’s probably not the best ingredient for the skin.
Methylisothiazolinone (MI) is a preservative that' super efficient against bacteria at surprisingly low concentrations. The problem with it though is that it can also sensitize and irritate the skin quite easily when it comes in leave-on formulas.
Currently, some countries are considering to ban it entirely (like Denmark) and the permitted use level is very low (under 0.01%). Luckily there are plenty of products on the market with other preservative options so if you are a better safe than sorry type it's probably best to avoid it.
A chemically chopped up version of wheat protein that consists mainly of amino acids (the building blocks), peptides (a couple of amino acids together), and proteins (lots of amino acids together).
It has moisturizing and film-forming properties and might be able to counteract the irritating effects of cleansing agents in cleansers and shampoos. It can also condition and repair damaged hair leaving it soft, silky and smooth.
This totally unpronounceable ingredient (let’s take a shortcut: MCI) is a super effective preservative with both antibacterial and antifungal effects that works at very low concentrations.
The bad news with it though is that it can sensitize the skin easily (it’s a so-called non-fragrance allergen). It’s not permitted to be used alone, but only with its BFF, methylisothiazolinone (MI), another icky preservative. Together they have a broad spectrum antimicrobial effect but are permitted to be used only in rinse-off products (under 0.0015%).
A super common synthetic colorant that adds a purple-red color - similar to red beet - to a product.
Also called vitamin H, biotin is the main component of many enzymes in our body. A nice ingredient to take as a supplement for stronger nails and hair. When you do not take it as a supplement its effects are a bit more questionable but according to manufacturer info it can smooth the skin and strengthen the hair.
