Balea Plex Care Hair Oil

Isohexadecane is often used in products designed to help oily skin. It is lightweight and non-greasy while helping to moisturize. When mixed with silicones, it gives a product a silky feel.

Dimethicone comes in different viscosities:

Depending on the viscosity, dimethicone has different properties.

Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.

This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.

Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

The reason this ingredient is so effective is because it forms a thin film on the skin that reduces transepidermal water loss (TEWL) while supplying linoleic acid to the stratum corneum to improve barrier strength.

The high linoleic acid content is particularly noteworthy for acne-prone skin.

Research suggests that acne-prone skin tends to be deficient in linoleic acid in sebum. Topical application may help replenish this to support a healthier follicular environment and less comedone-promoting sebum.

One randomized study found sunflower seed oil preserved skin barrier integrity in adult volunteers with and without atopic dermatitis (outperforming olive oil).

This ingredient is well-studied, gentle, and an effective emollient suitable for most skin types.

On fungal acne: This ingredient may not be Fungal acne (Malassezia folliculitis) safe. This is because it contains fatty acids with carbon chain lengths in the C11-C24 range.

The ranges of the fatty acids differ so much because it varies batch to batch depending on the cultivar and the growing conditions.

In skincare, it mostly does good plant oil stuff: it softens, sits on the surface to slow water evaporation, and makes formulas feel richer.

Now the honest part. Corn oil isn't studied much in dermatology but we do know it's the go-to vehicle in lab research. So there's decades of research where corn oil was the boring control; it never produced an effect of its own but we also don't have much research on it doing something exciting for your skin.

The one thing worth talking about is linoleic. Acne-prone follicles tend to be low in linoleate and a small study found topical linoleic acid shrank microcomedones by around 25% over a month. That was pure linoleic acid and not corn oil so it should be filed under "promising theory" rather than "proven benefit".

Concentration use can be anywhere from trace amounts to about 14% (the high end shows up in cleansers, moisturizers, body creams, and masks). Corn germ oil, which is basically the same ingredient under a different INCI name, has been reported as high as 25% but most of the time you're looking at low single digits.

Corn oil itself isn't a common allergen. Allergies to actual corn are triggered by corn proteins which is mostly refined out of the oil for cosmetic use. How much of the protein removed depends on the manufacturing process, so it's always better to patch test just in case.

This ingredient does have a comedogenic rating of 0-3, but this doesn't mean a formula with this ingredient will clog pores.

Human testing has proved that any finished product with this ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.

The Malassezia yeast can't make its own fatty acids and breaks down oils around it to feed. Lab research shows the yeast grows when fatty acids in the C11-C24 range are available. Since corn oil is almost entirely C16-C18 fatty acids, this ingredient may not be fungal acne safe.

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.

As a preservative, it works by disrupting the membrane of microbial proteins. This helps keep bacteria and fungi from growing in your products.

The sensitization picture is actually quite assuring as well:of nearly 71,000 patients patch tested with benzyl alcohol, only 0.21% showed a positive reaction with most of them being weakly positive.

This led researchers to conclude that benzyl alcohol cannot be regarded as a significant contact allergen.

It is worth noting this ingredient is classified as one of the EU's regulated fragrance allergens and restricted to 1% in finished products.

Labels must also declare it in concentrations above 0.001% in leave-on products and 0.01% in rinse-off products.

At concentrations around 5%, localized redness and itching can appear as a direct irritant response and not as a true allergic reaction.

Synthetically created Ci 77491 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.
