It’s not just the packaging that’s changing.
The labels on most cosmetics are too, too, and it’s not because they’re trying to be more inclusive or more appealing.
It’s just that the ingredients are.
A new study has found that, in general, some cosmetics contain a higher proportion of ingredients that are “natural”, including those found in plants.
So if you’re thinking of buying a product that claims to be natural, you might want to steer clear of those brands that have been accused of using a synthetic ingredient.
The findings of the study, published in the journal Nature Chemistry, suggest that natural ingredients may be a more important part of a product’s marketing than we might have realised.
The study focused on cosmetics in Europe.
But the authors say they could be applicable to all the countries that make up the EU.
“There are no hard and fast rules in terms of what constitutes a natural product,” says lead author Dr Maria Zaccaro, from the University of Southampton’s Department of Environmental Science and Technology.
“However, if the products are natural, then that’s a really big advantage.
And the advantages of natural ingredients can be huge.”
The researchers looked at samples of 100 cosmetic products, some containing ingredients that were natural, and others that were not.
Some were based on traditional ingredients, like the essential oils of the rosemary plant and the licorice plant.
Others were based purely on synthetic ingredients, such as the artificial colours and glitters used in cosmetics.
But some were based entirely on synthetic compounds.
The synthetic compounds in cosmetics may be used to create a more palatable product, so they may be considered more natural if they contain natural ingredients.
“So we asked people to guess what the ingredients were in these products, which is probably the most honest thing they could do,” says Dr Zaccaco.
They found that products with synthetic ingredients contained significantly more natural ingredients than those without.
“For example, the synthetic compound called alkyl benzoate was found in 70 per cent of products,” she says.
“And alkylated benzoates are not used as a preservative.
So it’s the same in terms.
The alkylene compounds are also found in some skin care products, so we think this is related to the synthetic compounds.”
And while alkyls are naturally occurring, they’re often synthetic, and are therefore less suitable for the skin.
But in the case of cosmetics, the researchers found that the synthetic alkyldisones were still present in about half of products.
But there’s a problem with using synthetic ingredients to create products with natural ingredients: they can be toxic.
“It’s very important that the products we’re using are safe,” Dr Zacaros says.
That’s why she and her colleagues looked at the effects of the synthetic ingredients on the skin of volunteers.
“We put the volunteers into a test where they were given a variety of different cosmetics and then they were asked to apply these products over their skin.”
So they were able to see what effect they were having on the participants’ skin.” “
Then we measured their skin reactions to the cosmetics in general.
So they were able to see what effect they were having on the participants’ skin.”
In the study they found that participants who had used cosmetics containing synthetic alkenes had higher levels of reactive skin proteins in their skin compared to participants who didn’t use synthetic alkens.
“This could potentially lead to allergic reactions in people who have had allergic reactions to certain substances,” Dr Zacas says.
She adds that the results showed that the higher levels in the participants who used synthetic alkynylbenzoates were more likely to develop an allergic reaction to these substances.
“If you’re using a product, there’s probably some chemical that’s going on there that’s potentially toxic,” she warns.
So what are some of the ingredients in these synthetic products that are known to cause skin irritation?
According to the study authors, alkylflages and alkylaic acid are two of the most common.
“Alkyls and alkenylbenzates are naturally derived from the bark of the aloe plant,” says Zaccarca.
“These two ingredients are the most likely to cause irritation to the skin.”
However, the research team also found that alkylpyrrolidones and alkeolamin were also found to be among the most commonly used synthetic compounds, which they explain is probably because they have the most active ingredients.
Alkeolamines are often found in fragrances and perfumes, and alquinolones are used in hair dye, mascara, and eyeliner.
Alkylphenols are used as preservatives, and have also been linked to allergies.
The researchers also found a link between the use of alkyltetrahydrofolate and the formation of comedones, skin reactions that
