Confirm Cancel. Total Revenue. Suppliers by Area.It is important for those who use makeup products to know what ingredients are contained within them, and a common substance that is often found in many cosmetics is isododecane. This ingredient is an emollient and is often added to products such as mascara, lip gloss, and eyeliner to keep them soft, with the ability to spread easily on skin.

Isododecane is used in many different cosmetic items because of its low instance of side effects and because it cannot be absorbed by the skin, and therefore lacks the ability to elicit significant irritation. Because isododecane is such an effective emollient, is allows products such as lip gloss, eye shadow, eyeliner, and SPF -based cosmetics the ability to glide easily across the skin and spread in an even layer for maximum effectiveness.


Isododecane is also used in the best under eye concealer, where the ability to evenly spread the product is important because of the uneven surface due to wrinkles and fine lines. Another reason why isododecane is used in cosmetic products is due to its non-comedonal properties. This means that it will not clog pores or contribute to the development of acne. Because it is a hydrocarbon, isododecane is highly effective in preventing the evaporation of water from the skin.

This means that the makeup will last longer on the skin, and the epidermis will be better moisturized. While isododecane is generally thought to be safe, you may be wondering whether it will have an adverse effect on your skin type. There are several steps you can take, however, to ensure that you use this ingredient safely.

First, make an appointment with your dermatologist or skin care specialist. Be sure to talk to your doctor about your skin type such as whether your skin has reacted negatively to cosmetic products in the pastif you use any type of medicated washes on your face, and what kind of makeup you currently use. All of this information can help your skin care professional discern whether products containing isododecane are right for you. To date, there have been no recorded side effects associated with isododecane.

However, some experts assert that very few tests have actually been performed with it, and that there is always a possibility of an allergic reaction. When you use products that contain this ingredient, be sure to watch out for any type of unusual developments, such as redness, swelling, or itchy hives that leak fluid, as these may be signs of a severe allergic reaction. Isohexadecane is a synthetic ingredient used as a cleansing agent, skin-conditioning agent, and a te Stearyl alcohol is a natural fatty alcohol that is used as an emollient, emulsifier, and thickener i Acetyl glucosamine is a skin-replenishing ingredient that functions to reduce signs of aging through Isododecane: General Information and Side Effects It is important for those who use makeup products to know what ingredients are contained within them, and a common substance that is often found in many cosmetics is isododecane.

Isododecane Uses Because isododecane is such an effective emollient, is allows products such as lip gloss, eye shadow, eyeliner, and SPF -based cosmetics the ability to glide easily across the skin and spread in an even layer for maximum effectiveness.

Choosing Products with Isododecane While isododecane is generally thought to be safe, you may be wondering whether it will have an adverse effect on your skin type. Side Effects of Isododecane To date, there have been no recorded side effects associated with isododecane.However, will they ever be accepted by the natural and organic market? And can silicones be green? A dark cloud still hovers over this versatile and unique class of ingredients, cast by the private certifiers of natural cosmetics, global regulatory bodies, NGOs and mass media.

They also seek to influence the formulators who endeavor to satisfy these consumer needs. Across the Atlantic, one will not likely find Ecocert silicones or those certified to NaTrue standards.

Pedersen's "Electoral Volatility" Index: calculations (step-by-step)

Formulators may want to evaluate the data themselves for both safety and environmental aspects to make their own judgments. One CIR report from covers dimethicone and a wide assortment of derivatives, 6 while a report covers the volatile cyclics, including D5.

InHealth Canada had cautioned that cyclic silicones have or may have a harmful effect on the environment. However, in the October report to the Minister from the Siloxane D5 Board of Review, the board concluded that D5 did not present a risk to the environment. As a point of interest, in the dry cleaning industry, cyclopentasiloxane D5 is promoted as an environmentally friendly replacement solvent for the chlorinated organic perchloroethylene typically used. The Green Earth Cleaning group licenses a non-toxic dry cleaning that uses liquid silicone, in this case D5, made from silica or sand.

The implication is: What could be more natural? In addition, the U.


Further, an environmental fate chart by General Electric indicates the breakdown of D5 in air by photolysis, in landfill incineration and soil hydrolysis to silica SiO 2CO 2 and water.

This sludge is either incinerated—resulting in carbon dioxide, water vapor and silicon dioxide end products—or degraded in the soil as the same compounds. The principal degradation product is dimethylsilanediol DMSDwhich can ultimately degrade back to carbon dioxide, silicon dioxide and water.

Silicones, at least simple and volatile cyclic and straight chain dimethicones, may be safe as used in cosmetics. They may also generate an environmental impact of low concern.

However, formulators may still seek alternates for marketing initiatives arising from concerns noted previously in this paper or misguided consumer perceptions. But replace them with what? According to Blakely and Van Reeth, 12 silicones in personal care can be divided into five families. Briefly, these are: 1 volatile cyclomethicones; 2 linear dimethicones—i. The latter is a growing range of alkyl-substituted methicones, alkoxylated derivatives, aminosilicones and virtually any hybrid chemistry imaginable.

