Creme And Tonic Balsa Body Wash

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.

Rinse-off concentrations typically range from 2-25%.

The finished product sits at a fairly high pH (~9-11) because it's a true soap. This just means it can feel drying or slightly stripping if a formula isn't balance with emollients.

Allergy and irritation risk is low as this ingredient was found to be an irritant in less than 1% of subjects (2 of these subjects had active psoriasis and 3 had active eczema).

Fungal acne: The Malassezia yeast feeds on fatty acids in the ~C12-24 range, and Potassium Cocoate is made of exactly those (Lauric C12, Myristic C14, Palmitic C16, Oleic C18:1). Lab studies have shown the yeast can take up Lauric Acid and grows readily on Palmitic Acid. Therefore, this ingredient may not be fungal acne safe.

The Cosmetic Ingredient Review Panel has assessed it in 1983, 2002, and 2005 and found it to be safe in formulations at low concentrations.

SLS is a well-documented skin irritant at higher concentrations or with prolonged exposure. It's actually the gold standard positive control used in dermatological patch testing, meaning doctors use it because they know it will cause a reaction in people.

In one large study of 43,000 patiences tested with 0.25% SLS, about 22% showed some level of reactivity. It increases transepidermal water loss that disrupts your outermost layer of skin.

Face cleansers often pair this ingredient with mild co-surfactants like Cocamidopropyl Betaine to buffer its harshness.

Just so you know, SLS does not trigger true allergic contact dermatitis. This just means it can irritate your skin but doesn't cause your immune system to develop a lasting allergy to it.

Despite internet rumors, SLS is not considered a carcinogen by any major regulatory body.

According to CIR, this ingredient is generally considered safe when used in cosmetics. However, like all surfactants, it can be irritating when used in high amounts of in formulas that aren't well balanced.

Its headline job is hydration.

The star polysaccharide in aloe, acemannan, is a humectant that retains moisture and helps reduce trans-epidermal water loss.

Aloe also has real soothing credentials; it contains anti-inflammatory compounds like bradykinase and C-glucosyl chromone that help calm irritation and redness.

On the repair side, lab work shows that acemannan wakes up your skin's repair cells (fibroblasts), prompting them to multiply and speed up healing.

There's some human data for cosmetic benefit too: a cream containing 10% Aloe Barbadensis leaf extract improved skin hydration and elasticity in a real-use study.

Safety-wise, this ingredient is well-regarded with just one rare downside; there have been some case reports of acute eczema, contact urticaria, and dermatitis in people who applied aloe-derived ingredients topically. Those with a known aloe or Liliaceae sensitivity should patch test.

Typical use levels range widely, from under 1% up to 90%+ depending on the format and the effect you are after.

Here's what the research shows:

In-vitro shows it calms inflammation signals; the most skin-relevant study put a kelp extract on human skin cells and then hit them with inflammatory triggers. The kelp-treated cells produced less of the inflammatory messenger molecules that normally get released.

In a realistic 3D model of skin, the pre-treated tissue held onto its cell-to-cell "seals" better and leaked less water (basically the lab version of a strong vs. weak skin barrier).

Two honest notes: the seal effect only showed up in the 3D model and at higher doses the extract started harming the cells (so more might not be better)

Fucoidan is why kelp gets talked about; it's the sulfated sugar molecule that brands like to name-drop. When four fucoidans were compared, the one from Macrocystis pyrifera was the most active. Just know this was from immune research and not skincare research.

On real people, the numbers look good (with an asterisk). The strongest evidence is all on Macrocystis Pyrifera Ferment inside one company's finished serum and not the plain extract.

Using it twice daily for eight weeks raised skin moisture 16 percent and cut water loss through the skin by 11 percent. A stripping test that repeatedly tapes and peels the skin surface found treated skin held up 30 percent better.

The standout result: half the face was prepped for three weeks and then the whole face got a 70 percent glycolic peel. The prepped side had recovered 71 percent of its barrier versus 23 percent untreated two hours later. A separate review also reported less visible redness and improvement in visible aging measures.

Three asterisk: It's the ferment, not the extract. The kelp isn't necessarily doing all the work since it's the whole formula. And it was funded by The Estée Lauder Companies with several authors on staff.

There's no fixed concentration published for this ingredient but real-world use survey shows this ingredient can be used up to 36%. There's an extra wrinkle for leave-on products since these extracts are usually supplier pre-diluted in water, glycerin, or propanediol.So "5%" on the bottle might mean under 1% for actual kelp solids.

On allergies: kelp is naturally iodine-rich, so people with a known iodine or seafood ingredient sensitivity should patch test.

You'll see algae listed as a 5/5 on a lot of pore-clogging charts and that number doesn't come from anywhere; it's not in the original rabbit-ear studies that most comedogenic ratings trace back to.

The reasoning behind the reputation is that seaweed is high in iodine and iodine can trigger acne-like breakouts when eaten. This traces back to a 1976 letter in Archives of Dermatology describing two women whose breakouts cleared after they stopped taking high-dose kelp supplements orally.

And the reaction of these two women wasn't clogged pores at all: it was an iodine-triggered pustular rash. Later research found normal dietary iodine doesn't meaningfully affect acne either and nobody has shown topical algae delivers enough iodine to matter.

What we do have is dozens of brown and red algae ingredients found to be non-irritating and non-sensitizing, and a handful of studies that found algae compounds may actually help acne.

However, plenty of people do report breaking out from algae-containing products. Skin is individual and it's worth avoiding if yours has reacted to algae before.

The scent of Rose Geranium closely resembles. you guessed it: roses.

Citrus peels are often made up of mainly limonene, a fragrance with a citrus scent. They also contain flavonoids, which have anti-inflammatory properties.

Like all essential oils, this ingredient is a known sensitizer at higher concentrations. This is because this oil also contains known skin-irritating fragrances, limonene and camphor. Limonene and camphor are both known EU allergens.

While patchouli oil holds FDA GRAS ("generally recognized as safe") status, it is typically used at low levels and subject to usage guidelines.

Those with sensitive skin should patch test before using.

Lab studies credit this oil with antioxidant, anti-inflammatory, and antimicrobial activity. Some research even show rosemary compounds calming acne-related inflammation.

The Cosmetic Ingredient Review (CIR) has concluded rosemary-derived ingredients to be safe when formulated to be nonsensitizing.

Since this is a fragrant essential oil, the main concern is for fragrance-sensitive folks.

Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
