Sodium Lauroyl Glutamate is the sodium salt from the lauric acid of glutamic acid.
It is a surfactant and helps cleanse the skin. Surfactants gather oil, dirt, and other pollutants from your skin so they may be washed away easily.
Potassium Cocoyl Glycinate is an amino acid-based surfactant and cleaning agent. This ingredient can be derived from animals or plants. It may also be synthetically created from fatty acids of the coconut and glycine.
Potassium Cocoyl Glycinate is a gentle surfactant. Surfactants help gather the dirt, oil, and other pollutants from your skin to be rinsed away. It is a mild cleanser and naturally produces foam.
Kaolin is a clay. It is used for oil control and to help minimize pores. Like other clays, kaolin has the ability to absorb excess sebum or oil. This can help clean out pores and mattify the skin.
Some types of kaolin may have exfoliating properties. When water is added to kaolin, it becomes a paste with small abrasive particles.
Most kaolin is a white color, but may be pink/orange/red depending on where it comes from.
The name 'kaolin' comes from a Chinese village named 'Gaoling'. Kaolin clay comes from rocks rich in kaolinite. Kaolinite, the mineral, has a silicate layered structure. Kaolinite is formed from chemical weathering of aluminum siilicate minerals.
Besides skincare, kaolin is commonly used to make glossy paper, in ceramics, toothpaste, and as medicine to soothe stomach issues.

Cellulose is the main component of plant cell walls. It is used as an emulsifier, absorbent, and texture enhancer.

Aluminum Starch Octenylsuccinate is a synthetic powder used as an absorbent, thickener, and anti-caking agent.
As an absorbent, it is great at mattifying skin by soaking up the oil. This is why you'll find it in a range of products from makeup to moisturizers.
This ingredient is considered a modified starch. Starch can also be found naturally in plants.
One study from 1991 found that 5% of this ingredient enhanced titanium dioxide SPF by as much as 40%. The study found 1% titanium dioxide had a 5.6 SPF and adding 5% of aluminum starch octenylsuccinate boosted it to an SPF of 8.1
Although “aluminum” in an ingredient name can raise red flags for some consumers, the form and usage context matter significantly. For typical topical applications, there is no substantial evidence of health risks - such as cancer, neurotoxicity, or systemic “aluminum overload.”

It is a white powder that can be used to add bulk and color to products by binding to oil ingredients.
Tartaric acid is an AHA with exfoliating and antioxidant properties. It is found in many fruits, such as tamarind, grapes, bananas, and avocados.

This ingredient is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.
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.
