It’s a 10 Silk Express Miracle Silk Shampoo

As a cleansing agent, sodium lauryl sulfoacetate helps reduce the surface tension of dirt, oil, and other pollutants so they can be rinsed away easily.

Cosmetic Ingredient Review found this ingredient to irritate the eyes and skin in concentrations of 0.18% and 0.7%.

Being created from coconut oil means Cocamidopropyl Betaine is hydrating for the skin.

While Cocamidopropyl Betaine was believed to be an allergen, a study from 2012 disproved this. It found two compounds in unpure Cocamidopropyl Betaine to be the irritants: aminoamide and 3-dimethylaminopropylamine. High-grade and pure Cocamidopropyl Betaine did not induce allergic reactions during this study.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

Because it has a neutral charge, it is compatible with a wide range of ingredients and stays stable across a broad pH range/water hardiness conditions.

Patch testing has shown it to have the lowest irritation potential among common cleansing surfactants (like SLS).

Typical use levels range from 5-20% in rinse-off cleansers.

One thing worth knowing: The American Contact Dermatitis Society named the parent family, alkyl glucosides, "Allergen of the Year" in 2017. The prevalence of allergy is pretty low but be sure to patch test if you've reacted to "gentle" or sulfate-free cleansers before.

This ingredient is fungal acne safe because the fatty alcohol portion of this ingredient is below the C11-24 chain length that Malassezia can metabolize.

It is derived from stearic acid, a natural fatty acid commonly found in vegetable oils and animal fats.

Glycol Distearate isn't fungal acne safe.

As a humectant, it helps draw moisture from the air to your skin. This helps your skin stay hydrated.

Due to the origins of this ingredient, it is not vegan. Silk is an animal product from silkworms.

Depending on the source, this ingredient can be considered cruelty-free. It is created from left-over cocoons of silkworms. We recommend reaching out to the brand if you have questions about where their hydrolyzed silk comes from.

The Cosmetic Ingredient Review Panel has assessed the available safety data and found it to safe in cosmetics.

The comedogenic rating of 2/5 means it is low-to-moderate risk of pore clogging; please remember comedogenic ratings cannot predict how the overall formula will behave on skin.

Because its dominant fatty acids (palmitic and oleic acid) fall within the C11-24 range that Malassezia can use as a growth substrate, this ingredient may not be fungal acne safe.

D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.

Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):

Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.

This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.

Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

This ingredient is also referred to as pro-vitamin B5.

The CIR Expert Panel has confirmed this ingredient to be nontoxic and clinical studies show no sensitization at cosmetic use concentrations.

True allergic reactions are quite rare: a 15-year retrospective study of 6,751 patients found only 0.31% had a positive reaction (and less than half were considered clinically relevant).

It seemed that when sensitization does occur, it's most commonly linked to topical medication (like corticosteroids) and not cosmetics. Allergic contact dermatitis also appears largely limited to individuals with underlying skin conditions.

Overall, propylene glycol is a well-studied ingredient that most people can tolerate without issue.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

The fatty acids found in sunflower seeds include (from highest amount to least): linoleic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid.

These fatty acids hydrate your skin. Emollients create a film on the skin to prevent moisture from escaping.

Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.

Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.

This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.

Just know very high concentrations (>40%) can feel tacky in low humidity.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Lauryl alcohol pulls triple duty:

Because lauryl alcohol falls within the C11 - C24 carbon chain range that the Malassezia yeast (fungal acne) can metabolize, this ingredient may not be fungal acne safe.

Due to the large molecule size, this ingredient is unlikely to penetrate skin.

However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products.

Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH.

In skincare formulas, citric acid can:

While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants.

Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations.

While Benzyl Salicylate has been associated with contact dermatitis and allergies, emerging studies show it may not be caused by this ingredient alone.

However, this ingredient is often used with fragrances and other components that may cause allergies. It is still listed as a known allergen in the EU. We recommend speaking with a professional if you have concerns.

Another study from 2021 shows Benzyl Salicylate may have anti-inflammatory properties.

This ingredient has a scent that is floral, spicy tropical, and citrus-like.

This ingredient is safe in cosmetics when formulated to be non-sensitizing and concentrations must not exceed 7.5 ppm in leave-on products / 15 ppm in rinse-off products.

Unfortunately, this ingredient has a well-documented sensitization story. Studies spanning several decades have shown this ingredient + MI to cause skin irritation and allergies.

The use of this ingredient varies around the world:

This just means this ingredient is most likely non-sensitizing in rinse-off products unless you've been diagnosed with a contact allergy to isothiazolinones.

Since then, numerous studies have shown this ingredient to cause contact dermatitis, or skin irritation.

The use of this ingredient varies around the world:
