How to Choose Cosmetic Raw Materials for Skincare Formulation

How to Choose Cosmetic Raw Materials for Skincare Formulation

Every great skincare product begins the same way - with the right ingredients, chosen for the right purpose, used at the right concentration. If you are making your first batch of handmade soap at home, launching a skincare brand, or sourcing in bulk for a cosmetic manufacturing unit, the decisions you make at the raw material stage determine everything: texture, stability, skin performance, and shelf life.

This guide breaks down exactly which chemicals and ingredients go into the most popular personal care products from bar soap and face wash to serums and lip balms.

This blog explains how to choose the right raw materials with confidence. 

Start Here: The 6 Building Blocks of Every Cosmetic Product

Before choosing specific ingredients, understand the six functional categories that every cosmetic formula is built from. Once you understand what job each category does, selecting individual ingredients becomes much simpler.

Category

What it does

Common examples

Typical %

Base / Carrier

Makes up the bulk of the product

Distilled water, glycerin, oils

50–85%

Emulsifier

Keeps oil and water from separating

Emulsifying wax, BTMS-50, cetearyl alcohol

2–8%

Thickener

Adjusts viscosity and texture

Carbopol 940, xanthan gum, cetyl alcohol

0.5–3%

Active Ingredient

Delivers the product's key benefit

Niacinamide, kojic acid, salicylic acid

0.5–10%

Preservative

Prevents microbial growth

Phenoxyethanol, potassium sorbate

0.5–1.5%

Functional Additives

Improve texture, scent, or performance

Fragrance oils, herbal extracts, colourants

0.5–5%

 

Most beginner formulators focus entirely on actives and completely overlook the structural ingredients - emulsifiers, thickeners, and preservatives. Getting those right is what separates a product that looks and feels professional from one that separates in the bottle or grows mould within two weeks.

Raw Materials by Product Type

Here is a practical reference for the most popular product categories. For each, we list the core chemicals you need, what they do, and how to source them from the right raw material manufacturer or suppliers.

Bar Soap (Cold Process & Hot Process)

Bar soap is made through saponification - the chemical reaction between oils and lye (sodium hydroxide). The formula is simple but the chemistry is precise. Every oil has a different SAP value that determines how much NaOH is required.

 

Ingredient

INCI / Common name

Function

Usage %

Sodium Hydroxide (NaOH)

Sodium Hydroxide

Saponification agent - converts oils to soap

Calculated per oil blend (use lye calculator)

Coconut Oil / Carrier oils

Cocos Nucifera Oil

Base oil - determines hardness and lather

40–60% of oil blend

Olive / Castor Oil

Olea Europaea / Ricinus Communis

Conditioning, lather boost

20–40% / max 10% castor

Shea / Cocoa Butter

Butyrospermum Parkii / Theobroma Cacao

Superfat - adds creaminess and moisture

5–20% of oil blend

Fragrance Oil (Soap-grade)

Parfum

Scent - choose CP-stable grades

3–5% of oil weight

Kaolin / Bentonite Clay

Kaolin / Bentonite

Adds slip, draws impurities, harder bar

1 tsp per 500g oils

Mica / Iron Oxide

CI 77000s

Colour

0.1–1%

Herbal Extract (Oil Soluble)

Varies

Skin benefits - add at trace

1–3%


Lye Safety Reminder: Always add NaOH to water - never water to lye. The reaction produces significant heat. Use stainless steel containers, wear gloves and eye protection, and work in a ventilated space. BRM supplies cosmetic-grade Sodium Hydroxide NaOH at wholesale price.

Liquid Soap & Hand Wash

Liquid soap uses potassium hydroxide (KOH) instead of NaOH. The result is a soft paste that is then diluted with water. Most commercial liquid soaps are surfactant-based (not true soap) - cleaner to formulate, more consistent, and easier to preserve.

● For dry skin face wash: Increase glycerin to 5%, add 0.5% allantoin, reduce surfactant concentration by 5%, use Decyl Glucoside only (no SLES).

● For acne-prone skin face wash: Add salicylic acid 0.5–2% (pH-adjusted to 3.5–4.5), replace standard fragrance with tea tree essential oil 0.3%, add zinc PCA 0.5%.

Face Cream & Moisturiser

A face cream is an oil-in-water emulsion held together by an emulsifier. The emulsifier is the most critical ingredient - the wrong choice leads to separation, graininess, or an unstable product within days. Structure it in phases and always combine your oil phase and water phase at the same temperature (65–70°C) before cooling.

Add Phase B to Phase A at 65–70°C and blend with a hand mixer or homogeniser until emulsified. Cool to below 40°C before adding Phase C. Do not add actives like niacinamide at high temperatures - they degrade.

Face Serum (Water-Based)

A serum is a lightweight, high-concentration delivery system for active ingredients. It penetrates faster than a cream because it has no heavy occlusive layer. pH management is critical - many key actives only work within a narrow pH window.

Important: Any serum containing water must be preserved. Phenoxyethanol at 0.5–1% is the most widely used and compatible option. Oil-based anhydrous serums (no water phase) do not require broad-spectrum preservation.

Acne Treatment & Dark Spot Products

These are the most searched skincare concerns in India. The key is using proven actives at effective concentrations, choosing the right product format, and ensuring pH compatibility between ingredients.

Frequently Asked Questions

Q: What is the most important ingredient to get right in any cosmetic formulation?

A: The preservative, always. Beginners focus on actives and overlook preservation. Any formula that contains water - serum, cream, face wash, lotion will spoil without a properly chosen and tested preservative. Phenoxyethanol at 0.5–1% is the most reliable starting choice for most formulations.

Q: Can I use the same ingredients for face wash and shampoo?

A: Yes, with adjustments. Both rely on surfactant systems, but shampoos typically use stronger anionic surfactants at higher concentrations (SLES at 15–25%) and include conditioning agents. Face washes should use milder surfactants (Decyl Glucoside, Coco Betaine) and stay at pH 5–6. The surfactant system and pH targets are different even if individual ingredients overlap.

Q: Where to buy cosmetic raw materials in India for retail and bulk?

A: BRM Chemicals supplies all the ingredients listed in this guide - from 100g starter quantities for DIY users to 5kg and 10kg bulk packs for brands and manufacturers. Every product comes with Certificate of Analysis (COA) documentation. Free delivery across India. Visit brmchemicals.com/collections/chemicals or contact us directly for B2B bulk pricing.

Q: Is niacinamide and kojic acid a good combination for dark spots?

A: Yes, one of the best. Kojic acid inhibits melanin production, while niacinamide addresses melanin transfer to the skin surface and strengthens the skin barrier. Together at 1–2% kojic acid and 3–5% niacinamide in a serum or cream, they produce faster, more visible results than either ingredient used alone. Maintain pH between 5.5 and 6.5 for stability.

Q: Do I need an emulsifier in a face serum?

A: Only if your serum contains both oil and water phases. A typical water-based serum (HA, niacinamide, glycerin, water) needs no emulsifier - it is a single-phase water system. A hybrid serum with oils (like a vitamin C oil or rosehip oil component alongside water-soluble actives) requires a solubiliser or emulsifier to prevent separation.

Q: What is the minimum order quantity at BRM Chemicals?

A: BRM sells from 100g for retail and DIY users all the way to 5kg, 10kg and bulk quantities for brands and manufacturers. There is no minimum order - which makes BRM ideal whether you are testing a new formula or running a full production batch. Bulk pricing applies from 1kg onwards on most products.
