I am currently making acne gel. (The skin type is acne, both clogged and inflamed, with oily skin). The current formula is as follows: it is the texture of HEC gel (
HydroxyethylCellulose )
Encapsulated Salicylic Acid Liquid 6.6 % (at first I ordered wrong I don't know if the powder form is better for leave-in formulas. But after using it, there is no problem with irritation)
Niacinamide (
B3 ) 4%
Green Tea Extract 3% .
Panthenol 0.5%
glycerin e 3%
Sodium PCA 0.5%
Phenoxyethanol 0.4%
Purified Water qs to 100% The current acne treatment results are quite satisfactory with this active formula. But the problem is that when the gel is applied to the skin, although it spreads easily, it leaves a greasy feeling on the skin for a very long time. So I would like to ask for advice on how to improve the formula to reduce / fix. Such a problem From the study of substances on the web, we think that the substances that are likely to help with this problem should be in 3 This category and which comes to mind from reading the web right now is 1. Group to add smoothness / texture adjustment > aim
Silica 2
ซิลิโคน (
Silicone ) < aim
Dimethicone 3. Add the softness group.
emollient ( ESTER) < aim
Neopentyl Glycol Diheptanoate so I would like some advice. For the formula and my skin type is suitable for which group of substances? and should choose one of the groups or can mix well *** Inquire about on the web write a description
Dimethicone (Very Light, Low-Odor) said "special type Dimethicone, light texture. nearby
Cyclomethicone but not volatile.” "In order of slow to fast evaporation:
Cyclomethicone ,
Dimethicone type Very Light ,
Trisiloxane ,
Dimethicone 1Secs" so I suspect that when writing that dimethicone is not volatile like cyclomedticone So why does the volatile sort sort?
Cyclomethicone Volatile slower
Dimethicone type Very Light
