CSL body wash and body care development: body wash, body butter and lotion

Sector · Body wash & body care

Body wash and body care that does more.

A body wash is now expected to cleanse, care for skin and lift the mood in one step. CSL formulation scientists develop washes, shower oils, in-shower and after-shower care that deliver all three, with the evidence to say so, and the formula is yours.

Body Wash Formulations from Guires CSL

At Guires Cosmetic Science Lab, CSL formulation chemists develop body wash formulations and body care, from sulphate-free shower gels and shower oils to in-shower and body lotions, with mildness and moisture proven by zein, TEWL and Corneometer testing. With more than 10 years of body care experience, the team designs cleansers that leave the skin barrier intact and lotions that measurably improve skin hydration and comfort.

What shoppers look for now

01Skin-first

Shoppers now expect face-level care from body products: gentle cleansing, barrier support and moisture that lasts after the towel.

02Ingredient-aware

More people read the back of the bottle and choose washes by what is in them, and what is left out.

03Scent-led

Fragrance is one of the biggest reasons people pick a body wash. It should make the shower feel like a moment for themselves.

The science

The skin science behind a better shower.

A body wash touches the whole body every day, so small differences in mildness and moisture add up. We design around three areas.

Mild cleansing

Clean skin, barrier intact.

Alkaline soaps and harsh surfactants lift skin’s own lipids and raise its pH, which can leave it tight and dry and shift its microbial balance. Synthetic detergents (syndets) and mild surfactant blends at skin-friendly pH clean well with far less disruption.

Moisture in the shower

Care that stays after you rinse.

Most of a wash goes down the drain within seconds. Moisturising washes and shower oils are built to leave a thin layer of lipids and humectants on skin, and in-shower lotions apply care onto wet skin so people skip a step.

  • Deposition analysisHow much oil or humectant stays on skin
  • Consumer perceptionSoftness, tightness and comfort ratings
  • Foam and rinse testingLather volume, creaminess and rinse feel

Dry & sensitive skin

Comfort for skin that needs more.

Dry, rough and sensitive body skin needs care beyond the shower. Body lotions and creams built on humectants, natural moisturising factors and barrier lipids restore comfort and keep water in for longer.

Clinical evidence

What the published trials show.

Peer-reviewed human studies on cleansing, moisturising and scent. Each links to its PubMed record.

These are published studies on ingredients, methods and routines, not on products we have made. A finished product needs its own testing before a claim goes on pack, and we design that study with you. See the full evidence library

Scent & sensorial

A shower that lifts the mood.

Scent is the first thing people notice and a big part of why they buy a body wash again. We design the fragrance and texture as one experience.

Fragrance with a purpose

Calming, energising or comforting scents developed with fragrance-house partners, within IFRA limits and allergen labelling rules.

IFRAMood-led scent

Texture as the hook

Jelly, cream, oil-to-milk, whipped mousse or clear gel. Texture changes how the shower feels and how much people use.

RheologySensory panels

Foam people trust

Dense, creamy lather is still how most people judge that a wash cleans. We tune foam height, stability and rinse.

Foam testing

Scent that stays on skin

Fragrance longevity on skin after rinsing and towelling, measured with trained panels.

Scent longevity

Every moment of use

Designed for the whole shower.

We test how a wash behaves at each step, not only how it looks in the bottle.

  1. 01Dispense

    A pour or pump that is easy with wet hands

  2. 02Lather

    Foam that builds fast and feels creamy

  3. 03Scent release

    Fragrance that opens in warm water

  4. 04Rinse

    Clean rinse with no film or squeak

  5. 05Towel off

    Skin that feels soft, not tight

  6. 06An hour later

    Moisture and scent still there

FAQ

Body wash & body care questions.

Can a body wash really moisturise?

Yes, if it is built to leave oils or humectants on skin after rinsing. We prove it by measuring hydration after washing, compared with a standard cleanser.

Can you make a sulphate-free body wash that still foams well?

Yes. We combine mild primary surfactants with co-surfactants and foam boosters, then test foam volume and creaminess against your benchmark.

Can you develop a wash for babies or sensitive skin?

Yes. We use mild surfactant systems at skin-friendly pH, minimal fragrance or none, and test on sensitive-skin panels. Published trials show gentle washes can be as kind to newborn skin as water.

Do you create the fragrance?

We work with fragrance-house partners to brief, select and test a scent, or use one you already have, checked against IFRA limits and allergen labelling rules.

Who owns the formula?

You do. We sign an NDA before you share your brief, and the formula and technical file are handed over at the end of the project.

Guires CSL quality, compliance and safety

Every body wash & body care project at Guires CSL runs inside an ISO 9001 certified quality system, with documented methods, calibrated instruments, traceable raw materials and reviewed reports, so the results behind your product can be checked and defended.