In considering silicone alternatives, the market typically confines itself to the first two types—volatile cyclic essentially D5 and linear dimethicone fluids. Purveyors of such silicone substitutes focus on the properties of volatility, viscosity and skin feel. Therefore, the first generation of silicone replacements consists of emollients chemically classified as hydrocarbons or esters and ethers. Hydrocarbons: A prominent blend of hydrocarbons modeled after D5 to mimic its feel and volatility is an isohexadecane, isododecane and C alkane blend from Presperse a.

Emollients: Similar to esters and ethers, an olive-based emollient d from Soliance provides a silky feel and sheen to the skin, which absorbs quickly but leaves a distinctly perceptible and light lipid film. As a visual aid, in comparing this emollient with both cyclomethicone and 20 cs dimethicone fluid, the company presents two sensory maps with mineral oil as a negative benchmark.

A similar entry from Clariant e also makes use of olive feedstocks in its light, silky-feeling emollient. Esters and Ethers: Targeting the silky feeling of D5 without its volatility is a diverse group of esters and ethers promoted for their spreading and absorption into the skin.

Smooth closer: The latest in silicones and silicone alternatives

One of the earliest on the scene was based on milk thistle fand consists of a preponderance of unsaturated omega-6 fatty acids that support vitamin F and essential fatty acid claims for skin benefits.

Their spreadability on skin mimics D5 with apparent skin absorption that is quick enough to give the illusion of volatility. Cognis, now a part of BASF, introduced a range g of light emollients to meet the need for cyclomethicone replacements. The line includes high-spreading, nonvolatile emollients that mimic the feel of D5 before it leaves the skin surface, giving the sensation of penetration.

Dicaprylyl ether, a vegetable-derived material, is stable against hydrolysis, and dicaprylyl carbonate is recommended for sunscreen emulsions and pigment dispersions, as it is an effective solvent for crystalline sunscreen actives and reduces the greasy feel of high active preparations.

A heptyl undecylenate h ingredient from INOLEX is derived from castor oil, and is a light, dry emollient designed as a natural alternative to cyclomethicone and mineral oils. This material is also reported to reduce the greasy feel of heavier emollients.

Croda also has introduced emollients j to replace cyclomethicone in skin care.Discussions Activity Sign In. June edited June in Formulating. Trying to figure out a way to formulate liquid lipsticks. The lipsticks go from liquid to a matte dry finish.

A basic ingredient list is: isododecane, Dimethicone, glycerin, castor oil, magnesium stearate, wax, titanium dioxide. Hope you all can help me! It would be greatly appreciated for some help. June Alexandra, What kind of help do you need? Bobzchemist Member, PCF student. Chances are very, very high that you have listed an incomplete ingredient list.

Most manufacturers have done something like this to preserve trade secrets. The essential question you will have to answer first is - what will hold this lipstick on the lips? All of the ingredients you have listed will wipe away at the slightest touch. Robert Zonis, Sr. Formulation Chemist, Beaumont Products "All opinions and comments expressed are my own, have no relation to Beaumont Products, are fully copyrighted, and may not be used without written permission.

Hey Bob and Vitalys. I actually got this formula directly from the website that sells their liquid lipsticks except the wax I forgot to put carnauba wax. I would essentially like to be able to make a liquid lipstick without copying these companies. I must be adding the wrong amount of ingredients or not adding the right ingredients.

I ask because I've shown folks how to find professional-level formulations before, and it's led to a lot of frustration, etc. Chemist77 Member, PCF student.

Bentone Gel ISD V, Isododecane, Dry pigments, vegetable wax, a little non drying oil literally very small quantity to cover up the drying effect of the solventsoptimize the formula and you have a smudge proof formula. PS: I did a mascara with it basic iron oxides only. Do you have a fume hood where you can heat volatile ingredients safely? What will you use to disperse your pigments? How will you mix your formula? January Does dimethicone and isododecane mix well with oils such as castor oil, jojoba oil, and fractionated coconut oil, 1 drop vitamin E, and 1 drop peppermint extract?

I made a formula, containing the above silicones and oils, but there was some oil floating at the top, which didn't mix? I did not heat the above to create my formula, as there were no hard waxes added excluding jojob oil, a liquid wax.

After the filler formula was added, containing diverse minerals and pigments- this was added to the oil phase and mixed. Although the formula was good, there was a white cast left lingering on the top, with the floater oil.Isoparaffins are branched chain hydrocarbons. Isoparaffin ingredients most frequently found cosmetics and personal care products are C Isoparaffin, Isododecane and Isohexadecane. In cosmetics and personal care products, Isoparaffin ingredients may be used in eye makeup preparations, including mascara, makeup preparations, manicuring preparations, skin care and hair care products.

The isoparaffin ingredients function primarily as solvents in cosmetics and personal care products. Isoparaffins are branched-chain aliphatic hydrocarbons.

