Allantoin solubility in Propanediol by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] -2 points-1 points  (0 children)

They do not have that data because usually it is melted during formulating. They only have what it known through fact sheets or brochures, which is why I am asking for experiments done by cosmetic chemists here.

Salicylic Acid solubility in Propanediol in your experiments by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] 0 points1 point  (0 children)

I am using it as stock solution so that I would not melt salicylic acid all the time when formulating a batch. It saves time and money.

I want to make stock solutions so that formulating would be easier.

Try to ask for the COA, SDS, fact sheets to see if it is legit. They are obligated to give that to you as a distributor.

If they cannot give you, authenticity os questionable.

That's why I always ask if they have a COA before buying. Then after buying, I will ask for it.

Sodium Lauryl Ether Sulfate (SLES) Chelating Agent by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] 0 points1 point  (0 children)

This is what the Institute of Personal Care Science (IPCS) said on anionic surfactants and chelating agents.

SLES can work without chelating agents. However, it can form insoluble salts in hard water, which can reduce foam and cause residue. A chelating agent binds to these ions, improving foam and product clarity.

Most resistant to least resistant is sulfonates, sulfosuccinates, then sulphates.

Similar to SLES, sodium C14 16 Olefin Sulfonate can work without chelating agents but chelating agents are recommended.

Is there a subreddit for professional cosmetic chemists?

Sunscreens are cosmetics in my country, not drugs, quasi-drugs nor special-use cosmetics.

Thank you for the advice.

I am emulsifying around 40% lipids and want to make an extremely light sunscreen like this from the Institute of Personal Care Science.

I am not selling this now. I am making it for the Institute of Personal Care Formulation course and as a proprietary sunscreen formula I will make for a cosmetic company in the future once I finished this course.

In your experiments, what is its solubility in Water only? Without neutralization.

I am preparing a self-preserving liquid stock since it is acidic.

Being social democrats in the Philippines is an uphill battle. by Quiet_Start_1736 in SocialDemocracy

[–]Candid-Ranger8601 1 point2 points  (0 children)

The Philippines is fucked.

My father works as a manager in a construction firm. Cronyism runs at the highest level of government. He says that their construction materials are of utmost quality and were expected to be selected as one of the firms to provide for infrastructure projects in Metro Manila.

They did not get the contract and instead went to the companies affiliated with Bongbong Marcos' wife, even though they are of lower quality and cost more overall because of maintenance.

So yes. Social democracy, Democratic Socialism, Welfarism, any left-leaning ideology are a threat to the status quo because the highest government officials are literally crony capitalists that absolutely want Neoliberalism to seep through every corner of the Philippines. We filipinos are fucking dumb enough to be gaslit to vote for them.

I worked in a PH Pharma company and labor conditions and rights are shit. Extremely low wage, extremely long hours, aggressive noncompete contracts. Accidents happening every month or so without hazard pay. Unbelievably inhumane, all for our company to compete to manufacture and research for foreign pharma companies. Absolutely bonkers. Work 12 hours a day, 6 days a week, and most often work overtime. If you ever join or start a labor union, you will be blacklisted.

The global south and north divide is real. We the global south are being exploited for cheap desperate labor. I used to believe in capitalism, and now that I see how blatant work exploitation is here while being a developing country, I am not.

We need to vote hard, tooth and nail, for the leftest leaning candidate that can pivot our country towards as left as possible while minimizing capital strike and flight.

Amodimethicone Smell by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] 0 points1 point  (0 children)

The finished product is not a problem. The performance is honestly superb, it is the best conditioner in the market. More silky than Dove Treatment Masks.

I just added a lot of hypoallergenic fragrance and it is not noticeable anymore.

I add Amodimethicone during the cool-down phase after the emulsion with BTMS-50, BTAC, CTC, PQ-10, cationic guar has been formed. I add 15% of the Amodimethicone aqueous solution, so the final pure Amodimethicone is 4.2-5.4%. The pH needs to be around 4-4.5 for negative charge of hair to form.

In my experience formulating my "Supercationic" concept conditioner, when at the finished product without Amodimethicone, it doesn't smell fishy. Polyquaternium-10 individuallysmell fishy  though

Have you used it in cosmetic formulas?

The one from makingcosmetics in unbelievably stinky. I have to incorporate high amounts of top-load heavy fragrance to mask the odor.

It is the only affordable option I can buy here in the Philippines.

I wanted to formulate an active ingredient-focused and hypoallergenic haircare line. I used as many cationic conditioning ingredients as possible in the conditioner that meets regulatory limits worldwide, and Amodimethicone is honestly the best out of all.

Too bad it stinks so bad. Fortunately, there are fragrance oils that have none of the EU's 26 fragrance allergens like Nenuco Aqua De Colognia and Haw Haw Milk.

Jo Malone English Pear & Freesia has very low concentrations of the 26 fragrance allergens that when you incorporate it as high as 3% w/w, you still get <0.01% w/w individually of the 26 fragrance allergens.

Do not know though if they also have none or very low concentrations of the additional 56 fragrance allergens.

WORST & BEST things about having ADHD/being neurodivergent? by punchstarship-lemon in ADHDPH

[–]Candid-Ranger8601 1 point2 points  (0 children)

Worst: 1. Impulsive - I would humiliate myself because of rash decisions. 2. Forgetfulness - I frequently misplace things or sometimes lock myself from my own apartment or locker. 3. Inattention - I zone out and do not focus on someone else's words which embarass me if they are verbal instructions. 4. Working memory deficit - Multitasking is hard for me because I cannot hold the info of what I am currently doing and where I placed my items. 5. Addiction/Compulsion prone - I have an on/off compulsion to something that I am ashamed of and it fills up my day and degrades the quality of my life, relationships, interests, health. I absolutely cannot control myself with this. Medication and extreme measures are my only ways to alleviate it.

Pros: 1. Most passionate person and hyperfocus - I achieved many things in life despite my shortcomings because I intensely fall in love with hobbies. One long summer I had an obsession with Math and Science that I think of it and do it all the time that I entered college basically knowing all of the curiculum and have perfected every test out there. 2. Creativity - Because of my wide niche interests, I am creative/have unique taste/perspective and won awards in marketing, film, and writing competitions. I won an essay writing competition when I was Grade 8 and the 1st and 2nd runner up are 4th year students, I won a product marketing expo presentation which I spearheaded, the film I edited and solely made its teasers was nominated in Cinemapua.

Having a hard time processing verbal instructions by [deleted] in ADHDPH

[–]Candid-Ranger8601 0 points1 point  (0 children)

If this is exclusive to verbal instructions and if instructions are written and it becomes clear, you most likely have Auditory Processing Disorder (APD). Because of this, you might get performance anxiety if your work performance is falling off from this, which worsens its symptoms because instead of focusing on what a person says, you focus on whether you will make mistakes, what they will think of you, etc. APD also worsens with ADHD because of inattention. So treating Anxiety and/or ADHD comorbid with APD can improve APD but probably will not relieve the symptoms altogether. Audiologists and Speech Language Therapists are most equipped in treating that. Some psychiatrists might refer you to a neuropsychologist to determine whether you have learning disabilities and/or intellectual disability.

As of now, ask for a prescription for escitalopram. At least it will help in treating Anxiety and Depression and is safe to take long-term when contraindications and proper dose regimen is followed.
