Have you ever had the experience of using the main moisturizing lotion, but you always feel that your face“be very stuffy”Or, after applying sunscreen, the makeup will always be stuck in powder? In fact, behind these skin sensation issues, they are often related to the skin care products“Oil raw materials”concerning——And today we are going to talk about isononanoate (abbreviated as isononanoate)JS ININ）It means being able to balance“Moisturizing power”and“refreshing feeling”The key players.

1   Isononanoate Isononanoate(ININ)Introduction

Isononanoate is a synthetic ester raw material, which is generated by esterification reaction between isononac acid and isononanol. It belongs to the typical category“Branched fatty acid ester”.

From a structural perspective, its molecular chains are“Branched shape”(rather than a straight chain), this characteristic directly determines its core advantage in daily chemical formulas——It not only retains the moisturizing and hydrating ability of oils, but also eliminates the thick and sticky feeling of traditional straight chain oils, which has been frequently used in skincare and makeup products in recent years“Multi functional grease”.

II   4 Major core features

1.  Due to the strong fluidity of the branched molecular structure, isononyl isononanoate can quickly spread and absorb on the skin, with almost no“Oil film sensation”For example, adding the same5%The use of straight chain esters (such as butyl stearate) in fats may feel“sticky”But when using isononyl acid isononyl ester, the skin feels like“Dry and smooth”Yes, this is also the reason why it is often used in oily skin care products and summer sun protection.

2.  as“Formula blending agent”Isononanoate can react with vegetable oils (such as olive oil and jojoba oil), mineral oils, silicone oils (such as cyclopentasiloxane), and active ingredients (such as vitamins)EHighly compatible with niacinamide, there will be no layering or clumping issues. For formulators, this means they can flexibly combine multiple functional ingredients without having to worry about“Mutual exclusion of raw materials”to be worried.

3.  Compared to some easily oxidizable vegetable oils such as flaxseed oil, the chemical structure of isononyl acid isononyl ester is more stable and can withstand high temperatures45℃It is not easy to decompose in a light environment and does not produce any odor. This can reduce the storage time of skincare products“Risk of deterioration”Indirectly extending the shelf life of the product.

4.  Although not“Main penetrant”However, the molecular size of isononyl acid isononyl ester is moderate and can form a layer on the surface of the skin“Thin and lightweight lipid membrane”It can help the subsequent active ingredients (such as whitening and anti-aging ingredients) penetrate better, and reduce the irritation of active ingredients to the skin.

Many people will mix isononanoate with mineral oil and octanoic acid/Capric Triglycerides（JS GTCC）Confused, in fact, the positioning differences among the three are very obvious:

Simply put: Pursuit“cost-effective+refreshing skin feel”Choose isononyl acid isononyl ester; pursuit“Extremely gentle”, chooseJS GTCCPursuing“Low cost basic moisturizing”Choose mineral oil.

III   practical application

1.  Skin care products: from lotion to essence, suitable for the whole scene

Oilskin lotion/Face cream: add3%-8%Isononanoic acid isononanoate can moisturize while avoiding“Stuffy acne”For example, many flagship products“Refreshing Hydration”30% men's face cream will regard it as the core oil;

Sunscreen products: When used in combination with silicone oil, they can improve sun protection“Rubbing mud sensation”Make the skin feel smoother and improve the dispersibility of sunscreen;

Essence Oil/Repair essence: add a little（1%-3%）Can neutralize high concentrations of active ingredients“Sticky feeling”For example, essence containing retinol and fruit acid is often used to balance skin feeling.

2.  Makeup: Make the base makeup more snug and remove makeup more gently

foundation make-up/Air cushion: Add5%-10%Isononyl isononylate can improve the extensibility of foundation, make foundation make-up easier to push, and reduce powder sticking and mottle;

cleansing oil/Makeup remover cream: as“Auxiliary solvent”Can help dissolve waterproof cosmetics (such as eye black and eyeliner), and reduce the“tightness”.

3.  Body care: Summer body lotion“Refreshing Secret”

If the body lotion used in summer is too greasy, it is easy to stick to clothes——Isononanoate can help maintain body milk“Moisturizing sensation”At the same time, finish coating 1 You can wear clothes in minutes without worrying about sticky residue.

4   summary

Isononanoate is not included“Internet celebrity raw materials”But it's in the formula“Practical faction”It doesn't have a stunning single effect, but it can achieve“Optimize skin texture, enhance compatibility, and stabilize formula”To elevate the user experience of the product to a higher level.

If you are a formulator, you may want to try using it with different active ingredients; If you are a consumer, you can also check the ingredient list when choosing skincare products next time——encounter“Isononanoate Isononanoate”Most likely, it can be avoided“Sticky and stuffy acne”The pit