The C followed by the numbers in the ingredient name represents the number of carbons in the chain. For example, C Isoparaffin is a mixture of branched-chain aliphatic hydrocarbons with 13 or 14 carbons in the chain. Isoparaffin ingredients containing aliphatic hydrocarbons with predominantly a single carbon chain length have names that represent the number of carbons in the chain. For example, Isooctane has 8 carbons, Isododecane has 12 carbons, Isohexadecane has 16 carbons and Isoeicosane has 20 carbons.

The Food and Drug Administration FDA permits synthetic isoparaffin petroleum hydrocarbons to be used directly in some foods. For example, these compounds are permitted in coatings on fruits and vegetables.

Synthetic isoparaffin petroleum hydrocarbons are also permitted to be used secondary direct food additives as defoaming agents. The CIR Expert Panel evaluated that scientific data and concluded that these ingredients were safe for use in cosmetics. Isoparaffin ingredients were not genotoxic. They also tested negative in reproductive and developmental toxicity studies.

Exposure of male rats to Isoparaffin ingredients and other hydrocarbons was associated with effects on the kidneys. The CIR Expert Panel noted that the mechanism of kidney effects in male rats exposed to hydrocarbons is well known and not relevant to humans because it involves a protein made in the kidneys of male rats but not made in humans.

The CIR Expert Panel also reviewed information that indicated that the Isoparaffin ingredients at concentrations used in cosmetics and personal care products were not sensitizers, and dermal effects were not increased when these compounds were applied to the skin and exposed to sunlight.

The Isoparaffin ingredients may be used in cosmetics and personal care products marketed in Europe according to the general provisions of the Cosmetics Regulation of the European Union.

Hydrocarbons, including isoparaffin ingredients, are compounds that contain only carbon and hydrogen. They are generally derived from natural gas and oil. Skip to main content. Search form search. Home Isohexadecane. Messages Overview What Is It?With the palette of silicones available to formulators declining, John Woodruff provides his edit of the best silicones and silicone alternatives for use in personal care.

Arguably silicones and silicone derivatives are the most useful and versatile of all existing groups of cosmetic ingredients. They range in viscosity from volatile liquids to solid pastes and are used as emollients that provide unique sensorial properties, hair conditioning agents, emulsifiers and for the surface treatment of pigments. Unfortunately, for a variety of reasons, there is now a movement away from silicone materials and alternatives are being developed by many ingredient suppliers.

This feature will look at those silicones that still play a major part in cosmetic formulations and at alternatives to those that are falling out of favour. The cyclosiloxanes commonly known as cyclotetrasiloxane D4 and cyclopentasiloxane D5 are used for their anti-static, emollient, humectant, solvent, viscosity-controlling and hair conditioning properties in cosmetic products.

However, concerns have been raised about their toxicity and effects on the environment, and now it is recognised that cyclotetrasiloxane D4 is toxic to human reproduction systems. This has now been amended to include cyclohexasiloxane D6 and it is expected that this restriction will be extended to include leave-on products.

It is not necessary to exclude silicone products and Innospec suggests that Volasil INCI: Dimethicone, trisiloxane provides the right combination of volatility, lubricity and spreadability to impart a dry, smooth application to hair and skin products.

It has a similar volatility to D4, and is recommended for antiperspirants and hair sprays requiring a fast drying time. Volasil DM Dimethisil DM-5 and Dimethisil DM-6 from Innospec are suggested as replacements for D6 in hair and skin products, and as a solvent for active ingredients, as well as a diluent for silicone gums and elastomers. In response to increasing consumer interest in silicone-free products and tighter regulatory restrictions on silicones, Inolex has published a guide to silicone alternatives[1].

It identifies the principal properties of the silicones used in each product category and suggests suitable replacements from its extensive portfolio of cosmetic ingredients. A prime function of silicones in cosmetics is as emollients. They provide a protective layer to the skin and keep it moisturised. They solubilise lipophilic active ingredients and crystalline UV filters and disperse pigments. Emollients play an important role in determining the right skin feel of a cosmetic product and each emollient has its own skin sensory behaviour enabling it to deliver a unique skin feel[2].

From BASF we have Cetiol C5 INCI: Coco caprylatewhich has a similar skin feel to cyclomethicone, supports the incorporation of powders, enhances the solubility of crystalline UV filters and promotes oil deposition from body wash to skin. Cetiol CC INCI: Dicapryl carbonate is described as a multifunctional dry emollient with good pH stability and perfume and propellant solubility, making it suitable for antiperspirant and deodorant applications. Cetiol Ultimate INCI: Undecane, tridecane from BASF is described as an ultra-light, non-polar and volatile hydrocarbon alternative to cyclomethicone with a positive effect on the performance and stability of sun care formulations when compared with cyclomethicone.

Seppic markets a range of alkanes as replacements for volatile silicone oils under its Emosmart and Emogreen trade names, which were described at in-cosmetics Global [3].
