1) What are sulfates and are they something I should be avoiding?
Almost all of us have heard about “sulfates” but we are not sure what they really are, why they are used and whether we should be using products containing sulfates. Let’s try and unravel the mystery…
“Sulfates” is the common use term for a group of cleaning ingredients more correctly known as “alkyl sulfates”. Sulfates are the most common cleaning ingredients used in commercial cleaning products, such as laundry and dishwashing detergents and engine degreasers. They are used because they are the lowest cost most powerful cleaning ingredients available.
However sulfates are also the most common cleansing ingredients used in skin and hair care products! No wonder so many people suffer from an itchy scalp and dry skin and hair.
There are a number of different subtypes of sulfates. Let’s have a look at the main ones….
- Sodium lauryl sulfate (often called SLS) - common “standard” used in irritancy testing, against which the irritancy of other substances is compared(1). Researchers have found that the skin is the most vulnerable to SLS as skin tissue readily absorbs it and that it can also produce a dry itchy scalp and dandruff(2). Other research has shown a corrosion of the hair follicle leading to hair loss(3). Pretreatment with SLS has also been shown to cause increased susceptibility to other irritants(4,5).
- Sodium laureth sulfate (often called SLES) – this is the most commonly used “sulfate” in beauty products.
- Ammonium lauryl sulfate - A relative of SLS, ammonium lauryl sulfate is used in some so called “SLS-free” shampoos - however it is also a strong irritant like SLS(6).
People can make their own choice from the evidence available on whether they want to avoid products containing sulfates. However, those with sensitive skin and/or itchy scalp may benefit from using products which are “sulfate-free”.
After considerable research, The Purist Company has chosen to use the following ingredients in place of suflates:
- Sodium lauroyl sarcosinate - from palm, a mild amino acid (sarcosine) derivative cleanser.
- Sodium lauryl sulfoacetate – from palm, a mild cleanser recommended for those who have problems with soap.
- Sucrose cocoate – 100% botanical source anti irritant sugar ester cleanser.
- Lauryl polyglucose – 100% natural source and milder to skin and eyes than the more commonly used decyl polyglucose.
- Disodium cocoamphoacetate – Mildness "standard" amphoteric cleanser from coconut.
- Cocamidopropyl hydroxysultaine – Mild amino acid derivative cleanser delivers superior and milder performance compared to the common and cheaper alternative cocamidopropyl betaine.

2) How do I find out what [A’kin] and [Al’chemy] products would suit my skin and hair type?
The first step is to identify your skin and hair type. Once you know this please refer to the product page on this site and download the easy product selection guide (appears on the left of your screen).
3) Is it safe to use your products with essential oils during pregnancy?
The concentrations of oils in The Purist Company products are safe for use during pregnancy. However to ensure your comfort and peace of mind, we recommend you check with your general medical practitioner.
4) I have eczema. Which products should I use?
Eczema is a chronic inflammatory condition of the upper layers of the skin. The most common things that will trigger eczema are allergies, both food and environmental, as well as emotional and physical stress and climatic changes. The three main common features of eczema that distinguish it from other ailments are dry skin, sore rash and itchiness.
For eczema sufferers, The Purist Company recommends products with least irritancy. Whilist we recommend these products, please remember that each person is unique. We advise for very sensitive skins that you use our testers provided in store to patch test your skin.
Try any of the following:
5) Why is propylene glycol used in cosmetics and is it safe?
Propylene glycol is an ingredient used in numerous cosmetics and toiletries. It is also used as a powerful solvent to prevent creams from drying out. Propylene glycol is a petrochemical derivative and has been shown to cause allergies.
Propylene glycol is not used in any products created by The Purist Company.
6) What are parabens?
Parabens are the most commonly used preservative in cosmetic, personal care and toiletry products. Research has shown that parabens mimic the function of the naturally ocurring hormone, estrogen. Parabens are only estrogenic when applied externally, therefore could be of great concern from cosmetics when applied to the skin. On behalf of consumer safety, The Purist Company have taken the additional precaution of avoiding using ingredients which have been preserved with parabens.
7) Do your products contain alcohol?
The Purist Company do not use what is commonly called alcohol (actual name is ethanol or ethyl alcohol) in any of our formulations.
The reference to “alcohol” on our labels refers to the wax alcohols, behenyl alcohol (made from rapeseed oil) or cetearyl alcohol. Cetearyl alcohol is made from various vegetable oils such as palm and coconut. The differ greatly from common alcohol, which is a volatile liquid.
